Pampas grass suffered bad press for a few years, following the trend of having them as lone plants in the middle of the lawn. They are now back in fashion, although this time they are firmly back in the border, planted alongside the swaying flower-heads of other ornamental grasses. ‘Pumila’ is a charming dwarf form that only reaches 1.5m (5ft) high. This may not sound very dwarf but, compared to the towering heights that other pampas grasses reach, it certainly qualifies for this description. Grow in any well-drained soil in a sunny position.
