These clematis prefer a good quality soil with high nutrient levels and a soil which is moist but free-draining. Improve planting holes with at least 2 forkfuls of well rotted manure or garden compost and if you don't have these use a 'Soil Improver' compost. The improvement material added should be placed under the root of the plant not around it. This encourages the roots to grow downwards and remain deep and cool during summer.There is no need to deadhead these clematis, however if they appear to have finished flowering earlier than you expected, there is no harm in giving them a light trim to encourage new growth and a secondary flowering late in the autumn.

A Clematis that is rarely seen in garden centres but is beautiful and something a little special

Never been to New Zealand but I bet its a gorgeous as this clematis.
