Evergreen foliage is shady all year.

Gardening was easier before suburban lifestyles became so passe. Now, larger modern urban homes occupy smaller urban parcels. Modern fences are taller to enhance privacy for such densely situated homes. Garden space is both minimal and shaded by so much infrastructure. Ironically, shady evergreen foliage is now more practical for such gardens.

Deciduous trees are still practical for single story suburban homes on suburban parcels. They provide cooling shade for summer, and allow warming sunshine through for winter. Smaller evergreen trees and shrubs closer to fences obscure unwanted scenery beyond, without shading homes during winter. Such strategy is facilitated by sufficiency of space.

It is not so practical for confined and modern urban gardens though. Space is insufficient for big deciduous shade trees. Smaller trees can not get tall enough to shade roofs of tall modern homes. Insulation of modern homes is fortunately so efficient that summer shade and winter sunshine are not as advantageous as they still are for older suburban homes.

Therefore, most trees in modern home gardens primarily obscure unwanted scenery and provide privacy, rather than merely provide shade. Not only should they be proportionate to their gardens, but such trees should also retain evergreen foliage as low as the tops of associated fences. Some of the more practical options are actually evergreen shrubbery.

Large evergreen trees, such as Southern magnolia, California pepper, camphor, various palms and some eucalypti, are too big for some confined modern home gardens. English laurel, New Zealand tea tree, hopseed bush, various arborvitae, and particularly various pittosporum function as small evergreen trees that are proportionate to confined gardens.

As practical as evergreen foliage is for modern urban home gardens, it requires as much maintenance as other forms of vegetation. Contrary to common belief, evergreen foliage sheds. It is just sneaky about doing so slowly throughout the year. Additional foliage also innately adds shade to already shady situations, which can complicate other gardening. To become compact evergreen trees, shrubbery requires directional pruning.
