In the garden
Cortaderia selloana 'Roi des Roses' is a large perennial grass from southern South America that forms a substantial upright clump and produces its flowering display from August to October. Expect a plant that will occupy vertical space up to around 3.0 m, so consider its mature height when choosing a spot. Place the grass in full sun; it tolerates a wide range of soils — sandy, loamy or clay — provided they drain reasonably well or remain moist but well-drained. The cultivar is rated H5 for UK hardiness, so it will survive typical winter conditions across most of Britain; gardeners in colder microclimates should site it out of cold pockets. Use 'Roi des Roses' where a tall, structural grass is wanted: as a single architectural specimen at the back of a border or where height provides separation between garden zones. Its size makes it less suitable for very small plots, but in larger beds it delivers a clear seasonal statement. Expect the plant's flowering period, August to October, to be the most prominent phase of its year.
