Clematis ‘Manju’

Clematis ‘Manju’ is a truly distinctive Japanese cultivar, celebrated for its exquisite, fully double, pompom-like flowers that unfurl with delicate green tips maturing to creamy-white. We find its generous and extended flowering season makes it a sensational choice for training up walls, fences, and pergolas, or as a stunning focal point in a large container.

Product information

Clematis ‘Manju’ is a real showstopper, a unique Japanese hybrid that we’ve been delighted to grow here at Tandee Nursery. Its most captivating feature is undoubtedly its abundant, multi-layered flowers, which resemble miniature cactus dahlias or elegant pompoms. They begin as intriguing pale green buds, gradually unfurling to reveal exquisite creamy-white petals with those charming green tips that give them such a fresh, sophisticated look. It’s a vigorous and healthy climber that truly stands out, offering a continuous display of these fascinating blooms over many months.

This delightful clematis is surprisingly unfussy, thriving in a position from full sun to partial shade, though like most clematis, it prefers its ‘feet in the shade’ – meaning cooler, moist soil around its roots. We always recommend planting it a little deeper than it was in its pot, about 7.5cm (3 inches) below soil level, to encourage a strong, multi-stemmed plant. It performs best in fertile, well-drained soil, enriched with plenty of organic matter. Once established, it’s quite hardy, enduring typical UK winters with ease, generally down to around -15°C.

As a Pruning Group 3 clematis, ‘Manju’ flowers on new growth, making its care wonderfully straightforward. We advise a hard prune in late winter or early spring, cutting all stems back to a pair of healthy buds about 20-30cm (8-12 inches) above ground level. This encourages a profusion of new shoots and a magnificent display of flowers from late spring right through to autumn. Its moderate stature makes it ideal for combining with climbing roses, scrambling through shrubs, or gracing an obelisk in a mixed border. For container growing, ensure a large pot with good drainage and a sturdy support.

Pruning
Prune hard in late winter or early spring (Pruning Group 3), cutting back to about 20-30cm (8-12 inches) above ground level.
Seasonal Spring
New shoots emerge, often tinged with purple. Pale green flower buds begin to form, gradually opening into their distinctive creamy-green blooms. This is the ideal time for its annual hard prune and to apply a balanced feed and mulch.
Seasonal Summer
The plant is a profusion of its unique, double creamy-white flowers with green tips, blooming continuously. Ensure consistent watering, especially during dry spells, and feed regularly for sustained flowering.
Seasonal Autumn
Flowering continues generously, often right up until the first hard frosts. The deciduous foliage may develop purple tints before falling, preparing the plant for winter dormancy. Consider mulching around the base.
Seasonal Winter
The plant is dormant, with deciduous stems. It is hardy and will withstand typical UK winter temperatures. Protect the crown with a mulch in colder areas. Prepare for pruning in late winter.
