Crinum thaianum

Crinum calamistratum is very similar in habit and requirements (IME it's
smaller, but only a bit), but has narrower leaves with very tightly
crenulated margins. Sort of a more "aristocratic " version of thaianum.
Better specialty aquarium outlets should stock it. I've grown it in
CO2-dosed aquaria, and it is spectacular.
best regards,
Dave

Dear Alani and all,
This is an excellent posting and full of real practical experience.
Foliage up to 12 ft long . Wow.
It does seem that the high light level needed for good growth is
enough to fry buds and flowers that develop in this heat.
It seems very likely that bulbs offered in these retail pet stores
are nursery grown - they are fairly uniform in size and cheap and numerous.
I imagine they sell for pennies in Thailand before they get packaged and
imported to the sales racks.
Seems like they would rapidly out grow most home aquaria, too.
Again thanks for all this info. Still absorbing it.
Best Jim W.

I have grown Crinum thaianum for about 20 years in aquaria and during the
summer in various ponds and water gardens. It will grown in fairly
shallow
water water but really prefers some depth.........the foliage which can
easily get up to 9-12 ft long or more.
I have switched to a T5
HO florescent fixture with four bulbs.
. I have also been growing the African aquatic species
Crinum calamistratum and Crinum natans which have beautifully undulated
foliage and grow in the same conditions as Crinum thaianum.
