Clematis Texensis Princess Diana Climber

Clematis Texensis Princess Diana (Synonym: Clematis Texensis The Princess of Wales) is a superb deciduous climber that brings bold summer colour to the garden. With its rich heritage and Award of Garden Merit (AGM) status, this popular cultivar is part of the Clematis Texensis group – known for its distinctive tulip-like flowers and compact growth habit. This variety is a must-have for enthusiasts looking for a striking flowering climber that performs well on current year's growth.

Part of the Clematis Texensis family, Princess Diana produces an abundance of elegant, tulip-shaped flowers in a vivid pinkish red shade. Each bloom, up to 6 cm long, is adorned with creamy maroon stamens that create a dramatic contrast and draw in pollinators. Flowering from mid summer through to early autumn, it provides a welcome burst of colour when many other plants are past their peak. The foliage is a fresh, medium green with a graceful, twining habit that lends itself beautifully to climbing supports or weaving through shrubs.

The Clematis Texensis group is native to the southern United States and is admired for its late blooming cycle, unlike the earlier-flowering Clematis Armandii or the showy double blooms of Clematis Florida types such as Alba Plena. Princess Diana has been bred to offer exceptional garden performance in UK conditions, flowering on the current season’s growth – making it both reliable and easy to prune.
