Support Community Gardens with City Council

The cost of fresh fruit and vegetables is going through the roof. Many children have lost their connection to the earth and its seasons. Seniors have become increasingly isolated. People from all walks of life have little or no access to garden space, whether apartment renters or folks who own condos, townhomes or McMansions. Community gardens bring people together, provide opportunities for socialization and education on healthy gardening and eating.

Please contact the Novato City Council and let them know you support community gardens. The Garden Committee has identified two good potential locations. Novato covers a large geographic area and one garden would be a great start, whichever location they choose.

For little cost to the city, it will bring great benefit to Novato residents. Individuals including seniors and families with children will be able to experience the pleasure of gardening, the health benefits of garden exercise and fresh, pesticide-free food.

The Novato Community Garden Committee has been working with the city and other groups to find a permanent location. They received grant funding through the Kaiser Foundation and Supervisor Judy Arnold that will help the gardens get off the ground. Ongoing funding for insurance and water management will be provided by nominal annual garden plot rental fees.

The Grapevine In Chile#8217;s Casablanca Valley cool is the operative word for whites

Chile first made its mark in the U.S wine market with inexpensive wines, many of them red, from the countrys fertile central valley. Because of the valleys deep soils and warm, dry climate, growers were able to ripen large crops, so it was feasible to turn out lots of low-priced wine.

As was the case when the wine industry matured in California, Chilean vintners have reached a point where theyre exploring new viticultural areas that are more suitable to particular grape varieties. In the case of grapes such as chardonnay, sauvignon blanc and pinot noir, the plantings have been migrating to cooler areas.

Cooler climes

One of the prime areas for cool-climate grapes is the Casablanca Valley, which is northwest of Santiago and less than 20 miles from the Pacific Ocean. The cold Humboldt Current runs off the coast, so the sea produces a cooling effect, with morning fog. Chardonnay is the most widely planted grape, with sauvignon blanc a strong second and increasing. Pinot noir does well, too, and merlot is grown in some of the warmer sites. Theres even a little syrah, which is showing promise.

There are only a few wineries based in Casablanca; most of the roughly 10,000 acres of vineyards are farmed by wineries based elsewhere in Chile or by private growers. The area got its start when Pablo Morand%26#233;, who was then working for Chilean giant Concha y Toro Winery, started looking for a growing environment similar to that of Carneros. He found what he wanted in Casablanca and planted about 50 acres.

Rapid viticultural expansion

Planting expanded rapidly in the 1990s. Among the vintners who discovered Casablanca was Agustin Huneeus, a Chile native who owns Quintessa Estate in the Napa Valley. He started Veramonte, a winery that exports most of its production to the United States and is well-known for its crisp, vivid%26#8212;and attractively priced %26#8212;sauvignon blanc.

Kingston Family Vineyards is another Casablanca winery with a California connection. The family patriarch, Carl Kingston, a copper miner from Michigan, went to Chile in the early 1900s in search of gold. He settled in Casablanca in the 20s and started raising cattle. In the mid-1990s, his great-grandchildren, Courtney and Tim, who had been raised in the States, came up with the idea to plant a vineyard. Courtney, a Stanford graduate who lives in the Bay Area, wrote a business plan.

A viticultural consultant told the family that pinot noir%26#8212;a grape that wasnt grown much in Chile%26#8212;would be a good match for the site. Planting began in 1998, and there are about 200 acres now. Most of the fruit is sold, although the family produces about 3,000 cases, with a focus on pinot noir. Byron Kosuge, who spent much of his career at pinot specialist Saintsbury in Carneros, makes the Kingston wines.

White wines shine

Currently, the best wines from Casablanca are the whites, which have a lot of freshness and racy acidity. The 2007 Veramonte Sauvignon Blanc ($10) is a good example. Its zippy and bright, with citrus and white peach flavors and great acidity. Kingstons 2006 Cariblanco Sauvignon Blanc ($16) offers some grassiness and passion fruit. The 2007 Cono Sur %26#8220;Vision%26#8221; Sauvignon Blanc ($15) is another good one; its fresh and crisp, with melon and citrus flavors and a hint of grassiness.

