Bert - I highly recommend Texas Waterlilies. They do mail-order and usually sell out of their Lotus, so if you decide to order from them, order early before they are all gone.

Cubits has offered a co-op every year from this nursery and did have one last year. Texas Waterlilies used to sell the plants to us wholesale. I got some awesome water plants that way for a really good deal! You could try contacting Mamajack to see if she is going to do a co-op from them for 2014.
