Cortaderia selloana
Template:Short description {{#invoke:other uses|otheruses}} Template:Speciesbox
Cortaderia selloana is a species of flowering plant in the family Poaceae.<ref name=KewPOWO/> It is referred to by the common name pampas grass,<ref name=BSBI07>Template:BSBI 2007</ref> and is native to southern South America, including the Pampas region after which it is named. It is widely distributed throughout the world as a cultivated ornamental and invasive species.
EtymologyEdit
Cortaderia is derived from the Argentine Spanish name 'cortadera', meaning 'cutter', in reference to its razor sharp leaf margins.<ref name="gledhill">Gledhill, David (2008). "The Names of Plants". Cambridge University Press. Template:ISBN (hardback), Template:ISBN (paperback). pp 122, 348</ref>
Selloana is named for Friedrich Sellow (1789–1831), a German botanist<ref name="gledhill" /> and naturalistTemplate:Citation needed from Potsdam who worked as a plant collector in Brazil.<ref name="gledhill" /> He studied the flora of South America, especially that of Brazil. The specific epithet selloana was given by Josef August and Julius Hermann Schultes in 1827.Template:Citation needed
EcologyEdit
The native range of C. selloana includes Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay. This region is dominated by tropical forests and grasslands, but C. selloana is typically restricted to moist soil within riparian areas. It is found at lower elevations and at moister sites than the closely related C. jubata. It requires areas with plentiful light and soil moisture. It is a common invasive species in temperate regions around the world, where it can be found growing in moist, disturbed soil.<ref>Template:Cite journal</ref>
ControlEdit
Pampas grass can be controlled through herbicide treatment. To accomplish this, the grass is cut down near the base. Next, a 2% glyphosate chemical solution is combined with a silicone-based surfactant and applied to enhance the penetration potential. This method works best in the fall because there is overall better control compared to other seasons. Another control method is to cut and bag inflorescences to prevent seeds from spreading or pulling seedlings.<ref name="autogenerated1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Population biologyEdit
Okada et al., 2007 find C. selloana populations are best distinguished by a Bayesian analysis of genetic features such as microsatellites.<ref name="Sample weedy and invasive plant populations for genetic diversity analysis">Template:Cite journal</ref> Algorithms such as STRUCTURE are suitable for this.<ref name="Sample weedy and invasive plant populations for genetic diversity analysis"/>
In cultureEdit
Author Li Hengrui ({{#invoke:Lang|lang}}), whose work Kite Capriccio ({{#invoke:Lang|lang}}) describes life as a child in 1950s Fengtai County, Anhui mentions the use of the long stem of the Puwei (Template:Linktext, Chinese for Cortaderia selloana) in the construction of kites.<ref>Putonghua Shuiping Ceshi Gangyao. 2004.

Several media outlets reported in the 2010s that it was planted by some couples who practise swinging in the United Kingdom as a way to indicate to other swingers that they enjoy that lifestyle.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> The reports caused a plunge in already declining sales, but the odd association has been dismissed by enthusiasts of the plant and gardening experts as "silly".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref>
