If you have room for a bigger tree, consider the Cork Oak (Quercus suber). This species does very well in San Francisco because it’s adapted to the Mediterranean climate and tolerates drought. This stately, spreading evergreen provides comfortable shade on sunny days.

The Cork Oak is named for its thick, insulating bark, which is the centuries-old sustainable source for bottle corks. Starting when the tree is 25-30 years old, cork can be harvested without harming the tree.

This tree can live for 150 years or more, making it a wonderful choice for a lasting contribution to San Francisco’s urban forest. Thanks to its moderate growth rate, you won’t have to wait too long to enjoy it.
