WATTLE

Acacia deanei (Deane's wattle, green wattle) is a tree native to Australia, which is used for controlling erosion. There are two subspecies: Acacia deanei subsp. deanei and Acacia deanei subsp. paucijuga. Both subspecies are mainly 2-4 m tall and grow on plains, slopes and tablelands, often near watercourses, in gullies or on stony hillsides, and on a wide range of soil types in Eastern Australia.

This species often flowers throughout the year, especially during March to August; pods mature mainly during October to March or sometimes later. There are about 45 viable seeds per gram. Nicking or boiling the seeds in water for a minute at 100°C is required to induce germination. The seeds start to germinate in about 5 days if grown at 25°C. Acacia deanei is a fast growing, nitrogen-fixing shrub that has the potential to play a valuable role in catchment protection.

It is relatively drought and cold tolerant; its pollen has value in apiculture. This tree is known to be moderately drought tolerant but is killed by damaging fire and does not regenerate foliage afterwards. It tolerates frosts in the 0° to -5°C range or tolerates heavy frosts colder than -5°C. This tree has good ornamental attributes and is often used in the urban environment as a street or park tree.
