Any retail center that pots their own product would buy from Walters, most likely. They are the number one wholesaler of plugs in the nation. Some retail centers only buy the already potted plants, such as the ones from Monrovia, though.
I don't grow Ashva, but I saw on Brushwood's site that they offer it, if you are interested in ordering. I think Silver Star has it also, but not certain.
Thanks, I already decided I like it, and have a flat coming, along with Isago and Veronica's Choice. And a few others I hope to get, Shimmer, Diamantina, and Pistachio, which will probably sell out before I get my order.
