Podalyria myrtillifolia or commonly the purple butterfly is a shrub that grows to 2 m. It has simple, alternate leaves that are ovate to obovate in shape. The leaves are covered in silky hairs on both surfaces.
The pink flowers with a little white in the centre, shaped like those of peas are subtended by lanceolate bracts. Flowers are about 1,3 cm long. Flowering happens in winter and early spring.
The long-haired, bulging fruit pods contrast against the leaves that have short hairs (Manning, 2007).
