Mimosa Overview

Acacia dealbata is a tender, open, evergreen shrub or small tree up to 10m. that produces attractive round bright yellow flower-heads. It suits urban gardens or milder south-west localities, but may need winter protection elsewhere. In Europe it is known as 'Mimosa'. It has a single trunk with smooth grey bark. Each bipinnate leaf is made up of hundreds of tiny leaflets coated in white hairs, giving the foliage a silvery cast. It will need winter protection unless situated in a frost free full sun position and flowers better in climates with a longer, drier summer. Grow in medium to light soil types with a moderate depth, which needs to be well drained with low salinity, with full sun with some shade.

Common problems with Mimosa
