Clematis Proteus Plants

Proteus is a large flowering clematis with pale dusky pink-purple flowers in early summer, then again in late summer to autumn. The blooms are big, at around 15cm in diameter, and tend to be double or semi-double in the first flush, then single for the second. It's happiest in a bit of shade, and will even cope in full shade, so makes a brilliant climber for a north or east-facing border, grown up an established tree or shrub, or given a sturdy fence or pergola to clamber over.

Growing Proteus Clematis

Like most coloured clematis, it is happiest in light shade, as full sun tends to bleach the flowers. They're big once mature, so make sure they have room to climb – either through a mature tree or shrub, or up a pergola or trellis-covered fence. Plant in spring or autumn, a couple of feet away from the fence, digging in plenty of garden compost or leaf mould and burying the crown of the plant 5-8cm below the level it was at in the pot. This will encourage strong new shoots from the base of the plant. Once planted, water in well and, if the base is going to be bathed in sunlight for most of the day, cover the soil around it with pebbles or small stones for shade and protection to ward off clematis wilt.

This is a group 2 clematis, so with new plants, prune hard to 30cm above ground level in February the first season after planting. Thereafter, prune once in February, removing any dead or damaged stems, and pruning to healthy buds to create a framework in the desired area. Then prune again in mid summer, to encourage a second flush, to a strong bud or side shoot just behind each spent bloom.

Keep clematis well watered, especially while establishing in the first year; they hate to dry out.

Planting Companions for Proteus

A large evergreen shrub makes a great support system for clematis; choisya will coincide with Proteus' first flowering, producing a lovely white and purple effect all over the bush. If you're planting this way, always plant your clematis on the north side of the host tree or shrub, as it will naturally make its way through towards the sun.

Combine with other clematis varieties for an explosion of colour and form. Try dark purple Daniel Deronda and bright pink Doctor Ruppel, which will flower simultaneously.

Did you know?

An old cultivar dating back to 1876, one of Charles Noble's many contributions to the clematis party. The parents were Clematis viticella Grandiflora and Fortunei. Its other name is The Premier.

Proteus was a Greek god of rivers or seas, known for his adaptable ways, and the English word protean is derived from this characteristic.

Clematis is a genus of more than 200 species of plants, some of which are evergreen, others deciduous. They all climb by twining their leaf stalks around their support. There are more than 400 different cultivars to choose from. In fact, they say you can grow a different clematis that will be in flower for every month of the year in the UK.

Clematis petals are, in fact, sepals, the part that encloses a flower. Hence, you can often find a green strips, or very occasionally some of the petals will revert and become green.

The flowers of clematis vary in size from 1-2cm to 20cm and come in a fabulous range of forms. These include singles, doubles, viticella (four petalled), saucer-shaped, star-shaped, bell-shaped, tulip-shaped and tubular.
