A compact, rounded shrub distinguished by its exceptionally bright, silvery foliage. The narrow leaves are covered with fine hairs, giving the plant a cool, almost icy appearance that contrasts beautifully with green perennials and darker shrubs in mixed borders. In spring, before the leaves are fully developed, ornamental silvery catkins with red stamens appear and are highly attractive to pollinating insects. The plant typically reaches 1–1.5 m in height, has a dense, compact habit, and responds well to pruning. It performs best in full sun and in moist to wet soils, making it particularly suitable for planting near ponds, water features, and in rain gardens. The cultivar is frost hardy and easy to maintain. Hardiness zone: 2 (–45 to –40°C).
