About Oxylobium robustum Joy Thomps.
Oxylobium robustum, scientifically described by Joy Thomps., is a shrub or small tree that typically reaches a maximum height of 3 m (9.8 ft). Its stems are covered in woolly yellow or white hairs. Leaves are most often arranged in whorls, and sometimes grow in opposite pairs; they range from linear to lance-shaped, measure 25โ80 mm (0.98โ3.15 in) long and 1โ3 mm (0.039โ0.118 in) wide, end in a sharp point, and have downward-curving edges. Flowers grow in racemes located in leaf axils and at the ends of branches, with lance-shaped bracts and linear bracteoles at their base. Sepals are around 7 mm (0.28 in) long, while petals are yellow-orange and 8โ12 mm (0.31โ0.47 in) long. Flowering takes place from late winter to early summer. The resulting seed pods are 7โ10 mm (0.28โ0.39 in) long, have a beaked tip, and are covered in soft hairs. This species, commonly called tree shaggy pea, grows in forest and heath habitats ranging from south-east Queensland to Newcastle in eastern New South Wales. For horticultural use, Oxylobium robustum can be propagated from scarified seed or cuttings. It grows well in moist, well-drained soils in locations with full sun or light shade.
