Hi, Following up on Aaron's suggestion I looked at my Transvaal field guide and found this: Aristea woodii "An attractive perennial , 400-600 mm high when in flower, with tapering leaves and an erect inflorescence of shimmering pale blue, mauve or white flowers which are 15-20 mm wide. Each bloom opens in the early morning and by noon it has twisted into a tight spiral, becoming inky-blue in colour. Flowering time is from December to February. Widely recorded along the entire escarpment and foothills, in open grassland or swampy areas." Field guides never include all possibilities, but the only other irids listed are Hesperantha coccinea, a couple of Crocosmias, a number of Gladiolus and a couple of Watsonias. None of them are violet blue. Mary Sue
