Clematis 'Jackmanii'
late large flowered clematis (group 3)
Sumptuous, large, deep purple flowers with greenish centres from mid-summer to early autumn. This large-flowered clematis can be relied upon to produce a mass of velvety blooms with either 4, 5 or 6 petals from June to September. Ideal for growing in a large container, supported by trellis or garden canes, it copes well in a north-facing site.
How to care for Clematis Jackmanii:
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.
