Heartsease (Viola tricolor) is a common European wild flower, growing as an annual or short-lived perennial. It has been introduced into North America, where it has spread widely, and is known as the Johnny Jump Up (though this name is also applied to similar species such as the Yellow Pansy). It is the progenitor of the cultivated Pansy, and is therefore sometimes called Wild Pansy; before the cultivated Pansies were developed, "Pansy" was an alternative name for the wild form.
