dark purple bugle


Ajuga reptans 'Atropurpurea', commonly known as Carpet Bugle, is a perennial plant that is prized for its attractive foliage and blossoms. Its leaves are perhaps the most striking feature, having a rich, deep purplish-bronze color. These leaves are typically oval to spoon-shaped and appear in a rosette formation, hugging close to the ground and creating a dense mat that effectively suppresses weeds. During the blooming season, Carpet Bugle produces flower spikes that rise just above the foliage. The flowers themselves are small, tubular, and generally a deep blue or violet hue, adding a splash of vibrant color to the garden. The combination of the dark foliage and the blue flowers creates a stunning contrast that can catch the eye even from a distance. The plant spreads via stolons, which are above-ground shoots that can root at the nodes, leading to the "reptans" part of its name, suggesting a creeping or crawling habit. This hardy ground cover spreads effortlessly, making it a popular choice for filling in patches in landscaped areas or covering larger swathes of ground with attractive foliage and flowers. Despite its fast-spreading nature, Carpet Bugle is not typically considered invasive and can be a welcome addition to many garden settings.

  • water dropWater

    Bugleweed should be watered deeply once or twice a week, allowing the soil to dry out slightly between waterings. It is best to use about 1 gallon of water for each watering session for established plants to ensure the moisture reaches the root system. During the hotter, dryer seasons, frequency may need to be increased. Overwatering can lead to root rot, so ensure good drainage. Adjust water amounts during rainy periods to prevent waterlogged soil.

  • sunLight

    For optimal growth, Bugleweed (Ajuga reptans 'Atropurpurea') prefers partial shade to full sun. Ideal spots are under dappled light of open trees or on the east side of a structure where it gets morning sun and afternoon shade. Too much sun can cause the leaves to scorch, whereas too much shade can lead to leggy growth and poor flowering.

  • thermometerTemperature

    Bugleweed thrives best in temperatures between 60°F and 75°F but can survive minimum temperatures down to around -20°F and can handle summer highs up to about 90°F. It is winter hardy in USDA Zones 3 to 10. Consistent temperatures within the ideal range promote vigorous growth and flowering.

  • scissorsPruning

    Prune Bugleweed in late winter or early spring to remove any dead or damaged foliage and to maintain its appearance. Pruning may also be necessary to control its spread in the garden, as it can become invasive. Pruning right after flowering can stimulate a second bloom and helps to prevent self-seeding.

  • broomCleaning

    As needed

  • bambooSoil

    Bugleweed (Ajuga reptans 'Atropurpurea') thrives in well-drained soils rich in organic matter, with a pH range from 3.5 to 6.5. To create the best soil mix, combine two parts garden soil, one part peat moss, and one part perlite or coarse sand to promote drainage and aeration. Regularly adding compost can help maintain soil fertility.

  • plantRepotting

    Bugleweed rarely needs repotting as it is a ground cover plant which spreads through stolons. Instead of repotting, it is typically divided or thinned out in the garden to control its spread or rejuvenate crowded clusters. Repotting or dividing should be done in the spring or early fall if necessary.

  • water dropsHumidity & Misting

    Bugleweed is not particularly humidity-sensitive and adapts to a wide range of outdoor humidity conditions. It is important to ensure good air circulation around the plants to prevent fungal diseases, particularly if they are grown in a more humid climate or environment.

  • circleLife cycle

    Bugleweed 'Atropurpurea' begins its life as a seed, which upon germination, gives rise to small seedlings. The seedlings develop into juvenile plants with characteristic deep purple leaves. As the plant matures, it forms a dense foliage mat through vegetative propagation, mainly stolons which spread horizontally and root at intervals. During the blooming stage, it produces spikes of blue to violet flowers in late spring to early summer, attracting pollinators. After pollination, the flowers develop into tiny nutlets that disperse to form new plants. In the fall, the foliage may die back, but the plant remains perennial, regrowing from the root system each spring.

    • Propogation time

      Spring to early summer

    • Propogation: Ajuga reptans 'Atropurpurea', commonly known as Bugleweed, is best propagated in the spring or early fall. The most popular method of propagation for this plant is by division. To propagate by division, gently lift a clump of the plant from the ground using a garden fork or shovel, ensuring a good amount of roots are attached to each section. Separate the clump into smaller sections by hand or with a knife, each containing several shoots and a portion of the root system. Replant these divisions immediately into prepared soil at a similar depth to how they were originally growing, spacing them about 12 inches (approximately 30 centimeters) apart to allow for spreading. Water the new plantings thoroughly to settle the soil around the roots and eliminate air pockets. This method allows for a quick and effective way to expand your patch of Bugleweed or to create new patches in different areas of the garden.
