Botanical Name

AJUGA pyramidalis

Plant Common Name

European Bugleweed

General Description

Pyramidal bugleweed is a semi-evergreen groundcover that is named for its pyramidal spikes of indigo blue flowers that appear in late spring to early summer. Shade-loving and tough, plants form clumps of dark green foliage that spread by underground stems. Use as a groundcover in areas where grass can’t survive and foot traffic is light. Provide pyramidal bugleweed with moist, well drained soil for best performance.
