Olive trees in Gethsemane garden
The olive tree is native to the Mediterranean Sea region where it has been cultivated since ancient times. Growing to heights ranging from 10 to 40 feet (3 to 12 meters), the fruit is used as food and as a source of lamp oil. In Gethsemani, very old trees are to be seen. Knaggy and hollow as they are, the tourists puzzle over them.
