Bletilla striata, when you can find them, are incredibly expensive but they grow like weeds. That 3 x 3 pot probably holds one bulb. Go figure. I dug up enough to fill my trunk and brought them back to Reno to give away to my Orchid Society friends. They were thrilled because all had researched the prices.
I just purchased Bletilla ochracea and am intending to plant it outside in a warm spot. According to Plant Delights, they are hardy to zone 7a. I'll let you know how this goes.
I have Dactylorhiza purpurea and Epipactus gigantea growing in my yard also.
