Sinningia tubiflora grows and flowers well in a large pot here in the low desert in full heat and full sun all day. It is not harmed in the least by full sun with temperatures to 118 F / 48C. It needs plenty of water when in leaf. I've heard from many people who have reported trouble flowering it in smaller containers, or in other than full sun. Often I can't convince people to try a larger pot, plus full sun. I haven't tried it in the ground because my soil isn't soil, its fist-sized rocks separated by dust. I don't want to put it into a raised bed for fear of it taking over. Of interest, years ago Alberto Castillo in Argentina wrote to me that the species forms a solitary tuber in habitat. This has not been my experience, nor that of others. Here it forms very numerous tubers almost to the size of small hen's eggs. Leo Martin Phoenix, Arizona, USA Zone 9?
