Pollination is achieved by bees, moths and beetles.   The relatively heavy pollen is not adapted for wind pollination although many species flower in windswept places.

Crocus etruscus pollinated by a bumble bee in early spring. (UK garden grown.)

Seed capsules emerge towards the end of the growing season as the leaves die away.

Seed capsules have three locules (compartments) and can contain many seeds. The seeds vary in size and in their surface features. (more details and images of these will follow in a future update.)
