A graceful, medium-size tree with a dense round crown. The tree usually grows to 8 - 15 m but in exceptional cases it can reach 18 m tall. The young twigs are glossy brown and slightly hairy, but rapidly become hairless. The old bark is brown-grey and peels off in small plates revealing the orange bast. The leaves are fairly small and glossy dark green. In southern regions of origin, the tree is almost evergreen but in a temperate climate always deciduous. The foliage falls in late autumn and takes on hardly any or no autumn colours. The tree blossoms in September with clusters of inconspicuous green flowers, followed by winged seeds. Its resistance to Dutch elm disease makes it worth considering as a park and avenue tree. It has a great adaptability to various soil types, tolerates a lot of warmth and is wind resistant.