There are some good chardonnays, too, in a range of styles, although all have plenty of lively acidity. The 2007 Cono Sur %26#8220;Vision%26#8221; Chardonnay ($15) is made in a fresh, racy style, with flavors of pear and white peach. (The 2006 is whats currently available.) The 2006 Carmen Reserve Chardonnay ($16) has a similar profile. The 2006 Casa Lapostolle Cuv%26#233;e Alexandre Chardonnay ($25) is also very fresh but a bit more complex, with mineral notes and a long finish. For a creamier wine, theres the 2006 Veramonte Chardonnay ($10), which is ripe and a little tropical.

Pinot finds its footing

Although theres a lot of excitement about pinot noir from Casablanca, I think the results so far have been uneven. Theres not a lot of history with the grape in Chile, so growers and winemakers are still feeling their way. Some are hiring consultants from California, like Kosuge and Paul Hobbs, who is working with Veramonte on an as-yet-unnamed super-premium pinot. The Veramonte wine, which will be released in September, is extremely promising: dark, concentrated, spicy and structured, yet graceful and very pinotlike.

Kingstons pinot, called Alazan, is also on the right track. I havent tasted the current release, from 2006, but the 2004 was bright, spicy and a little earthy, with a supple texture. And Cono Surs best pinots are made from Casablanca grapes: the 2006 20 Barrels ($25) and 2006 Ocio ($50).

Casablanca is showing the sort of diversity thats possible in Chile. Well be seeing more of that diversity as plantings expand in other cool regions, like Leyda near the coast, Limar%26#237; in the north and Bio Bio in the south.

Healthy business Snake oil or cureall Nutrition supplements are booming in Utah

Five days before the 2005 Super Bowl, nobody knew if wide receiver Terrell Owens would play.

Six weeks before, the Philadelphia Eagles star broke his leg and severely sprained his ankle. If he played in the Super Bowl, his doctors warned, he could suffer a career-ending injury. Owens knew he would play. God had a plan for him, he said.

Plus, he’d been drinking noni juice.

“It’s weird tasting, but it’s supposed to make you heal,” Owens said. “I don’t know where the juice is from.”

Soon the world was wondering the same thing. Before long, the phones at Provo-based Tahitian Noni International, the world’s top maker of noni juice, were ringing off the hook.

“It was a totally unsolicited endorsement,” recalls Shon Whitney, TNI’s general manager of North American sales. “It was great.”

True to his word, Owens played, catching the ball nine times for 122 yards. The press declared it a modern-day miracle.

As miraculous as Owens’ recovery was, the story of the company that brought noni juice to the world is perhaps even better.

In the mid-1990s, Utah food scientist John Wadsworth traveled to Tahiti to find a fruit Polynesian healers had supposedly used for thousands of years.
Story continues below

After days of searching, Wadsworth stepped from his Jeep, tired and discouraged. Taking in a sunset, his eyes followed the rays of sun to a valley below and a lush grove of wild noni trees.

“As I was struck with this beauty,” Wadsworth recalls on the company Web site, “a very powerful impression came to me, ‘This fruit has been preserved from the world, and now is the time to take it to the world.’ ”

So Wadsworth took the fruit home, and by 1996 the first bottles of noni juice were ready for mass consumption. Rumors quickly spread that the sour, purple juice cured everything from AIDS to cancer. A dying man in Nevada ordered bottles by the caseload to bathe in. Others rubbed it on horses to cure festering wounds.

By 2001, TNI %26#151; or Morinda %26#151; was raking in the money, with annual sales topping $300 million.

The next year, an independent research marketing firm declared that “fewer than 10 private companies in the history of the world have been able to equal Tahitian Noni International’s first six years of growth.”

Today, TNI has 1.3 million distributors in 73 countries and an annual revenue of $550 million.

Dietary supplements %26#151; herbs, noni juice, multivitamins %26#151; were once the domain of hippies and fitness freaks, backpackers and chiropractors. Not anymore.

Now everyone from Terrell Owens to the next door neighbor uses them. In fact, one in five Americans takes some sort of supplement daily. A third have used herbs at least once to treat everything from colds to headaches, depression to diarrhea.

“It’s become more mainstream. More medical professionals are embracing our products,” says Rick Evans, a spokesman at industry giant Neways.

Supplements are big business in Utah, to the tune of $2.5 billion to $4 billion a year. That accounts for between 10 percent to 20 percent of the U.S. nutrition-supplement market.

It is also the state’s third-largest industry, according to the Utah Natural Products Alliance, three times the size of the ski trade. All told, there are 130 dietary supplement companies in Utah, 30 percent to 40 percent of which are in Utah County.

“You have a natural health highway along I-15,” says Loren Israelsen, executive director of the natural products alliance. “Clearly, the dominant area is Utah County.”

