The genus Crocosmia belongs to the Iris family (Iridaceae) and contains eleven or so species of cormous perennials, most of them native to southern and tropical Africa. A corm is a swollen stem base that is modified into a mass of storage tissue. A corm is technically different from a true bulb because it does not have visible storage rings when cut in half. Gladioli, crocus and autumn crocus are other examples of plants that grow from corms.
