hi norman, this particular species will take full sun in its native habitat (Espirito Santo state, in southeastern brazil). i sent seed to the PBS, and the tuber you are getting might be a descendant of my plant. Sinningias for the most part are not true terrestrial plants, but grow in forest litter on rocks (lithophytes) or sometimes on trees (epiphytes). the soil mix as described by dylan is a good recipe. do not treat it as a cactus, it needs a richer substrate. both my plants go dormant every year around winter time. one of my tubers bloomed just this past month; the 2nd one just started putting out new growth last week. i have them in a south window in my apt. but even that is not enough light for them. they really like to be baked in full sun. watering of course should be kept up during this growing period. although i'll say, if your tuber is a small one, it might need some protection from full sun. it'll probably be hardy in CA, but it should be protected from frost of course. hope this helps. tsuh yang --- Dylan Hannon <othonna@gmail.com> wrote: > Norman, > A simple peat + perlite mix with a little sand > (10-15%) works well > with sinningias in general.
