Aquatic Crinum

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!
Ciao

Subject : [pbs] Aquatic Crinum
Hi Gang,
J. Schulze described Crinum thaianum in the early- or mid-1970s (Plant Life,
The Amer. Plant Life Soc. [H. Traub &H. Moldenke, eds.] 27:33-42). He
described it as a completely aquatic, Crinum species from Thailand. Since that time
it has been used as a water plant by aquarium enthusiasts.
He also mentioned three other fully aquatic Crinum species from Africa (2
species) and the Americas (1 species). Crinum natans seems to be another aquatic
Crinum, but I have not sorted out the differences and names yet.
Question: Do these relatives of garden Crinum survive a few days out of
water, or must they be submerged essentially all the time?
Question: Does anyone grow these for flower?
Cordially,
Conroe Joe
