Wormwood 'Powis Castle'
A mid-sized compact mound, as dense as mercury, with feathery aromatic foliage that provides the perfect silver contrast to all cottage flowers. Tolerant of high winds and salt spray, ‘Powis Castle’ makes an effective hedge if given a hard prune every spring to keep it compact. The essential low maintenance garden backbone for pastel colour schemes.
Thrives in full sun or part shade, poor to moderately fertile, dry to moist soil, drought-tolerant once established. Requires free-draining soil. Suitable for hedging; prune hard in spring to maintain a dense compact habit. Tolerant of high winds and salt spray.
