Frogbit is a perennial, floating, dioecious plant. The stems are shortened with side shoots (stolons), on the tops of which the wintering buds were formed. The leaves are floating, arranged in a rosette, on long petioles, round-heart-shaped, 5-7 cm in diameter, with two large leaflets.

The leaves contain flavonoids, anthocyanins (cyanidin, pelargonidin), leucoanthocyanins (leucocyanidin).
