When to see

January to December


Common cotton-grass is familiar as the fluffy, white seed heads that dot our brown, boggy moorlands and heaths as if someone has thrown a giant bag of cotton wool balls across the landscape. Blowing in the breeze, they bring these isolated places to life in summer. Despite its name, common cotton-grass is a member of the sedge family, rather than being a grass.

What to look for

The white, cottony seed heads of common cotton-grass are extremely distinctive. It has dark green, narrow leaves and drooping flower heads.
