Ulmus pumila (Siberian Elm)

At maturity, the Siberian elm is a big, fast-growing deciduous tree that may grow up to 50 feet tall with a vase-shaped to rounded crown up to 40 feet wide. The leaves are oval in form with a pointed tip and alternate. The leaves on either side of the leaf stem are 34-3" long, 13-1" broad, and even or nearly even at the base. They have a dark green top surface, are smooth on both sides, and have single toothed leaf edges. Early in the spring, before the leaves develop, the blooms appear in tiny crimson tinted clusters.
