Summer and autumn-flowering clematis

These late-summer-flowering clematis are among the most popular and there are hundreds of varieties available. They look great grown through climbing roses or over shrubs, and are perfect for adding late-season colour. 

Looks

This diverse group includes the popular large-flowered hybrids that typically grow to around 3m high and have star-shaped flowers in shades of white, pink, blue-purple and red. It also includes smaller-flowering species clematis and their cultivars, like Clematis viticella and C. texensis, that have bell or tulip-shaped flowers on plants up to 4m high. C. flammula and C. rehderiana are prized for their clouds of small, fragrant, star or bell-shaped flowers. 

Likes

A sunny or part-shaded position in any deep, fertile, moist but well-drained soil. Clematis prefer their roots to be kept cool, so plant the base of the clematis in light shade or provide shading with other plants or a dressing of pebbles.   

Dislikes

Clematis dislike poor soils that dry out in summer and those that become very wet. Although tolerant of some shade, flowering will be disappointing in a very shady spot. 

Did you know?

The late-flowering Clematis tangutica and C. tibetana produce a mass of silky seedheads after flowering, extending the clematis season of interest into autumn and early winter.
