This plant has been on my want list for a while now but I haven't had any luck locating seeds (or a plant/cuttings). Firstly, can anyone point me in the right direction for a source?

Also, how is viability with these seeds? I assume that, because they're tropical, viability is short and germination rates may be disappointing. If this is the case, should I just look for someone with cuttings and wait to propagate my own seeds when the plant matures and fruits?

Thanks!
