This vigorous, late summer-flowering clematis produces a profusion of crimson red flowers from July to September. Named after the kermes insect from which the red dye cochineal is obtained, the scarlet flowers look magnificent scrambling through trees, shrubs and climbing roses. Resistant to clematis wilt, it copes well in moderate wind.
How to care for Clematis Kermesina:
To avoid dry conditions, and to ensure good soil contact around the rootball, we advise planting climbers at least 30cm (12in), and preferably 45-60cm (18-24in) away from the base of a wall or fence. An even larger distance should be maintained when planting climbers beside an existing tree or shrub.
In early spring cut back the previous year's stems to a pair of strong buds about 15-20cm (6-8in) above ground level and apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the plant, avoiding the immediate crown.
