What Group Is My Clematis?

Once you know the group, you can prune accordingly

Clematis varieties are classified into three groups according to blooming time and characteristics: Group 1 (spring bloomers), Group 2 (repeat bloomers), and Group 3 (summer or fall bloomers). Each group has its own pruning protocol; see Pruning Clematis for detailed information on timing and techniques.
