More About Ajuga ‘Black Scallop’

Ajuga ‘Black Scallop’ is widely regarded as one of the darkest-foliaged ground covers available, prized for its glossy, near-black leaves with deeply scalloped edges. The dramatic foliage forms a dense, low-growing mat that provides season-long color and excellent weed suppression, making it both ornamental and highly functional in the landscape.

In spring, short spikes of rich blue flowers rise above the dark foliage, creating striking contrast and adding an extra layer of seasonal interest. While the flowers are attractive to bees and other early pollinators, the foliage remains the primary draw, holding its deep color through summer and into fall.

Why We Like It (Our Trials)

In our trials, ‘Black Scallop’ has proven to be a tough, adaptable ground cover that performs well in a range of conditions. It spreads steadily without becoming aggressively invasive and fills in bare areas quickly once established. Partial shade tends to produce the richest foliage color, though it tolerates full sun with adequate moisture.

We also appreciate its versatility. It works beautifully as a living mulch beneath trees and shrubs, along pathways, or spilling over the edges of containers. Deer consistently avoid it, and its low profile makes it easy to maintain with minimal intervention.

Ajuga ‘Black Scallop’ vs. Other Ajuga Varieties

Compared to more traditional green or bronze ajuga selections, ‘Black Scallop’ offers dramatically darker foliage and a more refined, ornamental look. While varieties like ‘Chocolate Chip’ stay very low and spread quickly, ‘Black Scallop’ provides a bolder visual statement with larger leaves and a richer, glossier finish.

For gardeners looking to add contrast, texture, and dependable coverage in shaded or partially shaded areas, Ajuga ‘Black Scallop’ remains one of the best ground cover choices available.
