- Description

Seashore mallow is a native short lived subshrub or wildflower in the Malvaceae (mallow) family. Also known as sweat weed, Virginia saltmarsh mallow, and salt marsh mallow, this native plant is found in marshes and brackish water along the eastern seashore of the United States.
Seashore mallow is moderately salt tolerant growing in sunny wet to well-drained but moisture retentive sites. It grows 3 to 6 feet tall and 2 to 4 feet wide with soft gray green angular leaves.
The beautiful hibiscus-like pink flowers appear from July to October with their nectar attracting pollinators like hummingbirds and butterflies.
This plant was selected as the 1990 NC Wildflower of the Year, a program managed by the North Carolina Botanical Garden with some financial support from the Garden Club of North Carolina.
Insects, Diseases, and Other Plant Problems: No significant problems.
