Yet another pereskiopsis request

Hello everyone, I have become very interested recently in not only pereskiopsis but pereskia also, if anyone knows where I am able to get some I would greatly appreciate it as I haven't had much luck. I was also looking for some hylocereus cuttings, I am very interested in not only their grafting capabilities but also their fruit, the same goes for pereskia. (and pereskiopsis but I was reading somewhere about it not fruiting? Obviously because of the amount of times it has been cut. If someone could clarify that would be great.)

Cheers!
