2010 Symposium on Sustainable Horticulture
What part does horticulture play in making urban Canada a healthy, productive place to live?
How does our urban landscape - gardens, parks, lawns, ecologically designed hardscapes, green roofs and other innovations - ensure that well-being and biodiversity are supported and enhanced?
What steps can all practitioners of horticulture - from the trades to home gardeners and plant breeders - take to issues like invasive species, pest management and urban biodiversity?
The symposium will explore these and many other questions, Wednesday February 17th through Friday February 19th, 2010 (with a day of workshops on Tuesday February 16th).
- Hands-on workshops one day only, Tuesday, February 16: plant identification, seed saving, cooking with local produce
- Multidisciplinary panels, keynotes, presentations and poster sessions
- Sessions: Sustainable Sites Initiative, water features, climate change, urban agriculture, native plants, green roof technologies and more
- Keynote presentations: Dr. Jennifer Sumner, Ontario Institute for Studies in Education, University of Toronto, Dr. David Galbraith, Royal Botanical Gardens, and Dr. Steve Windhager, Lady Bird Johnson Wildflower Center, Austin, Texas

Floriography
Elizabeth Washington Gamble Wirt, 1784-1857
Originally published in Baltimore by Fielding Lucas, June 1829.
This first dictionary of flower meanings can be viewed in full (scanned version) (or downloaded to your Kindle) thanks to the contribution from the University of California Libraries to the Internet Archive.
My appreciation grows for these scanned copies of treasured books for the sake availability and record, but oh how I'd appreciate even more being able to hold an original copy.
Ms Wirt's floral dictionary was one of a number published during the Victorian Age; when gardening for leisure flourished, and propriety meant constraint, the symbolic use of flowers was a means of expression. Floriography, or the meaning of flowers, has continued to serve as a instrument of the romantic gesture. What I adore about Flora's Dictionary is the combination of science and folklore. The book begins by setting the stage for a botanist's study, but the references aren't direct and are quoted from literature, namely poetry - the songs of the heart.
Often the message is as much about the colour of the flower as the flower itself. Over time, the language of these emblems of emotion has been reconstructed; for instance Ms Wirt's yellow Tulip symbolized hopeless love, while now is commonly known to speak for cheerfulness. Innocent Daisies stand over time, but the Foxglove Digitalis evolves from "a wish" according to Flora's Dictionary to being known as "dead man's bells" or "witches gloves" due to the potency of the plant's chemicals.
Whatever their meaning, flower symbolism continues to satisfy the human psyche, and the heart. With Valentine's Day quickly approaching I'm quite certain the florists will be busy interpreting the language of flowers.

six more weeks
Wiarton Willie saw his shadow this morning, and so we have six more weeks of winter. Shubenacadie Sam, and Punxsutawney Phil did, and I'm going to assume our furry little friends R.O.U.S.'s in the LU Garden have also seen their shadows.
This means six more weeks of winter reading, so I picked up a copy of The God of Small Things today from the university bookstore. Winner of the Booker Prize, I was sold by the description of being "lush and lyrical", and the first chapter title: PARADISE PICKLES & PRESERVES.
Roy begins with a description of Ayemenem, India in May; rich in red ripening bananas, and fruity air - just the sort of place I want to read myself into on this cold February. A little bit of travel writing to take me some place else.
Groundhogs are popping up all over the city, not only in the LU Garden. The courthouse on Court Street also boasts a groundhog, and I'm sure there are some living near the ridge of Hillcrest Park - near our garden. Luckily Claire and Gromit have little affection for large rodents, and will do well at keeping them at a distance. woof
The legend of the groundhog's forecasting powers, though up for discussion, dates back to the early days of Christianity in Europe when clear skies on the holiday Candlemas Day, celebrated on Feb. 2, meant an extended winter.
The tradition founds its way to Germany, altering so that that if the sun made an appearance on Candlemas, a hedgehog would cast its shadow, thus predicting six more weeks of cold weather.
The Groundhog Day was then carried on in North America during the late 1800s thanks to a Pennsylvanian newspaper editor and publisher, who organized and popularized a yearly festival in Punxsutawney, Pennsylvania. The festival featured a groundhog named Punxsutawney Phil to foretell how long the winter would last.
A typical groundhog, or by its scientific name Marmota monax, weighs approximately 9.5 pounds with a body length reaching about 20 inches.
Groundhogs use their short, powerful legs, claws, and large teeth to dig underground living habitats, which can run quite extensively with as many as five entrances and various tunnels extending some 45 feet, and as deep underground as 5 feet.

"Shubenacadie Sam, Nova Scotia's furry season forecaster, spots his shadow as he emerges from his enclosure in Shubenacadie, N.S. on Monday, Feb. 2, 2009."

