Callitriche palustris

This is a small plant that makes somewhat of a tangle of tiny leaves that make a dense carpet that sits on the surface of the water. The leaves are linear and shiny green. It produces many small white flowers that you may not even notice, but they should be present from spring through summer. The popular name ' starwort' comes from the star like effect of the leaf rosettes. This enjoys cool water and provides food for fish and a good place for aquatic insects to live in. It can be grown in a basket if it is necessary to constrict its growth. This stands around 3 cm in height with a 50 cm spread.
