Two mulberry species were recorded in Jordan: white mulberry (M. alba) and black mulberry (M. nigra). They have heart-shaped leaves with serrated margins and small, greenish-yellow flowers that produce berries. Cultivated white mulberry produces white fruit, while wild varieties produce purple fruit. Black mulberry produces dark-purple fruit. White mulberry holds the speed record in observed biology: the bent stamens spring out of flower buds at more than half the speed of sound, ejecting pollen into the air long distances.
Cultivated in urban gardens and orchards. Wild varieties occur in warm, sunny regions, including Jerash and Salt.
