Phlox carolina ssp. carolina ‘Kim’ is a fantastic selection that was discovered by Jan Midgley in Alabama. It performs much better than any other cultivar of Carolina phlox in our trial. What sets ‘Kim’ apart from other members of the species is its lush and vigorous habit (2’ tall) that remains sturdy and disease-free all season long. The leaves are also a lighter shade of green, almost lime-colored, which can prolong its horticultural interest in the garden. However, the most impressive feature of ‘Kim’ is its show-stopping light pink flowers which blanket the plant from late May through early June. Mt. Cuba Center
