Clematis tangutica is a climber.


Clematis tangutica was already described and the name validly published by Carl Johann Maximowicz. It was Sergei Ivanovitsch Korshinsky, however, who reclassified it into todays valid botanical systematics .

The climbers are comparatively fast-growing and reach heights of 3,5 to 6 metres. The plants reach a width of 2 to 3 metres.


Clematis tangutica is deciduous. The dark-green, ternate leaves are opposite. The leaflets are lanceolate and petiolate. They have serrate margins and reticulate venation. They turn an attractive yellow in autumn.

Flowers and Fruits

Clematis tangutica produces solitary nodding, bright yellow campanulate flowers from June to September. The plants flower on this years shoots.

The climbers carry ornamental nutlets from summer to autumn.

Root System

The plants form shallow roots.


Clematis tangutica is native to West China and Northwest India.


The climbers prefer a sunny situation on moderately moist soil. The substrate should be sandy-loamy, gritty-loamy, sandy clay, loamy clay or peaty soil with a pH between 8 and 10. They tolerate temperatures down to -29°C (USDA zone 5).


The recommended planting distance is 60 to 100 centimetres, the climbers are best planted in groups of 3 to 5. Suited for rockeries, rooftop gardens and for beds and borders, as well as suited as groundcover and as bee pasture.

Maintenance and Propagation

The plants usually need very little maintenance.

  • Cut to within 20 centimetres above ground in winter.

Pests and Diseases

Honeydew, galls and distorted leaves are a sign for an infestation with aphids. Use an insecticide or control biologically , e.g. with parasitic wasps or predators such as Aphidoletes aphidimyza.

Root and stem lesions, often in combination with raised rings of bark and pustules nearby, indicate a fungal infection. Generously cut out and destroy affected parts.

Gnaw marks on flowers and leaves indicate in infestation with earwigs. Handpick and destroy pests and apply insecticide. Improve hygiene.

Leaf blotches are a sign of a fungal or bacterial infection. Bacterial spots are rather angular and yellow-rimmed while fungal spots usually are rather rounded with an area of fruiting bodies. Destroy affected parts, additionaly apply fungizide it is is a fungal infection.

A powdery white coat on the plants indicates an infection with powdery mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.

White tufts or white covering on the lower surface of the leaves indicates an infection with downy mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.

Distorted and discoloured leaves indicate an infestation with eelworms. Infected plants usually die and should be destroyed.

Brown, orange or yellowish pustules on shoots and on the leaves lower surfaces are very likely caused by a fungal infestation (rust). Remove affected parts and apply fungicide. Also improve ventilation and reduce humidity.

Scale insects that sit on the undersides of the leaves and excrete honeydew can be controlled with insecticide or biologically with parasitic wasps.
