Autumnal Water Starwort
Callitriche hermaphroditica
The Autumnal Water Starwort (Callitriche hermaphroditica) is an emergent perennial aquatic plant, growing in still and slow-moving water. With bright green leaves, it produces yellow or white blooms from July to October. In the winter, the foliage dies back and re-emerges in the following year. A hardy species, it adapts to a variety of aquatic habitats, making it desirable of aquaculture systems. It is widely distributed throughout Europe, but can be found in North America as well. Not only a beautiful addition to a water garden, the Autumnal Water Starwort provides shoreline protection, and an excellent food source for fish and waterfowl.
