|C. gigantea is more commonly known as C. luciliae, see C. luciliae for more information. Small, self-seeding bulb suitable for rock gardens. Leaves are basal and strap shaped, 3 inches to 8 inches long and medium green. Delightful, star-shaped, blue flowers with white centers grow in clusters in early spring. 'Alba' has white flowers and 'Gigantea' has large leaves and violet blue flowers with a white throat. Bulbs should be planted 3" deep in September or October in a slightly shady area. A wonderful bulb for naturalizing along woods' edge because they will self-sow over time.
