Eucalyptus gunnii - Cider Gum
At present, the most commonly grown Eucalyptus species in the UK, but we are aiming to change this! An extremely hardy and versatile species, which can be grown as a large specimen tree or a bushy shrub.
Also check out E. glaucescens for a handsome tree. Call us on 07307 413 052 for assistance in choosing your Eucalyptus.
Why we like this variety:-
- Easy to grow - good all rounder - versatile, reliable and hardy variety
- Produces a beautiful specimen tree, garden shrub or potted plant
- Can be used to grow your own firewood
- Excellent for cut foliage for flower arranging
Check out E. gunnii's more dwarf cousin Eucalyptus gunnii 'Azura' for a tree that grows to half the size of E. gunnii. Also look at E. archeri - it has good screening ability, same fast growing gunnii type behaviour but with more refined habits and smaller finished height. Finally look atE. glaucescens which is a more handsome tree than E. gunnii and E. urnigera for a shorter, slim line profile with nice bark.
Botanical Name: Eucalyptus gunnii Family: Myrtaceae
Common Name: Cider Gum
Status: Evergreen Tree
Origin: a species of Eucalyptus endemic to Tasmania, occurring on the plains and slopes of the central plateaux to around 1100 metres, with isolated occurrences south of Hobart
Origin of the name Cider Gum: this variety produces a sweet sap which can be tapped in a similar way to maple syrup. We have read that the Aboriginal people of Australia ferment this liquid to produce a cider-like alcoholic beverage. Yum! Could this be a truly medicinal, alcoholic drink? If any one out there trys this, let me know!
Processing, shipping & dispatch
A cautionary note! We get a lot of questions about "Eucalyptus that have grown too tall" so...
E. gunnii grows very tall, very quickly, if unpruned and not managed (25m / 75ft or more). Although popular in garden centres and easy to find online, there are better options for a small domestic garden.
Of course, you can always try a E.gunnii if you'd like to grow it in a small garden and keep it shorter; read our section on training and pruning - it responds really well to pruning as a shrub, and is an excellent choice for DIY cut foliage or a commercial foliage grower.
We suggest looking for smaller growing Eucalyptus in our shop; there are lots of green Eucalyptus species as well as blue-grey but less E.gunnii-like Eucalyptus species to choose from that don't get too tall!
Suggestions for a good E.gunnii replacement;
E. gunnii 'France Bleu' - silvery blue leaves. Small. Recommended you keep as a pruned shrub,
E. gunnii 'Azura' - very shiny silver-blue leaves, a small Eucalyptus tree, also good as a pruned shrub, can train as shrub on-a-stick or small tree, much prettier than standard gunnii,
or E. archeri - almost identical leaf to gunnii, a medium Eucalyptus tree, excellent hedge screen and pruned shrub, can train as shrub on-a-stick.

Description, habit, uses and attributes:
At present, E gunnii is the most commonly grown species in the UK, but we are aiming to change this! An extremely hardy and versatile variety, which grows exceptionally tall, but can be grown as a specimen tree or a bushy shrub. Like most Eucalypts, as the plant matures the juvenile foliage is lost in favour of the elongated adult leaves, so keep it pruned if you want to maintain those lovely round leaves for flower arranging, a more manageable tree or bushy garden shrub.
If pruned hard/coppiced or cut down by frost, it regenerates well from its lignotuber (at the base of the trunk). The re-growth is similar in habit to a coppiced hazel (Corulus avellana) or red stemmed dogwood Cornus sibirica
Grown as a tall screen: We established a very effective screen of E gunnii at our nursery in April 2012, 3 litre plants grew from 1m tall when planted, to 3.6m (around 12ft) by January 2014. We have just pruned them down to 2.4m (8ft)
If grown in a large pot it makes a good evergreen patio tree or conservatory plant, but when too large for the container, it is best turned into firewood rather than planted out in the garden, unless grown in an air-pot.
The appearance of bark and foliage is variable across the species, but it can generally be relied upon to grow rapidly into a medium to large evergreen tree with a short massive bole and spreading crown.
E. gunnii is one of the forestry trees grown for paper production, as well as biomass for fueling power stations and automated industrial and larger domestic boilers.
Growing E gunnii for domestic firewood production:
as you can see from this page, it is a vigorous species, adapted to growing on a wide range of soil types. If grown for firewood, it will produce a strong trunk after about 5-8 years of growth (you can leave it for a couple more years if desired), which can be felled almost to ground level in the Spring. Log immediately to the size you require for your log burner and leave to season in a dry environment/log store. The logs will be ready to use after 6 months. No need to re-plant: the stump will regenerate new shoots a few months after felling. By July, you should have many young shoots sprouting from the lignotuber; too many infact to mature into viable trunks fat enough for logs. It is best to thin these shoots out, so that you have around 5-7 robust stems per stump. These will then grow over the next 5 years or so, to produce a log typically about 4-5 inches (100-125mm) in diameter. Once the trunks are of acceptable thickness, fell again to ground level and repeat the process.
Shoots 'n Leaves: Young shoots are glaucous.
Juvenile leaves are round and of a most striking waxy grey-green and blue-green colour.
Adult foliage elegant, more elongated in rich grey-green and blue-green
Bark: Smooth bark in grey, cream, green or sometimes pinky brown, flaking off in large pieces to reveal new bark in shades of yellow/green or creamy grey.
Flowers: fluffy white flowers are produced in January/February in the UK
Leaf Aroma: strong fruity, typical Eucalyptus aroma. The oil is often extracted for aromatherapy and medicinal use.
Rate of Growth: Fast at around 1.5-2.0 metres per year.
Height in maturity, if left unpruned: approx. 25 m, taller if they achieve a great age. Can be kept smaller by pruning.
Hardiness: very hardy, tolerating down to -14 to -16°C on a regular basis and down to -18 °C for brief periods. Hardiness improves with age; young trees are more susceptible to frost damage than their adult counterparts.
Planting Position and Soil Preference: Very tolerant of a wide range of growing conditions, including boggy soils, those that are intermittently waterlogged/prone to flooding, as well as normal to dry soils and those of poor/low fertility. Enjoys full sun in an open position with no shade overhead and a moderately fertile neutral-acid soil. Although our E. gunnii grow exceptionally well on our terrible winter-waterlogged / summer-arid, alkaline clay ground.
