The Zelkova

The Zelkova -  is a deciduous tree in the Elm family that is native to Europe and Southeast Asia.  It is susceptible to Dutch Elm disease but most often survives it, this is one of the main reason why it is considered to be a replacement for the Elm tree.   With a vase shape and the ability to grow 90-100 feet tall with a 60-80 foot spread.  It has a moderate growth rate and thrives best in full sun locations.  


The leaves are 1 1/2 to 4 inches long, green when young and turning a brilliant orange to burnt umber in the fall.  This varities crown grows naturally in a vase shape very similar to that of the Elm.   The leaves are a simple shape with serrated edges.  There are not obvious flowers on this tree they are very small and inconspicuous.


The Zelkova grows in a variety of soils but prefers moist deep loams.  Established specimens are highly drought resistance.  This tree makes for an ideal street tree as they thrive even in pits that were they soil is restricted.  It also has a high disease and salt resistance.
