Giant rat's tail trass

Family: Poaceae
Scientific name: Sporobolus natalensis
Description: Plant Form Upright tussock forming perennial grass. Size Up to 1.5 m tall. Stem Long, upright, clump together to form tussock. Leaves Very long, narrow blades, 20-70 cm long. Flat or somewhat rolled. Flowers Elongated rats tail-like heads 20-30 cm long. Fruit and Seeds Dark green or greyish-green spikelets containing 2 bracts with numerous yellowish-brown seeds. Habitat Disturbed areas, roadsides, woodlands, urban bushland, parks. Distinguishing Features Very similar to other introduced Rats-tail grasses (Sporobolus species) so expert advice is recommended, however spike-shaped rather than pyramid-shaped head may help distinguish it from Sporobolus pyramidalis (also known as Giant rats-tail grass).
