Yep, they are getting pretty common really....shouldn't be too difficult to replace. I'd suggest pot culture, but leave them potted when they have their very short dormancy....best of luck, but you'll be able to replace these much more easily than some of the rare species so that is a positive in all of this :o) Dan

I do believe Troy has seeds on his site now. I think he calls it sumatra flora of something.
