Pampas Grass is a super tough, long-lasting garden plant, which will almost look after itself. Cortaderia selloana 'Pumila' is a more compact variety, staying at just 1.2m (3.9'), and is much more manageable than its larger cousin!The tufted evergreen plants of Pampas Grass are perfect for filling a gap in a border, and 'Pumila' is good for small gardens too. Plants give all year interest for the garden, although are at their best in August when the silvery plumes appear from the very centre of the grassy plants. Height and Spread: 1.2m (3.9').
