- Description
-
Rose Mallow is a herbaceous perennial that may grow 5 to 7 feet tall. The leaves are alternate with a toothed margin. Lower leaves may have three lobes. White flowers with a burgundy center first mature in summer and continue into early fall. Rose mallow is native to wetlands and creek edges in the southeastern USA and is found in all areas of NC. It prefers full to partial sun in wet to constantly moist soils containing loam, silt, or some sand with organic material. The flowers of cultivars vary in color and can be up to 12 in. across on compact plants. This plant is slightly salt tolerant.
Use Rose Mallow in low place of the garden, as a specimen, along streams or ponds or as a temporary summer screen or hedge. It can also be grown in large containers.

Insects, Diseases, and Other Plant Problems: Japanese beetles can severely damage foliage if left unchecked. Whiteflies, aphids and scale are occasional insect visitors. There is some susceptibility to leaf spots, blights, rusts, and canker. Leaf scorch can occur if soils dry out. Healthy plants grown in the proper environment usually do not have problems and do not need staking. This plant is occasionally damaged by deer.
