Hardy rubber tree

From central China. Rubber can be made from this tree's sap, but the process isn't economically feasibleinstead, the plant is grown for its ornamental qualities. Attractive rounded habit; can reach 4060 feet tall, with equal or greater spread. Leaves resemble those of elm (Ulmus) but are glossier and more leathery. When a leaf is slowly torn in two, sap from the veins congeals into threads of rubber, holding the two halves together. Tolerates a wide variety of soils but requires good drainage. Not troubled by pests. 'Emerald Point' has a more upright, narrow, oval habit and smaller leaves. Useful street tree.
