Looking for Blue Curls and Rhexia

I don't know if I'll find anyone with these to trade (let alone for SASE), but if you have some, please e-mail me. Or if you know of a source to purchase them, that would be great too. Botanical name for Blue Curls is Trichostema dichotomum. The Rhexia has several species in the genus, and I'd prefer mariana, unless there's one that is better acclimated to the mid-South.

Did a search and this is what I came up with. The last one you can buy the plant from. The other 2 im not sure...
Hope this helps.
