Product Description

Ajuga reptans ‘Black Scallop’ PP15815 30ct FlatCommon Name: Bugleweed, Carpet Bugleweed

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’ 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.

Ajuga grows best in partial to full shade but will also grow in full sun if constant moisture is provided. It will tolerate any soil, even poor ones, as long as it is well-drained. Good air circulation is essential to avoid crown rot.

Ajuga reptans ‘Black Scallop’, also known as the carpet bugle, is a popular groundcover prized for its striking foliage and vibrant blue flowers. This comprehensive guide will provide detailed information about this versatile plant, including its characteristics, care requirements, and landscaping uses.

Ajuga reptans ‘Black Scallop’ is a low-growing, spreading perennial with glossy, near-black leaves. The leaves are slightly more upright and wavy compared to other Ajuga varieties. The deepest foliage color is achieved when plants are sited in full sun and in cooler temperatures. In mid to late spring, short (4-6″) spikes of deep blue flowers stand upright above the foliage. The flowers are fragrant and attract pollinators such as bees and butterflies.

This cultivar is a naturally occurring mutation of Ajuga reptans ‘Braunherz’ that was first observed in 1998. It was subsequently isolated, developed, and introduced into commerce. This Ajuga is a member of the mint family (Lamiaceae). Interestingly, the origin of the genus name Ajuga is unclear.

Ajuga was an ancient medicinal herb and was used as a wound coagulant, which led to its lesser-known common name, “carpenter’s herb”.

‘Black Scallop’ tends to spread more slowly and stay naturally compact compared to other kinds of Ajuga, making it suitable for use as an edging or for smaller spaces. It is also reported to be resistant to powdery mildew. Unlike many perennials that are grown only for their flowers, Ajuga is prized for its attractive, colorful foliage that looks nice all year. In milder climates, it remains evergreen, providing year-round interest in the garden.

Other Care Tips:
