About

Nymphoides aquatica is an aquatic plant in the Menyanthaceae, native to the southeastern United States from Texas to Maryland. It is known variously as the banana plant, banana lily, banana floatingheart, and the big floatingheart. It is most commonly called the banana plant because of its banana-shaped roots. These unusual roots store nutrients.

How to grow it

It is unusual in that it can be grown rooted or as a floating plant. It prefers a bright light and a tropical temperature range.

It can be propagated from the runners that arise naturally or by dividing the rootstock. Although a perennial it is best replaced by new stock every 4 or 5 years. The rootstock should not be entirely buried in the substrate when planting. In the winter and in more shaded conditions, it forms submersed rather than floating leaves.
