There's no better source than Rob's mini-o-lets for the small ones. You can order direct from the violetbarn online. They also have a lot of images to look at leaves and flowers.

Lyndon Lyons has some very nice minis also

Thanks everyone! I think I have AF fever!

I've bought many times from Robs their really great, and their packing and shipping are outstanding, never even had a broken leaf. Lyndon Lyons is great to, but i never mail ordered from them. Visited both under the guise of a business trip, really first class operations.
