How hardy is this rose? I see it listed as Zone 7. I know there is
one at the National Arboretum in DC but they are slightly warmer than
I am. Has anyone grown this rose successfully in Zone 6a or further
north?

In theory Mutabalis is a China rose, which makes it possibly hardier
than tea-based varieties. It would be worth a try in Zone 6.
