Also called the sycamine, the black mulberry (Morus nigra) is mentioned only once, in Jesus’ statement to the apostles about their faith. (Lu 17:5, 6) The Greek word used was regularly applied to the mulberry tree, and the black mulberry is commonly cultivated in Israel. It is a sturdy tree that grows to a height of about 6 m (20 ft) with large heart-shaped leaves and dark-red or black fruit resembling the blackberry.
