Clematis cirrhosa varieties are Evergreen types that flower through the winter months, cirrhosa cultivars are mainly nodding making a sort of 'hood' shape rather than a 'bell' shape. Their foliage is still quite substantial and forms a good screen with good coverage. cirrhosa varieties are fully hardy and will flower very well if given some sun or alot of sun. They provide essential pollen for our bees and butterflies community too :-)
