Olive plants (Olea europaea) require certain growing conditions, but they are capable of living for a very long time. In fact, The Science Times reports that olive trees around the world can live as long as 1,500 years, with an average life span of 500 years.
But:
The Olive tree of Vouves in Crete, Greece is probably the oldest olive tree in the world and it still produces olives. It is confirmed to be at least 2000 years old based on tree ring analysis, but it's claimed to be between 3000–4000 years old!
