Hard to say. Sedum? Maybe.

i have some of that in my garden..like a sedum..IDK the name, but i take cuttings, put in cup of water , it roots fast and plant in another spot..looks good on my rock wall bed.

I have this as well, indoors. My guess is Jobs tears or baby tears - pilea. Job's tears is probably what I have as it can handle drying out. Baby tears I think needs more water.

Mine is quite hardy and tolerates a lot of light and water conditions but seems to love bright indirect light and dry surface between waterings the best. It propagates and roots easily.

Hope that helps!
