Regular snapdragons often overwinter for me, they seem to actually be tender perennials, or even subshrubs (I prune them like a Caryopteris, to about 6", every spring.
But I also have a Antirrhinum hispanicum 'Gummy' that lives on the edge of a rock wall. It blooms all summer, and even survived our 10 degree F weather this last winter. It is a creeper/sprawler/dangler-over-wall-edge kind of plant, not a spike like the usual snapdragons.
