Common on bare ground, walls, gardens, grassland, roadsides.  Plants from habitats where you might expect the rarer Mouse-ears usually turn out to be this one!

Flower diameter c 7-11 mm

ID: Flowers not clustered together in a tight head (except at early bud stage), and very lax by fruiting time.  10 stamens (occasionally 5 but if so check carefully to see that you don't have C diffusum or C semidecandrum).  Sepal tip hairless, hairs from lower down not normally projecting beyond sepal tip.  Petals about equal to sepals in length.  Bracts at base of flowering stalks wholly green or the upper ones with narrow pale margins.

Other features: Characteristic curved fruit capsules a common sight throughout summer and autumn.
