💜 Ajuga (Bugleweed): A Fast-Spreading Carpet of Color and Texture

If you need a plant that can quickly fill space, suppress weeds, and still look beautiful, Ajuga—commonly called bugleweed—is one of the most effective groundcovers you can grow.

With its low, spreading habit, colorful foliage, and spring flower spikes, Ajuga creates a dense, living carpet that works especially well in areas where grass struggles.
