Sorry (Not Sorry ;)
Taylor Greenhouse of NY sells rooted cuttings in 2.5 inch pots for about the same as single cuttings from most internet sellers. The first two plants I ordered from there were nice enough that when one I really wanted came back in stock I ordered 5 more. The current list with descriptions from the internet... for what they're worth.

There are a few variants of this species so some blooms can be slightly different one variant to another.
