Green Community everdale: a tbg green partner

Thanks to a new partnership with Everdale Organic Farm & Environmental Learning Centre, the TBG was able to launch an exciting new series of workshops focusing on sustainable and ecologically friendly construction projects. The third workshop in the series takes place on Saturday, March 28,

From The ediTor

Awhen landscape architect Janna Levitt and Terry McGlade, owner of Gardens in the Sky, will show you how to create a green roof or roof garden on new and existing buildings. 10 a.m. to 4 p.m. Public $85, members $80. Pre-registration is required: 416-397-1341 or torontobotanicalgarden.ca.

With our new spring issue, Trellis blossoms into full colour

s eagerly as gardeners await the start of a new season, the Trellis Committee has anticipated the launch of this fresh new look of Trellis . Long recognized as the benefit most valued by TBG members, with many articles written by volunteer garden writers, Trellis has served us well for more than 15 years. But just as the TBG has grown and expanded, so Trellis must evolve to better reflect our revitalized organization.

This new full-colour magazine features the same authoritative content, but with enhancements that present the information in more engaging ways. For example, TBG News highlights special events, staff appointments, volunteer achievements and outreach activities while In Season provides timely gardening advice from TBG gardeners and the Master Gardeners.

With all these changes, we haven’t forgotten our commitment to the environment. Trellis is printed with vegetablebased inks on recycled paper and soon will be enclosed in a biodegradable plastic bag when mailed with special inserts. Nor have we forgotten our fiscal responsibilities. A solid business plan forms the foundation of Trellis magazine, making this important member benefit more self-sustainable.

But the new look of Trellis would not have been possible without the contributions of several important groups and individuals. Thanks go to our very creative art director, June Anderson, for an exciting new design; to the talented members of the Trellis Committee who contributed the ideas for our new format; and to the Toronto Master Gardeners whose generous donation made our dream of a dynamic new Trellis come true. Thank you all for your passion and commitment.

TheHIgH-IMPACT Low-Care

Garden

In these excerpts from her latest book, Tracy diSabato-Aust discusses impressive plants for low-maintenance gardens.

HIGH-IMPACT TRAITS

• Multiseason interest

• Colorful foliage

• Long-lasting bloom

• Outstanding texture

• Architectural form

LOW-CARE TRAITS

• Long-lived — a life span of five or more years

• Tolerant of heat and humidity

• Cold-hardy

• Deer-resistant

• Resistant to insects and disease

• Requires minimal or no deadheading

• Prospers without heavy fertilizing

• Doesn’t require staking

• Infrequent or no division required for four or more years

• Infrequent or no pruning required to maintain decent habit, appearance, or best flowering

• Non-invasive

• Drought-tolerant

I’m constantly rethinking areas of my garden and seeking beautiful yet tough plants to replace demanding ones. I refer to them affectionately as indomitable – not easily defeated, resolute, unconquerable, determined, and strong. These plants should not only be easy to care for but they should bring passion and excitement into our lives with their colors, textures, shapes, and scents. It’s great if a plant is easy to grow, but if it’s of minimal ornamental value, who really cares? With plants, like all things in our lives, we want to have our cake and eat it too. We want beautiful, wonderful things but we don’t want to devote countless hours to them because we don’t have countless hours.

What makes a plant high impact? It should make a statement in multiple seasons because of its long-lasting bloom, its color, texture, form, or even fragrance. Better yet, it should possess all or most of these characteristics. On top of that it would be nice if it was somewhat theatrical and had a flair for the dramatic.

So, first and foremost, a plant considered high-impact needs to provide interest in several if not all seasons. For example, a multiseason plant may have beautiful flowers in the spring followed by foliage that has an interesting texture in the summer

and then goes out with a bang of gorgeous autumn color.

Color can be provided by longlasting flowers, or by striking foliage, bark, or fruit. Several plants have been selected [for this book] because of their yellow foliage. Yellow is a dominant color, acting like a magnet for the eyes – think about the draw of a candle flame. Many plants have been chosen for their interesting and unusual texture or for their architectural forms, which create living art in the garden. If we rely on plants in our gardens that provide a demanding architectural presence and outstanding texture and foliage, we can keep the integrity of the design together without as much care as if we rely on plants that solely provide fleeting flowers.

