-This tree used to be considered one of the two most important timber trees of China, and most Chinese homesteads had one or two of each planted nearby. They were also very important for the production of silk. The expression "Sang Tzu" means "Land of the mulberry and catalpa" and it's still a common phrase in Chinese meaning in "home" or "homeland".
-This species of Mulberry is fruitless and therefore does not make a mess when planted in urban areas. This in addition to its ability to survive drought make it one of the easiest plants to care for because it does not need much. The tree is dense and broad and therefore gives a lot of shade. Although the fruitless mulberry does not create messy fruits it does shed leaves during the fall. The buds of the mulberry also can create messes.
