Vallisneria australis 'Curly'

Vallisneria australis 'Curly' is a cultivar of the giant vallisneria; the designation Vallisneria gigantea 'Curly' is regarded as an erroneous name for the same plant.¹ The origin of the cultivar is unknown.

The species V. australis is native to Australia and has also been introduced to several European countries.² It was only described as a separate species in 2008, after molecular studies had separated the Australian plants from V. americana; according to these studies, the giant vallisnerias traded as V. gigantea or under cultivar names also belong to it.³ One specialist author, however, considers it very unlikely that only plants of Australian origin are kept in aquaria.³ The cultivar propagates by runners, is considered easy to keep and is also suitable for garden ponds, but does not grow emersed.
