Every year we re-create an index of the garden vegetable varieties available from seed companies in Canada. The complete list is available for free on our web site at https://seeds.ca/sources and at https://seeds.ca/seedfinder
Besides offering a useful Canada-wide seed finding service for gardeners, our catalogue index has an important purpose: it helps us know which varieties are in the greatest need of rescue, back-up, and rejuvenation by seed savers.
Also, with records going back over 20 years, we can see trends in commercial availability of every vegetable crop in Canada. This really helps all of us to understand food diversity and seed security.
