Acacia dealbata (= Mimosa)

Acacia dealbata, known as silver wattle or mimosa, is an evergreen tree of the Fabaceae family, native to Australia.

Characteristics
A medium sized tree 6-15 m tall with a dense, rounded crown; the trunk is smooth and silvery grey and the young shoots slightly downy. The bipinnate leaves are blue-green with a silvery sheen given by fine hairs, small but abundant, forming lush foliage. In late winter and spring it produces spherical to cylindrical clusters of intensely fragrant yellow flowers, followed by dark brown pods of no ornamental value.

Growing and care
It prefers full sun and well drained soil, ideally slightly acid, and is fairly drought tolerant once established, though regular watering helps during active growth. In some temperate and subtropical regions it can be invasive, so its spread should be kept in check.

Uses
Grown mainly as an ornamental tree in gardens and parks for its silvery foliage and scented flowers, which are also used as cut branches.
