More About Ajuga ‘Caitlin’s Giant’

Ajuga ‘Caitlin’s Giant’ is one of the largest ajuga varieties available, valued for its oversized foliage and rapid spreading habit. Its broad, glossy leaves create immediate visual impact and quickly knit together to form a dense groundcover, making it especially useful for covering large or challenging areas. In spring, tall spikes of rich blue flowers rise well above the foliage, adding vertical interest and attracting early-season pollinators.

Because of its vigor, this variety is best suited for spaces where fast coverage is desired rather than tight edging. It performs especially well beneath trees, along slopes, and in mass plantings where its size and strength can be fully appreciated.
