  • Cortaderia selloana, commonly known as Pampas Grass or Uruguayan Pampas Grass, is a tall grass native to southern South America, including the pampas after which it is named, and Patagonia.

    Pampas grass is a tall grass, growing in dense tussocks that can reach a height of 3 m. The leaves are evergreen, long and slender, 1–2 m long and 1 cm broad, and have very sharp edges (so they should be handled with care). The leaves are usually bluish-green, but can be silvery grey. The flowers are produced in a dense white panicle 20–40 cm long on a 2–3 m tall stem.
