The Common Bulrush is a tall, slender plant with a straight, cylindrical stem that tapers to a point at the top. Its surface is smooth with a slight sheen, resembling wet reeds, and features a subtle vertical striation pattern along its length. The color ranges from a deep green at the base to a lighter, almost golden hue at the tip, with small, brown, cigar-shaped flower clusters near the top adding texture and contrast.
