Found growing along water courses and roadsides, the Bush Hibiscus (Radyera farragei) has a striking looking flower that are a pink, mauve to pale purple in colour. The large trumpet like flowers have 5 petals, with 2 to 3 on very short stems that arise from the bases of the leaves.

The shrub grows between 1 to 2 metres in height and has large leaves.

The leaves are petiolate (the leaf is attached to a stem by a petiole) and sub-orbicular (nearly circular) although sometimes broad-ovate (being wider at the base). The leaf is cordate at the base (being heart shape only at the base of the leaf).

Common name
Bush Hibiscus, Desert Rose Mallow, Desert Mallow, Knobby Hibiscus.
