Threestamen waterwort, Elatine triandra, is a small creeping plant that is widely distributed from the temperate to the tropical climate zone: from Northern America over Europe, Asia and Australia to New Zealand. [1]. In nature, E. triandra is predominantly a pioneer plant growing on bare loam soils in ponds, rivulets and rice paddies that fall dry periodically and are often rather low in nutrients. [1],[2]. Elatine triandra is rare in Germany, and its populations are receding. It is threatened by intensified pond-farming and the eutrophication of waterbodies. [2].
Those plants of Elatine triandra sold in trade probably originate from Asia.

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.
