Avena fatua
wild oat
An annual, clump forming grass that typically grows upright with an erect, tufted habit. It’s slender, arching stems can reach heights of up to 1.5m with a spread to around 50cm. The leaves are linear, flat, and rough-textured, typically blue-green to grey-green in colour, reaching lengths of up to 30cm. The leaf blades have a characteristic rough feel due to fine hairs on their surface. It produces distinctive, loose, and nodding flower panicles from late spring to early summer. The flowers are greenish with purplish tinges, and the spikelets have long, twisted bristle-like structures (known as 'awns'), giving the plant a feathery, graceful appearance
