This lovely, little grass is native to South America.
It forms a slow-growing, well-behaved clump of beautiful metallic-blue leaves, bearing taller stems of small blue flowers in early summer. The flowers turn a pale buff colour in autumn but the main clump retains much of its blue sheen over winter.
Makes a fine edging plant if the soil is well drained and in full sun.
Very low maintenance, non-invasive and tidy. De-thatch in spring to allow room for fresh growth.
