Elm Collection
Our wonderful midwestern and eastern street tree, the American elm, (Ulmus americana) has been nearly exterminated because of Dutch Elm disease.  Though there are several elms that are less susceptible to the disease, Siberian elm, (Ulmus pumila), and the closely related hackberry (Celtis occidentalis) there has yet to be a disease resistant elm with the beautiful arching gracefulness of the American elm.  We continue to add cultivars to the collection which are supposedly resistant.  To date we have not lost any of the "resistant" cultivars.  ‘Accolade' is one of the better hybrids.  I sometimes call the elm collection the ‘stump collection'!
