This attractive small-scale groundcover has glossy, near-black, scalloped leaves and a dense habit. The deepest foliage color is achieved when plants are sited in full sun and in cooler temperatures. From mid to late spring, short (4-6") spikes of deep blue flowers stand upright above the low, spreading foliage. The effect is stunning when planted en masse.

'Black Scallop' PP15815 tends to spread more slowly and stay naturally compact compared to other kinds of Ajuga, making it suitable for use as an edging. It also fits nicely into rock gardens and mixed container plantings. It is reported to be resistant to powdery mildew.

A. reptans is an evergreen groundcover that can grow in the shade of large trees where grass is hard to establish. Unlike many perennials that are grown only for their flowers, ajuga is prized for its attractive, colorful foliage that looks nice all year.
