Both the species and the double flowering variety prefer part shade position and soil that includes gravels of various sizes. Whilst it is called a climber, it actually has more of a scrambling habit. So give it something to scramble through.
The species comes from the mountains of central and southern Europe.

Flowers appear in late Spring from the previous year’s growth. Any pruning should be done immediately after flowering ceases. This will enable new growth to establish before the end of the growing period. Late pruning will result in very few flowers the next season.
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).
Deciduous climber to 2-3 metres with biternate lance shaped leaves. Flowers nodding, lantern shaped, slightly spreading. Flowers range from shell blue to white.
The species was introduced into the UK from Europe in 1792, although some references state is was earlier (1768). Remained very popular ever since.
Raithby will be listing this species in 2017. There are many single and double flowering hybrids available from well known suppliers; Clematis Cottage in Tasmania and Alemada Homestead Nursery in Victoria just to name two.
