Early (April – May) flowering evergreen clematis with glossy finely divided leaves and masses of 7.5 cm (3″) white flowers with green centers. Supposedly scented, I couldn’t smell anything from the flowers. Some people say the whole plant has a citrus smell but again I couldn’t get anything.
Grows to about 2 meters and can be grown in a large pot. Requires a west or south facing wall with protection from wind. You can grow it up trellis or as just let it sprawl.
