Epacris impressa, also known as common heath, is a plant of the heath family, Ericaceae, that is native to southeast Australia (the states of Victoria, Tasmania, South Australia and New South Wales). French botanist Jacques Labillardière collected the species in 1793 and described it in 1805. Four forms have been identified, but no subspecies are recognised. Growing in heathland, shrubland or open forest, it is generally a small shrub around 0.5 to 1 m (1 ft 8 in to 3 ft 3 in) tall, with small stiff leaves. The red, pink or white tube-like flowers appear from late autumn to early spring. Honeyeaters, particularly the eastern spinebill, feed upon the nectar of the flowers. It regenerates after bushfire by seed or by resprouting.
A highly regarded garden plant, the common heath was first cultivated in England in 1825; over seventy named cultivars have been developed, most of which have now vanished. A pink-flowered form, often referred to as "pink heath", is the floral emblem of the state of Victoria. Epacris impressa has proven a difficult plant to propagate reliably, which has limited its use in horticulture and revegetation. It grows best in well-drained but moist soil in a semishaded position.
Epacris impressa grows as a woody shrub with an erect habit, sometimes reaching 2 to 3 m (6 ft 7 in to 9 ft 10 in) in height although plants in the range of 0.5 to 1 m (1 ft 8 in to 3 ft 3 in) tall are more commonly observed. The branches are stiff and have small leaves with prickly, pointed apices that are 8–16 mm (3⁄8–5⁄8 in) long. The flowers mainly occur between late autumn and early spring, arising in dense and sometimes pendulous clusters along the stems. White, pink or red in colour, they are 1–2 cm (3⁄8–3⁄4 in) and are narrow and tubular with five indentations on the base. The corolla of the flower is formed by five petals, fused at the base to form a tubelike structure, with the free petal ends forming five lobes at the apex. There are five whorled sepals at the base of the corolla. Within the corolla is a central style that persists through development of the fruit. The style connects the stigma at the apex and ovary at the base, where the nectar is also located. Different colour forms are often observed growing near each other. The fruit is a 5-locule capsule that is about 3.5 mm (1⁄8 in) in diameter. It is globular in shape, sometimes with one end flattened. Initially green, it dries and splits, releasing numerous tiny seeds.
