Common Name: Blue-leaved Stringybark

General Information

Eucalyptus agglomerata is an evergreen tree that can grow 20 - 30 metres tall, sometimes reaching 40 metres. The bole can be 60 - 100cm in diameter[, ].
The tree is harvested from the wild for local use as a source of materials.

Cultivation Details

Eucalyptus agglomerata is a plant of the temperate zone of southeastern Australia, where it is found at elevations up to 1,000 metres. It grows best in areas where annual daytime temperatures are within the range 18 - 28°c, but can tolerate 8 - 37°c[]. When dormant, the plant can survive temperatures down to about -5°c, but young growth is more tender and can be severely damaged at 0°c[]. It prefers a mean annual rainfall in the range 800 - 1,000mm, but tolerates 700 - 1,150mm[].
Requires a sunny position, succeeding in a range of well-drained soils of low to moderate fertility[]. Prefers a pH in the range 5.5 - 6.5, tolerating 5 - 7[].
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[].
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[].

Other Uses

Twine can be made by rolling the fibres of soaked bark against the thigh and twisting two strands together[].
The bark from stringybarks can also be used to maks huts, shields and water carriers[].

The bark was used traditionally to make canoes[].

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 0.9 - 1.4% essential oil. The main components include tasmanone, agglomerone and spathulenol[].

The heartwood is light brown, the sapwood pale brown. The wood is moderately fine textured. It is used for general building construction and fencing[].

Propagation

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[].
