The largest Salvinia species is Salvinia oblongifolia, with up to 6 cm long and 2.5 cm wide leaves. It inhabits shallow stagnant waterbodies in Central and Eastern Brazil. This floating fern was already cultivated in Germany in 1910/11, but disappeared later on. In 1995 it was re-introduced by professor Elias R. de la Sota (Argentine) when he gave the plant as a gift to the Botanical Garden Berlin-Dahlem. S. oblongifolia has been available in trade infrequently since then.

Nutrient-rich water and high temperatures of 27 to 29 °C and intensive light provide for optimal growth for this large, attractive floating fern. Less favourable conditions cause it to develop a smaller, dwarfish habit, like other Salvinia species do, too.
