Winterberry Gardens (Spoons) is by mail. You could probably shoot them an email with your list. That is how I found out that Dan Laing isn't available this year. I emailed and Ginny Spoon responded that they had sold too many, and needed to grow more stock. It is on my most wanted list for next year!!
Dewuc is at several vendors I believe. I know Napa Iris still has it for this year. They also have Kickapoo Kangaroo, Bewilderbeast and Chocolate Moose.
Blue J Iris carries quite a few Kaspereks too. I think that is where I saw Giraffe kneehiz and Hog Dogs and Mustard.
