From late spring, Ajuga reptans 'Black Scallop' produces violet blue flower spikes that really stand out against its thick mat of shimmering black foliage - which becomes even darker when grown in full sun. ?Black Scallop? is more tolerant of sun that many other Bugle varieties, and makes an excellent groundcover plant, thriving in almost any soil conditions. Use it to attract pollinating insects to your wildlife garden, or allow it to creep through rockeries or the front of borders. Height: 15cm (6). Spread: 60cm (24).
