'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.
