Features and characters of the individual

It’s difficult for a hazel tree to reach the rank of a “remarkable tree”. Most of them remain as shrubs and live for only 30–50 years. This leaves little chance of being part of the region’s living heritage. This tree is noteworthy for a tree of its kind though. Its foliage makes a nice crown with a diameter of 10 m. Soft green in spring and bright yellow in autumn, it provides shelter over a bench and enhances Parc Seny’s beauty. It is the first to bloom between January and March. First it is covered with male flowers, golden catkins, and then very small female flowers appear, which are star-shaped and bright red-pink. These become delicious hazelnuts that squirrels enjoy, and walkers forage for them when stopping at the bench too.
