Clematis 'Royalty' produces very showy, rich velvety purple flowers that are semi-double during May and June giving a pretty, ruffled, layered effect and then open single during August. This non-evergreen climber can be grown against a trellis, garden fence, wall, arches, pillars, pergolas, clambering over tree stumps and through large shrubs or planted in a container trained up bamboo canes or an obelisk.
Clematis 'Royalty' was raised by John Treasure, Treasures of Tenbury, England.
