Distribution en:

Description en: Genus of at least 1,100 species of deciduous and evergreen trees, shrubs, and climbers, cultivated mainly for their flowers, and sometimes foliage. Acacias are found in tropical to warm-temperate regions of Central and South America, Kenya, southern Africa, Polynesia, and Australia. Leaves are alternate and 1- or 2-pinnate, or may be reduced to flattened leaf-stalks known as phyllodes, mostly lance-shaped to ovate and entire. Tiny flowers, often sweetly scented, with 4 or 5 minute petals and long stamens, form either spherical heads, 5-10mm (1/4-1/2in) across, in racemes or panicles, or are borne in short, cylindrical spikes, l-8cm (1/2-3in) long. They are usually produced in winter or spring. These are followed by varyingly shaped seed pods, mostly green, sometimes flushed with red or purple. In frost-prone areas, grow tender species in a cool or cold greenhouse and half-hardy species against a warm wall outdoors; in frost-free areas, grow in a border, or as specimen plants.

Hardiness en: Half hardy to frost tender.
