When to see

January to December


False oat-grass is a tall, fluffy-looking perennial of grasslands, roadside verges and disturbed ground. Perhaps one of the most common grasses of these often overlooked places, it may well be familiar as the grass that so many of us catch in our hands and absent-mindedly strip of its seeds as we walk along. But, in fact, it plays an important role in stabilising dunes and cliffs.
False oat-grass mainly flowers from May to September, but can continue until the first frosts.

What to look for

The loose flower heads of False oat-grass have groups of brownish, oval spikelets (containing the flowers) with bristles at their tips. The long stem often turns brown after flowering.

Where to find


Did you know?

False oat-grass is one of a number of native grasses that are found on unimproved grasslands and make excellent shelter and nesting material for Field Voles. In turn, these grasslands become hunting grounds for Barn owls, which can be seen quartering the fields at dusk.
