Description, habit, uses and attributes:
Eucalyptus glaucescens ‘Tinderry’ is an exceptionally hardy form of the species as its provenance is the extremely cold ski resort in the Australian ‘Alps’. The tree is also of good form and vigour.
Lignotuber: it has one, which is a good thing! E. glaucescens will regenerate off the lignotuber if cut down by man, beast or nature. It also produces many shoots from epicormic buds lying dormant beneath the bark higher up the tree; so E. glaucescens will respond extremely well to both coppicing and pollarding practices.
How to use in the landscape and/or garden:
ow to grow or train it to get the best out of it:
Good Specimen Tree for the wider landscape, arboretum, avenue and for the medium/larger garden: E. glaucescens grows into a very handsome tree
Growing a full sized standard: planting the tree and running away is an option, but it won’t necessarily give you the best results. For information on how to do it properly see our ‘Help’ pages here -
Growing shrub-onna-stick clipped standard: this is an opportunity to grow a Eucalyptus in a confined space and control its overall size. You can produce a small tree on a trunk with a height of anywhere between 2.4m (8ft) and 4m (12ft)
E. glaucescens can be successfully grown in this manner with pruning to shape on March 19th and again during the first/second week in June
Growing a multi-stemmed bush or tree. E. glaucescens responds well to coppicing and readily produces a multi-stemmed specimen. Annual pruning on March 19th will help to keep this species compact and bushy.
Why would you want to do this?
- a tree with more body or ‘mass’ of branches and foliage for screening purposes. Once grown back up to its full potential, it will now have several main trunks
- an attractive multi-stemmed architectural tree, especially if it has exceptional bark
- to control height, whereby your Euc can be usefully maintained anywhere between 2.4m (8ft) and 7m (20ft), but genetically it will want to grow taller if ignored.
Floral Art: E. glaucescens is grown for its intermediate foliage, rather than its juvenile form.
For information on how to grow cut foliage, see our ‘Help’ pages here
Firewood Production: E. glaucescens is our number one species for Biomass and Firewood logs. Vigorous, high yielding and the only one of the Eucs to be reliably vermin-proof.

- Good shade tree for livestock to stand under. Eucalyptus provide a cool environment for horses, cattle, llamas, sheep to shelter from the sun on hot days, as the mass evaporation of water through the leaves creates a cool shady canopy beneath. Also, I have been told that the eucalyptol in the leaves deters flies
- Bees. E. glaucescens produces useful flowers providing foraging for honey-bees and other pollinating insects
- Habitat creation and Game Cover: E. glaucescens lends itself to providing good trouble-free habitat creation for wildlife and game cover, when multi-stemmed bushes are planted in groups.
Birds enjoy roosting in Eucalyptus trees and Pheasants like rootling around underneath them.
- Chickens: The shredded foliage of E. glaucescens is excellent at keeping Chicken nest boxes and hen houses free of red mites, which detest the presence of Eucalyptol. I used to line our Chicken boxes with shredded leaves, strew the floor and pile up the spindly branches for the chickens to make nests. It was all great till the foxes moved into the next field.
- Growing on the Coast We have no experience of growing E. glaucescens in a coastal environment, but have seen plenty of gunnii group Eucs grown successfully in site of the sea in Cornwall. I suspect it may do well in coastal districts, when grown a mile or two inland of the sea, but this needs trialling. Do get in touch if you are giving this a go and let us know how you get on.
- Drying up wet soils. E. glaucescens is very at home in moisture retentive, but not permanently boggy soils. Our Tingiringi gums have certainly thrived in our swampy, alkaline, yellow clay, putting on a great deal of weight over the past couple of years and forming handsome trees; and the surrounding ground has definitely dried up.
- Tolerant of cold and exposed growing environments inland E. glaucescens will grow in open fields and pasture; it does not require a sheltered position. No grass, no weeds and a thick bark chip mulch, to a depth of 150 mm (6 inches) are essential to assist with good establishment
Pot Culture outdoors: E. glaucescens can be successfully grown as a multi-stemmed shrub in a large container provided you are prepared to pot on at the recommended intervals and to supply it with sufficient water and food during the growing season. If not watered enough, it becomes thin and spindly, dropping its lower leaves. Guthega is a very vigorous form and needs to be grown in a large air-pot container to be successful. We recommend you pot into a 45 litre very quickly for the duration of 2 to 3 years and from there, into a container that is over 100 litres. Pruning on March 19th and again in June is essential every year, to keep it bushy. Single stemmed containerised E. glaucescens are prone to falling over in high winds and can be challenging to manage, if not held in position; they are better planted in the ground.

Shoots ‘n Leaves: Young shoots - silvery blue often with pink bits
Juvenile foliage: rounded young leaves are amazingly silver in the spring and are densely packed around the young stems, transitioning to oval, intermediate foliage
Adult foliage: typical lanceolate shape, in glossy green to a jade blue-green; often shimmers silver in the breeze.
Bark: Young silvery green bark gives way to stunningly beautiful peeling chalk-white bark on the upper part of the tree; shredding in ribbons, revealing a smooth under layer in a rainbow of colours of coffee, pewter, orange, green, custard and salmon pink. Mature bark on the lower part of the tree is often fibrous and coffee coloured.
Flowers: Cream coloured flowers, in groups of 3 - deliciously sweetly fragrant
Leaf Aroma: very strong, warm fruity aroma, high in eucalyptol.
Rate of Growth: Fast 1.5-2.0 metres per year
Height in maturity, if left unpruned: Tall If left to grow unpruned, this Euc can achieve a great height of 12 to 20 metres in the medium term either as a single trunk or multi-trunk, depending on the soil type and degree of exposure. Long term into maturity and under optimal growing conditions, E. glaucescens could reach 40-50m. Given plenty of access to moisture during the summer, it can produce a dense bushy crown. Deprived of moisture during the summer months and it will develop a very open, minimalist crown.
Hardiness: very hardy, tolerating down to around -14 °C to -16 °C mark, once mature.
Hardiness in Eucalyptus is governed by provenance of seed, how it is grown (i.e. high nitrogen levels reduces cold tolerance), age of the tree - the older your tree, the hardier it will be. Younger Eucs are more susceptible to frost damage.
Planting position and soil preference:
Needs full sun and open sky above. Happy in a wide range of soils; best on acid to neutral of average to good fertility. Tolerates poorly drained soil; grows well on our horrible yellow swampy wet clay soil at Grafton Nursery. Good in exposed locations.
To encourage deep rooting and therefore good stability, prepare a deep planting pit as per our instructions. If planting a large number for firewood or cut foliage, subsoiling may be a good practice to follow, especially if pastureland has previously been used by livestock.
For the best results, follow our planting and aftercare watering instructions; issued with every order.
Make life easier for you and your new tree: Plant with the mycorrhizal fungi product Rootgrow. Eucalyptus in particular have a special, lifelong relationship with their root fungi, which actively transport food and water directly into the tree roots, helping your new Euc establish faster and more efficiently, particularly in challenging types of soil.
Meaning of the name:
From the Latin glaucescens referring to the white wax that coats the branchlets, flower buds and fruits.
