Collins, 150; Readers Digest, 96
This is a medium or tall perennial with kidney shaped leaves and deeply divided leaf stems. The flowers are solitary rose pink on stalks. It likes grassy places and scrubland.
See also Common mallow ((Malva sylvestris). This is a large sprawling tall perennial with pale and sometime dark pink or purple flowers, flowering from June to October. The plant is most abundant in waste areas and on dusty tracks and roadsides. It is a relative of the Hollyhock. By the 8th Century BC, young Mallow shoots were eaten as a vegetable and also in Roman times. In mediaeval times the plant had a reputation as an anti-aphrodisiac promoting sobriety.
