Eucalyptus coerulea R.T.Baker & H.G.Sm.
Eucalyptus leucoxylon pallens Benth.
Eucalyptus sideroxylon pallens (Benth.) Rehder
Common Name: Drooping Ironbark
Eucalyptus caleyi is an evergreen tree that can grow up to 30 metres tall[
The plant is harvested from the wild for its wood.
Australia - New South Wales, southeastern Queensland
Widespread and locally abundant, in grassy woodland on drier, shallower soils of moderate fertility[
]. Stony ridges and hillsides on sandstone, traprock or granite soils; at elevations from 160 - 1,000 metres[

Eucalyptus caleyi is native to the warm temperate and subtropical climate of eastern Australia, growing in a region where rainfall occurs mainly in the summer. Mean annual rianfall is within the range 630 - 750mm, and there can be from 20 - 60 frosts each year[
Eucalyptus species generally require a sunny position, succeeding in a wide range of well-drained, circumneutral soils of low to moderate fertility[
The plant develops a lignotuber - this is a woody tuber that starts to develop near the base of seedlings and can become massive in the mature plants of some species. It possesses embedded vegetative buds, allowing the plant to regenerate following crown destruction, for example by fire[
This species is one of the ironbark group of Eucalypts. The resin exudes into the bark then hardens making the bark very hard and difficult to cut through with primitive tools[
Eucalyptus species have not adopted a deciduous habit and continue to grow until it is too cold for them to do so. This makes them more susceptible to damage from sudden cold snaps. If temperature fluctuations are more gradual, as in a woodland for example, the plants have the opportunity to stop growing and become dormant, thus making them more cold resistant. A deep mulch around the roots to prevent the soil from freezing also helps the trees to survive cold conditions[
]. Many members of this genus are remarkably adaptable however, and there can be a dramatic increase in the hardiness of subsequent generations from the seed of survivors growing in temperate zones[
The flowers are a very good source of nectar for bees[
An essential oil is obtained from the leaves. Total quantity of the oil, and its composition, can vary widely from plant to plant, but we have reports that the fresh leaves contain around 0.4 - 0.8% essential oil. The main components vary widely, with some forms of the plant having up to 34% bicyclogermacrene, other plants contain up to 53% 1,8-cineole[
The deep red heartwood is very heavy, very hard, strong and durable[
]. It is used locally for posts etc[
The wood makes a good fuel[
Seed - surface sow late winter/early spring in a sunny position in a greenhouse[
]. Species that come from high altitudes appreciate 6 - 8 weeks cold stratification at 2°c[
]. Pot up the seedlings into individual pots as soon as the second set of seed leaves has developed, if left longer than this they might not move well. Plant out into their permanent positions in early summer and give them some protection from the cold in their first winter. The seed can also be sown in early summer, the young trees being planted in their final positions in late spring of the following year. The seed has a long viability[
