Angelica sylvestris Ebony Superior By far the darkest of the Angelica's we have trialed here, this perennial forms a rosette of near black delicately divided foliage. During early Summer, dark flower stems carry broad umbels of purple buds, which open to soft pink. A dramatic plant, much loved by Diggers staff, as it flowered in our trial gardens. Perfect to plant amongst feathery grasses and hazy perennials.
