@TexChik I got just one part off a cactus of a friend 10 years ago in Indiana. I have had it inside the whole time. I water it once every two weeks. The top part came on about 4 years ago. The base of this cactus is wild and thick.
@Echoing there are some nasty ones out here. The cow crippler... which you hate to step on ... and the “ dog Turd cactus “ that you just can’t get off of you ! Lots of Opuntia ( prickly pear ) as well
