The portulaca I pictured never reseeds. I was referring to the regular old variety of portulaca from 50 years ago that reseeded everywhere.
The one I pictured is bigger than the common variety. I wonder if it is some kind of hybrid. Or maybe the perennial kind mentioned a while back in this thread. When I root it, I just stick some in potting soil in a pot, but keep it inside or under shade since we normally have very low humidity.
Although, it can't be lower than Phoenix.
