'Powis Castle' Wormwood has showy silver foliage with a finely textured appearance, and needs a dry site. The foliage is sharply aromatic.  The hybrid was selected by British gardener A. J. Hancock in the late 1960's, and used to line walls and terraces surrounding the castle.  Sold to promote the National Trust gardens, it was introduced in 1972 by the National Trusts’ Powis Castle in Wales.