In downtown Provo, Nu Skin towers over Center Street, its headquarters a 10-story building of blue-tinted glass. Nu Skin, which sells supplements under its Pharmanex brand, made more than $1 billion last year. It is one of Utah County’s largest employers.

A stone’s throw from I-15, near a Springville exit, Neways’ corporate headquarters literally sparkle on sunny days. Neways, which also makes personal-care products, made about $625 million last year. It is Springville’s second-largest employer.

And tucked away in the Riverwoods Business Park, not far from some of Provo’s most expensive homes, is the opulent headquarters of Tahitian Noni International, which employs about 600.

These companies operate quietly. Most do little advertising, because their sales are done door-to-door through multilevel marketing. They give generously to their communities, pay millions in taxes, employ thousands of Utahns and support a dozen allied industries, from those who make vitamin bottles to truckers who haul cases of juice and pills.

And yet the industry goes largely unnoticed.

“There are a whale of a lot of people in Utah County who have never heard of Nature’s Sunshine, even though it’s the oldest and one of the largest supplement companies in the state,” Evans says.

The supplement industry may be one of the state’s best-kept secrets.

“We’re an underappreciated and misunderstood part of Utah’s economy,” says Charles Allen, a Nu Skin vice president.

Misunderstood, Allen says, because as important as the industry is to the state, it is often stigmatized and shrouded in suspicion.

“People say we’re not legitimate,” Allen says. “It’s absurd.”

Some think herbs don’t work. Others say supplements are overpriced. And some say the magic elixirs of the trade %26#151; noni juice and Xango juice, to name two %26#151; are nothing more than snake oil, that the men behind them are hucksters, duping the gullible and vulnerable.

“Truth be told, a lot of wool is being pulled over people’s eyes,” says Will McClatchey, a University of Hawaii scientist who has studied noni juice for 10 years.

There are also suspicions that multilevel marketing companies are actually illegal pyramid schemes. (See accompanying story.) While not all supplement makers in Utah are multilevel marketers, many are, especially in Utah County.

“Utah has a reputation for schemes and scams. I’m not sure why or even if it’s accurate,” says John Petersen, a Nu Skin spokesman. “When a Nu Skin distributor comes knocking on your door, people can be a bit hesitant and may wonder if we’re one of those schemes. It’s hard to get away from that stigma.”

It doesn’t help matters that some of Utah’s largest supplement makers have had a run-in or two with the law, mostly for making false claims.

Other headlines have been equally embarrassing. Neways’ founders, who no longer run the company, were convicted earlier this year of tax evasion. And in a recent Forbes article, allegations surfaced that a paid speaker for Tahitian Noni International had given up his medical license after several women accused him of sexual misconduct.

Jon Taylor, a former Nu Skin distributor, calls the industry “the dark underbelly of the state.”

Stephen Barratt, a retired Pennsylvania psychiatrist who has written extensively on supplements and multilevel marketing, calls the industry “a total scam.”

Whether those charges are fair is open to debate. What is certain is that the industry is under fire.

Earlier this year, the Institute of Medicine released a 327-page report urging Congress to require supplement makers to prove their products are safe. That report came after the FDA’s decision to ban ephedra, an herbal stimulant that has been linked to anywhere from 20 to 150 deaths.

To consumer advocates, ephedra %26#151; an herbal cousin to a chemical used to make meth %26#151; is proof enough the law governing the supplement industry is not working.

That law, the Dietary Supplement Health and Education Act of 1994 (DSHEA), was sponsored by Sen. Orrin Hatch, R-Utah, who has received hundreds of thousands of dollars in campaign contributions from the industry since 1994.

Under the law, supplements are not subject to FDA approval, and the companies behind them do not have to report adverse side effects.

The net result of DSHEA, critics say, is an industry that is almost entirely unregulated.

There are, for example, no established quality-control standards, meaning that what’s on the label isn’t always in the pill.

“You have companies who put a little bit of, say, echinacea in a tablet, and the rest is fairy dust,” says Pharmanex president Joe Chang. “And so someone takes that pill and thinks echinacea doesn’t work. It hurts the whole industry.”

Now everyone from Sen. Ted Kennedy, D-Mass., to the publishers of Consumer Reports magazine want the law strengthened.

Supplements, they say, should be held to the same research and quality control standards as drugs.

