A beautiful upright growing phlox for average to moist soils in full sun or part shade. This phlox has late spring to early summer flowers of bright rose pink on stems up to 3 feet tall. Cut back after flowering for repeat bloom. Leaves are glossy, dark green, long and narrow, and plants form a gradually enlarging clump.
