LimelightHydrangea paniculata 'Limelight' is a relatively new cultivar of Hydrangea paniculata, the panicle hydrangea. Here, the large, dense, upright, cone shaped flower clusters (to 8" across) open creamy white, then mature to chartreuse lime and eventually acquire rose tones before finally fading to beige. As the flower show fades in the fall, the leaves turn attractive shades of red, making a stunning finish. Panicles may be cut for fresh arrangements or
