Crocosmia x crocosmiiflora is a beautiful perennial summer flowering bulb. During July and August, thin sprays of deep red flowers develop, contrasting beautifully with the plant's thin, sword-like green leaves. C. x crocosmiiflora is best suited to a sunny or partially shaded location that has moist yet well-drained soil. It is a late flowering plant, making it ideal for summer borders as C. x crocosmiiflora blooms when many other plants have finished flowering. During March or April, C. x crocosmiiflora should be dug up and divided to improve overall health and vigour.
