Ajuga reptans is known as bugle, blue bugle, bugleherb, bugleweed, carpetweed, carpet bugleweed, and common bugle, and traditionally but less commonly as St. Lawrence plant. It is an herbaceous flowering plant, in the mint family, native to Europe.
Ajuga reptans, commonly called bugleweed, is a dense, rapidly spreading, mat-forming ground cover which features shiny, dark green leaves. Whorls of tiny, blue-violet flowers appear in mid to late spring on spikes rising above the foliage to 10". Cultivars of this species feature leaves with more interesting and varied foliage color. When in full flower, large clumps of bugleweed can produce a striking display. Dense foliage will choke out weeds. Not particularly tolerant of foot traffic. Genus name origin is unclear. Specific epithet means creeping.
