Morus alba
A weeping cultivar of white mulberry, "Morus alba" 'Pendula', is a popular ornamental plant. It was planted at several grand stations built along the Lackawanna Railroad in New Jersey during the late 1800s and early 1900s. The species has become a popular lawn tree across the desert cities of the southwestern United States, prized for its shade and also for its cylindrical berry clusters composed of sweet, purplish-white fruits. The plant's pollen has become problematical in some cities where it has been blamed for an increase in hay fever.
