Ajuga reptans 'Black Scallop'


Black Scallop is a stoloniferous, mat-forming, bugleweed cultivar that is noted for its (1) dark maroon-purple leaves with scalloped margins, (2) fragrant dark violet flowers and (3) compact but spreading habit. Leaves are varyingly described as dark maroon-purple to near black, which gets the point across that these leaves are in fact very dark in color. Leaves appear in spreading rosettes that form a 3-4" tall foliage carpet that may spread over time to 36" wide. Tiny, two-lipped, dark violet flowers (typical of the mint family) appear in late spring on flower spikes that rise above the foliage. Flowers are attractive to early butterflies and other beneficial pollinators.

Homeowner Growing & Maintenance Tips for Bugleweed

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Prefers moist, humusy soils with good drainage, but tolerates moderately dry ones. Best dark leaf color usually occurs in sunny locations. Divide when clumps become overcrowded. This is a fast-growing plant that will spread by stolons to form an attractive ground cover. Larger plantings may be mowed on a high mower setting to remove spent flower spikes and to tidy the appearance of the planting. String trimmers and hedge shears are also effective for removing spent flower spikes. Space plants 6-9" apart for quick cover. This is a patented plant that will not reproduce by seed.

Interesting Notes

Technically, this plant is correctly identified as Ajuga reptans 'Binblasca'. Black Scallop is the trademark name for this patented plant, but is also the name under which it is most commonly known. Black Scallop was first observed in 1998 as a natural mutation that occurred in an in vitro (tissue culture) nursery laboratory planting of Ajuga reptans 'Braunherz'. It was subsequently isolated, developed and introduced into commerce to wide acclaim.
