Clematis x cartmanii hort. 'Joe'
Clematis x cartmanni 'Joe' is a fantastic evergreen clematis that can be grown in a pot or on a sheltered sunny wall.
It produces masses of pure white flowers with a pale yellow centre against a backdrop of dark green evergreen ivy like foliage. It is very easy to care for as it does not need any pruning unless you wish to neaten the growth in any way.
