Christmas rose, also known as the Glastonbury Rose. This is a little white flower that grows in northern Europe during the winter. Legend has it that the Christmas rose is of miraculous origin. As the Christmas rose represents purity, it has often been carved into confessionals as a five-petal flower: the penitent walks in a guilty sinner, and out with their purity restored. It also appears in plenty of medieval heraldry, among other uses.
