For the unusual vegetable enthusiast, the place to find seed are the alpine garden clubs’ seed exchanges: Scottish Rock Garden Club (SRGC), Alpine Garden Society (AGS) and the North American Rock Garden Society (NARGS) are the main international ones and each puts out a seed list of several thousand varieties donated by the members…by no means just alpine garden plants! I remember reading an article in the North American Herb Companion with a recommendation to source seed of unusual herbs from NARGS.
My SRGC seed arrived today  and here they are, a mixed bunch including the yellow form of Kamchatka Lily (Fritillaria camschatensis “Aurea”), one I’ve been looking for for some time! You can probably read some of the names but there are Phyteumas, Ligularias, Alliums, Dahlias, Lilium, Polygonum macrophyllum, Agastache, Zanthoxylum simulans and Boehmeria…
