General tree description

Ulmus 'Sapporo Autumn Gold' is a widely planted hybrid elm cultivar, bred for resistance to Dutch elm disease. It originated in 1958 from crossing the Siberian Elm Ulmus pumila (female parent) and the Japanese Elm Ulmus davidiana var.

The tree usually forks at one and a half to two metres from the ground to produce a broad, round and densely foliated crown. Its bark is pale grey, and longitudinally fissured to form a random lattice pattern. Leaves are narrowly-elliptical, up to about 9 cm long and about 4cm wide. The stalk attaching the leaf blade to the stem (petiole) is about 8mm. The leaves turn pale yellow in autumn. Flowering usually begins when the tree is six years old and flowers appear in early March, followed by seeds in April.
