About Frogbit

Hydrocharis morsus-ranae, commonly known as common frogbit, is a perennial floating aquatic plant native to Europe and parts of Asia. Its small, glossy, rounded leaves form rosettes that float on the water's surface, resembling tiny water lilies. It is ideal for ponds, aquariums, or any still body of water, adding a natural touch and covering the surface.

Native range

Europe and temperate Asia

Care tips

It requires direct sunlight or partial shade to thrive and prefers still, nutrient-rich waters. It does not require substrate as it floats freely but benefits from a stable aquatic environment. Ensure it doesn't spread too rapidly, as it can become invasive and completely cover the water surface, blocking light from other species.
