Comfortroot (Hibiscus aculeatus), also known as Pineland hibiscus, is a large perennial wildflower that occurs naturally in wet to mesic pinelands, and along the edges of savannas, bogs and roadside ditches. It typically blooms late spring through fall and attracts many pollinators, especially bees.
Comfortroot’s showy blooms are 3–4 inches wide, with five cream-colored petals that have scalloped edges and appear pleated. The bloom’s center is a deep purplish-red. The plant has a semi-woody base from which multiple stems emerge. Leaves are palmate and scabrous with toothed margins. They are alternately arranged. Seeds are borne in large scabrous capsules. Stems are also scabrous.
The common name Comfortroot may allude to the belief that the plant’s mucilaginous roots has soothing properties.

Garden tips: Comfortroot is an attractive addition to a moist landscape. It appears shrubby but will die back in the winter and all but disappear. Annual pruning to the ground may be necessary. It can tolerate seasonal flooding and is also drought tolerant; however, it will not survive if soils are not moist or wet for part of the year. It will self-seed, but not prolifically.