All right, so it’s not enough for a plant just to be dynamic – it must also be easy to grow. I like to choose my battles when it comes to maintenance, so I consider the specific chores a plant requires. For example, I’m more tolerant of plants that need pruning to look their best than I am of ones that demand frequent division or can be affected by pests. You should consider what does and does not work for you.

Sowing

Goodness

Jack

staub takes us down the not-so-straight path to creating a beautiful vegetable garden.

We all know that growing at least some of what we eat or, at minimum, purchasing our produce from local farm sources will result in fresher, healthier, better food on our tables. But the goodness derived from these simple acts goes far beyond that easy equation. Keeping an edible garden or purchasing locally is not only good for you, it’s also good for your local farm economy and, most importantly, vital to the survival of our planet.

The writer Michael Pollan estimates that “the way we feed ourselves … accounts for about a fifth of the greenhouse gas for which each of us is responsible”. And the fossil fuel loads necessary to keep the food chain in motion are considerable. For instance, transporting a single calorie’s worth of fruits or vegetables from

California to New York consumes eighty-seven calories’ worth of energy. It also costs three energy calories for every calorie of processed and packaged food produced. Weigh that against the miracle of spending $1.50 on a packet of seeds and cultivating a season’s worth of lettuce or tomatoes, which costs our earth nothing and, in fact, re-nourishes it.

However, the idea of keeping an edible garden seems to be a stumbling block for even the most avid decorative gardeners. I believe this stems from that age-old vision of legions of vegetables grown in rows, sprouting from endless acres of soil, back-breakingly tilled by mule and plough. Erase that un-pretty labour-intensive picture from your mind. Instead, conjure up the artful symmetry of intimate plots of raised beds arranged in patterns and planted with a pleasing mixture of herbs, vegetables, fruit trees and flowers. Consider creating this type of garden an exercise in decorative, multiple parterre planting within a fenced or walled space. When you do, the doors open to a more pleasurable experience: a garden that’s more beautiful and easier to work in.

Early gardeners, from the Aztecs at Tenochtitlan and the Egyptians to the earliest Swiss and Roman settlements, found that a bed raised even a scant 15 centimetres (six inches) above ground level provided infinitely better

drainage than one situated on the soil surface – and it heated up faster in the spring too. Also, beds built no broader than 1.2 to 1.5 metres (four or five feet) across and separated by paths made it easier to reach into the middle to do chores such as weeding and watering. Another advantage the ancients discovered was that working with feet planted on a nice clean path instead of in the vegetable garden meant the soil didn’t get compacted or the plants crushed underfoot.

Design your potager just as you would a decorative border or flowerbed. Before selecting what to grow in your potager, think about what you like to eat. There are literally thousands of different vegetables from all corners of the globe. They come in every shape, colour and flavour imaginable. Then, consider plant height and texture, leaf form and foliage colour. Also consider juxtaposing contrasting characteristics and using vegetables with beautiful flowers.

There is no right mix, and every year provides a new opportunity to test an award-winning new cultivar or try another combination. And each year offers another chance to discover the incredible goodness that can result from so simple and rewarding an endeavour. For surely, if you plant, we will all of us reap.

Jack Staub is a leading expert on edible plants and vegetable garden design. He has written frequently for leading gardening publications and is the author of 75 Exciting Vegetables for Your Garden, 75 Remarkable Fruits for Your Garden and 75 Exceptional Herbs for Your Garden. His gardens at Hortulus Farm Nursery and Gardens in Pennsylvania have been featured in many publications.

Anna’s Plant Pick

trumpet Gentian Gentiana acaulis Group

True blue flowers are favourites in most gardens. The Gentiana acaulis Group features plump, upright, blue trumpet flowers that smother mounds of foliage in springtime. Members of the group include the species G. acaulis, alpina, clusii, dinarica, ligustica and occidentalis.

For best results, grow these alpines in fertile welldrained soil in full sun or only a little bit of shade. Locations that allow water to run away from the crown of the plant, such as the top of a low wall or a mounded rock garden, help prevent rot and make good spots from which to admire these natives of European alps. Unlike many rock garden plants, which generally do well in lean soils, gentians benefit from a richer mix; so add some compost to the planting hole. Many people will tell you how easy it is to grow gentians; however, if your plant doesn’t flower, try moving it – even only a metre away can make a difference. Also, plants may decline after several years. When this happens, dig them up and divide them in the early spring, then replant in soil amended with compost.

Enjoy the blues!
