Cultivation details
An aquatic plant, floating by means of inflated petioles, it succeeds in still or slowly-flowing water requiring a position in full sun and a slightly acidic water with a rich planting medium[200]. Plants require a high summer temperature in order to perform well, they are not frost hardy[206]. Some botanists regard this species as no more than a part of the one highly polymorphic species T. natans[200]. This species was used for food in Neolithic Britain[200].
