I hope so too! Many, many years ago when I was looking for epiphyllums, I stopped at one nursery and asked about them...the guy actually did not know what they were, but showed me an "orchid cactus". I said, well, that's an epi and I took it. I don't remember how long it was in a pot on the other property, but we've been at this place for 15 years, it's climbed up through a tree and NEVER bloomed. I didn't think that was possible...lol..
There's a place here in town that grows dragon fruit for sale and their website has some impressive pics....
