Iceberg Alley, a native plant discovered by the Memorial University of Newfoundland and Labrador Botanical Garden. Powdery, silver foliage of this small shrub is a great addition to the landscape, adding texture and contrast when combined with other shrubs. Forming a rounded shrub and does not overtake the landscape, reaching a height and spread of about 5 (a bit shorter in very cold areas and a bit taller in warmer zones). It blooms in spring with silver catkins, red stamens and nectar for pollinators. Tolerant of moist soils and a good choice for rain gardens. Grows best in full sun and tolerates pruning beautifully. Consider cutting the stems in early spring for the decorative catkins.
