Hello Jim: I have never grow it. I prefer the geophyte which is radial symmetry from top. (Both leaves and flower.) But there are discussions about it in several forums of of plant in Taiwan. The native bulbs which I had grown are Lilium and Lycoris, and some aroids. (I also have try the gingers and banana family but most of them them should not be native to Taiwan.) The Formosa lilies are easy to get virus, and get strange line flower pedals. And the speciosum and lycoris does not perform well in my house. They may more adapt to the North east winter rain and cool area of Taiwan. (They seems to bloom not reliably in the middle and south of Taiwan lower-lands where winter is dry and warm even hot. But perform better in the field and where are less buildings. Maybe for the cooler night temperature.) Some of the native aroids are not suitable to my house, while 1 do propagating but do have a dormancy in a 1 year interval in my house. Fierycloud,Taiwan.