FRESH
FRESH celebrates the farmers, thinkers and business people across America who are re-inventing our food system. Each has witnessed the rapid transformation of our agriculture into an industrial model, and confronted the consequences: food contamination, environmental pollution, depletion of natural resources, and morbid obesity. Forging healthier, sustainable alternatives, they offer a practical vision for a future of our food and our planet.
Among several main characters, FRESH features urban farmer and activist, Will Allen, the recipient of MacArthur’s 2008 Genius Award; sustainable farmer and entrepreneur, Joel Salatin, made famous by Michael Pollan’s book, The Omnivore’s Dilemma; and supermarket owner, David Ball, challenging our Wal-Mart dominated economy.
Establishing A Food Forest
Educator and Consultant Geoff Lawton discusses the principles of Permaculture and Agroforestry in his film on developing sustainable, ecological food systems. A review of the film can be read here, I can't describe it any better. Though the film features in Australia, the principles are globally relevant.
Consider how this theorum can be applied in our Boreal forest.

OMAFRA factsheets
Why Farm Organically?
Factsheets from the Ministry of Agriculture, Food & Rural Affairs are a invaluable source of information. Though focused on commercial farming, the principles can be applied to any grower. The OMAFRA Vegetable Production Information page lists everything from soil science to seed companies, and homemade pesticides from Health Canada.
Season Extension Techniques for Vegetable Crops is a particularly relevant sheet to gardeners in our area.
Interim Report on Ontario's Biodiversity (a 66 page pdf document from the Ontario Biodiversity Council) discusses everything from native species, ecosystem diversity, sustainable use and Integrating Biodiversity Conservation into Land-Use Planning. The anecdotal (though fundamentally scientific) information in the document and links to further reading can keep a gardener well entertained on a rainy spring day.
The Ministry of Natural Resources extends to Ontario’s Biodiversity Strategy and "seeks to engage more Ontarians in our efforts to achieve the goals of protecting biodiversity and ensuring the sustainable use of our biological assets."

Vermicomposting
Pictured right is Marge Stadey of the Ogden-Simpson Veggie Garden Project showing some children her worm compost at the local food forum at the Lakehead University Agora in November 2008.
The Thunder Bay Vermicomposting Network was initiated by Dr. Brad Wilson and a number of his students of the Geography Department at Lakehead University.
Worm composting is an efficient way to deal with home kitchen food scraps, turning it into useful and nutrient rich compost for your garden. The process is simple; instructions can be found here, compiled by EcoSuperior.
Red worms (red wigglers) are the companions you want for your worm composting, and are available from Dr. Wilson's network.
City Farmer executive director Michael Levenston's posts in City Farmer News are some of my favourite to read. I've been subscribing to this journal for a long time, and am continually engaged with his historical Canadian gardening stories, along side the current movements City Farmer News follows on the west coast.
In a recent post, City Farmer News published the following video on worm composting which answers a lot of the questions people have, and with this video demonstrate the process.

more cold day dreaming
Frosty Day
Robert Frost ~ A Girl's Garden
A neighbor of mine in the village
Likes to tell how one spring
When she was a girl on the farm, she did
A childlike thing.
One day she asked her father
To give her a garden plot
To plant and tend and reap herself,
And he said, "Why not?"
In casting about for a corner
He thought of an idle bit
Of walled-off ground where a shop had stood,
And he said, "Just it."
And he said, "That ought to make you
An ideal one-girl farm,
And give you a chance to put some strength
On your slim-jim arm."
It was not enough of a garden,
Her father said, to plough;
So she had to work it all by hand,
But she don't mind now.
She wheeled the dung in the wheelbarrow
Along a stretch of road;
But she always ran away and left
Her not-nice load.
And hid from anyone passing.
And then she begged the seed.
She says she thinks she planted one
Of all things but weed.
A hill each of potatoes,
Radishes, lettuce, peas,
Tomatoes, beets, beans, pumpkins, corn,
And even fruit trees
And yes, she has long mistrusted
That a cider apple tree
In bearing there to-day is hers,
Or at least may be.
Her crop was a miscellany
When all was said and done,
A little bit of everything,
A great deal of none.
Now when she sees in the village
How village things go,
Just when it seems to come in right,
She says, "I know!
It's as when I was a farmer--"
Oh, never by way of advice!
And she never sins by telling the tale
To the same person twice.

