Plant delights mailorder nursery has it, it's the only place I've seen carrying it so far. I've been thinking of trying it too. This is a very reliable nursery if you're thinking of ordering it.

Thanks, Davissue, for the link. Its a little more than I wanted to pay, but since none of my local nurseries seem interested in getting it for me I think I'm going to go ahead and splurge! I saw it in the Proven Winners catalog but I don't think I can order directly from them.
