bugle 'Purple Torch'


The Ajuga reptans 'Purple Torch', commonly known as Bugleweed, is a perennial plant celebrated for its vibrant foliage and attractive flowering spikes. The leaves of Bugleweed are typically rich green to deep burgundy-purple, providing a striking contrast when planted among lighter-colored plants. Each leaf is oval-shaped with a rounded tip and a subtle sheen, accompanied by a texture that can be described as both firm and lush. During its blooming period, Bugleweed produces upright spikes on which tubular flowers are densely packed. These flowers are often a deep blue or violet hue, and they rise elegantly above the foliage. The visual impact of these floral spires is eye-catching, as they add both color and vertical interest to the plant's overall appearance. The growth pattern of Bugleweed is spreading and mat-forming, which allows it to create a lush, ground-covering carpet in the landscapes where it is planted. Its overall presence is one of a hardy plant with an ornamental allure that is simultaneously bold and delicate. While this plant is relatively low-maintenance, it thrives best when given the proper growing conditions, which includes adequate sunlight and moist soils. This allows Bugleweed to showcase its quintessential charm with both its colorful leaves and blossoms, making it a favorable choice for gardeners looking to add both texture and a splash of color to their outdoor spaces.

  • water dropWater

    Carpet Bugle should be watered deeply enough so that the water reaches the roots, approximately once or twice a week depending on weather conditions. During periods of drought or hot weather, increase watering frequency to ensure the soil remains moist but not waterlogged. A good rule of thumb is to provide about one to two inches of water per week. Less frequent but thorough watering encourages deeper root growth and can make the plant more drought tolerant. Always check the top inch of soil for dryness before watering as overwatering can lead to root rot.

  • sunLight

    Carpet Bugle thrives best in partial to full shade, which makes them ideal for woodland gardens or as ground covers under trees. They can tolerate some morning sun, but in regions with strong sunlight, shield them from the harsh afternoon rays. A spot that offers dappled sunlight throughout the day is optimal, which can be provided by planting them under a canopy of trees with filtered light.

  • thermometerTemperature

    Carpet Bugle is hardy and can withstand a range of temperatures, but it flourishes in conditions between 60 and 75 degrees Fahrenheit. They can tolerate winter cold down to about -20 degrees Fahrenheit but should be protected from severe cold winds. During the summer, ensure they have adequate shade if temperatures rise above 80 degrees Fahrenheit to prevent scorching of the leaves.

  • scissorsPruning

    Carpet Bugle requires minimal pruning, mainly to maintain its appearance and health. Trim back any dead or damaged foliage in early spring to encourage new growth. If desired, after the plant flowers, cut back the flower spikes to keep the planting neat and to possibly encourage a second flush of blooms. The best time for general pruning is in the spring or immediately after flowering.

  • circleLife cycle

    Bugleweed 'Purple Torch', a perennial herb, starts its life cycle with seed germination in favorable conditions of moisture and temperature, typically in spring. Seedlings develop into rosettes with a central cluster of leaves, expanding by producing creeping stolons that root at nodes to form new plantlets. Throughout spring and summer, the plants grow vegetatively, with lush purple foliage and preparing for the next stage. By late spring to early summer, Bugleweed 'Purple Torch' flowers, producing purple to violet flower spikes that attract pollinators, and after pollination, seeds develop. As the flowering phase ends, the plant focuses energy on strengthening the roots and stolon system for survival. In winter, Bugleweed 'Purple Torch' enters dormancy, with above-ground parts dying back in colder climates, while the roots and stolons survive underground to restore growth in the next spring.

      Spring-Early Summer

    • Ajuga reptans 'Purple Torch', commonly known as bugleweed, is most commonly propagated by division. This simple method involves gently separating the plant's rooted sections during its active growth period, which is typically in the spring or fall when temperatures are mild. To propagate bugleweed by division, carefully dig up an established clump and use your hands or a sharp knife to divide the root ball into smaller sections, ensuring that each new section has at least a couple of healthy leaves and roots. Replant these divisions at the same depth they were growing at previously, spacing them about 6 to 12 inches (15 to 30 centimeters) apart to allow room for growth. Water the new plantings well to help establish them. This method leverages the plant's natural tendency to form dense mats and can quickly produce new plants that will bloom in subsequent seasons.
