Description
Artemisia ‘Powis Castle’ – Artemisia arborescens ‘Brass Band’ – This woody based mounding perennial is a cross between Artemisia absinthium and Artemisia arborescens and grows 2’ feet tall and spreads to 3’ feet or more wide. It produces pinnatisect or 2 pinnatisect, feathery silver-gray leaves, 2 ½” long with linear lobes. In late summer it bears panicles to 6” long of silver, yellow-tinged flower heads are seldom produced.
Grow these quite frost hardy plants in well-drained fertile soil in full sun although they can withstand hot dry areas and considerable drought. Cut down to base in autumn, cut shrubby species back hard in spring to maintain a compact habit and stimulate new growth. Divide in spring or in autumn.
