How big do Sinningia tubers get, Rick? Achimenes and Eucodonia rhizomes vary wildly in size. I think that's due to age, generally. They make little clumps of tubers all during the growing season. They make them generously though. Even a cutting will make a few rhizomes even when started late in the season. They crumble easily, too, and those crumbles can grow plants. I can't tell the little tuber on your Sinningia is formed of little segments. Are they a solid structure?
