This South African shrub to 2 m high is widely naturalised across southern Australia and has become invasive in coastal areas. These shrubs are most readily recognised by their mauve-purple, pea-shaped flowers produced throughout most of the year, predominantly during spring. Flowers develop two-celled flattened seed capsules that ripen from green to papery brown. Whilst the plainer form with greenish lower petals is frequently observed as weedy, the showier cultivar 'Grandiflora' with larger flowers and purple lower petals has also been observed readily spreading from plantings.

These small to medium sized native shrubs from Western Australia reach 1.5–2 m high with linear, narrow highly aromatic leaves up to 4 cm long. Small flowers occur profusely in spring through to summer and darken as they age. A highly recommended cut flower, they can be picked in bud or at the full flowering stage. Numerous colour forms are available including; white 'Alba'; purple 'Purple Pride' red to white 'y Sweet Sixteen', and the doubl flowering pink 'Raspberry Ripple'.

This less invasive form of Polygala is an ideal alternative. It is a delightful compact small shrub that grows 1.5 m high by 1 m wide with striking purple pea flowers for most of the year. Grows best in full-sun to partshade in a well drained position.

This compact, dense shrub grows 0.9–2.4 m high by 0.9– 3.0 m wide. Tubular flowers appear in the leaf axis from winter through to spring. Flower colour is variable and may be pink, mauve, red, orange or yellow, often with a pale, spotted throat. It grows well in full-sun or part-shade and is mildly frost tolerant. It makes a great screening or hedge plant and responds well to hard pruning. Bird attracting.
