Hydrangea, Proven Winners® Limelight Prime® HydrangeaLimelight Prime Hydrangea is a fast growing upright deciduous shrub with rich blue green foliage noted for its dense cone shaped panicles. Its sturdy stems hold large panicles that open lime green and turn vivid shades of deep pink as it matures before eventually fading to beige as its leaves turn. The flowers are very attractive to butterflies. While it can tolerate full sun, its best blooms are in part sun and rich, moist well drained acidic soils.
