Common Name: Montbretia, Crocosmia
Regarded as one of the hardiest cultivars, C. 'Lucifer' adds a tropical flair to northern gardens. Beginning in midsummer and continuing into early fall in some climates, brilliant flame-red flowers stand in rows on wiry, gracefully arched stems that are perfect for cutting.
Crocosmia's broad, sword-like leaves are attractive even when the plants are not in bloom and, from a design standpoint, are effective for adding a spiky textured element to the landscape.
Plant Crocosmia in full sun and well-drained soil that does not become waterlogged. Its fleshy roots (corms) should be planted 2-4" deep and 6-8" apart.
Crocosmia will quickly grow and overcrowd itself, and therefore should be divided every 2-3 years. Alternatively, offsets of the original plant may be lifted and moved. In zones 1-4, corms should be lifted and stored indoors over the winter, much like cannas or dahlias. In zones 5-7, a deep winter mulch will help to protect the roots and increase the plant's chances of survival.
