Here is the vendor list Ken, an interesting assortment. Most are local growers in Western NC and Upstate SC but there are people from Taiwan, Peru, one from CA and Krull Smith from FL. BB Barnes is an Asheville nursery and if you are looking for anything else, they are terrific, I have never noticed that many orchids there though.

I am still vacillating on whether to go or not. There is an outstanding garden festival in Charleston the same weekend. Also, the street paving is now set for April 1 or April 9th and I plan on going to Asheville during that mess. If that gets delayed due to weather, maybe I'll be there.
