Eucalyptus pauciflora

Family: Myrtaceae

What it is like

Eucalyptus pauciflora is an evergreen Tree growing to 12 m (39ft) by 6 m (19ft) at a fast rate. See above for USDA hardiness. It is hardy to UK zone 8. It is in leaf all year, in flower from July to August. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees. It is noted for attracting wildlife. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry moist or wet soil and can tolerate drought. The plant can tolerate maritime exposure.

Height (m): 12

Where it is found

Edges of frosty treeless valleys in mountains to 1500 metres and down to sea level in W. Victoria.

Fairly tolerant of maritime exposure, though the foliage may be burnt by stronger winds. It can be grown as a shelterbelt tree. Wood - soft, not durable, apt to warp. It is used for fence rails, fuel etc.

Fuel: Usually wood, plant materials that have been mentioned as being a good fuel.

Shelterbelt: Wind resistant plants than can be grown to provide shelter in the garden etc.

How it is grown

Prefers a sunny position in a moderately fertile well-drained moisture retentive circum-neutral soil. Succeeds in most soils but dislikes chalk or clay soils. Tolerates poor soils, especially those low in mineral elements. Tolerant of dry soils, drought and exposed maritime positions, though its foliage may be burnt in such a position. A fairly hardy species, it tolerates long periods down to -8°c and short periods to -14°c, though it should not be planted in a frost pocket. 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. The members of this genus are remarkably adaptable however, there can be a dramatic increase in the hardiness of subsequent generations from the seed of survivors growing in temperate zones. Eucalyptus monocultures are an environmental disaster, they are voracious, allelopathic and encourage the worst possible attitudes to land use and conservation. Plants are shallow-rooting and, especially in windy areas, should be planted out into their permanent positions when small to ensure that they do not suffer from wind-rock. They strongly resent root disturbance and should be container grown before planting out into their permanent position. The flowers are rich in nectar and are a good bee crop.

Propagating it: Seed - surface sow February/March 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 June, the young trees being planted in their final positions in late spring of the following year. The seed has a long viability.

Things to keep in mind

Citronellal, an essential oil found in most Eucalyptus species is reported to be mutagenic when used in isolation. In large doses, oil of eucalyptus, like so many essential oils has caused fatalities from intestinal irritation. Death is reported from ingestion of 4 - 24 ml of essential oils, but recoveries are also reported for the same amount. Symptoms include gastroenteric burning and irritation, nausea, vomiting, diarrhoea, oxygen deficiency, weakness, dizziness, stupor, difficult respiration, delirium, paralysis, convulsions, and death, usually due to respiratory failure.
