The really hardy Pyrus Ursannis or Harbin pear seem to be Canadian suppliers that do not ship to USA . So can anyone tell me what common pears grow there . Are flowering pears grown there ? This would give me a idea of what really can grow there .
I have a book of trees that are available across the us from different nurseries// here is a small list // I got tired of typing all the zone 4's there are more.. //I would call the university of minnesota and see if they could tell you where to get some trees , I don't know if they stil do a lot of pear research but they seem to be on top of things// they have an agricultural extension office http://www.extension.umn.edu/agriculture/
beierschmitt is from iowa - hardy to zone 4//
beurre hardy is french -hardy to zone 4
