To your right is a walnut tree (Juglans regia). In many parts of Catalonia, it is common to find walnut trees planted at the sides of roads or around farmhouses, although around Lleida fields of them are also be found.
These trees have traditionally been planted for their many uses. The most important is for its fruit: walnuts, which are very good for preventing cardiovascular illnesses. It has also recently been said that they help prevent neurodegenerative illnesses like Alzheimer’s. Popular tradition associated the shapes of the leaves and fruit of plants with their medicinal functions, and in the case of walnuts, which resemble a brain, this rule which actually has no scientific basis, has turned out to be true.
