I can almost hear my friends in wetter parts of America groaning! Pinellias! Panayoti! You have GOT to be kidding...these are ineradicable weeds for many of you I know. That's punishment for living where gentle rains soak your landscape on a more or less regular basis...for those of us who live on the godforsaken steppes of America (they're simply awful--stay where you are) we can grow these things just fine. They are even a tad, well, picky (we have to put them in shade, in places we actually commit to watering. If not...bye bye! The one above is Pinellia pedatisecta, which I enjoyed finding on top of Confucius grave. Quite literally...in Qufu, Shandong province to be exact. I do have it seeding here and there--just enough to share with friends. It is green flowered, like most pinellias--if you do not like green flowers, have a good long chat with your therapist and get over it.
This is public enemy number one: Pinellia ternata...it has the famous bulbils in the axils of the leaves which (along with real seeds) are responsible for its bad habits. In Colorado it doesn't seem to be a problem. Here it is in Sandy Snyder's wonderful garden. I must remind myself to ask her for a piece so I can traumatize wetlanders when they visit me...it's green too!
