How to Grow and Control Variegated Creeping Charlie

Variegated creeping charlie, known scientifically as Glechoma hederacea ‘Variegata’, is a groundcover plant recognized by its distinctive green leaves edged with white or cream. It exhibits vigorous growth, making it popular for quickly covering areas or spilling from containers. This plant has a dual reputation, cherished by some for its ornamental qualities while considered a persistent garden weed by others.

Recognizing Variegated Creeping Charlie

Glechoma hederacea ‘Variegata’ is identifiable by several key features. Its leaves are rounded to kidney-shaped with scalloped or toothed edges. The variegation appears as creamy white or pale yellow borders along the leaf margins, contrasting with the green center. The plant exhibits a trailing, vining growth habit, spreading readily across the ground. In spring, small, trumpet-shaped purple or blue flowers emerge.

The stems of variegated creeping charlie are square, a defining trait of plants belonging to the mint family (Lamiaceae). This square stem, along with its scalloped, often fuzzy leaves, helps distinguish it from other similar-looking plants like Creeping Jenny (Lysimachia nummularia), which has smoother, non-scalloped leaves. When crushed, the foliage emits a minty aroma.

Understanding Its Nature

Variegated creeping charlie evokes varied responses from gardeners. Some cultivate it as an ornamental plant, appreciating its quick-spreading nature as a low-maintenance groundcover or for its attractive foliage in hanging baskets and window boxes. Its ability to thrive in shaded areas where other plants might struggle also makes it a desirable option for some landscapes.

Conversely, many gardeners perceive variegated creeping charlie as an invasive weed. Its aggressive spreading habit is facilitated by stems that root readily at nodes wherever they touch the soil, creating dense mats that can outcompete and smother other desired plants. This vigorous growth and tendency to take over garden spaces contribute to its reputation as a nuisance, particularly in regions where it is considered an invasive species.

Growing Variegated Creeping Charlie

For those who wish to cultivate variegated creeping charlie as an ornamental plant, providing optimal growing conditions encourages healthy growth while potentially managing its spread. The plant prefers partial to full shade, though it can tolerate some sun if provided with sufficient moisture. Direct, intense sunlight can scorch its delicate leaves.

The plant thrives in well-draining, consistently moist soil. While it can tolerate various soil types, rich, loamy soil is ideal. Keep the soil evenly moist but avoid waterlogging, which can lead to root rot.

Variegated creeping charlie tolerates a range of temperatures, performing well in moderate to high humidity conditions. Fertilization requirements are minimal; a balanced, water-soluble fertilizer diluted to half strength can be applied monthly during the growing season if desired, but over-fertilization can encourage excessive growth. Growing it in containers or hanging baskets is an effective way to manage its vigorous spreading habit, preventing it from taking over garden beds.

Controlling Variegated Creeping Charlie

When variegated creeping charlie is considered an unwanted weed, several strategies can be employed for effective control and removal. Manual removal is an option for smaller infestations, involving hand-pulling the plants. It is important to remove all root fragments, as even small pieces can regrow into new plants. Soaking the soil beforehand can make hand-pulling easier by loosening the roots’ grip.

Cultural practices can also help suppress its growth. Improving lawn health by maintaining dense, healthy turf can help it outcompete the weed. Proper mulching in garden beds creates a barrier that inhibits its spread. Ensuring good soil drainage and aeration, especially in areas where creeping charlie thrives due to compacted or moist conditions, can make the environment less favorable for its growth.

Chemical control can be considered for larger infestations, using broadleaf herbicides that specifically list “ground ivy” or “creeping charlie” on their labels. Herbicides containing active ingredients like triclopyr, 2,4-D, dicamba, or MCPP are effective.

The most effective time for application is in the fall, as the plant is actively sending nutrients to its roots, allowing the herbicide to be transported throughout the plant for better control. A second application may be necessary in the spring when the plants are in bloom. Always follow product instructions carefully and take safety precautions to avoid harming desirable plants.
