Description
The Cutleaf Watermilfoil is native to lakes and swamps in the eastern part of North America. Labeled "Myriophyllum scabratum" and "M. hippuroides", it is a standard aquarium plant for many years. Its long, moderately branched stems are reddish and very densely set with finely pinnate, medium green leaves.
Myriophyllum pinnatum is not very demanding, however at least medium lighting and lower temperatures up to 25 °C are recommended. According to its temperate to subtropic origin, it is also well suited for cold water tanks.
This densely and finely leaved stem plant looks well as a group in the midground to background of taller aquariums. It is also recommendable for North America-themed biotope tanks.
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.
