Swamp Sawgrass

Cladium mariscus
native · Hill Country

Swamp Sawgrass is a grass native to the Texas Hill Country that grows 8–10 ft tall and 5 ft wide. It wants full sun or part shade and medium water. Blooms green in spring, summer and fall. Evergreen — it holds its leaves through winter. Good for aquatic wildlife, birds, moths and small mammals.

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.
