Deservedly popular, this has delicate flax-blue, slightly fragrant flowers with spectacular, ruffled petals in May and June and fans of sword-shaped, grey-green leaves. This tall bearded iris is gorgeous planted en masse in a sunny, well-drained border or as part of a cottage-garden scheme.
Garden care: Plant shallowly with the upper part of the rhizome sitting on the surface of the soil, incorporating a low nitrogen fertiliser in the planting hole. After planting remove the upper-most third of the leaves to protect against wind-rock. In exposed areas stake with bamboo canes in early spring. Remove the stems after flowering from the base as this will concentrate the plant's energy into producing new rhizomes. Divide and replant about every three years.
