Acacia leprosa ‘Scarlet Blaze’

The Australian Botanic Garden, Mount Annan - September

Common name Acacia 'Scarlet Blaze'
Scientific name Acacia leprosa ‘Scarlet Blaze’
Family  Faboideae - Mimosoideae

Genus: From the Greek akakia, the name of Acacia arabica, of tropical Africa and Western Asia (from akis, a sharp point, as this is a spiny species).

Species: Having a scurfy appearance, 'spotted like a leper'.

Distribution Originally one red-flowering plant in the Black Range State Forest north-east of Melbourne, Victoria. This plant is now dead.
Native habitat Woodland.
Description A medium shrub to small tree, a weeping form with large phyllodes and red flowers.
Flowering/fruiting Flowers in late winter/early spring at the Australian Botanic Garden, Mount Annan.


You’ll find this plant in the Wattle Garden in Beds 126, 133 and 141.


This is an oddity which you probably won’t easily find anywhere else. It’s the world’s only red-flowering wattle. As you probably know, wattles usually range in colour from white through cream to light and then bright yellow (with one mauve species from northern Australia and a pink species in Tasmania). But ‘Scarlet Blaze’ is a colour mutant of the normally yellow-flowering Acacia leprosa, the cinnamon wattle. Victoria selected this mutation as its state flower in celebration of the Bicentenary of Federation in 2001 and the Royal Botanic Gardens Melbourne has released it commercially. 

It prefers a well-drained, moist soil in full sun to dappled shade and is quite drought tolerant, requiring only occasional deep watering once established.
