Ulmus x 'Frontier'
I'm considering this plant for an area in which I want an airy texture but have a couple questions I can't seem to confirm.
The US National Arboretum who introduced the tree says its hardy to zone 4 but all other sources state zone 5 so I'm wondering if its not as hardy as expected. I'm thinking it will be fine during a rough zone 5 winter.
The fall color appears to develop late. Does it have any resistance to late freezes? I feel like every other fall hard freezes arrive in early to mid October and zap many trees before they can develop any appreciable fall color. Not surprising, the natives around here have no problem...ie oaks and maples. Its more the exotics or natives that inhabit areas like the east.
