Sisyrinchium Angustifolium Album
This is the rarer pure white-flowered form of this dwarf iris relative that could easily be mistaken for a clump of grass. It bears masses of yellow-centred, pure white, star-like flowers that appear in succession from May until August. In the wild it grows in mid western & eastern North America, from Newfoundland & Quebec to Florida & Texas. Over time it can spread slowly by seed, but it never seems to become an unwelcome intruder in any sunny location. Alternatively, clumps can be divided in early spring.
Seeds should be sown in spring and grown on in small pots before being planted in final positions in early summer. Alternatively just sow where needed in the garden.
Common name:White Blue-eyed Grass
