It is known to spread quickly enough via runners to become invasive in some areas. The reptans part of its Latin name means "to creep." It is a naturalized North American plant introduced from several places in Europe and Asia. Ajuga Reptans grow well in Hardiness Zones 3 through 10. They are susceptible to most dirt, though they prefer slightly acidic. Fully grown plants generally stand 6" to 8" high; flower stalks can grow to 12". Each plant may extend up to 12". They quickly form mats, especially in shaded areas beneath other trees and shrubs. The plant is hardy enough to grow beneath black walnut trees.

The plant is best planted in rock gardens, container-edged beds, or wide-open areas that need ground cover quickly. It lends itself well to erosion control. It should not be planted near any less hardy flowers at home, as it may choke them out.
