My snapdragons have been known to survive the winter from time to time. I have two snapdragons that survived this year. One was planted in a self-watering planter with daylilies. The other is in a small plastic pot I got from a nursery. I'm really surprised that one survived but it was surrounded by other similar pots all placed in a grow bag. We also had an extremely mild winter. They are getting buds now. If I can remember I'll take some pictures and post them. The plants don't look all that great though but since I didn't grow any from seed this year I'm happy they survived.
