I came across a very neat plant while fishing, found out it is Potamogeton crispus.  Love the look of it. Has anyone experience with it in the aquarium?

I have not kept this plant.

Identification: Potamogeton crispus grows entirely as a submersed aquatic plant with no floating leaves.  Leaves are alternate, 4-10 cm in length and 5-10 mm wide.  Leaves are conspicuously toothed along leaf margins, sessile (attached directly to the stem), narrowly oblong, undulate (wavy like lasagna noodles) with a conspicuous mid-vein.  Leaf tips are obtuse (rounded or blunt), olive-green to reddish-brown, and somewhat translucent. Stems are flattened, channeled, with few branches.  Rhizomes are pale yellow or reddish, rooting at the nodes.  Small flowers (3 mm wide), with greenish-brown or greenish-red sepals form on a terminal spike above the waterline producing 3-4 achenes (fruits) per flower.

The unique seasonal phenology of P. crispus differentiates the species from other submersed aquatic plants found in North American waters.  In the colder regions of its range, turions (the primary reproductive propagule) break dormancy in the fall when water temperatures drop (Nichols and Shaw 1986). P. crispus survives the winter as whole, intact leafy plants (even under thick ice and snow cover) (Stuckey et al. 1978), then grow rapidly in early spring when water temperatures are still quite cool (10-15°C).  In early June plants flower, fruit, and form turions, and then plants senesce by mid-July (Tobiessen and Snow 1983) in most areas of its range.  The winter growth form of P. crispus is morphologically different from its spring or summer growth form, with leaves that are flattened, narrow, and blue-green in color with few stems and thin rhizomes (Tobiessen and Snow 1983).

Size: up to 5 meters in length (Holm et al. 1997)

Native Range: Eurasia, Africa, and Australia (Catling and Dobson 1985)

From what I can tell this is not something one would have in a typical tank? I also could not find much about it being used in aquariums.

Thank you!  I found the same information plus some on line. One man tried but did not get the rhizome, I think it may work if I do get that. Quite different in habits of growth.
