plant sellers?

[FountainMan]

I've begun an indoor water garden similar to a multi chamber shallow fish tank. One of the chambers is used as a plant filter in addition to being decorative. Anyways, I purchased some oxygenators from Petsmart and cut some of the overgrown marginal plants from the pond. But now I'm looking for plants that float and have floating leaves like frog bit, Azolla, duckweed, water clover and am wanting Dallas-For Worth suppliers.

I usually buy from Water Gardens Galore in Dallas but was informed that they're renovating and won't be open this year.

Does anyone know of a retailer of live aquatic plants in the Dallas, TX area?

Thanks.
