The familiar mimosa of the florist which is imported from the South of France, is Acacia dealbata (silver wattle). It will often survive all but the hardest winters outdoors if planted against a south or south-west wall, especially in favoured localities, such as Cornwall and the Scilly Isles.

Most species are of Australian origin, and do best in a sandy loam. Acacia Baileyana (the Cootamunda wattle) has distinct glaucous grey foliage and is nearly hardy.

Acacias can be propagated by cuttings pulled off with a heel of older wood in July.

The so-called rose acacia, the common acacia etc. belong to the genus Robinia .
