Nenúfares (Nymphaea)
Besides making the garden ponds beautiful, the water lilies also help to protect the fish, providing them with shade and hiding places. They are also an important agent of filtering and providing oxygen to the water.
If you are looking for a water lily, here you will find a variety of them. You will be able to take home an adult plant with leaves and flowers in a vase with the necessary soil for its well-being. You will then just have to place the vase in the pond or in a big recipient with water.
