Nymphoides aquatica is a Southeast native floating-leaf plant with round, lily-pad-like foliage and small white flowers held above the water. It spreads by runners and can carpet quiet pond bays — excellent shade for fish, frog perches, and dragonfly drama. The "banana plant" nickname comes from chunky winter tubers the aquarium hobby loves; in nature those tubers help it survive dry-downs. In subtropical and tropical Americas it is right at home in sheltered, acidic to neutral ponds. In tiny water features, thin runners so it does not smother everything. Full sun to light shade; flowers best with sun. Still or slow water; rooted in bottom muck with floating leaves. Do not let the pond dry completely for long if you want to keep stands. Detach plantlets from runners. Tubers can be planted in submerged substrate in spring. Thin floating mats when coverage blocks light for submersed plants you value. Work in cool morning air so broken fragments drift less. Compost removed biomass in active piles; do not toss live pieces into new water bodies.
