For me, this plant grows too well. I wanted a groundcover for front of flower garden. This was a bad idea. This plant spread to every plant within 5 feet the first year, and into the grass as well. I pulled and dug out from other plants for another year and gave up. Dug up all ajuga and sprayed what was in the yard. Birds evidently love it, because I have found new plants in yard 100 feet away from original site. This would be a great plant for steep slope by road, for erosion control.

I love this plant and use it in several places around the yard. A well behaved groundcover, ajuga spreads slowly but fills in empty spaces very completely. Not hard to pull out if it starts getting out of bounds. Beautiful flowers, and no pests bother it that I've seen. Likes to be moist and does better for me (zone 9) with partial shade, but survives in full sun with adequate water.
