Clematis serratifolia

Clematis serratifolia, the Korean clematis, is a species of flowering plant in the family Ranunculaceae, native to Khabarovsk and Primorsky Krais of the Russian Far East, Manchuria, and the Korean Peninsula. A deciduous climber reaching 3 to 4 m (10 to 13 ft), in the wild it is often found growing in calcareous soils, but can handle acidic soil as well. As an ornamental it is grown for its citrus-like floral aroma and its fluffy seedheads, and is recommended for courtyards, walls, borders, and the like.
