About 'Sylvia Denny' Clematis:

'Sylvia Denny' flowers beautifully and profusely with semi-double flowers in summer and again with single ones in September. These pure white rosette blooms are a true classic originating in Lancashire.

Perfect for container growing and spectacular against a dark background or on walls, arbors or pergolas, it's fully hardy and has a compact growth form.

If you are looking for larger, more rambling clematis take a look through our collection.

Great for your garden:

'Sylvia Denny' will be happiest in alkaline or neutral soil and will do well in full sun or partial shade in any aspect. It is vigorous and fully hardy, and flowers profusely, with only light pruning required.

This clematis is fabulous for setting off against dark hedges such as holly or yew. With a compact habit, it is contented in containers and so could be used for a more formal effect than a rambling clematis. You could shade the base with other low growing plants.

  • Look out for:

    Clematis slime flux. Its an uncommon bacterial infection but can be fatal. It happens when the plant has an injury and bacteria infect the wound. Signs include wilting and yellowing of the leaves, as well as the unpleasant slime in the stems where the plant is affected.

    Earwigs, aphids, and fungal infections can also affect Clematis


    Trivia:

    The Denny family are a kind of clematis dynasty based in Lancashire. There are a whole series of clematis named after local towns and family members. This particular one was named by Stephen Denny. Sylvia and Vince Denny started the nursery and named other cultivars after their grandchildren.
