With dissected silver-gray foliage, 'Powis Castle' Artemisia is the perfect companion plant to use with other flowering perennials and ornamental grasses to bring out interesting contrasts of leaf color and texture. It almost never flowers, thus maintaining its neat appearance with no extra effort. Not at all fussy as to soil type, 'Powis Castle' is also quite drought tolerant. Prune back to 6" tall in mid-spring to reinvigorate plant each year.
