Acacia adunca
Acacia adunca, commonly called the Wallangarra wattle or cascade wattle, is an Australian shrub or tree in the pea family, Fabaceae. The New South Wales flora treats Acacia accola as a synonym, rather than a separate species.[1]
Appearance
Its long, narrow green phyllodes perform the role of leaves. They are usually 7–13 cm long and only 1–3 mm wide, with a small hooked tip. Bright yellow flower heads form small globes, each containing about 9–14 flowers. The seed pods are thinly leathery, generally slightly curved and 5–13 cm long.[1]
Plants can grow upright or spread outwards. The regional flora records heights of 2.5–14 metres; smaller dimensions in garden accounts are not a maximum for the species.[1]
Range and habitat
The Wallangarra wattle grows on the tablelands of southern Queensland and northern New South Wales. Its common name refers to the border town of Wallangarra.[2] In New South Wales it occurs in dry forest, woodland and shrubland, particularly around granite outcrops. The regional flowering period is usually June to October.[1]
Cultivation
An Australian National Botanic Gardens account describes abundant, sweet-scented flowers and drooping outer branches during flowering. It records successful cultivation in sunny, well-drained positions and explains that the hard seed coat needs treatment before germination, such as scarification. Pruning after flowering can encourage a spreading shrub form. [2]
