As we speak, the plant is being propagated in vitro at Atlanta Botanical
Gardens in Georgia, I believe. It is not yet available for distribution.
I do not believe anyone in the U.S. is specializing in _Sarracenia_
using in vitro, although the people who do in vitro work in the U.S. are
certainly working on the genus to propagate them, especially the rare
taxa. I could get you their addresses if you wish. The two most active
that I know of are Ron Gagliardo and Bob Hanrahan.
