Additional Info
Bell-shaped, pink-purple flowers occur in dense clusters. Plant may form sizable patches at the edges of lakes and sluggish streams or on floating bog mats. Wherever a stem touches the water, air-filled, spongy tissue may develop. This tissue buoys the stem so that it may root and form a new arching stem. The self-rooting tips of branches can be removed and transplanted. Despite one of its common names and its willow-like leaves, the plant is not related to the willows.
Good for large bog gardens and pond margins, often arching over the water. Var. verticillatus occurs mostly near the coast; var. laevigatus is mostly inland.
