Common Name: Red Tingle

General Information

Eucalyptus jacksonii is an evergreen tree with a dense, compact crown; it can grow from 55 - 70 metres tall. The straight bole can be 200 - 450cm in diameter and has large buttresses[, ].
The tree is harvested fom the wild for its wood.

Cultivation Details

Eucalyptus jacksonii is native to the Mediterranean climate of southwestern Australia, where it is found at elevations up to 100 metres. Summers are warm and dry, with most rainfall occurring in the winter months and a dry season of up to 3 months. Mean annual rainfall is within the range 1,250 - 1,500mm; mean maximum temperature of the hottest month is 21 - 24°c; mean minimum temperature of the coldest month is 7 - 10°c, and there are generally very few frosts a year and these are very light[]. When dormant, the plant can survive temperatures down to about -2°c, but young growth is more tender and can be severely damaged at 0°c[].
Requires a sunny position, succeeding in a range of light to medium-textured, well-drained soils of 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[].
There are very limited prospects for planting this tree outside its native range because there are few places in the
world as mild and yet moist and without frosts as its native habitat. It grows well on Matakana Island off the north coast of New Zealand, it failed in Brazil and grew fairly well in trials in South Africa[].
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

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 1.0% (dry weight) essential oil. The main components include jacksonone (60%) and cryptone (6%)[].

The deep pink to reddish brown wood is strong, tough, durable, straight grained, with a density of 720 kg/m3. Easily worked, it is used for home construction, sleepers and furniture. One of the best woods in Western Australia but not used much because of location[, ],

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[].
