Powis Castle Artemisias are shrubby, mound forming perennials are grown for their finely dissected,
aromatic, silvery-blue foliage. Powis Castle plants are evergreen (eversilver?) in warm winter regions.
They form soft mounds that grow 2-3 feet tall and wide,
but they spread underground rhizomes and can eventually reach 6 feet.
Powis Castles are excellent plants for providing contrast and accent between groups of flowering plants,
as well as for backgrounds or in the herb garden.
Coza the Garden Gnome They are very drought tolerant plants once established. They are deer resistant, and adapt well to growing near the seaside, or growing in planters.

Growing Requirements for Artemisia 'Powis Castle'

Powis Castle Artemesias are hardy in USDA zones 6-10.
Powis Castle plants should be grown in full sun, except in hot summer regions where they will require partial shade. They are not overly fussy about the soil they grow in, as long as it drains well, but they benefit from the addition of compost to the planting hole.
Water regularly and deeply during the first growing season to establish a strong root system, then reduce watering to only when the soil dries out.
Artemisias are subject to root rot in wet or soggy soils, especially in the winter.

Powis Castle Artemesias almost never flower, but if they do, the buds should be snipped off before they open
to preserve the appearance and shape of the plant.

Pruning and Propagating Powis Castle Artemisia Plants

The foliage of Powis Castle plants can be sheared lightly during the summer for grooming purposes. Plants that get lanky or begin to fall during the summer can be cut back by 1/3. New foliage will quickly fill back in. , Any major pruning should be done in the spring after the new buds begin growing. Make any pruning cuts above the new bud growth. Never cut stems back into woody growth or cut them all the way to the ground.

Because Powis Castle Artemisias are hybrid plants, they will not produce viable seeds, therefore new plants can only be propagated from cuttings taken early in the summer, or by digging and dividing mature plants early in the spring.