Batty Bats
- A single insectivorous bat can eat hundreds of insects an hour, including mosquitoes and agricultural pests, reducing our dependence on pesticides.
- Frugivorous bats in the tropics are vital in seed dispersal and nectivorous bats pollinate plants when they feed on nectar.
- Although 70 percent of bats eat insects, many tropical species feed exclusively on fruit or nectar.
Despite their notoriety, vampire bats make up only a small portion of all bats (there are only three species), and they live only in Latin America. With the exception of three species of nectar-feeding bats that live along the Mexican border of Arizona and Texas, all bats in the United States and Canada are insectivorous.
- Fruit bats bring us over 450 commercial products, including 80 medicines.
- The seed dispersal and pollination activities of fruit and nectar eating bats are vital to the survival of rain forests.
- Seeds dropped by tropical bats account for up to 95% of forest re-growth on cleared land.
Bats are such unique mammals that they have been placed in a group of their own, the Chiroptera, which means hand-wing. Bats are of the grand order, Archonta, grouped together with monkeys and flying lemurs. All living bat species fit into one of two major groups, the Microchiroptera or the Megachiroptera.
Linnaeus was so impressed by the similarities between bats and primates (lemurs, monkeys, apes, and humans) that he originally put them into the same taxonomic group.
Most agree that bats are far more closely related to primates than to the rodents with which they often are linked in the public mind.
- Only three out of more than 1,100 species of bats worldwide feed on blood, and they are all in Latin America.
- As for spreading rabies, BCI states that fewer than half of one percent of bats contract rabies, and rabid bats usually are not aggressive.
Guano is the collective term used for bat or bird droppings or feces. For many years, people all over the world have been using guano to fertilize their crops.

