thanks Sky. I take it you're just using regular potting soil? I germinated them just fine on moist filter paper in petri dishes in our incubator (lower light and cooler temps than our growth rooms). I transplanted them super small with tweezers to our soil-sand mix thinking it would give them a leg up on moisture but the clevelandii and the other quad I tried hated it and just failed to thrive in the growth room. =/ Also, a lot of the species capsules shatter as soon as they ripen. megalosiphon and suaveolens both made like little goblets, but thankfully they weren't sticky at all. I checked them every day, gently plucked off the "cup", dumped the seed in an envelope and just threw out the capsule. the quad buds appear to have a lot of trichomes so I bet they're going to be a sticky mess...
Wallace, all I can say is I haven't grown Amplexicaulis yet. The only species I've grown so far are Suaveolens, Megalosiphon, Noctiflora and Undulata (neither of which were very successful), Paniculata, Africana, Sylvestris, Tomentosiformis, the Quadrivalvis and Plumbaginifolia im currently growing, and rusticas of course. however, I can say that some of the Suaveolentes group from Australia (to which amplexicaulis is a member) can be quite difficult im told (but so are benthamiana, suaveolens and megalosiphon and they grow quite well). its a total crap shoot. let me know how it goes.
