Clematis buchananiana

Clematis buchananiana

Habitat:
This species comes from a temperate rainforest environment, making it important that the the soil  never dries out. Its preference is it sit in part shade but can be planted in full sun in temperate regions. It is a plant that is quite vigorous (take over merchant comes to mind) therefore gve it plent of room. Unless you need to cover a shed, this one is not a for a small garden.

Distribution:
Himalaya, from Kashmir across to the northern region of Vietnam.

Hardy to:
-12 deg C

Flowering/Pruning:
This species is late flowering. (end of summer). While it can be left unpruned, it will soon become bare at the base and flowers will be produced well above head-height. This is ok if you need it to cover a fence and you can under plant it, but for general use pruning is recommended. In March, prune all stems back to approximately 50cm  from ground level, cutting just above an old leaf joint. New growth will soon appear, resulting in a plant which is green from top to bottom and with flowers at a more acceptable height.

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:
The plant produces small, nodding scented flowers that are usually creamy white or pale lemon, with tepals slightly upturned. Leaf margins are serrated or saw tooth like and pinnate.

Historical Background:
Our research indicates that this species was introduced in 1812 and although yet to be confirmed was named after Francis Buchanan (1762 – 1829). FB was a medical practitioner from Scotland who made significant contributions as a geographer and botanist while living in India. He succeeded William Roxburgh to become the Superintendent of the Calcutta Botanical Garden in 1814, but had to return to Britain in 1815 due to his ill health. More research is needed.
