Sometimes known as the Algerian or winter-flowering iris, this is the perfect plant for hot dry impoverished soil . The long, tapering, blue flower buds appear throughout winter and early spring on short stalks from the base of the plants although the plants are hardy, the flowers are very much at the mercy of the weather, so if it is bad, pick the buds and bring them indoors to open in a vase. In all but the mildest regions, the protection of a south-facing wall is vital for flowers to be produced, and this also protects them from much weather damage.
