From personal experience, I can state that they easily live beyond 80 years in California's San Francisco Bay Area (trees planted in front of my grandmother's home are among the oldest in the Alameda County). These trees were identified by county as among the oldest in the county, and now are on the tail end of their lives. I'm guessing that they may have another 15-20 years with very careful tending. They have survived an invasive psyillid invasion (Calophya rubra aka peppertree psyllid)

in the 1980s, but now thriving, though with large hollows and incipient tree fungus. The trunks are about 3.5 feet and 4.5 diameters, and the tree heights are probably about 20 feet. One tree is particularly wide at roughly 25 feet, the other is more like 18 feet. Because of their age, they are rich havens of urban wildlife, with frequent woodpecker nesting and when in bloom busy insect and bird activity.
