Sisyrinchium Angustifolium

Sisyrinchium angustifolium is a dwarf iris relative, that could easily be mistaken for a clump of grass were it not for the yellow-centred, bright blue star-like flowers that appear in succession from May until August. In the wild it grows in mid western & eastern North America, from New Foundland & 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.
