Clematis nepaulensis

Clematis nepaulensis

Habitat:

Filtered light position, ideally placed next to trees in order to provide a climbing frame and as shelter from the hottest times of the year. Soil needs to be well drained. This is because roots are quite fleshy.

Distribution:

Himalaya from eastern Nepal and northern India to Sikkim and Bhutan as well as Yunnan in south west China.

Hardy to:  -10 Deg C.

Flowering/Pruning:

C. nepaulensis is summer deciduous. Dormancy is broken around July and flowers start appearing early August and continue until October at which time it sets seeds and starts to shut down. Pruning/reshaping should be completed immediately after flowering.

Feeding/Cultivation:

Regular feeding during the growing season and summer months with a long term blood and bone and sulphate of potash mix (10:1) + foliar feeding using for example Powerfeed or a mix of Powerfeed and seaweed solution (3:1).

Description:

Strong climber to around 10m. Flowers are cream-yellow with the tip rolled or recurved. Stamens have prominent purple filaments. Foliage is glabrous and ternate. The long fluffy seed heads appear in November/December and are quite a sight.

Background:

This species was first described 1817 from specimens observed in the Himalayan foothills in Nepal. However, it was introduced from Yunnan in China by the scottish plant hunter George Forrest in 1912. At the time it was thought that the Chinese plant was a new species and it was therefore named after Forrest (Clematis forrestii). This was understandable given that species collected from the north western Himalaya region tend to have smaller and less flowers. However in time C. forrestii was considered to be a synonym of C. nepaulensis.

The unfortunate inclusion of a “u” in nepaulensis was probably down to the Swiss botantist A.P. de Candolle who was the first to publish details of this plant. We make this assumption because it is often listed as Clematis nepaulensis DC (Source International Plant Names Index). An interesting aside about this man is that he originated the idea of “Nature’s war”, which influenced Charles Darwin and the principle of natural selection. So perhaps we can forgive him for putting the “u” in nepaulensis.
