I'm putting my kids to sleep for the winter. This year, I grew them in a four-inch top-layer of long-fiber sphagnum moss. The good: the rhizomes expanded DRAMATICALLY making lots of babies. The bad: I already have hundreds of Sarrs and am out of room.
I have lots of extra tarnok, regular leucos, S. rubras that I know are endangered but aren't sure of the species (thanks to squirrel label predation), oreos, and others that I would be willing to share with someone who will care for them. I live in northwest Ohio, so you'd have to be willing to pick them up.
