Wild Flowers of Pittsburgh

Bugles (Ajuga reptans)

Also called Bugleweed, a name it shares with Lycopus virginicus. This is a popular groundcover at garden centers, usually in varieties with bronze or variegated leaves. The original green-leaved version is thoroughly naturalized here; it persists in old plantings for decades, but it also pops up on its own, especially at the edge of an open woodland. The flowers are normally blue, but there is an uncommon lavender form, as we see in this stand in Beechview.

Calyx 5-toothed. The large and spreading lower lip of the corolla with the middle lobe emarginate or 2-cleft. Stamens as in Teucrium, but anther- cells less confluent. (From a- privative, and xygon, Latin jugum, yoke, from the seeming absence of a yoke-fellow to the lower lip of the corolla.)

A. reptans L. Perennial, 1-2.5 dm. high, smooth or but slightly pubescent, with copious creeping stolons; leaves obovate or spatulate, sometimes sinuate, the cauline sessile, the floral approximate, subtending several sessile blue flowers. Locally in fields, Me. and Que. to s. N. V. May-July. (Nat. from Eu.)
