About

Eucalyptus delegatensis, the alpine ash, is a majestic, tall evergreen tree with a straight, clean trunk, brown to blue-grey and white bark that sheds in strips from branches while remaining persistent on the trunk, and an open, airy canopy of dull-green, glaucous-tinted, aromatic, tapering leaves. White flowers in clusters of up to 15 appear in midsummer, highly attractive to bees. Mature specimens can reach 60 m � a tree for large gardens or parkland.
