Bulrush
There are many varieties of bulrush found in Maryland and most are difficult to identify. The one bulrush that is most common and can cause the most problems is the great or soft-stem bulrush (S. validus). As a group, bulrushes are annual or perennial wetland or aquatic plants that can be found growing in clumps or over a large area of shallow water. The plants can vary in height from a few inches to over 6 feel.
