Hey, I'm looking for some rare U.S. eastern species like:

Sedum Pulchellum

Diamorpha (Sedum) smallii

Rhodiola (Sedum) rosea (eastern form preferred - but I'll take a western)

Golden Heather (Hudsonia - any species)

Minuartia carolina

Saxifraga michauxii

Or other interesting native eastern alpine, sand barren or rock plants. I've got lots of bog plants, orchids, native sedums and other rare native plants I'd be willing to trade.
