Bulrush (Shoenoplectus lacustris)
The Bulrush is the classic reed, a smooth, green, round stemmed plant with a grass-like flower. (Rushes are round, sedges have edges!)
The Bulrush is very common and probably the sort of plant you pass by with a second glance because it is so mundane and has little to attract your attention, although a close look at its little flower that appears in July and August is worth stooping down for..
It grows by rivers, lakes and ponds, especially in silty places, and can be abundant where it occurs.
