]. It has a wide climatic tolerance, being present from the cold temperate climate of Alaska to the tropics of Puerto Rico, though it may be less common as the extremes of its range. It is predominant in temperate areas of North America and Europe. Pip and Simmons (1986) in Canada, and Sheldon and Boylen (1977) in the USA, studied the maximum depths at which a number of submerged aquatic plants were found, and the maximum recorded for any species was 12 - 14 metres for Elodea. In North America it has been recorded in neutral to slightly alkaline inland waters and in fresh to slightly brackish coastal waters

Propagation

Seed - seldom produced in Britain, if it is obtained it should not be allowed to dry out and is best sown immediately in water.
Division can be carried out at almost any time in the growing season. Simply break off a bit of plant and place in water - it will soon produce roots. The stem can be weighted with something like a stone and then thrown into a pond to allow the stems to root into the mud.
