Are pansies winter hardy?

Do pansies like sun or shade?
Light: Pansies do best with about six hours of sun daily. In warmest regions (Zone 7 and warmer), protect plants from full sun during the hottest part of the day. Too much heat can slow flower formation. New trailing pansy varieties, like Cool Wave, need a minimum of six hours of full sun to flower best.
