They are not in TC that I know of. A few seedlings were released as well as some larger plants floating around from cuttings. Propagating from cuttings is excruciating slow.
I am working on some cuttings from the few seedlings I have. I opted to just get a few seedlings rather than invest alot on a bunch of seedlings that would have had a $$$ pricetag (Trent was pretty darn close on his estimate).