Basil
Botanical: Ocymum basilium (LINN.)
Family:
N.O. Labiatae
Belonging to the Lamiaceae (formerly Labiatae) (mint) family, Basil in our region is an annual plant, with broad leaves ranging from green to purple, depending on the cultivar, with flowers range from white to lavender.
Preferring a sunny location with at least six hours of bright light per day, Basil thrives in moist, well drained soil. It is quite sensitive to dry conditions, so it is important to watch it closely during hot weather.
Basil self-sows by producing many dark brown seeds in the many small florets.
The word Basil is derived from the Greek basileus, meaning "king," although to the ancient Greeks and Romans the herb was a symbol of malice and lunacy. They believed that to successfully grow basil, one had to yell and curse angrily while sowing the seeds. In French, semer le basilic, "sowing basil," means ranting. (source unknown)
- Basil attracts bees and is usually considered for a garden for honey bees.
- Basil has traditionally been given as a good-luck present to new homeowners.
For transplanting, start basil seeds indoors in small pots in mid-to-late April (bottom heat helps), moving plants outside when the temperature is warm (late May or June) or sow the seeds directly outdoors once all danger of frost is past.
Planting Out
As basil is frost sensitive, set plants outside after no risk (in the last few years here in Thunder Bay that has been late June, sometimes even early July). Transplanted seedlings need to be hardened off before planting out.
Basil needs real warmth and regular fertilization. A manure rich soil, I find, grows the largest leaves. Worm and compost tea, and cold coffee in my office seems to keep my basil plants happy.
Space basil 30cm (12") apart in full-sun.
Companion Plants
Pepper, Tomato, Marigold
When planted next to tomato plants, it wards of the white fly, which plagues the tomatoes.
There are more than 50 species of Ocimum and more than 60 varieties of Ocimum basilicum. A selection of basils, from Rodale's Illustrated Encyclopedia of Herbs, is as follows:
Ocimum basilicum / Sweet Basil
Ocimum americanum (tender perennial) / Lemon Basil
O. basilicum 'Anise' / Anise Basil
O. b. 'Cinnamon' / Cinnamon Basil
O. b. 'Crispum' / Lettuce-leaf Basil
O. b. 'Green Ruffles' / Green Ruffles Basil
O. b. 'Minimum' (tender perennial) / Bush Basil
O. b. 'Nano Compatto Vero' (tender perennial)
O. b. 'Piccolo Verde Fino'
O. b. 'Purple Ruffles' / Purple Ruffle Basil
O. b. 'Purpurascens' / Dark Opal Basil
Diseases & Pests
Diseases to watch for are Botrytis cinerea, Black spot, Damping off, Fursarium wilt.
Fusarium wilt of basil, first identified in the early 1990s, arrived via infected seed imported from Italy. Symptoms include sudden wilting and leaf drop, accompanied by dark streaks on the stems, usually in weather above 80°F. If you notice these signs, quickly dig up the infected plant, along with all soil around the roots, and discard it. Avoid spreading the disease by moving soil around on your tools or tiller.(source unknown)
Basil is also susceptible to a few bacterial rots that show up on stems or leaf clusters, usually in cool, wet weather, often late in the season (or in our case, June). Keys to control include planting in well-drained soil, spacing plants so they dry off after rain, and removing infected plants from the patch.
Medicinal Uses / Homeopathy:
It's many medicinal uses include for bad breath, constipation, vomiting, stomach cramps, whooping cough, wounds, bites.
- A teaspoon of dried basil leaves in 1 cup of boiled water is said to relieve cramps, vomiting, constipation and headaches caused by nerves.
- Basil tea is considered so calming, that it is used for upset stomach, spasms and in particular whooping cough.
- In massage oil it is a nerve tonic and helps to ease sore muscles.
- According to some, basil oil in a diffuser will relieve mental fatigue.
- Fresh leaves can be rubbed on the skin as an insect repellent, or chewed as a mouthwash. (It is a mint after all.)
Culinary Basil
Although identified readily with Mediterranean cuisine and Italian pesto, basil is a native of India where it is regarded as a sacred herb dedicated to the gods Vishnu and Krishna. Some species of basil will grow as perennials in the south Asian regions.
Basil is a very versatile herb with a variety of possible uses. It is excellent in tomato-based dishes, spinach, and all types of squash. It is great in soups and stews, but don’t add it until the last thirty minutes of cooking. Cooking alters the herb’s flavour and tends to make the minty side of basil come to the forefront.
It can also be used on sandwiches, dips, and pasta dishes. Basil is very important in Thai, Laotian, and Vietnamese cooking.
The later in the day you harvest basil, the longer it stays fresh. In a perforated bag kept at around 60°F, it will keep for 10 to 14 days. In contrast, refrigerated basil only lasts two or three days. You can also store stems in a vase in your kitchen, close at hand for cooking.
Tear basil rather than chop with a knife because when you chop the oil stays in the leaf and does not properly flavour your food.
Basil is best fresh, but can be preserved by drying or by freezing. To do this, tear the leaves into small pieces and freeze small batches of them in ice cube trays with a little bit of water. Once frozen, the cubes can be saved in zip-lock bags and can preserve the fresh flavour of basil for up to four months.
Of the countless species of basil the favourite in the kitchen is Sweet Basil (Ocimum basilicum), with its close relative Genovese Basil being preferred for making pesto. Also, the lemon basils with their citrus tang, are excellent for desserts, soups, tea, lemonade and for cooking with fish and chicken.
1 cup fresh basil leaves chopped
2 tbsp pine nuts or walnuts
1 clove garlic
1/2 tsp salt
2 tbsp grated parmesan cheese
2 tbsp grated romano cheese
1/2 cup olive oil
1 lb egg or plain noodles
Sauce: puree all ingredients except the oil and pasta. Add the oil slowly until the sauce is creamy. Prepare the noodles. Drain and add the sauce.
Greek Summer Salad
3 to 4 tomatoes
1 cucumber
1/2 cup olive oil
1 tbsp lemon juice
1-1/2 tbsp vinegar
2 cloves chopped garlic
3 tbsp fresh oregano
1 tbsp fresh basil
1 tsp salt 1/2 cup feta cheese
1 head of lettuce olives (optional)
Cut up tomatoes and cucumbers and put in a large bowl. Mix olive oil, lemon juice, vinegar, garlic, oregano, basil and salt together and pour over vegetables. Refrigerate. At serving time, add lettuce, torn to bite size, and cheese crumbled into small chunks. Olives optional.
*Baked, Grilled or Barbecued Vegetables
*Add several fresh basil leaves to slices of zucchini, onions and tomatoes and bake, grill or barbecue until done.
To best maintain the flavor of dried basil, store it in the freezer. To quick-freeze basil, dry whole sprigs and pack them in plastic bags with the air pressed out. To dry basil, pinch leaves off the stem and spread them out in a shady, well-ventilated area. Check in 3 or 4 days, and if they don’t crumble easily between your fingers, finish drying in the oven; otherwise the leaves may turn brown or black in storage. Use the lowest heat possible with the door slightly open, turn leaves for even drying, and check them frequently.
Another method is to make pesto (or even basil processed with olive oil), pack it into containers or ice cube trays, and freeze it. Once cubes are frozen, you can pop them out of trays and into plastic bags for easy storage.
*Opal Basil has dark, purplish leaves and is particularly good in herb vinegars and dressings.
3 tbsp. Extra virgin olive oil
1 large onion, diced
4 garlic cloves
2 bunches fresh spinach leaves, washed & with stems removed
1 cup fresh basil leaves
3 cups herb or vegetable bouillon
1 cup milk (or milk substitute)
Dash cayenne
Pinch of freshly grated nutmeg
¼ cup freshly grated Romano cheese
As a member of the mint family, basil is sometimes recommended as a digestive aid. Try an after dinner cup of basil tea.
