Black Scallop Bugleweed

Ajuga reptans ‘Black Scallop’ is an evergreen-to-semi-evergreen groundcover with glossy, dark maroon-purple scalloped leaves and short spikes of deep violet-blue flowers. Its [plant patent](https://patents.google.com/patent/USPP15815P2/en) describes a compact plant about 20 cm tall and 30–40 cm wide; [Walters Gardens](https://www.waltersgardens.com/variety.php?ID=AJUBS) notes that foliage is darkest in full sun and cooler temperatures. Patent PP15815 was issued in 2005. ## Garden use and season Use it as a low edging, in a rock garden, or to cover soil beneath shrubs and trees. Spring flowers rise above the dark foliage, and the persistent leaves provide structure after the bloom season. It spreads by stolons, so place it where a groundcover can expand and keep it away from lawns or small perennial beds if containment matters ([Walters Gardens](https://www.waltersgardens.com/variety.php?ID=AJUBS); [RHS](https://www.rhs.org.uk/plants/742/ajuga-reptans/details)). ## Growing conditions Grow in moist but well-drained soil in partial shade or shade; it can also grow in sun when moisture is steady. The patent identifies this cultivar as more heat tolerant and more resistant to powdery mildew than its comparison cultivar, though crowded or humid sites can still develop crown rot. ## Maintenance Water new plants while they establish and during extended dry weather. Remove unwanted runners at the edge of the patch, and improve airflow in hot, humid locations. Cut back old flower spikes only if they look untidy; routine pruning is generally unnecessary.
