Codonopsis convolvulaeca

Codonopsis convolvulaeca

The name Codonopsis is derived from Greek “kodon” (bell) and “opsis” (appearance), from the shape of the flower.

Codonopsis are found in the mountains of Cental Asia, Korea and Japan.  Some species have long thin stems that climb through low shrubs. Other species form low, sprawling shrubs, or climb weakly by simply draping themselves over branches. The flowers vary from star shaped to bell shaped, their colours range from white, cream, light greens, light to dark blues, reddish purple to black, often with a combination of these colors. From our experience they seem to do best in partial shade, but will take full sun if their roots remain cool (As per Clematis). They all prefer well drained soil and where winters are wet, a sheltered position with a dry mulch is recommended.

It must be mentioned that the leaves of Codonopsis often smell like cat urine when you rub them. (Ed: why rub them!) So this is a plant for people who like growing Arums and  will tolerate the stink for the sake of beauty.

Codonopsis is sometimes referred to as “poor mans ginseng”. It is said that codonopsis produces nutritive tubers that lend themselves to being included in cooking and medicinal preparations.  For example Codonopsis is often added to soup to enhance the health benefits of the soup but it also makes an excellent meat substitute. In Oriental medicine, codonopsis is used to treat yin deficiency conditions and increase precious qi. This makes it useful for those who are tired or suffering from chronic fatigue. It also helps to reduce the risk of peptic ulcers. The Chinese prefer to use Codonopsis pilosula in medicine; but Koreans favor Codonopsis lanceolata or todok. Both are edible.


Parts of south west China (Yunan), Bhutan, Northern Myanmar and Nepal.


Herbaceous climber to around 2 metres, with stem being much-branched. Leaves alternate, lanceolate, narrow-lanceolate or lanceolate-linear. Flowers terminal or axially, lower part of pedicels with 2 leaf-like bracts; colour blue, shape is broad campanulate.


The German botanist Wilhelm Kurz (1834-1878) is recognised as being the first to use this name. Interesting chap Mr. Kurz. References are consistent in referring to young Wilhelm having some sort of disagreement with his family, decided to leave Germany and sailed to Java and entered the Dutch service, in which he stayed for several years. In 1864 he was persauded by Thomas Anderson, who was visiting the Dutch colonies, to return with him to Calcutta (now Kolkata) as curator of the herbarium, a post he held till his death in 1878.
