Bugle is a perennial herb that can spread by seed or, more typically, by means of creeping stems known as 'stolons' or 'runners' (3). It flowers from late April to early July (6). The flowers are pollinated by bees, although self-fertilisation is also possible (2).  Bugle was, in the past, a well-known medicinal herb. It was used mainly to treat wounds, and was once widely planted in gardens to provide a ready supply (5).
