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 in early spring, but be careful not to cut into the old, woody stems that do not have buds unless it needs complete regeneration, as this may kill the plant. It helps if you can wait until the new buds are breaking before tackling it, as this will give you an indication as to where to make the cut. They fill out really quickly after pruning, but the tips may need pinching out to prevent them getting leggy.
