About this plant
This water plant has long, slender, somewhat arrow-shaped leaves. They stand well clear of the water, pointing upwards and held on robust stems. In late summer the leaves are joined by columnar blue flowers which are cool in effect. The whole plant has a streamlined and elegant appearance.

Water frequently to keep the soil moist
The plant thrives in moist or boggy soil, doesn't tolerate dryness and should be watered frequently, not only after a period of drought, but if the soil begins to dry out spring to autumn. Check plants in pots more frequently, especially in hot weather.
