Cortaderia selloana, commonly known as pampas grass, is a flowering plant native to southern South America, including the Pampas region after which it is named. There are around 25 species in the genus Cortaderia.
It is a tall grass, growing in dense tussocks that can reach a height of 3 m (10 ft). The leaves are long and slender, 1–2 m (3 ft 3 in–6 ft 7 in) long, and 1 cm (3⁄8 in) broad, with very sharp edges. The leaves are usually bluish-green, but can be silvery grey. The flowers are produced in a dense white panicle 20–40 cm (8–16 in) long on a 2–3 m (6 ft 7 in–9 ft 10 in) tall stem.
Pampas grass is highly adaptable and can grow in a wide range of environments and climates. It also seeds prolifically, with each plant able to produce over one million seeds during its lifetime. Its seeds can be wind-dispersed.
During summer, Pampa grass produces its seeds and it is at that time when it is easier to recognize, but it is during autumn when seed dispersal makes the species potentially more dangerous for the environment.
