Product Information
'Sylvia Denny' is a beautiful large flowered deciduous climber that will not fail to impress. Made up of double, semi-double and single blooms, this is a clematis that will certainly provide an impressive display throughout the summer months.
This clematis blooms all the way along its stems, resulting in a proliferation of large, pure white flowers from the ground upwards, starting in May and June, and then once again during late August and September. The second flowering consists of smaller single blooms. This climber is a beautiful feature for fences, trellises, and arches and is especially effective in containers.
‘Sylvia Denny' will thrive in a sunny spot, where it can be trained up trellis for a vertical wall effect or allow to naturally wind its way through beds and borders. Easy to maintain, you just trim the stems back to 15cm (6in) in February or March.
Supplied as an established plant in a 9cm pot, ready for planting.
What Is Supplied
Top Tips
- Plant with the crown of the plant 5-8cm deep to encourage new shoots to grow from below ground level. Clematis like a cool ‘root run’ so try and plant so that the roots are shaded. If you are planting in a sunny position, place some pieces of slate or flat stones on the soil after planting or use groundcover plants to keep the roots cool.
Care Information
- Feed in spring with a general-purpose feed, avoiding the stems. Mulch immediately afterwards with organic matter such as well-rotted manure, leafmould or garden compost.
- Water regularly during periods of dry weather in the first few seasons after planting, especially for container plants.
- Clematis in pots should be given a liquid feed through the summer and early autumn.
- Flowers appear on new growth, so cut back all the previous year's stems to a pair of strong buds, 15-20cm above soil level, before growth begins in early spring.
