Artemisia 'Powis Castle'
Artemisia is a genus comprising approximately 200 evergreen and deciduous shrubs, perennials, and annuals, mainly found in dry temperate regions of the Northern Hemisphere. Many species have aromatic, pinnately divided, or finely dissected silvery-green foliage and inconspicuous flowers.
The genus is named after Artemis, the Greek goddess of the moon, wild animals, and hunting.
'Powis Castle' is likely a hybrid between Artemisia arborescens (large wormwood) and Artemisia absinthium (absinthe wormwood). It is a bushy, woody-based perennial or subshrub primarily cultivated for its aromatic, finely divided, silvery, fern-like foliage, which has a feathery appearance. Usually, it grows into a shrubby mound reaching 2-3 feet tall and wide, but it spreads through rhizomes and can grow to be 3-6 feet wide if not contained. It rarely produces tiny yellow-tinged silver flowers. In warm winter climates, these plants are essentially evergreen.
'Powis Castle' was introduced in 1972 from the National Trust's Powis Castle in Wales. Allan M. Armitage regards 'Powis Castle' as "one of the finest plants in cultivation," it received the 1993 RHS Award of Garden Merit.

Winter Shipping: We will continue to ship throughout winter. If you prefer, we are happy to hold your order until spring; please include that request in your shipping notes.
When you order plants from our nursery, you can expect them to arrive in the best possible condition. Our team carefully packs each order using sturdy, biodegradable packaging materials.
Your plants' appearance may vary depending on the season and their current growth stage. We may cut back the leafy growth of some plants to prepare them for shipment and transplanting.
5 Gallon and Up: Any plant purchased to ship over 5 Gallons will be shipped bare root. This means we will remove the plant from its original pot, remove the soil surrounding the roots, and wrap the roots with a biodegradable plastic bag. This reduces weight and the likelihood of damage during shipping.
Once your plants arrive, it is essential to plant them as soon as possible. This will help them rebound and thrive. If you cannot plant immediately, water regularly and keep the roots off heat-conducting surfaces.
Newly transplanted plants often require more water until their roots are well established. Plan to water them 1-3 times weekly for the first few months.
