Mouseear Chickweed

Cerastium glomeratum

Summary ⁶

Cerastium glomeratum is a species of flowering plant in the pink family known by the common names sticky mouse-ear chickweed and clammy chickweed. It is probably native to Eurasia but it is known on most continents as an introduced species. It grows in many types of habitat.

Comments ⁷

The distinctive characteristic of this chickweed is its dense cluster(s) of flowers. In particular, the pedicels of the flowers are the same length or shorter than the sepals (5 mm. or less). Several other species of chickweeds are similar in appearance, but at least some of their pedicels exceed 5 mm. in length (particularly when their flowers have transformed into seed capsules). The sepals of Glomerate Mouse-Eared Chickweed are somewhat unusual because they are covered with long forward-pointing hairs that may extend beyond their margins; other species of chickweed have sepals with shorter hairs. In general, the various species in the Cerastium genus are called "Mouse-Eared Chickweeds" because of the shape and hairiness of their leaves; these species usually have 10 stamens and 5 styles per flower. A scientific synonym of Glomerate Mouse-Eared Chickweed is Cerastium viscosum. Because of this defunct scientific name, this species is sometimes called "Clammy Mouse-Eared Chickweed."
