I see you're new here, welcome. Pls. do some reading around here on mixes. While it's good that you're already using Cactus & Succulent mix (C&S for short), you will quickly see that many if not most of us here have learned to amend our C&S mixes (w/perlite or pumice, at least 30% or 50% to be safest), 'cause these days, commercial mixes have too much peat in them (kills out plants) &/or include wetting agents to retain water (also kills our plants). Others of us on here use mixes you'll see mentioned as Gritty Mix or variations of 5:1:1, things like that, which over time folks have learned worked well for them. Also some of these pre-made mixes contain fertilizer as well, which many of us wish to control ourselves rather than someone unfamiliar w/ our growing conditions. There are lots of opinions on mixes, but key & accepted by all of us is that to grow C&S, we need fast draining mix & what you've pictured above doesn't look like that. So that's an improvement that could be made easily & help the plants more that almost anything else one could try.

a lady brought it to me at the greenhouse, said she was tired of taking care of it. I love it, but don't know what it is. it's easy to take care of though! it's in a hanging basket now and it's starting to trail over the side.

I tried to edit before, but it disappeared. Several sources I tried to post indicate seed-only propagation. I'm not going to find the links again. But UF says division is possible & it is a more reputable source, so I'll go with that. I don't think I've ever seen a pup, but I'll keep an eye out now that I'm curious. In any event, they are endangered, largely because they are slow growing & difficult to germinate. That results in widespread and illegal harvesting here in Mexico. That part isn't subject to refutation.

Outside Don't let it loose in your garden or beds Full sun Water as needed and use a soil that drains well. It's a genetically vigorous plant that doesn't like to be too wet or too dry. 4 kinds of mint from cuttings ^^^. If you keep them pinched, you can keep them looking tidy - not known as a well-behaved plant. Al
