The genus name is derived from the Greek words krokos, meaning "saffron", and osme, meaning "odor" – from the dried leaves emitting a strong smell like that of saffron (a spice derived from Crocus – another genus belonging to the Iridaceae) – when immersed in hot water.[6]
The alternative name montbretia is still widely used, especially for the garden hybrid

Garden hybrids
Cultivation
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,[10] Ireland,[11] Australia,[12] New Zealand,[13] [14][15] North Carolina,[16] and the West Coast of the United States.[17][18]
Crocosmia are winter-hardy in temperate regions. They can be propagated through division, removing offsets from the corm in spring.
The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:
