Acacia melanoxylon is also known as blackwood wattle. This Acacia species is native to Tasmania and Eastern Australia. It is a fast grower and has a rather erect aspect, which explains why it is often used as a street tree.
This species is fairly frost-hardy, and is known to withstand low temperatures down to about 18-21°F (about -6°C to -8°C) and mature trees may survive even slightly lower temperatures.
Additionally, this wattle dense wood is often used for furniture in Australia.
This Acacia has both evergreen leaves and phyllodes : the leaves are bipinnate with tiny elliptic leaflets and the phyllodes are green-grey and up to 3-4 in (7.5-10 cm) long.
Flowers are yellow-cream, scented, globular and about .5 in (1.25 cm) in diameter. They are grouped in axillary clusters that are about 2-4 in (5-10 cm) long. They appear from early to late spring.
The fruit is an inedible seedpod which turns brown when ripe.
