Clematis flammula

About

Clematis flammula, the fragrant virgin's bower, is a species of flowering plant in the family Ranunculaceae. This deciduous climbing plant is native to southern Europe and northern Africa, but it is cultivated worldwide as an ornamental plant in gardens. It bears fragrant white flowers and small green achenes. When the flowers are newly opened they have a strong sweet almond fragrance. Clematis × aromatica, the scented clematis, is the result of a cross with Clematis integrifolia.
