  • Candlebark


Tree Register of Ireland.
Diameter (of trunk) at breast height. Breast height is defined as 4.5 feet (1.37 m) above the ground.
(of fruit) Vernacular English term for winged samaras (as in e.g. Acer Fraxinus Ulmus)
(subsp.) Taxonomic rank for a group of organisms showing the principal characters of a species but with significant definable morphological differentiation. A subspecies occurs in populations that can occupy a distinct geographical range or habitat.

Tree 30–40 m, 1 m dbh. Bark smooth, white, red or reddish brown throughout; wild specimens often have horizontal insect scars. Branchlets greenish yellow to red. Juvenile leaves sessile, opposite, circular or elliptical and glaucous. Adult leaves thick and dull greyish green or glaucous, 9–15 × 0.8–1.5 cm, lanceolate to narrowly lanceolate, falcate, lateral veins distinct, margins entire, apex acute; petiole terete, 1.3–2.5 cm long. Inflorescences simple and axillary; umbellasters with three to seven flowers. Flower buds ovoid and often glaucous; hypanthium 0.4–0.5 cm wide; stamens white or cream. Capsule hemispherical to subglobular, 0.5–0.7 cm diameter; valves three to four, exserted. Boland et al. 1984, Chippendale 1988. Distribution AUSTRALIA: New South Wales (east), South Australia (Mt. Lofty Range), Tasmania (eastern plateau), Victoria (east). Habitat Woodland and open forest with shallow soils on plateaus, tablelands and hills, between 75 and 1400 m asl. USDA Hardiness Zone 8. Conservation status Not evaluated. Illustration NT359. Taxonomic note Similar to E. dalrympleana, but with glaucous juvenile leaves and white, red or reddish brown bark.

In cultivation distinctions have not been made between the four subspecies of Eucalyptus rubida, but as these seem to be useful and perhaps a pointer to different provenances, a key is provided below (modified from that of Hill & Johnson 1991a).


Umbellasters three-flowered



Umbellasters seven-flowered; Australia (New South Wales, Victoria)

subsp. septemflora L.A.S. Johnson & K.D. Hill


Trunk smooth to base; juvenile leaves circular



Trunk with short, black stocking at base; juvenile leaves elliptical; Australia (New South Wales: Northern Tablelands)

subsp. barbigerorum L.A.S. Johnson & K.D. Hill


Coppice shoots terete; juvenile leaves mostly < 4 cm wide; Australia (South Australia, Tasmania)

subsp. rubida


Coppice shoots quadrangular; juvenile leaves mostly > 5 cm wide; Australia (New South Wales: Mt. Canobolas)

subsp. canobolensis L.A.S. Johnson & K.D. Hill

The variability seen in Eucalyptus rubida should probably be more carefully investigated in horticulture; what is not in doubt, however, is that it can be an extremely beautiful tree. The rounded juvenile foliage is often an excellent blue colour, but may also show red tints as it flushes. In mature specimens the often multicoloured smooth bark is an important feature. When happy it can grow fast, young trees in Portland, Oregon achieving 10 m in five years (S. Hogan, pers. comm. 2007). It is reasonably hardy – there are mature specimens at the Celyn Vale Eucalyptus Nurseries near Corwen, Clwyd – but the largest recorded in the British Isles, at Castlewellan, Co. Down, was 25 m (58 cm dbh) in 2000 (TROI).
