Celtis Sinensis is a spreading, deciduous tree native to E. China, Korea and Japan where it reaches heights of around 12metres in woodland areas.
Visually similar to Zelkova serrata, Hackberrys have a very fine twig structure which carries glossy,blunt-toothed, dark green leaves to 8cm long.
Small green flowers are borne in Spring followed by small, sweet, edible fruit which are a dark-orange ripening to red-brown.
Rarely seen in the UK, Hackberrys are a fairly commonly used species in America and Asia where hotter summers are beneficial to vigorous growth.
