How does crocosmia propagate?

Crocosmia grows from a corm which is a root structure similar to a flower bulb. Over time, the corms produces small cormels, or offshoots, that can be planted to grow new crocosmia. Propagating the plant is often done by seed in late winter or by dividing the corms and cormels before new growth begins in early spring.
