Under ideal conditions, oak trees live an average of 150 years, with short-lived varieties lasting 50 to 60 years and long-lived varieties living more than 150 years.
Some oak trees remain evergreen or nearly so, and frequently hail from warm, temperate regions with mild winters. Even evergreen oaks shed old leaves across the year, but younger leaves remain. Live oak, cork oak, canyon oak and Chinese evergreen oak are examples.
