groundcover between stones

I'd like suggestions for a fairly flat-growing groundcover to plant between large flagstones that cut a path through a mixed border. I currently have Ajuga in there - it looks great but is an obstacle. You have to step over all the mounds. I also goofed and interplanted it with the wrong kind of thyme; it's about 6" tall and is taking over. The planting looks nice, but is difficult to walk through/around.

I'm looking for something fairly flat and tight-growing that will just fill in between stones and be fairly easy to control in the neighboring beds. I don't care if it flowers or not. The exposure is mostly sun and I'm in Zone 9. I hope someone out there can suggest a couple of candidates. I'm taking out the Ajuga and thyme asap. Thanks and happy autumn.
