Rose Mallow, Halberdleaf

Hibiscus laevis (Halberdleaf Rosemallow)

Also known as halberd-leaved rosemallow, Hibiscus laevis is a showy, moisture-loving perennial native to central and eastern North America. Named for its distinctively shaped leaves that resemble a halberd (a medieval weapon), this hibiscus thrives in wetlands and along streambanks, where its large, pink, hibiscus-style blooms provide a bold splash of color from midsummer into fall. It’s a favorite among pollinators and can be an important structural and floral element in native gardens, rain gardens, and restoration projects.

Key Characteristics

• Nectar magnet for pollinators
  The bold, five-petaled pink flowers are rich in nectar and attract native bees, hummingbirds, and butterflies—especially species like the eastern tiger swallowtail and monarchs. Their large size and open structure make them ideal for many pollinators.
• Supports insect biodiversity and overwintering
  As a tall herbaceous perennial, Hibiscus laevis offers shelter and overwintering habitat for beneficial insects, particularly when stems are left standing through winter. Its sturdy form and late-season blooming extend food availability into the fall.
• Streambank stabilization and erosion control
  With a strong root system adapted to moist soils, this plant is ideal for streambank restoration, wetland buffers, and erosion-prone areas. It thrives in saturated soils and helps hold soil in place, making it a valuable regenerative landscaping tool.
• Striking addition to native and permaculture gardens
  Integrates beautifully into rain gardens, wet meadows, and food forests with wet areas. It’s a natural companion for other moisture-loving natives like Carex, Iris versicolor, and Joe-Pye weed, forming layered habitat for both wildlife and visual impact.
• Edible flowers with traditional uses
  While not widely used medicinally like some other hibiscus species, the flowers are technically edible and can be used sparingly as a decorative salad garnish. Historically, other hibiscus species were used in teas and poultices, though H. laevis is primarily ornamental and ecological.
