Pampas Grass

Cortaderia selloana | Rating: 2 votes | Print / Pdf

A widespread urban myth is that pampas grass is used by swingers to advertise their presence to other swingers in the area. Try planting some in your garden and see who enquires about it…

Cortaderia selloana is also known as Pampass grass, named after an area of fertile lowlands in South America where it grows naturally. It's a tall grass that grows in clumps up to ten feet tall. It has long narrow leaves that are very sharp edged. These leaves are evergreen and blue/grey or silver colour. It grows tall stems, at the top of which bloom masses of feathery creamy white flowers, giving a feather duster effect. A stunning addition to the garden and an interesting cut flower too. It will like fertile well-drained soil and plenty of sun.
