I am fairly new to Gasterias, and I am interested in obtaining a few more. Seed would also be interesting.
For trade I can offer some Gasteria bicolor liliputana which throws out an occasional varigated plant. I have lots of Daylily seed I hybridized myself this past summer, or a pretty good variety of Bromeliad pups, mostly Neoregelias with colorful foliage but a few from other genera as well.
I can send a list of the Brom pups with photos, and if you can tell me what color Daylilys you might be interested in I can probably find some nice seed for you.
