This plant is often called Neptunia Aquatica, but its proper name is Neptunia Oleracea. It belongs to the same family as legumes. The plant is beneficial to other pond plants by adding nitrogen back to the pond.

Fascinating Fact! The leaves of this plant are 'sensitive' and curl inward when touched. The plant returns to normal in a few minutes.

Planting Instructions

No planting is necessary; simply place on the surface of the water in full sun to part shade. However, one end of the plant may be planted in soil to anchor it in one place. We sell this item potted and floating. Again, it need not be potted but will grow more rapidly if planted in heavy loam soil in shallow water.
