Description

The plants have an erect habit and can grow to 2 to 3 metres high, although plants in the range of 0.5 to 1 metre tall are more commonly observed. The branches are stiff and have small leaves with prickly, pointed apices that are 8 to 16 mm long. The flowers, which mainly occur between late autumn and early spring are white, pink or red in colour and appear in dense clusters along the stems. They are 1–2 cm long and are narrow and tubular with five indentations on the base.
Different colour forms are often observed growing near to each other. Seed capsules are 3.3–3.5 mm long.

Symbolism

At a meeting of representatives of government and other bodies in 1951, the pink form of the Common Heath, the "Pink Heath", was adopted as the official floral emblem for the state of Victoria in 1958. Victoria was the first Australian state to adopt a floral emblem. The proclamation, was as follows:
An Australian stamp issue of state floral emblems was issued in 1968, including the Pink Heath which was featured on the 13c stamp. The Pink Heath was also depicted on the VicRoads

Taxonomy

The type specimen of Common Heath was collected in 1793 by French botanist Jacques Labillardière

 It was described by Labillardiere in 1805 who gave the species its current name Epacris impressa. The Latin specific epithet impressa (meaning "impressed" or "indented") alludes to the indentations on the floral tube.

Cultivation

cultivation.

Plants grow best in a moist but well drained, acidic soil. They may be grown in coastal gardens in a sheltered position. They can be short-lived and are difficult to transplant. Propagation both by seed and cuttings is difficult, reducing potential production by plant nuseries. The most satisfactory results from cuttings can be achieved by using tip growth taken six weeks after the cessation of flowering and kept under a fogging system for twenty weeks.