“That would have a fairly dramatic impact on the industry. But it’s highly unlikely that DSHEA would be yanked. It’s a worst-case scenario,” says Grant Ferrier, an editor at the leading trade magazine Nutrition Business Journal.

Clinical studies on a single drug average $130 million. While drug companies can recoup those costs, supplement manufacturers can’t.

“You can’t patent products that grow on trees,” says Israelsen, from the natural-product alliance. “Why would one company spend millions of dollars in research and development, only to have a host of imitators pop up as soon as they release their product?”

“If you impose a drug-like standard, there won’t be any dietary supplements. The industry would shut down.”

And that would spell disaster for Utah’s economy.

On a quiet side street next to Nu Skin’s headquarters, there’s a squat, nondescript building. Inside, the walls are decorated with watercolor paintings of herbs. Scientists in white lab coats peer into microscopes. Jars containing herbal roots line the shelves.

This is the Pharmanex lab. There are two others like it in China. Across the street at company headquarters, nine stories up, is the office of Pharmanex president Joe Chang.

Today, Chang is seated in front of several glass shelves stocked with Pharmanex products %26#151; LifePak, the best-selling multivitamin; CordyMax, the stamina booster; and BioGinkgo, which helps improve memory.

When he is asked a question, he nods before it is over and answers with a knowing smile. He’s heard them all. He knows what the critics say. There are so many misconceptions, he says.

“Unfortunately it’s one of the challenges of the industry,” he says. “We suffer from the negative publicity.”

What most people don’t understand, he says, is that herbs have been used for centuries, and that they have long been a part of Utah’s economy.

The pilgrims carried them on the Mayflower, the Mormon pioneers chased away ulcers with cayenne pepper and the American Indians treated headaches with the bark from willow trees.

Even pharmaceutical companies like Parke-Davis and Merck relied on herbs in the early 1900s to make their pills.

Then came World War II and the rise of synthetic drugs.

Before long, doctors had stopped prescribing herbs, pharmacies dropped them, and health insurers wouldn’t reimburse those who bought them.

In the mid- to late-1960s, herbs made a comeback, thanks largely to three Utah County companies %26#151; Nature’s Way, Nature’s Sunshine and Nature’s Herbs. Those three start-ups would eventually spawn an entire industry.

“Utahns have a natural sympathy for herbs. It’s a Mormon cultural tradition. The pioneers used them, and the (LDS scriptures) make reference to them,” the UNPA’s Israelsen says.

Utah’s dry climate also proved ideal for growing and storing herbs. Its location was perfect for distribution. And its pristine mountains and streams looked great on brochures and catalogs for companies hawking “all natural” products.

As the demand for herbs and other supplements increased, the government, which viewed supplements as a drug, stepped up efforts to ensure safety. The emerging supplement industry cried foul, claiming the FDA was forcing their products from the shelves.

“The FDA was inconsistent and predatory. They were going after products they didn’t like, not because they were unsafe, but because they didn’t like the claims they were making,” Israelsen says.

A massive letter-writing campaign followed, culminating in the passage of the now-controversial DSHEA, which re-defined supplements as a class of food. At the time, an estimated 130 million Americans were using supplements on a daily basis.

Under the law, supplement makers couldn’t claim their products cured or prevented disease %26#151; but they could say they helped people feel better.

“Before that you had a sort of ad-hoc, patchwork approach to regulation. After DSHEA we knew how we were able to make claims, what we could and couldn’t say,” says Rich Hartvisgen, Nu Skin’s vice president of global regulatory affairs.

A year after the law passed, Chang and others from the pharmaceutical industry helped start Pharmanex. The idea was to use the same standards of research and quality control to make supplements.

Today, Pharmanex is at the forefront of scientific research in the supplement community.

For each new product Pharmanex spends 18 to 24 months and $1 million in research and development, Chang says.

If a product doesn’t work, they scrap it. “You can’t pay lip service to science,” Chang says. “You need the scientists, you need the labs. On a business level it gives us a different feature. We’re not just another supplement company out there putting pills in bottles with pretty little labels.”

Chang recognizes that his industry is not without scoundrels and scams, and that even his parent company has had a few scrapes with the law %26#151; but that is the past.

Pharmanex, with its emphasis on science, is the future.

“I’m sure there are still some scams and schemes out there, but the industry has changed,” said Nu Skin’s Petersen. “We’ve been around 20 years and we’ve shown there’s a legitimate way to do this.”

Life is good at Tahitian Noni International.

