Eucalyptus perriniana (common name: spinning gum)
Propagation: Seed - surface sow February/March in a sunny position in a greenhouse[1][2][3]. Species that come from high altitudes appreciate 6 - 8 weeks cold stratification at 2°c[4]. 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[4].
Cultivation: Prefers a sunny position in a moderately fertile well-drained moisture retentive circum-neutral soil[4]. Tolerates poor soils, especially those low in mineral elements[4]. Tolerates dry soils and also drought once it is established[4].
A fairly hardy species, it tolerates long periods down to -14°c and short periods as low as -18°c[5][4].
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[4].
A tree at Alice Holt forest in Hampshire was 15 metres tall in 1985[1].
Trees respond well to coppicing[6][1].
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[7]. They strongly resent root disturbance and should be container grown before planting out into their permanent position[1].
Eucalyptus monocultures are an environmental disaster, they are voracious, allelopathic and encourage the worst possible attitudes to land use and conservation[4].
The plant has juvenile foliage which is quite different from the adult leaves[8].
The flowers are rich in nectar and are a good bee crop[4].
Range: Australia - New South Wales, Tasmania, Victoria.
Habitat: Wet hollows on poor mudstone soils to 1800 metres[9].
Usage: The leaves yield up to 1% essential oil[10].
Pollinators: Bees
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
In Leaf: Evergreen
Flower Type: Hermaphrodite
Known Hazards: Citronellal, an essential oil found in most Eucalyptus species is reported to be mutagenic when used in isolation[11].
In large doses, oil of eucalyptus, like so many essential oils has caused fatalities from intestinal irritation[11]. Death is reporte
Also Known As: E. gunnii montana.
