What species is this old friend?

Post by Stilwell »

New to the forum. Not a cacti expert.
Years ago, I came upon a cactus on the curb at our local recycling center. It obviously had been neglected and was in bad shape, but was large at the base, although only a foot high; it had been topped. I took it home. With minimal attention, it grew like a weed. I have rooted cuttings many times, given plants away, and usually have five or six plants ranging from one to seven feet on hand.
Recently, it occurred to me that I had no idea what species it is. After hours of online research, l can only say that it looks like an Echinopsis.
So can someone help me with the ID? Also, I have never had one bloom. Is it that they don't get full sun for much of the day, or that I have to bring them indoors in our winter (central North Carolina, USA). Really appreciate any help you can give me.

Cereus repandus may be a more acceptable name.

In some opinons - others think Cereus hildmannianus. These are plants that have been in cultivation for a long time, no one knows what the original source was, and they've more than likely been randomly crossbred. Cereus peruvianus is not a scientifically valid name, but it's the name they're commonly sold under.
