Care tips
This clematis prefers full sun to partial shade, ensuring that its roots remain cool and shaded. It requires well-drained, fertile, and slightly alkaline soil. Keep the substrate consistently moist, especially during dry periods, and avoid waterlogging. A common mistake is improper pruning: a hard prune in late winter or early spring (Group 3) is recommended to encourage abundant flowering.
