About Chorizema cordatum Lindl.
Chorizema cordatum, commonly known as heart-leaf flame pea, is an erect, scrambling or climbing shrub that typically reaches 1 metre (3 feet 3 inches) in height and 1.5 metres (4 feet 11 inches) in width. Its leaves are heart-shaped, between 30 and 50 millimetres (1.2 to 2.0 inches) long, with a stipule at the base of the petiole, and often have wavy, toothed or lobed edges. Its flowers are arranged in racemes up to 120 millimetres (4.7 inches) long, growing at the ends of branches or in leaf axils. Individual flowers are 10 to 12 millimetres (0.39 to 0.47 inches) wide, and come in various combinations of yellow, orange, red, and pink. Flowering occurs from July to December. Heart-leaf flame pea grows in forest, on rocky outcrops, along watercourses, and on winter-wet flats in the Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain, and Warren bioregions of south-western Western Australia. This species can be grown as a garden plant, and grows well in other parts of Australia, including Sydney on the opposite side of the continent. It grows best in summers with lower humidity. Since it does not tolerate freezing temperatures, it requires glass protection when grown in cooler regions. It can be propagated easily from seed, and cuttings root easily.
