Correa alba, commonly known as white correa, is a shrub endemic to Australia. It grows to 1.5 metres in height, has reddish-brown hairy new growth. The leaves are near circular to ovate and have a round or cuneate base and a rounded tip. They are 1.5 to 3.5 cm long 1 to 2.7 cm wide with a hairless or (nearly hairless) upper surface and tomentose lower surface. The white or occasionally light pink four-petalled flowers usually appear between mid autumn and early winter (April to June in Australia).[1]
The species was first formally described by Henry Charles Andrews in 1798.[2] There are currently two recognised varieties:
- Correa alba Andrews var. alba
- Correa alba var. pannosa Paul G.Wilson - Velvet White Correa.[3] Occurs on the south-west coast of Victoria and in the region near Encounter Bay in South Australia.[4]
Distribution and habitat
The species occurs on low-nutrient soils,[5] in sandy or rocky areas in coastal areas of south-eastern Australia south of Port Stephens,[1] particularly headlands and coastal heathlands. It can grow in areas where it is sprayed with salt water.[5] It is commonly associated with such heathland plants as coastal rosemary (Westringia fruticosa), bracelet honey myrtle (Melaleuca armillaris) and common aotus (Aotus ericoides), and dune plants such as Sydney golden wattle (Acacia longifolia).[5]
Ecology
Wombats have been known to eat the leaves and roots.[5]
Cultivation
Correa alba is a hardy species in well-drained situations that withstands coastal exposure. A position in full sun is best for flowering, but it can also be grown in part shade. It may be used to create an informal hedge or as a container plant.[6]
