Landscape trees for a villa courtyard should be chosen for their aesthetic appeal, compatibility with the local climate, and suitability for the courtyard space. Popular choices include evergreen trees like the Japanese maple (Acer palmatum), cherry blossom (Prunus serrulata), and evergreen magnolia (Magnolia grandiflora). Deciduous trees like the ginkgo (Ginkgo biloba) and cherry (Prunus avium) provide seasonal interest. It is also important to consider the tree's growth habit, size at maturity, and maintenance requirements.
