With its delicate appearance resembling moss, Salvinia natans emerges as a stunning annual floating aquatic fern, a delightful addition to any pond in the UK. Sporting two floating leaves and one submerged leaf, each plant showcases elliptical to ovate floating leaves adorned with dense stiff hairs on the upper surface, while the submerged leaves boast finely dissected structures ideal for nutrient absorption and oxygenation. Thriving under optimal conditions of full sun and still to slow-moving water, it exhibits rapid growth, often necessitating frequent harvesting to prevent overshadowing of other aquatic flora. A vital contributor to pond health, this low-maintenance plant aids in oxygenation and water clarification, effectively mitigating algae growth by efficiently utilising excess nutrients in the water column.
