Clematis tangutica 'Bill Mackenzie'

Clematis tangutica Bill Mackenzie is a large, vigorous climber which dazzles with a summer abundance of modestly sized, bright yellow nodding flowers over your wall, trellis, hedges or trees. 
A later flowering variety, this is a great choice for adding interest to the garden in the waning summer and autumn months. With fine cut leaves and thick curled back, bell-shaped flowers, stiff like orange-peel, they are real charmers. The flowers go on to become delightful very large feathery seed heads for the rest of the year.

Did You Know?

Also known as 'orange peel' clematis, for its thick, curled flowers. It was created by Valerie Finnis (1924-2006), a renowned plantswoman (and an exceptional plant photographer), and is a cross-breed of Clematis orientalis and Clematis tangutica

Finnis named the cross after her 'great friend and mentor', Bill Mackenzie (1904-1995), who was Curator at the Chelsea Physic Garden. He had spotted an unusually vigorous seedling during a visit to the Waterperry Horticultural School for Women near Oxford, where Finnis studied and then worked. They shared a love of Alpines.
