I just saw this thread, and noticed that there weren't any other posts, so I thought I'd add one. The Longwood Gardens show is somewhere near Pittsburgh, I belive, but not sure. The plants in the photo, and the display in the background are all by the Native Orchid Conference. One member grew the plants and forced them. No, forcing does not hurt the plants. For all those interested in North American native orchids, the N.O.C. is an excellent organization to be involved with.