You can tell that before you step inside corporate headquarters.

Go upstairs, past the call center, where hundreds of college students are working, speaking more than a dozen languages to distributors across the world, to people who believe they have found the elixir of life.

Cross the hall, to the founders’ offices. The carpet is thicker here, the color of a rich cream. The offices are huge %26#151; the size of your living room. Check out the fireplace, the fine leather furniture, the view.

The founders have built a park behind their offices, 25 acres big, 251 varieties of flowers, exotic trees, a circulating trout stream and a rock garden.

From a Lindon warehouse to this, in less than 10 years.

An impressive success story, to be sure.

But if supplement makers were required to meet the same research standards as drug companies, noni juice may have never reached the market. After 10 years of research, scientists are still trying to find a medicinal value in the juice.

So should supplements be held to the same standards as drugs?

Chang, at Pharmanex, doesn’t think so. “Drugs have to go through testing because they are synthetically made. These are brand-new molecules,” he said. “Foods have been around forever.”

In the 10 years since Hatch’s law passed, the FDA has only recalled one supplement %26#151; ephedra. And a Utah federal judge in April struck down the ban on dietary supplements that contain ephedra.

“To me, that’s a testament to the general safety of nutritional supplements,” says Nu Skin’s Hartvisgen.

To Hartvisgen, ephedra is proof the law is working. Grant Ferrier, the editor at Nutrition Business Journal, says the stimulant has only been linked definitively to 20 or 30 deaths %26#151; not 150, as many contend %26#151; over a 10 year period.

“Even in the most exaggerated case, that’s nothing compared to the 100,000 people who died last year from taking pharmaceutical drugs.”

According to the 1998 book “Bitter Pills,” by investigative journalist Stephen Fried, “more people die each year from adverse reactions to prescription and over-the-counter medications than succumb to all illicit drug use.”

“Illicit drugs kill anywhere from 5,000 to 10,000 Americans a year,” Fried writes. “The estimates for U.S. deaths from legal drugs have ranged from 45,000 to over 200,000 per year.”

Put another way, more people die each year from drug reactions than are killed in automobile accidents.

“You could have 100,000 FDA inspectors and still have problems. There will never be a perfect system,” Israelsen says. “Could something like ephedra happen again? Of course it could, to the same degree it could happen with any class of food or drug.”

It is unlikely DSHEA will be drastically changed, at least not without a fight.

Hatch has vigorously defended the law he helped write, and he has been well paid for his support. His son is also a paid lobbyist for the industry.

Rep. Chris Cannon, R-Utah, who calls Utah County home, has also counted supplement makers among his top campaign contributors. Two weeks ago, Cannon stopped by Neways’ headquarters to announce legislation that would aid the industry.

At the event, Cannon mentioned he knew people who can’t get by without supplements, and said his brother once worked in a Utah County factory, putting together vitamin capsules.

It’s big business in Utah, he said, one of vital importance that has touched thousands of families, even his. His support is unwavering.

There are two changes to DSHEA most within the industry would support. The first isn’t really a change. From the beginning, DSHEA has asked the FDA to implement quality-control standards, or Good Manufacturing Practices, for the industry as a whole.

“We’re 100 percent behind that,” the UNPA’s Israelsen says. “We’re baffled why the FDA can’t get that done.”

The second is adverse-reporting legislation, which would require supplement makers to report adverse side-effects to the FDA.

“We think it would be a good thing. We have nothing to hide,” says Neways’ Evans. “If our products had problems, we’d be hearing from our distributors, and we’re not.”

“The reason herbs have stood the test of time is because they work. The industry gets criticized from time to time, we think unfairly. Every industry has its detractors. But we’ve been around for 20 years, and we’re not about to fold anytime soon.”

In the end, Evans and Israelsen say they are giving Americans exactly what they want.

Just ask Terrell Owens.

