Clematis patens 'Hagley Hybrid' is a compact, free-flowering climber prized for its abundant, shell-pink blooms with contrasting reddish-brown anthers. It flowers reliably from early summer into autumn, making it a dependable choice for trellises, arbors, and container growing.
Best grown with its head in the sun and its roots in the shade, this clematis benefits from a cool root run achieved by mulching or underplanting. As a member of the large-flowered hybrid group, it blooms on new growth and responds well to hard pruning in late winter to encourage vigorous, well-shaped plants.
Clematis Wilt
Sudden wilting and blackening of stems and leaves, often just before flowering. Whole shoots collapse rapidly while roots remain healthy. Caused by the fungus Calophoma clematidina.
Cut affected stems back to ground level and dispose of them, not in compost. Water at the base to keep foliage dry, improve air circulation, and plant the crown deep so the plant can regenerate from below soil. Apply a fungicide if the problem recurs.
Powdery mildew
White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.
Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.
Aphids
Clusters of small soft insects on new growth and flower buds.
Knock off with a strong jet of water. Ladybirds and lacewings are natural predators. Insecticidal soap as last resort.
Spider Mites
Fine stippling or bronzing on leaves, faint webbing on undersides, foliage drying out during hot, dry weather.
Spray foliage with a strong jet of water to dislodge mites. Apply insecticidal soap or horticultural oil to leaf undersides; repeat every 5–7 days as needed.
