Edible Garden Newsletter April 2019

From Ottawa Carleton & Lanark County MGs

TEG April 2019

The Edible Garden Newsletter April 2019 is now available. This month, we feature a very rarely grown legume to our part of the world--Peanuts. It is doubtful that Peanuts will become a cash crop in Eastern Ontario but for those who like a challenge, it is possible to grow them here and even harvest a few. Swiss Chard is native to Southern Europe and will tolerate heat but it grows best in our cooler climate. It is not a demanding vegetable and some think it is almost "too pretty to eat". Our author has also provided information on some of her favourite varieties. Carrots are another popular vegetable. While they sometimes seem fussy to start, they grow well here and are one of the root vegetables that are easy to store and in the right conditions can last most of the winter. We even include a recipe for an easy to make and delicious Carrot Cake. Finally we start a new series on Soil, focusing on the terms we use to describe it.

Canada's National Flower - Bunchberry

national flower winnner

The votes are in! Canadians have spoken!

A nation-wide contest to celebrate Canada’s 150th anniversary, sponsored by Master Gardeners of Ontario, has embraced the bunchberry, known as quatre–temps in French and kawiscowimin in Cree, as the winner.

Since the beginning of the National Flower Contest, the little white flower has held the lead with an average of 80 per cent of the on-line vote. Since it was announced in March, almost 10,000 Canadians took up the challenge to help select our national flower.

Master Gardeners of Ontario will submit an online petition to Parliament to have the winner declared Canada’s official National Flower, says Maureen Hulbert who spearheaded the project: "We all love to celebrate the wildness of Canada and its varied areas and having something that can actually grow in every part of the country pulls us together".
