Salvinia cucullata

Salvinia cucullata is immediately distinguishable from other salvinia species by its unique leaf shape: each floating frond is rolled into a funnel or cup form, giving dense mats a bubbly, three-dimensional texture quite unlike the flat rafts of other floating plants. This distinctive morphology makes it particularly eye-catching in paludariums as a surface accent or partial surface cover. Native to Southeast Asia, it is well adapted to warm, humid tropical conditions.

In terms of growth rate and care it is similar to other salvinia species — tolerant, easy, and fast-growing under good light. The cupped leaves are somewhat more robust than those of S. natans and are less likely to be damaged by surface agitation. Like all salvinia species it requires no fertilisation and performs best in nutrient-rich paludarium water.

Light: Medium to high; 2,000–5,500 lux; the cupped leaves are most tightly formed under medium-bright conditions. CO2/Humidity: No CO2; tolerates gentle water movement better than flat-leaved salvinia species. Fertilisation: No direct fertilisation; relies entirely on water-column nutrients. Placement: Float freely on the water surface; maintain partial coverage by removing excess mats regularly. Propagation: Naturally self-propagates by fragmentation; no special effort required.
