ajuga reptans

Creeping Jenny, however, I would not recommend this groundcover unless you have a way of keeping it contained. OH, and once you have it in place, it is very difficult to get rid of. That being said, it is a beautiful groudcover which has it's place............just not in small areas.

Silver Ponyfoot (Dichondra argentea) covers well and spreads quickly. Though not reliably winter hardy in 8a, it does return many years.

Am liking Texas betony (Stachys coccinea) as a long-flowering evergreen cover, but not much experience yet covering large spaces.

Edit: Horseherb spreads well with partial sun, but slow in heavy shade. However, rabbits keep it from working for us. Zexmenia is a decent rabbit-resistant alternative that can work as a groundcover. Both are deciduous in 8a.
