Sweet Flag Grass
Sweet flag, Acorus calamus, is a grass-like perennial that can grow up to 2 meters or 6.6 feet high. Sweet flag, along with the common cattail, thrives in wet areas like the edges of streams, ponds, and lakes. The thick, erect leaves resemble an iris. The flowers are greenish brown cylinders covered in little rounded spikes, but they rarely flower.
