CLEMATIS 'Royalty'

Image of Clematis 'Royalty'

Family

Ranunculaceae

Botanical Name

CLEMATIS 'Royalty'

Plant Common Name

Clematis, Early Large-flowered Clematis, Royalty Clematis

General Description

The large semi-double and single flowers of ‘Royalty' are violet-blue with a flourish of buttery stamens in the center of each. This mid-season bloomer was bred by John Treasure of The United Kingdom. Early on it produces semi-double flowers and towards the end its flowers are smaller and single.

Hybrid clematis is a hardy deciduous woody vine that climbs by twining stems. The vines are lined with green compound leaves that appear in spring. The large flowers appear from late spring to summer and are followed by fluffy clusters of silvery seeds.

Clematis grows best in sites with full sun and fertile, well-drained soil. It grows and flowers best if its roots remain cool under a vegetative layer or thick mulch. If left unpruned, plants will sporadically flower again in fall. As with most clematis, this selection adds a vertical element to the garden and looks best when trained on a fence, trellis or pergola.

This is a Group 2 clematis, which means its flower buds develop on the previous year's growth, so pruning should be done after it blooms.
