Eucalyptus gregsoniana - Wolgan Snow Gum

A small tree or multi-branched, slender-stemmed mallee, which is unique and unusual for a snow gum.  It has a light, open airy habit and is ideal for a sheltered garden or coastal region.  This species can be trained to maintain a single trunk, even though it is a mallee (multistemmed).

 

Botanical Name: Eucalyptus gregsoniana (syn. E. pauciflora ssp 'Nana') Family: Myrtaceae

Common Name: Wolgan Snow Gum, Mallee Snow Gum 

Status: Evergreen Tree

Origin: The Blue Mountains, Budawang Range and South of Braidwood in south-eastern New South Wales

Named gregsoniana  after Eucalyptus enthusiasts, the Gregsons, a father and son from Mount Wilson, NSW.

Our Seed Source: Alpine region of New South Wales

 

Why we like this variety:

• A truly small Eucalyptus species that will not outgrow its mature size of around 6-7m (18 feet). Short term it will form a small tree of around 12 feet and will not exceed 18ft with a light airey canopy
• If grown as a multi-stem it can be kept even smaller than 18 feet
• Good ornamental smooth silvery creamy bark
• Very well behaved and manageable specimen for small gardens and courtyards

 

E. gregsoniana has a lignotuber at the base of the trunk. This 'body', full of dormant vegetative buds, is the tree's aid to survival, assisting regeneration after a crisis event, such as a fire, a hard winter or excessive grazing (by an animal with a strong constitution and no taste buds!). The lignotuber is activated by the removal or death of the top part of the plant, whereupon it produces a mass of vigorous new shoots, which grow up to form the new tree.

Part of the pauciflora group of Eucalypts, E. gregsoniana is often classified as E. pauciflora ssp. Nana
The native habitat of  E. gregsoniana is high altitude locations, where it can be seen growing in alpine mallee groups amongst other shrubs; along ridges, on hills and flat land with free-draining soil.
