Acacia irrorata: is a member of the Mimosaceae family and is known as the Green Wattle.
Acacia irrorata is a tall shrub to a medium tree with a maximum height of 12 metres. The leaves are bipinnate dark green. There are 6-12 pairs of pinnae or primary leaflets and 18-35 pinnules or leaflets on each pinna (the singular of pinnae). There is a gland at the base of some pairs of pinnae.
Yellow flowers are carried in globular head and appear between November and March. Sporadic flowering has been observed at other times. The pods that appear after flowering are straight and may be up to ten centimetres long.
Acacia irrorata is similar in appearance to other wattles with bipinnate foliage. The Green Wattle is unusual and useful in that the species flowers after the normal spring flowering period.
The Green Wattle could be grown as a “Spring Extender” that brings a spring feeling to the garden at other times of the year.
Acacia irrorata could also be grown in shelterbelts and windbreaks.
The Green Wattle has a wide distribution and is found along the coast, central and northern tablelands and slopes of New South Wales as well as southern Queensland.
Propagate from seed that should be treated with boiling water before sowing.
