about 2/3 of the day, and will be buried in snow for 3 months out of the

Gorse, common hawthorn, or sloe would do it. Also probably some of the
hedge roses, or bois d' arc if you prune it into a shrub form.

I'm not sure if honey locust can be grown as a shrub.

Best regards,

Watch out for gorse, it can become a major pest. It's officially a
noxious weed in many places.

Barberry and pyracantha are both good. Pick a fireblight-resistant
pyracantha. If minor cruelty to animals doesn't disturb you, birds
pigging out and getting drunk on pyracantha berries can be amusing.