Enjoying Art in the Garden

Alexandra Community Arts Council Art in the Garden project two weekends ago had the benefit of brilliant weather to showcase five exceptional gardens as settings for the visual and musical artistry of almost 60 (mostly) Central artists and performers.
For two days, patrons could drift at will through the gardens from 10am to 4pm, sit in beautiful surroundings listening to high quality entertainment and inspect, discuss and purchase original art in many media, direct from its creators.
All this for a $15 entry ticket.
Organisers expect to clear $8000 this year, with some of that money going towards the councils annual arts scholarships.
Some former scholarship holders like violinist Jenny Banks, home from her studies in Boston, were part of the programme.
While organisers were happy with their best-ever attendance of 560, its an event deserving to be even better known on the annual garden circuit, especially since its timing on the first weekend of the new year fits so nicely in the holiday period.
This years gardens included three adjoining properties on Bridge Hill, making for especially relaxed rambling, another magical small central urban spot, and the large woodland garden at Lye Bow. All already had their own interesting well-established features by way of garden art, as well as accommodating the works of participating artists.
Displays were tucked away from the blazing sun at every turn under umbrellas, on verandas, under trees and in garages.
Works ranged from ceramics to textiles, paintings to photography, recycled glass and metal, and were not confined to pieces suitable for outdoor display, though many were.
Music formed a continual backdrop, though some patrons chose to make it the main event and sat for hours listening to the likes of Queenstown pianist and blues singer Mark Wilson.
Participating painter Marg Hamilton said Art in the Garden provided a wonderful opportunity for artists to have their work seen by large numbers of people and, since prices did not have to include a gallery commission, they could be relatively affordable. (The arts council not only doesnt charge commission on sales, it even pays artists small amounts for expenses for their two days attendance.) Mrs Hamiltons garden was one of the Bridge Hill venues, all quite new gardens offering many ideas for working a dry hillside, making use of distinctive natural rock features, and of the superb outlook.
Just one example from her garden, both striking and practical, is the vibrant and varied shelter hedge around a small lawn directly in front of the Hamilton home, made up of the red rugosa roses, the grey-foliaged Teucrium fruticans, lavender and rosemary, backed by red-stemmed cornus.
It provides both privacy and shelter, without obstructing the view, and year-round colour, so important in a dry climate.
Watch for Art in the Garden 2009. Tickets will be on sale before Christmas and make excellent Christmas gifts.

Desert Landscaping Makes Lovely Show With Little Water

Forget about your Wily E. Coyote image of the desert: all flat, brown, and barren except for a few foreboding cacti. Like any other landscape, the desert hosts perfectly adapted plants and flowers. And to save water while growing low-maintenance plants, it is worth considering bring desert landscaping practices into your home garden. You do not need to turn your whole yard into Arizona, but you will certainly enjoy at least one xeriscaped bed.

Xeriscape What?

Desert landscaping is also known as xeriscape: the art of growing plants that need very little water.

Desert landscaping is first a very responsible environmental choice. Plenty of places have an overall wet climate but experience stretches of drought. When all the neighbors are scrambling to water between watering bans, you will be enjoying your xeriscaped yard without using water. The water that the county has been treated for drinking by humans can be saved for humans.

In a dry climate, plants grow very slowly. While this means your desert landscaping may need some filler for the first few years, after a while it will fill your spot very well. Some xeriscapers even mulch with pebbles or lava rocks rather than mulch. The plants do not need humus, and the rocks last pretty much forever. Patterns of different colored rocks become part of the decoration.

Plant Recommendations

Cacti are what we most associate with desert landscaping. They come in sizes from giant saguaro to tiny plants that look like spiky pebbles on the ground. All cacti produce flowers, but some do so only rarely. One species, native to the United States, produces lots of large, delicate yellow blooms in summer. Called the prickly pear for the pear-shaped fruits that form after flowering, this plant can grow two or three feet tall with a similar size spread.

There are also plenty of non-cactus plants that do well in a xeriscaped bed. Periwinkles and heather grow large and lush in dry places. Lantana is not quite a desert plant, but it needs so little water that it can go with the cacti. Visit your local botanical garden to see what grows well in their xeriscaping section. You will probably see aloes, yuccas, and plenty of other plants that are suited well for your climate.

Unless you live near an actual desert, it may be difficult to buy desert landscaping plants locally. Check the internet and plant catalogs for species to grow.

Rain gardens on the Plains

Alarmed at the volume of stormwater entering Christchurch’s rivers, Beckenham residents Mike and Briar Thorley are taking action.

The couple, who have a young daughter, bought their first home a year ago and plan to incorporate a rain garden in the property’s landscaping.

Most of the rain that falls in the city %26#150; on buildings, roads, drives and other hard surfaces %26#150; is channelled into stormwater drains, which discharge into the rivers. Such stormwater systems are costly to maintain, says Mike, but of greater consequence is their detrimental effect on the rivers.

“Rivers such as the Heathcote are spring- fed, and would naturally have a constant flow of water. Having a sudden influx of stormwater after a downpour places a lot of stress on the river.

