Artemisias are prized for their light almost silver aromatic foliage rather than for their flowers which are dull and insignificant. This cultivar has fine fern-like aromatic leaves and tiny yellow-tinged silver flowers in August. The billowing foliage of this woody stemmed perennial is ideal for a sunny rock garden or border. Although it's one of the hardiest varieties of wormwood do plant it in a well-drained site as the plant is likely to be short-lived in poorly drained soil.
- Garden care: Cut back stems back to ground-level in autumn and apply a generous mulch of well-rotted garden compost or manure around base of the plant.
