• Hibiscus moscheutos - Swamp Rose Mallow


    "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." (North Carolina Extension)

    Hibiscus Moscheutos Botany By Dr. John Hilty

    Mallow family (Malvaceae)


    "The preference is full to partial sun, wet to consistently moist conditions, and soil containing loam, silt, or some sand with organic material." (Hilty)

    Faunal Associations: 

    "The flowers are cross-pollinated by bumblebees and other long-tongued bees, including Melitoma taurea and Ptilothrix bombiformis (Rose Mallow bee). The Rose Mallow bee is a specialist pollinator (oligolege) of native Hibiscus spp. (Rose Mallows); it sucks nectar and collects pollen from the flowers, while other long-tongued bees suck nectar primarily. The Ruby-Throated Hummingbird is another nectar-seeking visitor of the flowers. Some insects feed on various parts of Rose Mallows. The introduced pest, Popillia japonica (Japanese Beetle), gnaws on the flowers and young leaves, while the aphids Aphis gossypii and Macchiatiella rhamni suck plant juices. The caterpillars of Pyrgus communis (Common Checkered Skipper) and the butterfly Vanessa cardui (Painted Lady) sometimes feed on the leaves, while the caterpillars of the butterfly Strymon melinus (Gray Hairstreak) feed on the developing seeds. The caterpillars of several moths also feed on Rose Mallows, including Acontia delecta (Delightful Bird-Dropping Moth), Anomis erosa (Yellow Scallop Moth), Automeris io (Io Moth), and Eudryas unio (Pearly Wood Nymph)."
