Hardy Rubber Tree Seeds (EUCOMMIA ulmoides) 5+Seeds
Eucommia ulmoides, commonly called hardy rubber tree, is typically grown as an ornamental shade tree because of its attractive glossy green foliage and its excellent resistance to insect and disease problems. It is native to China, but is possibly now extinct in the wild. It is a low-branching tree that typically grows 40-60’ tall with broad ascending branches and a rounded spreading crown. Dioecious with insignificant apetalous greenish brown male flowers (in clusters) and female flowers (solitary) on separate trees. Flowers bloom in April. Female flowers give way to flattened ash-like winged seeds (wings to 1.5” long). Serrate, elliptic to ovate, pointed, elm-like, glossy dark green leaves (3-6” long) remain attractive throughout the growing season. No fall color. As the common name suggests, rubber can in fact be made from the tree sap, but the extraction process is complicated and too costly for commercial application. Tear a leaf, break a twig or peel off some bark and a stringy latex-like sap appears.
