Crocosmia paniculata (kroh-KOZ-mee-ah pan-ik-yah-LA-tah)

Family: Iridaceae Non-native Herbaceous (3-15 ft)

Zigzag crocosmia is a clump-forming, herbaceous perennial member of the iris family (Iridaceae). The species is native to South Africa, where it grows on moist, rocky and grassy slopes, and forest edges. The species epithet is Latin for “pannicle” and describes the branched inflorescence. The species grows in full sun or partial shade. It prefers continuously moist, humus-rich soil. Although cold-hardy, it is not likely to withstand freezing temperatures. If grown in cold climates, the corms can be lifted for the winter, or a layer of mulch can be applied to protect the corms from freezing. It arises from a corm that will feature crimped basal olive green leaves and showy zigzag red spikes of flowers. The flowers appear alternately along the stalks. Division can be accomplished after dieback occurs following its bloom period, or in the early spring before growth starts. Cut back the faded foliage in the fall or early spring. Use Zigzag crocosmia in herbaceous borders in children’s, butterfly, or cutting gardens. Insects, Diseases and Other Plant Problems: Regions with hot, dry summers will subject the plant to foliage damage from the glasshouse red spider mite. Somewhat slow to reach maturity, it can take up to three years. More information on Crocosmia .
