In the garden
Cortaderia selloana, known as pampas grass, is a large grass species reaching around 3.0 m and originating from temperate South America. Its size and upright habit are defining features, so allow adequate space when planting. Flowering occurs from August to October. Plant where it receives full sun and in soil that can be sandy, loamy or clay; the key is good drainage, although it will tolerate moist but well-drained conditions. In UK hardiness terms it is rated H5 (hardy) and it corresponds to USDA zones 7–11, so it will withstand typical winter conditions in many parts of the country. Positioning should account for its eventual height and the space it requires. Use the species where a tall grass is required and where a sunny, open location is available; give plants room from boundaries and structures to avoid overcrowding as they mature. Expect the stand to reach roughly 3.0 m and to produce its flowering display between August and October.
