Then warms up in the day time?
As long as the ground is not frozen you should be o.k. Not many perennials left around here and there will be less and less. Great buys on all plants though including trees. The key factor is protecting the root system from the freezing air temps. Plant as usual, maybe go a tad heavy on the mulch for the insulating value.
On a side note the Arbor Day Foundation ships trees out to our region only twice a year, very, very early spring and very, very late fall. A couple of years ago I was planting trees in early December.
In the winter the roots are the most vunerable part of the plant so as Green Pro said make sure the roots are protected from freezing to early.
Yes if you plant them early enough in the morning so the water that you put around the roots is well absorbed into the soil before it freezes that night.
Mulch heavily to prevent frost heaving of perennials.
It's a bit colder in your area than here in Oregon. Here, many nurseries have the plants sittiing in pots outside in the winter.
Planting in the ground would be as good and better than the nursery.
But you will be fine.
Just make sure that the plants you get, have not recently arrived from a warmer climate grower, which could mean they aren't yet acclimated to your area. That would be worth asking about.
A big problem is that it is hard to establish a good exchange of water between the parent soil and the backfill and then the root ball. Broadleaf evergreens planted very late are very vulnerable because the lose water through their foliage and are unable to replace it.
Use an anti-transpirant on them immediately after planting. It should make all the difference in the world.
What does that mean?
WiltPruf is the most well known brand name. Transpiration is the movement of water out of the leaves of plants. Anti-transpirants are usually a waxy liquid (looks and smells suspiciously like Armorall to me) that does not hurt the plant, but keeps them from losing excess water. Don't use it on things like colorado blue spruce or concolor fir. It will shine up the powdery film on the leaves which will take away their blue appearance.
This is also good stuff for transplanting. It does put a shine on the leaves for what that is worth.
An anti-transpirant is not going to save a plant that is not well watered in. It will help reduce winter dessication, but I would disagree that it will make "all the difference in the world".
