Care

Nymphoides humboldtiana is a floating-heart from tropical America, with small, rounded floating leaves and fringed white flowers like the other water snowflakes. We could not reach a detailed source for it, so its size and aquarium behaviour are not documented here. Some botanists treat it as part of the widespread Nymphoides indica. Grow it like other Nymphoides: plant it in a nutrient-rich substrate in the midground, give it good light, and remove floating leaves if you want to keep submerged growth. It may flower at the surface in open tanks. Water figures are our estimate, not from the sources. Sources: Wikipedia, List of freshwater aquarium plant species. Checked October 2026.

Breeding

Like other Nymphoides it should form plantlets at the base of the leaf stalks, which can be detached once rooted.

Compatibility and tank mates

Snails and plant-eating fish may nibble the leaves. Floating leaves shade plants below. Suits tropical tanks and warm tubs.
