Confederate jasmine is not a jasmine at all. The vine belongs to the dogbane family alongside oleander and periwinkle, which the milky sap gives away at once, and the true jasmines sit in an unrelated family. The scent caused the confusion and is worth the misnomer: white pinwheel flowers in late spring, thick enough to cover the whole vine, throwing a perfume that fills a courtyard on a warm evening.

'Madison' is the selection to plant where winter bites, a hairy-leaved form of Trachelospermum jasminoides that has carried gardeners through zone 7 winters where the type gives up. Trachelospermum asiaticum 'Ogon Nishiki' is grown for foliage rather than flowers, new growth coming orange and gold and settling to bronze, and works as a groundcover as readily as a climber. All of them twine rather than cling, so give them wire, a trellis, or a railing to work with. Sun or part shade, and drainage.
