Gardeners' Notes:


On Sep 16, 2015, outdoorlover from Enid, OK (Zone 7a) wrote:

Pretty and durable ground cover. I have it growing in about 3-4 hours of morning sun. I planted it this past spring so have not propagated it yet. Its leaves are fatter and rounder than the 'Chocolate Chip' ajuga.

Hardy and beautiful groundcover...grows well in full shade, half shade and can even take an hour or two of brutal Texas sun...forms a dense mat and is very drought tolerant while 'showing off' that beautiful black scalloped edging on the foliage.

Planted two in shade in 2011. Neither one survived a fairly mild winter. Would not recommend.