“Stormwater rips the banks apart. It has a huge impact on the ecology of the rivers. Sediment is a real problem.

“Water clarity is important for fish, for their hunting. Invertebrates get smothered. They like a stony bottom, which the Avon and Heathcote rivers would have once had. Stormwater also flushes contaminants into the river,” he says.

The idea of a rain garden, whether it be

a whole garden or part of a garden, is to minimise the volume of water entering the stormwater system and maximise the amount of rain entering the soil.

The conventional practice in Christchurch is for rain falling on roofs to be channelled into the stormwater system. In a property with a rain garden, roofwater can be collected in a tank and used to irrigate the garden. It may also be fed into the house for non-potable uses, such as washing and use in the toilet, or it may be fed into the heart of a rain garden %26#150; typically a pond or stream-shaped depression.

In a conventional garden, rain falling on impermeable surfaces, such as driveways, usually ends up in the stormwater system.

In a rain garden, this water is channelled around the garden, usually into a depression in the middle of a planted area, as the Thorleys envisage.

“I’m still trying to work out how to do it,” says Mike. “What size tank do I need? I think I can do it with a 3000-litre tank. How big does the rain garden need to be to take the excess runoff?

“I need to test the soaking capacity of the soil. The subsoil is most critical. It depends on the area in which you live.”

After the heavy rains last year, water ponded on his back lawn, he says.

“I thought I’d have to dig trenches, but after 12 hours, it soaked in.” Indeed, in standard rain-garden practice, water can pond for up to 24 hours before percolation is complete.

In some cases, depending on the subsoil, the land may be excavated up to one metre deep and backfilled with porous material such as a 60, 20, 20 mix of sand, compost and topsoil. Some form of plug and channelling is usually included to let excess water drain into the stormwater system.

Landscape architect Keith Riley says rain gardens take many forms, but the underlying principle is to let each drop of rainwater enter the ground as close as possible to where it falls.

He cites a design he did for a Papanui garden which incorporates a stony- bottomed creek, leading in and out of a rill (a narrow, shallow channel).

This rain garden has water when it rains or when stormwater collected from the roof in a rain barrel or tank is released, either through an overflow pipe or when a tap is turned on. Water stored in the tank is also used to irrigate the garden through conventional means.

Water that does not infiltrate the ground through the porous material that lines the rill and creek is channelled to irrigate plants along the margin of the creek at the bottom of the garden.

Similarly, to maximise the amount of rain entering the soil, the adjacent terraces and patio are made of pervious compressed and crushed limestone, which allows the water to percolate through to the soil below.

The plants most suited to such ponds and shallow creeks are those that tolerate wet and dry conditions. Keith suggests native sedges, rushes and flaxes. A dense covering of plants is recommended to maximise evapotranspiration.

Rain harvesting and rain gardens make sense in Christchurch’s dry climate, he says.

Not only do they alleviate problems of concentrated stormwater entering the city’s rivers, but they use the plants’ and soil’s ability to decontaminate water.

The Christchurch City Council has constructed and is trialling several rain gardens around the city, notably around its libraries in Beckenham and Upper Riccarton and in a long, narrow park traversing several streets in Addington.

While new subdivisions, such as Broken Run in south-west Christchurch, have rain gardens built into them, it is the subdivision rather than individual gardens that has the rain garden collecting road and paving run- off, Mike Thorley says.

He hopes that one day rain gardens will be incorporated into the properties in every new subdivision. In the meantime, he would like other residents of the city to consider fitting the gardens retrospectively.

He also hopes the city council will follow the example of its North Island counterparts and offer guidelines, information and advice. He advises all those who want to learn more about rain gardens and how to construct them to check the internet, especially the Waitakere City Council’s website, waitakere. govt.nz.

Can we still claim the name?

Christchurch is out to spruce up its image as a Garden City, buying up the country%26#39;s biggest garden show. MIKE CREAN looks at the history of the city%26#39;s claims to being a gardening paradise.

Thirty-two businesses are listed in the Christchurch telephone directory under the name Garden City.

Moteliers, pest controllers, wholesalers, they have one thing in common. They seek the feel-good factor of association with the city%26#39;s image as a plant paradise.

It is an image of beds and borders, blooms and bushes, blossoms and branches. But some say it is as faded as a sepia print.

