Q.Can I Plant A Wintergreen NOW?
I received a very pretty wintergreen plant The daytime temperatures have been in the low to mid 30’s F (30to 36 degrees) and into the 20’s at night. Where I want to plant it is near a house, but it will get morning shade an hot afternoon sun in the summer. It is probably 2-3 quart size in a metal pot, and with lots of berries, perhaps potbound. I don’t get a lot of sun in my apartment. Basically I just want to know if I can go ahead and put it in ground right now since the ground is not frozen? Thank you.

No. It is too cold right now. Your plant's roots need time to become established before it is subjected to freezing temperatures, which would likely kill the plant.
Hold it over till after the last frost date in your area. You can keep it in a cool room in your home or in a basement or garage that stays above freezing. Water sparingly, just enough to see it through till spring.
