Our Canadian Seed Finder (www.seeds.ca/seedfinder) shows all the garden vegetable seeds offered from 120 Canadian seed companies in 2025. This year, there are a whopping 9636 varieties available - that’s a lot of selection!
You can use it to find your favourite seeds (we encourage you to give it a try!), but at Seeds of Diversity we use it for another reason… to learn which seed varieties are easy to find, and which we need to rescue!
Seeds of Diversity's member seed growers plant hundreds of different kinds of seeds every year, and save them to preserve the varieties - so gardeners can keep growing rare heirlooms next year, and for many more years after that. But it doesn't make sense for us to save varieties that are easy to buy.
Here are the top 26 least-rare vegetable varieties, in order of how many seed companies sell them. We know for sure that there's no need for seed savers to rescue these ones!

This is the very reason why Seeds of Diversity exists. Almost two thirds of all commercially available vegetable varieties are only offered from single sources, each from just one company out of 120. Those are the varieties that seed savers should grow and exchange, because they can disappear forever so easily. Many of the seeds in our Seed Library are those that fall into this category, as well as many more that can’t be found through seed companies at all. In fact, 2046 of the 3036 varieties in our seed collection aren’t available commercially in Canada - that’s 67.4%.
An annual membership to Seeds of Diversity gives you access to our seed exchange, seed grow-out programs, and our online news.
