Baby Blue Eucalyptus / Silver-Leaved Mountain Gum / Florist Silver Dollar
Botanical Name: Eucalyptus pulverulenta ‘Baby Blue’
Family: Myrtaceae
Origin: Australia (NSW)
Plant Type: Evergreen tree
Overview
Eucalyptus ‘Baby Blue’ is a compact, highly ornamental gum prized for its powdery silver-blue, coin-shaped foliage on red-tinged stems — a favourite for cut foliage/floristry and year-round garden structure. In SA gardens it forms a tidy small tree and produces cream-white blossoms in winter–spring that feed bees and birds. Ideal as a feature, for low-maintenance native/mediterranean schemes, and striking container specimens.
