ground cover with foot traffic
I'm looking for suggestions for a suitable groundcover for around a small tree in the middle of the hell strip in front of my house. It will be in full sun and will have to tolerate moderate foot traffic. Since it will be trapped between the street and the sidewalk, spreading/invasiveness would actually be fine. Scent would be a plus. Ajuga is what immediately comes to mind, but others must have other ideas. Creeping thyme? Something else? Thanks.
