is a very common immersed plant. It is
a prolific grower and can cover large areas.
Pickerelweed typically grows
to about two to three feet tall. Its leaves
are large, up to five inches wide, and are usually twice as long. Leaf
shapes are variable, but are usually lance-shaped. The easiest way to
recognize pickerelweed is by its spike of violet-blue flowers.
