Clematis viticella is a deciduous climber with attractive open bell-shaped purple flowers from late summer to autumn.
For best results choose a spot where the roots are in the shade and stems get at least 6 hours sun a day. More sun equals more flowers.
The woody stems climb by winding their twisting leaf-stalk tendrils around the support they are growing against.
Clematis give the garden a cottage feel and can be grown successfully to cover fences, arches, sheds and walls.
