A tree native to southern Europe the Field Elm (Ulmus minor) has a wide range of subspecies and hybrids. The images in this post come from two different trees. The first is of a mature Field Elm was photographed in the "Quinta del la fuente del Berro" botanical park in Madrid. The second is a young Field Elm in the botanical garden of the University of Malaga.
These trees are quite commonly used in Madrid as an urban tree that can be found along many streets and avenues.
While the native range of this tree is southern Europe it can be found in natural habitat as far away as Asia minor.
The Field Elm can grow quite large. The image above from a botanical park in Madrid is of a tree that has a trunk about one meter in diameter.
