I do have a Ylindropuntia Whipplei – Cholla Cactus Bonsai tree is very beautiful but very prickly if you not careful. I have added two videos of a man and woman encountering a Cholla cactus. The man is just down right stupid and the woman is trying to warn people about the cactus. She does a really great job to! Check out the Cholla Cactus Bonsai page for more information. I repeat please do not kiss a Cholla Cactus or walk through a bunch of them!
