About
Crocosmia (), also known as montbretia (), is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa, ranging from South Africa to Sudan. One species is endemic to Madagascar.
How to grow it
Crocosmias are grown worldwide, and more than 400 cultivars have been produced. Some hybrids have become invasive, especially C. × crocosmiiflora hybrids, which are invasive in the UK, Ireland, Australia, New Zealand, North Carolina, and the West Coast of the United States.
Crocosmia are winter-hardy in temperate regions. They can be propagated through division, removing offsets from the corm in spring.
