elm tree developed by U of M or arboretum
I know the university did a lot of work testing the hardiness to disease of a variety of elm. I have forgotten the name of the variety. I know that you have also done a lot of testing of the different varieties that are available but I am looking for the Minnesota variety.
Ramsey County Minnesota
Thank you for contacting AaE for help.The closest that I can find is Ulmus 'St. Croix'. The Minnesota Arboretum has a collection of hybrid and american elms. Their site states that Ulmus 'Accolade' seems to be the better hybrid.
I hope this helps.
Look at our University of MInnesota Extension publication on DED resistant Elm trees at: z.umn.edu/dedrtrees. Chad Giblin is the UM specialist researching DED Elms. firstname.lastname@example.org feel free to contact Chad.
