Clematis Hayate

Clematis 'Hayate' is a beautiful Japanese variety from 2008 that captivates with the size of its velvety violet flowers reaching 20cm (8in) in diameter. The petals, which are actually sepals, do not overlap like in other clematis varieties but fold backwards at their base, forming diamond-shaped stars. Their large protruding hearts are filled with long white-cream stamens, giving them the appearance of tiny double chrysanthemums. This vigorous variety flowers in spring and autumn.

The 'Hayate' cultivar is a deciduous climber belonging to the Ranunculaceae family. Like most of its cousins, it prefers light, deep, moist and fertile soil that is preferably neutral. It enjoys a sunny or partially shaded exposure, with its base always in the shade. It tolerates cold and is not afraid of frost. However, it does not like stagnant moisture, so the substrate must be well-draining and watering should be moderate (if necessary, during the first year). It can be grown in a container if the pot is large enough (minimum 60cm (24in) in diameter).

'Hayate' can reach up to 3m (10ft) in height and 1.5m (5ft) in width. It is a Group 2 clematis, which means it has large flowers and blooms in spring, with a second flowering in autumn. The woody stems from the previous year bear the double flowers of spring from May to June. These flowers normally have 6 to 8 petals, reaching 15 to 20cm (6 to 8in) in diameter. The late summer flowering (borne on the current year's branches) takes place in September. The flowers, then single stars, display the same colours that give them a piquant charm. They reveal a heart of bristly stamens. Afterwards, fruits appear, which decorate the foliage and last until winter. The deciduous and bright green leaves are composed of 3 to 5 leaflets. They are borne on voluble petioles called tendrils that twine around their support.

It will look wonderful in a container with a trellis to support it. It will flower for a long time, even in partial shade. Plant some spring bulbs or a geranium at its base and enjoy the spectacle with minimal maintenance. If you have a larger space, this non-invasive clematis can weave its way up a bamboo teepee or column and bring verticality to a vibrant flower bed. Large-flowered repeat-blooming clematis are also the best companions for roses. Consider combining 'Hayate' with white and light pink blooms like those of 'Felicité et Perpétue' climbing rose or the silver or golden foliage of spirea, ceanothus, and Japanese spindle tree. The combination with a shrub with golden foliage like Choisya ternata 'Sundance' will enhance the velvety colour of its flowers.
