Catlin's Giant Carpet Bugle – Large-Leaved Groundcover with Blue Spikes

Catlin's Giant Carpet Bugle

For a bolder groundcover presence, Catlin's Giant Carpet Bugle (Ajuga reptans 'Catlin's Giant') delivers. It forms a dense, weed-smothering mat of larger, bronze-blue foliage, topped in spring by deep blue flower spikes. Even in shady areas, it creates a thick, carpet-like cover.

This perennial thrives in full sun to partial sun with moderate moisture. Stays under 2 feet tall and spreads 1–2 feet. Excellent for large-scale groundcover, underplanting shrubs, or stabilizing slopes. The larger leaves give it a more substantial texture than standard Ajuga.
