This is 'American Pillar' a Hybrid Wichurana (Van Fleet 1902). This is an amazing survivor of a rose that prospers in complete neglect.
It blooms only once per year and is one of the last of the once bloomers to get started. It's often in full flush on the 4th of July, American Independence Day. It's a little early this year.
It can be trained as a climber but really it does best when treated as a libertarian with no rules or constraints. Up to 4m tall!
