 native to Victoria, New South Wales and Queensland in eastern Australia. Its blue-purple flowers appear in spring and early summer (September to December), and it is pollinated by insects such as butterflies and bees. Adapting readily to cultivation, Dampiera purpurea is grown as a garden plant in Australia.

Description

Dampiera purpurea is an erect multi-stemmed plant to 1 m (4 ft) high with obovate to elliptic leaves which are 0.9 to 6 cm (0.4-2.4 in) long and 0.5 to 4.2 cm (0.2-1.7 in) wide. The stems and undersides of leaves are covered in fine hair and rough in texture, while the leaves are bare of hair when mature. The flowers are mainly produced between August and January in the species native range. Three to five flowers arise each on groups of two to nine flower-bearing branches. Reaching 2.5 cm (1 in) in diameter, they are generally blue-purple in colour with yellow centres, though pink and white flowers have been recorded.

Ecology

Dampiera purpurea is killed by bushfire, with new shoots arising from ground level. These can then flower in ten months, peaking around two to three years after a fire. It also regenerates by seed from fire.

Cultivation

Dampiera purpurea can be grown in cool to subtropical climates. It is a variable species, reflected by the many forms in cultivation. Preferring a lightly shaded position, it also adapts to full sun and has some frost tolerance.
It is adaptable to most reasonably drained soils and will withstand dry periods once established, though best results are obtained though a steady supply of moisture in spring and summer. It can be more vigorous in heavier soils. A light pruning after flowering keeps plants in shape. Plants can be propagated by cuttings or division.
