Clematis Henryi

Clematis 'Henryi'

Clematis ‘Henryi’ is a distinguished, long-admired clematis variety celebrated for its pure white, large-petaled flowers and dramatic dark stamens. Blooming first in late spring and again in late summer, this cultivar delivers two generous flushes of blooms that add light and elegance to any garden setting. Each flower, often 6–8 inches across, creates a striking contrast against the plant’s rich green foliage, making ‘Henryi’ a standout feature on trellises, arbors, fences, or pergolas. Its clean, classic look allows it to pair beautifully with roses, dark-leaved shrubs, and other flowering vines.

This clematis thrives in full sun to partial shade, though the pure white petals maintain their best color when protected from intense afternoon sun. ‘Henryi’ is known for its strong, reliable performance and moderate vigor, making it suitable for both beginner gardeners and experienced clematis collectors. Its refined appearance and repeat-flowering habit ensure it remains a highlight in the landscape from spring through early fall.

Care Instructions

Planting

Plant in full sun to part shade. Provide sturdy support such as a trellis or arbor. Keep roots cool and shaded with mulch or low-growing plants. Use nutrient-rich, well-draining soil.

Watering

Water deeply and regularly. Maintain evenly moist soil, especially during warm weather and active growth periods.

Pruning

Group 2 clematis: prune lightly in early spring. Remove dead or weak stems and cut remaining stems back to strong buds. Deadhead after first bloom to encourage reblooming.

Pest Control

Watch for aphids, spider mites, and slugs. Treat promptly with insecticidal soap or traps. Maintain airflow to reduce fungal issues such as wilt.

Soil Tips

Use fertile, well-draining soil enriched with compost. Mulch deeply to cool the roots and retain moisture. Avoid heavy clay or waterlogged soil.
