Broussonetia–commonly called paper mulberry–is a deciduous shade tree grown for its fast growth and dense, broad head. It grows to 25 feet (8m) tall and wide and often larger. Broussonetia tolerates pollution, heat, and poor soil. It is popular in urban locations.
Broussonetia’s leaves are gray-green, ovate to deeply lobed, and grow to 8 inches (20cm) long. Broussonetia bears pendent catkin flowers in spring. Female flowers have slender purple stigmas and produce spherical heads less than an inch across that develop into mulberry-like, sweet-tasting, orange-red fruit in autumn.
Broussonetia gets the common name from its inner park which is used for making paper and Polynesian tapa cloth.
Broussonetia is a genus of seven species of deciduous trees and shrubs native to East Asia and Polynesia.
