Ajuga reptans


The deep blue flower spikes of Bugle can be found carpeting damp grasslands, scrub and woodland clearings scrub and grassland on fertile soils. Spreading by means of overground runners that frequently root, it flowers between April and July and is attractive to a variety of insects including White-tailed Bumblebees, Green-veined White Butterflies, Silver Y Moths and Common Carder Bees.

How to identify

Low-growing and creeping, Bugle has larger, oval leaves spread out in a rosette at its base and smaller leaves that grow up its flower spike; small purple flowers sprout in between the leaves. The flowers are shaped like skirted ladies, often with faint stripes running down them and with protruding stamen poking out over the top.
