Hibiscus laevis (Halberd-Leaved Rose Mallow) is a herbaceous perennial with erect stout stems boasting large hollyhock-like flowers, up to 6 in. across (15 cm), with spreading petals in white or pink, and a sharply contrasting maroon or purple throat. Each 5 petaled flower has a conspicuous, protruding, creamy-white to pale yellow staminal column. Blooming from the axils of the leaves in late spring to fall (depending on geographic location), the cup-shaped blossoms open by day and close at night. The showy flowers attract butterflies, moths, and bumblebees. But even without these gorgeous blooms, this plant is worth growing for the handsome foliage of alternate, three-lobed leaves, 6 in. long (15 cm), which resemble the shape of the halberd used in the 15th and 16th centuries. Hibiscus laevis is a strikingly showy North American species that is excellent for wetland gardens, perennial gardens, bogs, or pond areas.

• Grows with an upright habit, up to 4-6 ft. tall (120-180 cm) and 2-3 ft. wide (60-90 cm). The plant has a deep taproot, but it spreads easily via seed.
• Thrives in full sun in organically rich, medium to wet soils. Tolerates some light shade, but best flower production and disease resistance occur in full sun. Tolerant of heat and humidity as long as the soil remains evenly moist.
• Plant in borders for dramatic summer blooms. Great flowering plant along streams or ponds or in native plant gardens.
• No serious pest or disease issues. Deer resistant.
• Propagate by seed or stem cuttings.
• Native to the eastern and central United States,  from New York to Florida, west to Texas, and north to Minnesota.
