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.
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 in length. Flowering happens in winter and early spring.
The long-haired, bulging fruit pods contrast against the leaves that have short hairs (Manning, 2007).
