My grandmother started a cutting in a small pot 25 years ago. She was under the impression that it would only get one bloom a year. And that's what it did... for a while. My grandparents would stay up nights waiting for the flower to open. Since then, the cactus has grown in a wild fashion and spread along the block wall, engulfing anything and everything. We have had to cut it back several times, because its natural habit is to reach for the trees. It began to take over the bottlebrush tree that can be seen in the photo. The original pot has turned over and very little dirt is left, so it likely gets most of its nutrients from the air, and roots that have attached to the wall. It wasn't until 5 or 6 years ago that it started to have multiple blooms throughout the year. It seems the older the plant gets the more blooms it produces. So much for the "single bloom a year" assumption! The other night I counted 18. The red "Dragon Fruit" in the photos have resulted from natural pollination of the flower. But I have decided to do it by hand with the hope of yielding more fruit. I've attached a couple pictures of the dragon fruit. They remind me of a kiwi, but taste more like a melon.
Sorry for the length of my post. Thank you for all of your responses.
