Clematis 'Avalanche' produces clusters of glorious pure white 'male' flowers with yellow stamens. They are the largest blooms in this evergreen group of clematis. We recommend growing in a container unless the soil is free-draining or the drainage is very carefully improved.
Also known as x cartmanii 'Avalanche' and 'Blaaval'
Cultivation Advice
These clematis originate from species native to New Zealand and have attractive evergreen foliage. They are well suited to growing in free-draining soil or pots with free draining or alpine compost and may prefer the more sheltered places in your garden. 'Early Sensation' produces amazing seed-heads when grown alongside 'Joe'. These clematis are dioecious (producing either male or female flowers).
We recommend that you grow all the clematis in this group in free-draining soil or containers for the smaller cultivars and give them the benefit of a sheltered aspect. The compost for containers should ideally be very free draining and mixing in a few handfuls of horticultural grit or perlite will help. Make sure the pot can drain freely and reduce watering in the autumn because they over-winter better if slightly dry, rather than too wet. Perhaps consider planting in the spring.
