heartsease

A species of violet (Viola tricolor), also called wild pansy, native to Europe. The flowers are blue, yellow, white, or a combination of these colours. (Family: Violaceae.)

The Heartsease (Viola tricolor) is a common European wild flower, growing as an annual or short-lived perennial.

Long before cultivated pansies were developed, the heartsease was associated with thought in the "language of flowers", often by its alternative name of pansy (from the French "pensée" - thought): hence Ophelia's often quoted line in Shakespeare's Hamlet, "There's pansies, that's for thoughts".
