A really arresting sight in May and June when the violet flowers and cornflower-blue beards appear among sword-shaped grey-green leaves. This may not be one of the fanciest irises around but what it lacks in originality it makes up in quantity, flowering prolifically throughout early summer.

  • Garden care: Bearded irises prefer full sun and neutral-alkaline soil but if you have acidic or peaty soils you can top dress with lime before planting for good results. 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. Divide and replant about every three years.
