T. grandiflorum is an eastern US plant.  We have been growing it
successfully (it comes back) in our Eastern N. America collection at the UC
Botanical Garden. It has not spread extensively as it does in habitat. On
the other hand, our T. chloropetalum and albidum (not easy to distinguish)
have thrived in our native California collection, especially under oaks. As
Ben Anderson mentioned earlier, it gets minimal supplemental water. I've
started lots from seed but don't find it easy to raise them to maturity;
takes many years.
