Valencia University Botanical Garden, in Spain, has a clematis with this label. The International Clematis Registrar writes "C.
flammula var. maritima is said to be a variety that is adapted to growing on sand-dunes around the Mediterranean. It is not recognised in
Flora Europaea and I do not know how (if at all) it differs morphologically from C.
flammula itself. When I compiled the Register I found no records of it being cultivated. But I suspect it should be treated as a synonym of C.
flammula - unless some other distinguishing character can be found."
Small, scented, pure white or creamy, star-shaped flowers borne in large clumps. Pale yellow or cream anthers.
