Artemisia lactiflora 'Rosenschleier'
A vigorous and impressive hardy perennial which forms low clumps of fern-like dark green leaves. In summer the tall dark purple flower stems appear, smothered in a cloud of tiny pink and white flowers. Flowering continues until autumn, when the stems can be cut back. Winter dormant in very cold areas. Divide every few years. Prefers a sunny position, not too fertile. 1.5-1.8m H x 60-80cm W. 1 litre pot.
