(12) Water plants

Greater Spearwort (Ranunculus lingua) is one of the stateliest of the ranunculus family. Growing on the shore, in reed beds, or in the water, it blooms in July and August and can be seen beside the Korentosilta bridge. Its flowers are bright yellow, 2.5–4.5 cm in diameter. The spearwort is very sensitive to the clarity of water. The rise in the turbidity of the Tainionvirta river may be the explanation for the decreasing numbers of greater spearwort in past few years.



The greater spearwort requires very clear water in order to flourish.

The white water lily (Nymphaea alba), the biggest natural flower in Finland, and its relative the cow lily (Nuphar lutea) have strong root stock, and they thrive in the small bays of the Tainionvirta.
