What is the lifespan of Osmanthus? A client’s 20-year-old, 12 ft. tall shrubs were once a hedge that one was unable to see through, but have become a walk-through wall these past couple of years.
According to SelecTree, a database produced by the Urban Forest Ecosystems Institute, most Osmanthus species have a longevity of 50 up to 150 years. A plant’s lifespan varies, and urban trees and shrubs tend to be subjected to more interventions in the form of pruning, pollution, damage from construction, and so on. Also, the hedge has undoubtedly become woody with age.