Botanist and former assistant director of the Christchurch Botanic Gardens, Lawrie Metcalf, suggests Dunedin and Auckland have overtaken Christchurch as garden cities. He throws doubt on whether Christchurch ever was a garden city.

It was planned as one, but the vision was lost when the pioneer establishment sold the broad strips of reserve land on the city side of what became Moorhouse, Fitzgerald and Bealey avenues, Metcalf says.

He quotes a former director of parks and reserves, Maurice Barnett, as saying Christchurch was not a garden city, but a city of gardens.

Citizens from early times took pride in their gardens, many seeking to replicate features of the land they left behind, with English trees, shrubs and flowers to soften the landscape. Photographs of Old Christchurch can astonish with the depiction of already mature exotic trees.

Christchurch has borne the label of garden city since 1906, when Sir John Gorst, a special commissioner at the International Exhibition in Hagley Park, coined the phrase. Presumably he was impressed by the appearance of the park, its tree-lined approaches and the nearby Botanic Gardens.

It is not known whether he toured the working-class streets of Sydenham. If he had, he might still have been impressed, as this %26quot;model borough%26quot; consisted of neat cottages with well-ordered vegetable patches behind and tidy flower beds in front. This was the case in most parts of town. It was generally agreed that the plain household gardens of the city of the plains excelled those of other towns.

However, the garden-city image probably owed more to the grand homes of those who had grown wealthy from Canterbury%26#39;s great pastoral runs and could afford to keep expansive woodlands, lawns and shrubberies on large sections in the newly fashionable Fendalton.

These set the standard for all classes. Donald Odering, of the Oderings garden- shop chain, says when people worked set hours and had few cars and limited money, many had little option but to toil in their gardens. They developed pride in them, which became reflected in the establishment of societies fostering gardening through talks, tours and competitions.

People strived to produce the best dahlias and tomatoes. In their favour was Christchurch%26#39;s settled, dry climate and plentiful supply of water, which gave the city an advantage over other towns.

%26quot;And don%26#39;t under-estimate their English descent,%26quot; Odering adds.

Englishness may equate with love of gardens but is also synonymous with self- deprecating humour. A standing joke in the 1950s was that Christchurch was called the garden city because the council was always digging up streets.

Increasing affluence in recent years has changed lifestyles. People have more diverse interests which leave no time for gardening. Metcalf claims a move to hedonism is lowering gardening standards. He also laments subdivision of existing sections, in- fill housing and the erection of high fences around properties.

Odering, though, is optimistic. He says if people are lured by such counter-attractions as boating and skiing, those who continue to keep gardens are truly committed. These keen types ensure Christchurch does well in the gardening stakes. His experience in the company%26#39;s shops around New Zealand is that Christchurch still leads in plant sales.

Former city councillor Carole Anderton is a committed gardener. She knows many people who spend $10,000 a year on plants, fertilisers and gardening items. She says people developing new homes often spend about $40,000 on landscaping, irrigation and plants. She notes a great enthusiasm for gardening and says Christchurch%26#39;s gardens are %26quot;definitely improving%26quot;.

Home gardens may be in good heart, but Christchurch%26#39;s public spaces are not faring so well.

Leafy avenues, graceful river banks, attractive parks and Botanic Gardens that once ranked among the best in the world have long impressed visitors to Christchurch. Anderton says this aspect of the garden image is wilting. Metcalf says the Botanic Gardens were the jewel in the city%26#39;s crown but %26quot;the jewel has lost some of its lustre%26quot; and %26quot;the crown has become somewhat tarnished%26quot;.

Both accuse the city council of failing to provide leadership and funding. They cite the delay in appointing a director of the Botanic Gardens, since the untimely death of David Given two years ago, as an example.

%26quot;If we want to be the garden city, we need to channel more money into it,%26quot; says Anderton. She believes residents would support this and notes the Botanic Gardens attract more visitors than the art gallery but receive less funding.

Her wish list for Christchurch includes a better entrance and new administration buildings for the Botanic Gardens, hanging baskets and large pots of seasonal flowers in and around Cathedral Square and well- planned tree planting on city streets, instead of the current %26quot;mish-mash%26quot; that afflicts much of the cityscape.

So, is Christchurch the garden city?

Odering is positive. Metcalf says it is still a %26quot;very pleasant place to live%26quot; and its garden image is %26quot;recognised widely here and overseas%26quot;. Anderton says Christchurch has %26quot;greened up%26quot; since she moved here 27 years ago but needs changes in public areas to ensure its garden city status.
