Eucalyptus debeuzevillei or to give the tree’s full name is Eucalyptus pauciflora subspecies debeuzevillei

PLUS: LIMITED OFFER – FREE ECO-MULCH MAT KIT with every tree purchased (while stocks last)

Down to the nitty gritty – Debi  (the  Jounama Snow Gum) is a member and sub-species of the pauciflora (Snow Gum) group.

A good specimen variety, it grows to form a relatively small to medium sized tree or mallee with an attractive crown and the most amazing foliage and bark.

Grow Eucalyptus debeuzevillei as a beautiful standard tree as shown in the main photograph or train it as a multi-stemmed specimen and make the most of its amazing bark detail, by acquiring one of our young multi-stemmed trees.

Debi’s are also great in containers particularly as they are so hardy.  Click here to learn more details on how to successfully grow Eucalyptus in containers.

If you follow our growing guidance notes, it takes about two full seasons to become established, before eventually shooting away strongly.

Biometrics for Eucalyptus debeuzevillei  – the Jounama Snow Gum

Shoots ‘n Leaves: Young shoots and emerging leaves on young plants are a striking translucent copper crimson with a white bloom (protective wax), which is very attractive when back lit by the sun…like stained-glass windows

Juvenile foliage – bags of attitude. Huge, boxy, almost oblong angular blue leaves of an incredibly thick leathery texture – very substantial and wind resistant.

New growth of Eucalyptus debeuzevillei is always a carmine red colour and transluscent – like stained-glass windows.

Adult foliage is of a blue/green hue maturing sometimes to glossy olive green. Leaves are often broadly lanceolate with prominent lateral veins.

Bark: Beautifully patterned bark.  Smooth, pearl grey to pure chalk white with an additional mosaic highlights of russet, cream, olive and silvery grey, which shreds in small flakes and ribbons from both the trunk and branches.

Great when under-lit at night. Excellent Winter-garden interest

Flowers: White flowers in groups of 9 to 15. Loved by honey bees.

Leaf Aroma: fruity eucalyptus, but not overwhelming because it is a snow gum – see trivia

Rate of Growth: Medium rate of growth at 1.0-1.5m per year, once established – takes a couple of years to get its roots down, so slow to take off.

Slow for a Eucalypt – still fast for an evergreen!

Height in maturity, if left unpruned:   Eucalyptus debeuzevillei could reach approximately 8-10 m, after about 15-20 years.

Easy to keep smaller by regular pruning – March 18th and end of May.   Can be grown as a bushy shrub – buy a multi-stemmed plant to achieve the bushy-shrub look.

Great in pots – visit the ‘How to Use’ tab

If pruned, it can be trained to form a bushy screening tree, a lollipop standard or a multi-stemmed bush like a species rose or coppiced Hazel tree.

Responds well to coppicing and pollarding, when done at the right time of year.

Unless you are growing for cut foliage, please refrain from voluntarily electing to prune your Eucalyptus from August through to February; it can kill it.

Hardiness: Eucalyptus debeuzevillei, the Jounama Snow Gum is the hardiest of All Eucalyptus. Excellent hardiness rating, root-system should be happy down to around -18°C, once mature.

Eucalyptus debeuzevillei has been introduced to Norway – which is impressive!

Please note, if not encouraged to root deeply by planting correctly and given subsequent cultural support, younger trees are less tolerant of frost and may suffer exposure damage at low temperatures, in the early years.

Hardiness in Eucalyptus is governed by

• provenance of seed (all our seed is sourced from the frostiest or coldest locations we can find)
• how it is grown (i.e. high nitrogen levels reduces cold tolerance),
• the age of the tree – the older your tree, the hardier it will be. Younger Eucs are more susceptible to frost damage, particularly if the preceding weather has been unseasonally warm.
• how long it has been planted in the ground. The deeper you can encourage the rooting by digging a 0.5-0.6m (2 feet) deep planting pit at the time of installation, the quicker your tree will establish and you will increase its ability to survive cold winters. See our planting notes for more details.

We’ve written a deep-dive article on how you can keep your Euc happy and help it to become more hardy as it establishes in your garden.
