Callistachys lanceolata, commonly known as the wonnich, native willow,[3] or greenbush[4] is the sole species in the genus Callistachys. It is a species of erect shrub or small tree that is native to the south-west of Western Australia and is naturalised in some in other Australian states.
Description
Callistachys lanceolata is an erect evergreen tree or shrub that typically grows to a height of with a height of 1.5–7 m (4 ft 11 in–23 ft 0 in) and has silky-hairy young stems.[5] The plant has conspicuous and attractive inflorescence composed of racemes with yellow flowers. The plant flowers through the spring time between the months of September to January.[6] The leaves of the plant are leathery and are arranged in whorls, most typically with three leaves per whorl. The leaves are generally regular in shape between 40 millimetres (2 in) to 170 millimetres (7 in) in length and 4 millimetres (0 in) to 30 millimetres (1 in) in width and have pointed tips.[7]
Distribution and habitat
Callistachys lanceolata occurs in the South West corner and South Coast of Western Australia. It grows well in sandy soils in areas that are damp, particularly along watercourses, swamps and culverts.[5]
Taxonomy
The genus Callistachys[8] and Callistachys lanceolata[9] were first formally described in 1805 by Étienne Pierre Ventenat in his book, Jardin de la Malmaison.[10]
Use in horticulture
Seeds can be collected from the plant but the pods the seeds are found in should be left to dry on the plant before they are broken open. The seeds should be scarified before sowing.[11]
