Well, "small" can be relative. How big are they (in feet or inches) and how long have they been in the pots? If they have a good-sized root system, that would be good for planting. If they are just a few inches tall, I would prefer to overwinter them in a garage and plant them 2-3 weeks after your last date of frost in Spring 2016.

Plant them. Surround them with chicken wire and fill that up with dry leaves around Thanksgiving. They'll be fine. If you have rabbits like mine are here, you'll need the chicken wire every winter.
