Swamp Rose Mallow (Hibiscus)

Woolgrass is a native perennial sedge that forms dense clumps in wetlands, ditches, and along shorelines. Its ability to thrive in saturated soils and shallow water, combined with its spreading growth habit, makes it especially valuable for waterside & riparian plantings, erosion control, ecological restoration, and naturalization projects.

The distinctive spikelets are covered in brown woolly bristles, which is where it gets the name Woolgrass. It produces seeds that are eaten by waterfowl and small mammals, while its dense stems offer cover and nesting habitat. It grows most actively in spring and fall, slowing or going dormant in the summer heat.

Swamp Rose Mallow (Hibiscus) has large white-pink showy flowers which attract hummingbirds and pollinators to your yard. It is a tall, fast growing perennial shrub. The flowers typically only last 1-2 days, but the plant will continue to rebloom throughout the season.

This hibiscus tolerates heat and humidity but does not do well when exposed to wind. Make sure the plant has access to lots of moisture for better flowering.

The Swamp Rose Mallow (Hibiscus) is also known as the dinner plate hibiscus because it can grow incredibly large flowers, as big as dinner plates.
