About

Eucalyptus youngiana, commonly known as large-fruited mallee, Ooldea mallee and yarldarlba, is a species of mallee, less commonly a tree, that is native to arid and semi-arid areas of southern Western Australia and South Australia. It has rough, fibrous bark on some or all of the trunk, smooth bark above, lance-shaped adult leaves, flower buds in groups of three, red, pink or bright yellow flowers and short, broad, conical fruit.

Where it grows

The large-fruited mallee grows in sandy soil on flat country, often associated with Triodia species. It occurs throughout arid and semi-arid areas from north of Kalgoorlie in Western Australia through the Great Victoria Desert to Tarcoola and Bulgunnia Station in South Australia.
