Pampas Grass is a tall grass native to southern America forming large clumps growing up to 4m. Leaves are dark green with leaf base hairy for purple pampas and sparsely hairy for C. selloana.
Leaves snap readily when tugged.
Dead leaf bases spiral like wood shavings.
Flower-head erect, dense and fluffy. C.jubata bright purple fading to dirty brown, C.selloana white-pinkish fading to dirty white.
Pampas grass is a problem because is tolerant of a wide range of growing conditions. It seeds prolifically and is widely dispersed by wind, water, contaminated soil etc. It displaces groundcovers, shrubs, and ferns, creates fire hazards and provides habitats for rodents and possums.
