Hi I Love to collect different varieties of Thanksgiving & Christmas cactus. The old fashion and rare varieties are hard to find. Sometimes I have found some at Garage & estate sales! I find it's hard to find. The Garden centers don't know much about growing these cactus! if people are interested in a local trade and growers group? You can leave a response here: for example: city and zip! And if you want together at a place or online?
