Plants in the genus Correa are shrubs to small trees with simple leaves arranged in opposite pairs. The flowers are bisexual and are arranged in cymes in leaf axils or on the ends of branchlets. The four sepals are fused, at least at the base, forming a cup-shaped calyx. The four petals are usually fused for most of their length to form a tubular corolla and the eight stamens are free from each other. There are four carpels fused at the base, the four styles are fused and the stigma is similar to the style. The follicles contain up to two dull brown seed that are released explosively.[2][3][4]
The genus Correa was first formally described in 1798 by Henry Cranke Andrews in The Botanist's Repository for New, and Rare Plants and the first species he described was Correa alba.[5][6] The genus is named after the Portuguese botanist José Correia da Serra (1750–1823), known as Abbé Correa.[7]
The following is a list of species, subspecies and varieties of Correa accepted by the Australian Plant Census as at July 2020:[8]
Many Correa hybrids are grown in Australian gardens. They are generally easy to grow. Correa alba and C. glabra varieties are the hardiest withstanding heavy frost and severe droughts. They can be grown in either full sun or a partly shaded spot in the garden. Correa glabra varieties have fragrant leaves. Correa lawrenceana is the largest of the correas. These need to be grown in the shade and do best in an understorey habitat. They are highly attractive to birds for both nectar and nest sites and are ideally planted in a thicket. Correa pulchella varieties produce the most beautiful coloured bells ranging from pale pink to deep orange to carmine. They need to be grown in part shade and watered regularly. Correa reflexa varieties range in colour from green to deep red. They also need to be grown in a partly shaded position and watered regularly. Some Correa species, such as C. eburnea and C. calycina, are endangered and difficult to obtain in the nursery trade.[citation needed]
There are also hundreds of named cultivars, many of which have been registered with the Australian Cultivar Registration Authority (ACRA).
