Dormancy: Evergreen Height: 3″ tall Culture: Part Sun to Light Shade Origin: Europe Ajuga ‘Black Scallop’ is a superb and colorful evergreen groundcover that exists thanks to UK nurseryman Mike Tristam, who found it as a tissue culture mutation in a batch of Ajuga reptans ‘Braunherz’. Ajuga ‘Black Scallop’ acts like a typical ploidy (doubled sets of chromosomes) mutant with larger, darker purple leaves and flowers than its parent, as well as better disease tolerance. The heat-tolerant dense mat of crinkled, glossy purple foliage is topped in late spring with stunning stalks of blue-purple flowers. Tired of mulching? Put this attractive ajuga to work in your garden as a living mulch. Average to slightly moist soils are best.
