prickly box (Bursaria spinosa)
The best features of prickly box are its masses of cream-coloured fragrant flowers followed by attractive bunches of brown seed capsules - both lasting on the plant for many months.
Aboriginal people found its timber made good waddies (clubs). They also sucked nectar from its flowers.
Early European settlers found the leaves contained an oil which helped prevent sunburn.
Its fibrous roots are good for erosion control.
'Bursaria' comes from the Latin word 'bursa', which means purse - referring to the seed capsules which are shaped like a pouch. 'Spinosa' comes from the Latin word 'spinosus' - referring to the spines on the young branches.
Prickly box scented cream flowers are produced mainly from October to February, but can be found on the plant year-round.
Prickly box is an important food plant for many insects, including beetles, butterflies, moths, caterpillars and ants. Jewel beetle larvae can be found living in tunnels in dead and dying branches. Bushier forms of the plant also provide a safe haven for small birds and bandicoots.
