Weed profile: Mexican feather grass

Mexican feather grass
Nassella tenuissima, family Poaceae
Mexican feather grass is closely related to serrated tussock (Nassella trichotoma), a major pasture and environmental weed in temperate Australia. The two species can only be distinguished from each other when flowering.
Mexican feather grass is a highly adaptable, invasive grass species. It is capable of surviving in extremely variable climates and soil types, and is able to tolerate prolonged periods of drought, suggesting it could be more invasive than serrated tussock.
