What is Blue Mallee Eucalyptus?

Blue Mallee AKA Eucalyptus polybractea, is commonly known as the blue-leaved mallee or simply blue mallee, It is a species of mallee that is endemic to south-eastern Australia. It has a rough, fibrous or flaky bark on the lower part of the trunk, smooth greyish or brownish bark above, lance-shaped adult leaves, flower buds in groups of between seven and eleven, white flowers and cup-shaped or barrel-shaped fruit.

Blue Mallee occurs in 2 distinct areas. One is near Bendigo in Victoria. The other consists of extensive stands around the West Wyalong region, 400 kilometres west of Sydney. The area is semi arid Mallee and woodland country.

Mallee trees have a massive and extensive root ball system that lies just under the surface of the soil. This acts as a defensive system for fire and  as a reservoir for moisture and nutrients. This is essential for the tree in what is a very low nutrient soil system.

Blue Mallee trees are typically shorter trees and grow to around 8 metres.

The tree tends to flower in autumn and early winter. Mallee trees have multiple stems, with some suggesting the tree is upside down in the ground.
