Noteworthy Characteristics

Malva sylvestris, commonly known as common mallow but also known as wood mallow, tree mallow and high mallow, is native to Europe, western Asia and northern Africa. It is similar in appearance to the genera Hibiscus and Alcea. Over time, this species has escaped gardens and naturalized in many parts of the world. In North America, it has naturalized throughout southern Canada and the U.S. except for several States in the Deep South (Louisiana to Florida). Stems typically rise to 2-4’ tall clad with rounded to kidney-shaped, rough-hairy, basal leaves (2-4” long) each having 3-7 shallow lobes. Upper leaf lobes have a more triangular shape. Long-stalked, 5-petaled, bright rose-purple flowers with darker stripes along the petals bloom singly or in 3-5 flowered axillary clusters throughout summer (June to August/September). As the flower petals drop, a small, rounded, disc-shaped fruit (10-20 sections) begins to develop, purportedly resembling the shape of a miniature cheese wheel. This has led to a whole series of additional common names for plants in the genus Malva including cheese, cheeses, cheeseplant and cheeseweed.

Genus name is an ancient Latin name.

Specific epithet from Latin means growing in the woods.

MARINA is an erect, compact plant typically growing only to 18" tall. Features rich, 5-petaled, violet-blue flowers (to 1.25" diameter) with dark purple veins which appear over a long bloom period of early summer into fall. Flowers appear singly or in clusters in upper leaf axils. Leaves are coarse and hairy with 5-7 shallow lobes. A sport of M. sylvestris 'Primely Blue.'


No serious insect or disease problems. Rust typically develops as the summer progresses.
