Callery pear?

I don't think I've ever seen one of those up here. USDA doesn't show it anywhere near either.

Pryrus was my thought as well.

Populus sp?

i thought poplar also ...

one might suggest.. that NOT everything you find growing gratuitously in a ditch.. is worth bringing to your garden.. lol ..

it will either grow explosively.. grow fast.. fast to disease.. fast to drop large limbs.. fast to die... [not to mention surface roots ]

or be a 100 foot cottonwood.. that chokes you with dusty seed for two or 3 weeks every spring...

i wouldnt plant one within 50 feet of the house ... well.. i did .. live and learn.. lol ... but dont tell anyone.. ok .. i would be embarrassed .. lol

all presuming its in the poplar family ....

ken

Ok-Ican go with that. Poplar is overwhelming around here.
But-could it maybe be Viburnum lentago?

Another view.

Not viburnum as the leaves are alternately arranged; Viburnum is opposite.
