I know Jalan Kayu has already given out D.intermedia seeds, but I have some (soon) which I can also give out.
This species, I'm told, is from Cuba, so requires no dormancy. Also, the leaves turn red in full sunlight. Well, some, at least.
Pls PM me with ur address if u'd like the seeds. The seed pods haven't ripen yet, but if all goes well, I should have them soon.
