Hitch Lyman at Temple Nursery PO Box 591, Trumansburg, NY 14886 has by far the biggest selection of snowdrops in this country (but even he hasn't recently listed Wendy's Gold, that I recall). He does have Lady Elphinstone (a yellow double), which multiplies like crazy for me. I suppose you could write him and ask if he has in his collection and would sell you a WG. His catalog, as I recall is $3.
