Cortaderia selloana, commonly known as pampas-grass,^[1] is a flowering plant native to southern South America, including the pampas after which it is named.

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 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.

The specific epithet was given by Josef August Schultes and Julius Hermann Schultes in 1827, after the German botanist and naturalist Friedrich Sellow, who studied the flora of South America, especially that of Brazil.

Cultivation and uses[edit]

Cortaderia selloana in cultivation

The plant was introduced to Europe, North America and Australia as an ornamental grass, and, to a lesser extent, to provide food for grazing animals. The feathery flower head plumes, when dried, are widely used in flower arrangements and other ornamental displays.

There are several cultivars available, including:

• 'Albolineata' — a small cultivar which grows to only 2 m (6.6 ft) in height. The leaves are variegated, with yellow edges.
• 'Aureolineata'agm^[2]
• 'Pumila'agm^[3]
• 'Sunningdale Silver'agm^[4] — grows to a height of 4 m (13.1 ft) and has particularly dense flowering plumes.

Those marked agm have gained the Royal Horticultural Society's Award of Garden Merit.

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. As such, in some areas (for example California, Hawaii or Green Spain) it is regarded as an invasive weed, whilst in New Zealand and South Africa the plant is banned from sale and propagation for the same reasons.^{[citation needed]} Burning pampas grass does not always kill it at the roots, but chemical weedkiller does.

Swinging[edit]

A widespread urban myth is that pampas grass is used by swingers to advertise their presence to other swingers in the area. The most commonly repeated version states that in the UK and Ireland a patch of pampas grass is planted somewhere in the front garden to act as a signal to passersby that swingers live in the home. ^{[5][6][7][8][9][10]}
