Tetratheca.JPG (38096 bytes)Tetratheca thymifolia: is a member of the Tremendraceae family but in the future may finish up in the Elaeocarpaceae family. Regardless of its family connections, Tetratheca thymifolia is a beautiful, long-flowering small shrub.
There is some disagreement about the number of species in the genus. One publication says there are 20 whilst another gives a figure of 40 species. All are native to Australia .
Tetratheca thymifolia is known as the Black-eyed Susan. This is a confusing common name because it also refers to Thunbergia alata, an exotic vine that has become an environmental weed in parts of Australia .
Tetratheca thymifolia is a mounded, suckering shrub with small leaves carried in whorls of three or four around the stem. Deep pink, bell-like flowers cover the stems for many months. The flowers have a black centre that gives rise to the common name. There is also a white-flowered form.
Tetratheca thymifolia occurs in eastern Australia from Queensland to Victoria . We have observed the species growing in a reserve on the Southern Tablelands of New South Wales. In some areas it was the dominant small shrub that carpeted the ground with pink flowers.
Tetratheca thymifolia could be cultivated in rockeries, native cottage gardens or as a container plant.
Tetratheca thymifolia will hybridise with another species (Tetratheca rubioides) where they occur in the same area. Propagate from cuttings.
