General information

A robust plant that’s a member of the mint/dead nettle family, bugle is an erect, perennial wildflower that forms dense mats and can be seen carpeting damp places in open woodland, grassland and hedgerows. The flowers are similar in appearance to selfheal, they’re from the same family and have similar medicinal properties.

A native to Europe, this herb grows up to 40cm in height, with a basal rosette and long, leafy, rhizomatous runners that spread aggressively and is very invasive, if not kept in check. For theses reasons it’s often used as a ground cover plant as they keep taller brush in check and supress weeds with its thick, dense foliage.

Identification

Flowers: The deep blue – purple (on rare occasions white) flowers are borne on erect, hairy stems and are up to are 15mm long. They are similar in appearance to selfheal and ground ivy.

Leaves: The basal leaves form as a rosette and are ovate to spoon shaped, the upper and stem leaves are un-stalked and borne in opposite pairs. The lower leaves(up to 7cm long) are generally larger than the upper leaves, with all leaves having a smooth, glossy surface and are dark green – purple in colour.

Value for wildlife

This plant is hermaphrodite (contains both male and female organs) and is pollinated by bees, butterflies, hoverflies and moths. See infographic below.

Bugle: Frequently Asked Questions

Is bugle invasive or a good ground cover?

Bugle is not considered invasive, but it is an aggressive, fast-spreading ground cover. It propagates via creeping above-ground runners (stolons) that root as they touch the soil, quickly forming a dense carpet. This makes it an excellent, low-maintenance weed-suppressing ground cover for shady or damp spots where grass struggles to grow.

How do you propagate bugle?

Bugle is remarkably easy to propagate. Because it naturally sends out runners, you can simply lift and divide these rooted sections in spring or autumn and replant them elsewhere in the garden. It can also be grown from seed.

Can you walk on bugle grass?

While bugle can tolerate occasional light foot traffic, it is not a true lawn substitute for heavy use. Frequent walking can crush the succulent stems and flower spikes, though it recovers reasonably well compared to more delicate perennials.

Can bugle grow in full shade?

Yes, bugle is exceptionally shade-tolerant and naturally grows under the canopy of deciduous woodlands. While it adapts well to partial shade and even some morning sun (provided the soil stays moist), deep shade will not stop it from growing, though it may produce slightly fewer flowers.

What companion plants go well with bugle?

Because bugle makes a dense, low-growing carpet with contrasting foliage and blue flower spikes, it pairs wonderfully with taller woodland or shade-loving perennials. Great companions include hostas, ferns, spring bulbs (like daffodils and bluebells), lily of the valley, and Japanese forest grass.
