Clematis are divided into three groups that reflect bloom and pruning times. Group I includes early (spring) bloomers, such as this Armand clematis. These are extremely vigorous and bloom on old wood (the prior year’s shoots). Flowers are usually small and generally white. This group requires little pruning: Remove dead wood and then shape where necessary right after flowering.
