Hi Joe and all, I grow thaianum and calimistratum (a var. of natans). They are completely submerged all time. In summer I put them into a little pond at full sun, in winter (I live in zone 8) I put them in an aquarium with temperature at 18-20°C. I have not seen the flower till now, but I hope to. There is little in literature about these items and less in horticulture. I am experimenting!
