Genus Ajuga (Bugleweed)

ah-JEW-gah Common Name: Bugleweed

The genus Ajuga includes annuals and (usually) rhizomatous perennials in 40 species that come from shady habitats in temperate Europe and Asia. Some are grown for their colorful foliage. Most have blue, 2-lipped, tubular flowers in whorls in spring to early summer. Bugleweeds make great groundcovers, especially in moist conditions. They spread from rhizomes or stolons.
Noteworthy characteristics: Attractive foliage; tubular, 2-lipped flowers in whorls. Excellent groundcovers, but A. reptans can invade lawns.
Care: Ajuga needs a moist soil in partial shade (their foliage may scorch in full sun). Some species tolerate poor soils and full shade.
Propagation: In early summer, separate rooted stems or take root cuttings.
Problems: Southern blight is very common, while various fungal leaf spots, crown rot, and fungal root rot can also occur.

Black foliage and spiky blue flowers (which appear in early summer) make a dramatic contrast. 'Black Scallop' thrives in full sun, which intensifies the black color. In full sun, the plant produces numerous runners, which should be thinned to prevent crown rot. In large plantings, you can run a rotary mower with a bagger attachment over the patch to control crowding and keep the foliage fresh. In mixed container plantings, the spilling habit of the plant makes it a standout choice.
