AJUGA reptans

Carpet bugleweed is a low growing evergreen perennial 15cm tall which forms a dense matlike groundcover as it spreads along underground stolons. As is typical of herbaceous plants in the mint family, bugleweed has square stems and opposite or whorled leaves. The basal leaves are dark green and oblong. The flowers (usually blue or purplish) are about 1.3 cm long and borne in whorls on erect spikes 15.2cm tall. Many cultivars have been selected for foliage or flower color.
