Myriophyllum sibiricum is a species of water milfoil known by the common names shortspike watermilfoil,[4] northern watermilfoil, and Siberian water-milfoil.

It is native to Russia, China, and much of North America, where it grows in aquatic habitat such as ponds and streams.

It generally grows over a meter long, its green stem drying white.

It is lined with whorls of fanlike green leaves divided into many narrow, feathery lobes.

The erect inflorescence is a spike of small flowers up to 8 centimetres (3 inches) long which grows above the water's surface.
