Enneapogon nigricans, known by the common names blackheads,[1] bottle washers, pappus grass,[1] purpletop grass,[1] and niggerheads,[3] is a perennial Australian grass.

Distinctive lance-shaped seedheads appear in late spring and summer. They form at the top of wiry stalks over 30 cm long. They start as an olive green colour, but dry to a light brown. The seed itself is much like a parasol in appearance, and is around 5mm across. Germination is slow and unreliable and requires warm temperatures.[4]

Leaves are smooth and of a bright, light green. Plants like sunny positions and generally grow in sunny, open mallee forests. Plants form tall dense tussocks to a maximum of only 20 cm across.[5] They die down in late summer, before reshooting when the rains return.
