How to Identify

A creeping perennial plant. It grows 30 cm high and spreads to 60 cm across. It has stolons or runners. The plant forms roots as it spreads. The leaves are opposite and dark green. The flowers are blue to purple. They occur on short spikes.

How to Grow

Prefers a humus-rich, moisture retentive soil and partial shade. Does well in marshy soil and in the spring meadow. Grows well in dry shade and is fairly drought tolerant once established, though it shows distress in severe drought. Plants do not always ripen their seeds in Britain, they spread freely by runners, however, and soon form an extensive patch in suitable conditions. A number of forms have been selected for their ornamental value, several of them are variegated and these are used especially as ground cover plants for dry shade. A purple-leafed form, 'Atropurpurea' does well in full sun so long as the soil is not dry. A good bee and butterfly plant. Heat Zone: 9-1.

Propagation: Seed can be sown in spring or autumn in a cold frame. Germination usually takes 3–4 weeks at 10°C, though it can be erratic. Prick out seedlings when large enough to handle and plant them out during summer. Division of runners can be done at almost any time of year and is very easy — divisions can be planted directly into their permanent positions if needed.

Medicinal Uses

Bugle has a long history as a wound herb and, though little used today, is still considered valuable for arresting haemorrhages and treating coughs and spitting of blood in incipient consumption. The plant contains digitalis-like substances — the type commonly found in Digitalis species and used in treating heart complaints — and is thought to have heart tonic properties. It has also been considered useful for countering excessive alcohol intake. The whole plant is aromatic, astringent, and bitter, and is usually applied externally. It is harvested as it comes into flower in late spring and dried for later use, though it is also commonly used fresh in ointments and medicated oils. A homeopathic remedy is prepared from the whole plant. It is widely used in preparations for throat irritations, particularly in the treatment of mouth ulcers.

Other Uses

Bugle makes a good ground cover in semi-shaded positions, forming a carpet and rooting as it spreads. It is fairly fast-growing but does not always smother weeds and can become bare at the centre if conditions are poor. It is also used as a perennial ground cover for zone 2 firebreaks in the US government's system of fire management zones surrounding buildings, where low-growing plants provide minimal fuel.

Ajuga reptans is commonly known as bugle, blue bugle, bugleherb, bugleweed, carpetweed, carpet bugleweed, carpet bugle, and common bugle, and traditionally (although less commonly) as St. Lawrence plant. It is an herbaceous flowering plant in the mint family Lamiaceae, native to Europe. It is also a component of purple moor grass and rush pastures, a Biodiversity Action Plan habitat in the United Kingdom. Ajuga reptans is a dense spreading groundcover with dark green leaves with purple highlights. The leaves grow 5–8 cm (2.0–3.1 in) tall. In spring the plant sends up 10–15 cm (3.9–5.9 in) tall flower stalks bearing many purple flowers. The flowers are frequently visited by flies, such as Rhingia campestris.
