I have taken a cutting from a large cactus, and it seems to propagate well. I was wondering what species it is? Does anyone know? Thank you in advance.
I think that's a Euphorbia, not a cactus. Similar to E. grandicornis. The tell is that the thorns aren't coming from an areole, they're growing from the edge of the plant.
All cactus are succulents, not all succulents are cactus.
Hopefully, a Euphorbia expert will chime in with an ID.
