Cider Gum
Eucalyptus gunnii
treeEucalyptus gunnii is a fast-growing evergreen tree native to Tasmania, known for its silvery-blue juvenile foliage and peeling bark that reveals cream and pink undersides. It produces small white flowers and develops into a tall, elegant specimen tree that can reach 40-60 feet in ideal conditions. This hardy eucalyptus is one of the most cold-tolerant species and is prized for its aromatic foliage and ornamental appeal.

Seedling & Juvenile
6-12 monthsTiny seedlings with distinctive silver-blue rounded leaves; extremely rapid growth rate with soft stems
Keep soil moist but not waterlogged; provide bright light; protect from frost in early stages; thin seedlings early to prevent competition
Young Tree (Establishment)
2-4 yearsDevelops primary trunk and main branch structure; maintains juvenile blue foliage initially, gradually transitions to adult lance-shaped green leaves; height increases 2-3 feet per year
Water deeply but infrequently once established; stake for wind support; remove competing leaders to establish single trunk; avoid fertilizing—promotes weak growth
Maturing Tree
5-10 yearsTransitions to adult foliage; bark begins distinctive peeling; crown fills out with dense branching; height 20-40 feet
Minimal water supplementation in most climates; mulch around base to retain moisture; prune only to remove crossing or damaged branches; strong wind tolerance develops
Flowering
4-8 weeks, recurring annually once matureSmall white, cream, or pale pink flowers appear in clusters along stems; flowers attract pollinators; blooms occur at branch tips
Flowers typically appear spring to early summer; deadheading optional as flowers naturally drop; flowers produce abundant nectar
Mature Tree
Ongoing (decades)Fully developed specimen with characteristic exfoliating bark creating multi-colored trunk; lance-shaped adult foliage; height 40-60+ feet; dense rounded crown
Minimal care required; drought-tolerant once established; monitor for storm damage; remove dead branches; very long-lived (80+ years)

Harvest Tips
Harvest foliage year-round for cut flowers and arrangements; best flavor/aroma when young, before 10 a.m.; cut stems just above leaf nodes to encourage branching; foliage dries well for dried arrangements and potpourri; can be coppiced (cut back to ground) in early spring to promote renewal and maintain juvenile blue foliage
Fun Facts
- 🌱 Eucalyptus gunnii is one of the hardiest eucalyptus species, surviving temperatures down to -8°C (18°F) when established, making it the most cold-tolerant eucalyptus commonly grown outside Australia.
- 🌱 The common name 'Cider Gum' comes from early settlers' attempts to ferment the sap, though it never became a successful alternative to apple cider.
- 🌱 The distinctive peeling bark is a natural adaptation that helps shed insects and disease while reflecting heat; the underlying bark is vivid orange, cream, or pink, creating striking multi-colored trunks.
