Description
Powis Castle is a fragrant bushy sub-shrub, prized for its fern-like, silvery-white foliage that complements flower bulbs and other perennials well. Its yellow flowers emerge in late summer or early fall, though they are not particularly showy. The nature of this plant makes it perfect for flower beds and borders. At maturity this plant can grow to measure 2 to 3 feet tall and 3 to 6 feet wide. It thrives in poor moderately moist soil, in full sun, with average watering. Powis Castle is drought tolerant and has hardiness zones from 6 to 9.
