Green Birdflower Overview

Crotalaria cunninghamii is a small shrub species in the Fabaceae family. This interesting plant is native to Northwest and North Central Australia. It produces stunning yellow-green, pea-like blooms which resemble flying birds, attached to the plant by their beaks. The flowers are lined with thin black lines and lead onto hard, club-shaped fruits with a velvety texture, measuring around 5cm in length. This plant tends to colonise unstable sand dune environments, growing well in coastal areas and Mulga communities. It grows to between 1-3m in height, producing woolly, hairy branches and dull green, oval-shaped, small leaves measuring around 3cm in length. Commonly known by the names Green Birdflower and Regal Birdflower. This tender plant grows well in full sun and well-draining, sandy soil.
