Pink anemone clematis is a vigorous deciduous climber that grows 25 to 30 feet and produces small, pale pink, 2-inch flowers in late spring to early summer. As a member of pruning group 1, it should be pruned immediately after flowering by removing some of the older stems. Pink anemone clematis is hardy to USDA Zones 7-9 and is not reliable in very cold areas. It grows well along a wall or fence or through large trees.
