Swamp sawgrass is a tall, robust native grass that forms large clumps in wetland areas. This evergreen perennial can reach up to 10 feet tall and produces brownish flower clusters during summer and fall. It requires consistently moist to wet soil conditions and thrives in full sun locations.
In an HOA neighborhood
