    The sumptuous petals of this bearded iris are deep purple, which look almost black in certain lights. They have a brown beard and appear in early summer on upright stems above the sword-shaped, grey-green leaves. Plant in big swathes for maximum impact, or mix it in smaller clumps in a sunny, well-drained border among other perennials. A tall variety that will need staking if planted in exposed positions.

  • 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.
