Walking Lila, our chug, the other evening (I realize I’ve referred to her as a pug in the past, but she is actually a chug) I spied this ground cover. The intent seemed to be for it to take the place of a lawn, and was doing a pretty good job. The bracts look a lot like a Euphorbia. Is this a Euphorbia ground cover variety that I know nothing about? Can anyone ID it? Is it a weed?
