The Manna Gum
Also known as the Manna Gum, Eucalyptus viminalis is classified into three different sub species with the main differences being in final height and size as well as soil tolerance.
Found from New South Wales through Victoria to south Australia, as well as in Tasmania the tree also carries common names of ‘Ribbon Gum and ‘White Gum’. Growth habit will vary from a tall upright tree to shorter spreading tree depending on sub species, soil and climate.
Eucalyptus viminalis ssp. viminalis is one of the tallest of all of the Eucalypts and its main commercial use is in timber production with the timber being valued for general construction work with some use as flooring and in furniture.
All species are very attractive to birds and bees, this is a tree that is valued for honey production. It is also a source of food for the Koala.
All species find uses as a large shade tree and are also suited create shelter belts on rural properties.
Eucalyptus viminalis ssp cygnetensis and Eucalyptus viminalis ssp. pryoriana have seen increasing use in coastal areas where they cope well with the sandy soils and general coastal conditions.
Growing Conditions and Planting
Manna Gums thrive in full sun. While they reach their maximum growth potential in humus-rich, moist soils, they are highly adaptable and will grow in poorer conditions, though usually at a slower pace and with a smaller final stature.
When planting, ensure you have allocated enough space for the eventual canopy spread, which can reach 10 metres or more.
Pruning and Maintenance
Generally, the Manna Gum requires very little maintenance once established. As a large tree, pruning is usually limited to removing deadwood or ensuring clearance around structures. In rural settings, allow the tree to reach its natural shape to best showcase its iconic ribbon-like bark.
Subspecies and Varieties
The genus is split into several key subspecies, each offering different physical traits:
- E. viminalis ssp. viminalis: The “giant” of the group, this subspecies can reach heights of 50 metres. It is widely used in commercial timber production.
- E. viminalis ssp. cygnetensis: A smaller variety reaching roughly 10 metres, noted for its excellent performance in sandy soils.
- E. viminalis ssp. pryoriana: Also known as the rough-barked gum, this subspecies grows to around 15 metres. It is native to the Victorian coastline and is particularly drought and frost-tolerant.
Landscaping Uses and Companion Plants
Eucalyptus viminalis is best utilized as a large-scale shade tree or as part of a shelter belt on rural properties. Their graceful, slightly weeping habit makes them a beautiful addition to larger parks and expansive gardens.
- Wildlife Design: If you want to attract wildlife, this tree is a top choice. Koalas favor the foliage, and the nectar-rich flowers draw a variety of native birds and bees.
- Companion Planting: In a rural or native garden setting, pair these trees with hardy native grasses like Themeda triandra (Kangaroo Grass) or structural shrubs like Acacia species, which thrive in similar sun-drenched, open environments.
