Bearing the namesake of a founding member of the Clematis Society, ‘John Howells’ stands tall as a vigorous climber with lush mid-green leaves providing the perfect backdrop for the star-shaped flowers that emerge in a rich carmine hue with brighter red bar and deep wine-red anthers. With a neat and charming habit, this clematis is an extremely floriferous cultivar, adored for its captivating blooms and compact form making it ideal for containers, as well as border obelisks and arches.


  • Garden care:
    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.

    Choose a spot with well-drained, fertile soil and ensure the location receives plenty of sunlight—at least 6 hours a day—for optimal flowering.

    However, they prefer their roots to be cool and shaded, so plant low-growing plants or add a layer of mulch of well-rotted compost around the base, avoiding the immediate crown.

    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.
