Eucommia
ulmoides is a deciduous tree with a broad, spreading canopy and elliptical, rich
green leaves. It is the only hardy tree that produces rubber. Other trees that
produce rubber are tropical trees, like the rubber tree, a species of fig, and
the main source of natural rubber, Hevea brasiliensis. It 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 elm-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. As the
common name suggests, rubber can in fact be made from the tree sap. Tear a
leaf, break a twig or peel off some bark and a stringy latex-like sap appears. Shade
tree for lawns or parks. Street tree. Easily grown in average, medium, well-drained
soils in full sun to light shade. Best in full sun. Tolerates a range of soil
conditions. Hardy in zones 4-7.
