There are several companies that list heirloom potatoes but I happen to think that the best of the best is Ronniger's and I've linked to it below.

I don't know of a list specifically on heirlooms, but below is a page with a lot of links. Go about 1/3 of the way down the page to the section, "Varieties & Breeding".

mister,

Interesting link but quite a few years out of date since it doesn't even list Google as an internet research tool and it refers to Ronnigers as Irish Eyes, which was a bad merger that occurred many years ago and Ronnigers has been back as Ronniger's for several years now.

I thought the poster was loking for a commercial place to buy seed potatoes where the varieties are described in detail.

At no one place would one find a listing of ALL the known heirloom potato varieties and that includes SSE which has a tremendous number listed and the Ronnigers have been the major players in that regard, along with Will Bonsall of Canada, who is the SSE Curator for potatoes.

I basically wanted to find names and descriptions of different heirlooms. Once I find a few varieties suitable for my area I would try to find a Canadian source.
I did find a bit of information from the Agriculture Canada website (Potato Research Centre) and of course, Seeds of Diversity.

Eagle Creek Seed Potatoes has purchased the mail-order portion of Becker's Seed Potatoes. Their mail address is Box 70, Bowden AB T0M 0K0. Their website is listed below; by and large the majority of varieties listed are modern ones.

Thanks for the tips everyone!

Ronniger's may be a more practical list, but if you want comprehensive try the International Potato Center in Lima. Pretty neat.

Do not know, if they ship to US but you could look at the Irish Seed Savers Site.
