Clematis koreana 'Dark Secret' is a spring-flowering clematis featuring pendulous dark purple flowers - similar to 'Candleglow' but darker and more mysterious.
Creamy edged margins on the tepals offset the green pinnate leaves.
Attractive seed heads remain on the plant after the flowers have finished.
Clematis koreana 'Dark Secret' was raised by Vince and Sylvia Denny of England. It was named and introduced in 1999 by John Richards of John Richards Nurseries Ltd, Colwall, England.
