I took a trip down to Dundas, Ontario to visit William Dam Seeds, one of the oldest seed companies in Ontario. I read somewhere that William Dam seeds has been selling only untreated seeds since the owner got sick some 40-50 years ago. Inspired by a new encyclopedia that I picked up featuring vegetables, edible flowers, herbs and fruit, I bought a bunch of edible flower seeds and planted them in the greenhouse the next day.
