Description

The plant grows to about 1 metre in diameter and has leaves that are oval in shape with a dark green upper surface and a silky undersurface.[1] The flowers appear predominantly between July and October in the species' native range. These are orange-red[1] with a standard that has recurved margins and yellow markings[2]

Distribution and habitat

The species occurs in open Jarrah (Eucalyptus marginata) forest near Mount Barker and Cranbrook, with an outlying population in Fitzgerald River National Park.[2]

Cultivation

The species has been popular in cultivation for many years, often distributed under the incorrect name of Brachysema latifolium.[3] The plant may be used as a groundcover on embankments or in large containers or hanging baskets.[1] It prefers light shade and good drainage, and is somewhat frost-tolerant.[1]
