Pruning regularly will ensure that you can enjoy flowers at eye level, rather than them all appearing towards the top of the plant. It will also prevent a tangled mass of stems.
Here are 10 beautiful Group 3 clematis to grow.
Clematis viticella 'Kiev'
Clematis 'Kiev' was bred in Ukraine and named after its capital city. It boasts dark green leaves and long stems bearing dark, velvety purple-red flowers with yellow filaments and purple anthers.
Clematis x durandii
Clematis x durandii bears deep blue, saucer shaped flowers. Unusually, it is a semi-climbing perennial that needs staking. Grow it as a border plant, trained up an obelisk or trellis, or in a container.
Clematis texensis 'Princess Diana'
Sometimes known as 'Princess of Wales', Clematis texensis 'Princess Diana' bears bright pink, tulip shaped flowers in summer.
Clematis viticella 'Emilia Plater'
A vigorous climber, Clematis viticella 'Emilia Plater' will quickly cover a large wall or fence; grow it up a sturdy obelisk or let it scramble through a tree.
Clematis viticella 'Entel'
Clematis viticella 'Entel' bears lots of medium-sized, pink flowers with wavy edges from July to September. Grow it up an obelisk in the border, or use it to cover a fence or wall.
Clematis viticella 'Etoile Violette'
This classic viticella clematis bears masses of purple flowers in July and August. It looks good scrambling over a fence, up a tree or through a rambling rose.
Clematis viticella 'Hanna'
Like many Viticella clematis, 'Hanna' has bell-shaped, nodding flowers. This free-flowering and vigorous climber reaches around 300cm in height.
Clematis viticella 'Jorma'
The flowers of Clematis viticella 'Jorma' are large, and deep purple-blue with yellow-green anthers. Grow it up a pergola or sturdy obelisk in a large herbaceous border, or as a companion to climbing and shrub roses.
Clematis viticella 'Kermesina'
