Water buttercup - Ranunculus lingua


The Water Buttercup, also known as Ranunculus lingua) is a stoloniferous aquatic plant native to central Europe and Asia. It looks like a small head of oval leaves that grow on stolons deeply anchored to the ground; from the center of the leaves rise some long, fleshy, poorly branched stems, which bear long oval leaves, of a bright green color; in spring and summer it produces golden yellow flowers, which bloom solitary at the end of long stems. Besides being a plant of great aesthetic impact, the buttercup is a really important species for ponds and ponds in which it develops. In fact, it belongs to the group of oxygenating plants as it is able to maintain the water of the place where it grows clean and oxygenates. Thanks to this capacity, it allows the survival of small aquatic animals, fish and turtles.


The water buttercup prefers sunny positions, but develops without problems even in the partial shade. It does not fear the cold and in most of Europe it can also be found in the wild. However, pay attention to the different cultivation methods. If cultivated in the open ground, the ranunculus lingua may be exposed to direct sunlight; if, on the other hand, it is grown in a container or pot, it is advisable to grow the plant in a rather shady area. In fact, the direct rays of the sun, especially during the summer season where the temperatures are particularly high, could cause the loss of the bright color of the flowers.


The large and vigorous stolons of this buttercup have no particular problems with regard to the soil in which they grow; usually they grow on the edges of ponds and shallow ponds, where the plant is submerged up to the collar, sometimes even the first leaves are submerged. Water buttercups particularly like still waters, so they are unlikely to develop in places with strong currents. This plant tends over time to form large colonies, so if you have little space it is therefore appropriate to keep the dimensions under control, removing excess plants every spring. As for watering, being an aquatic plant does not require special irrigation. It also supports stagnant waters very well and therefore it is not necessary, if cultivated in containers, to change the water contained in them periodically.


The multiplication of the ranunculus tongue occurs by division of the new plants that often develop alongside the old plants; in fact the stolons tend to crawl underground widening the original head and producing new plants; when they are of sufficient size the new plants can be detached from the mother plant and planted individually, buried on the edges of ponds or shallow ponds.

Water buttercup - Ranunculus language: Pests and diseases

Being an aquatic plant the Ranunculus lingua, like the other aquatic species, is rather resistant and bears well the attack of parasites. It does not develop particular diseases and does not require special care and attention. It is a very rustic plant that adapts to living better in the place where it is grown. In limited cases it can, however, be attacked by aphids, particular pests also called "plant lice" that infest numerous species.
