Picture from Dutch wiki:


Many clematis species have a very nice smell, and both the flower and the fruit are also nice to look at. That is why clematis species are grown in garden often, with countless varieties. They differ in color (most are white, pink or purple), in flower size and in flower time (spring/summer).
