Looking for a hardy tree that thrives in poor soil and urban environments? Look no further than the Paper Mulberry, also known as Broussonetia papyrifera. Native to eastern Asia, this deciduous tree is known for its variable leaf shape and yellow-green foliage in the fall. But this tree is more than just a pretty sight - it has been cultivated for centuries for its fiber, used for papermaking in China as early as 100 AD and to produce tapa cloth in Pacific Island nations. The paper mulberry also bears red fruit which is edible, and its bark, fruit, and leaves have been used in traditional medicine. However, be aware that the paper mulberry can spread rapidly and become invasive, particularly in disturbed areas where it can form dense stands. But with its ability to tolerate pollution and disturbance, it's also a favored tree for landscaping and reforestation efforts.
