Description

Ajuga pyramidalis is a perennial plant from the Lamiaceae (mint family).  It is ground cover with year-round interest that forms by spreading from short rhizomes up to 12 inches.  The pale blue-violet, spiked inflorescence blooms May to June.  The flowers may be mowed or weedwacked off when blooms are finished to help enhance the foliage appearance.   Mass plant it in a border front, foundation plant, entryway,  container, or use it as an edging or in a rock garden. Propagate it by removing daughter plants or by crown division.  The stems are rooted shallowly in the first year of growth and are easily removed but if left to grow it can spread into surrounding planting beds and lawns and become quite dense and difficult to move.  This plant is resistant to browsing by deer and rabbits and can be planted near black walnut trees.

In Latin Ajuga means as "without yoke and reptans means "creeping", which refers to the plant's spreading runners.

Insects, Diseases, and Other Plant Problems:  Crown rot in very wet conditions or dieback under prolonged extremely dry conditions.  It slowly invades other planting sites through its rooting runners.
