Halberdleaf Rosemallow

Hibiscus laevis

native · Hill Country

Halberdleaf Rosemallow is a wildflower native to the Texas Hill Country that grows 5–6 ft tall and 8 ft wide. It wants full sun or part shade and high water, and handles clay soil. Blooms purple in mid summer. Good for butterflies.

Wet ground only. A wetland plant: it needs standing water or saturated soil — a pond edge, creek bank or rain garden, not a dry upland bed.
