Myriophyllum pinnatum originates from the east of the USA, where it grows in shallow waters or the mud on the edges of lakes and ponds as well as in marsh woods. It has been in aquaristic cultivation and in trade for a long time, however, it is usually known under the name Myriophyllum hippuroides.
The stem of the submersed plant is green to red, whereas its finely pinnate leaves are green. Other than most milfoils like M. aquaticum or M. mattogrossense, its leaves do not only grow in whorls but also alternately. The distances between the nodes respectively the leaves are very short so the plant has a very dense foliage.

Wasserpflanzen sind ein fester Bestandteil der meisten Aquarien. Beim Aquascaping, dem Naturaquarium, Biotop-Aquarium oder dem Gesellschaftsaquarium sind Wasserpflanzen nicht nur für die Wasserqualität entscheidend, sondern sorgen auch stets für eine optische Aufwertung des Aquariums.
