thanks! Just looking up ground covers, and I found this for edible suggestions:
"For fruiting ground cover, try planting a mix of lingonberries, strawberries, American cranberry, Creeping Oregon grape (tart but edible) and wintergreen. With the wintergreen you can use both the leaves and the berries that appear during the winter.
If you want to stick with herbs your best bets are sage, mint, oregano, chamomile and thyme. All of these grow low to the ground and are good spreaders."
So maybe mint is a good option?
