Plants typically reach about 50 cm (20 inches) in height, with a spread of about a metre (40 inches).

Used as ground covering around shrubs or in places where it is difficult for grass to grow, the bugleweed is a great option to bring in some colour. Its purple leaves look fantastic when grown beneath trees.

It is commonly seen planted along pathways as well.

In mid to late spring, blue lavender flowers begin to bloom and can stand up to 25 cm (10 inches) above the foliage.

The small flowers attract pollinators such as bees and butterflies, which are always an added benefit for any garden.

Gardener's HQ Guide to Growing Dark Purple Bugle

Growing Ajuga reptans Atropurpurea is very simple. It can grow in many soil types as long as there is adequate drainage.

Ensure your placement for planting is far from foot traffic so this mat-forming plant can grow, spread and thrive.

It is a fast-growing plant so if it becomes too crowded or is larger than desired, it can easily be divided in spring or autumn.

This plant needs full sun to part shade, and at least 3-4 hours in full sunlight per day for best results.

Although it can survive in mostly shaded gardens but the colouring will not be as bright and vivid IN these conditions the leaves may remain greenish instead of turning purplish.

It prefers soil of medium moisture so it will require frequent watering in hot and dry climates.

In the winter, the foliage will hold its colour and will not die back. The leaves are very hardy and can withstand lower temperatures.
