  • Award winner
  • Long blooming
  • Very hardy

Award-winning variety with distinctive lime-green blooms. Our 'Limelight' hydrangea has become a garden classic, representing the best of the genus across North America. Refreshing green blooms in mid-summer transform to pink, red, and burgundy in autumn. The blooms are well distributed and held up on very strong stems. Multiple awards, including the Missouri Botanical Garden Plant of Merit; Pennsylvania Horticultural Society Gold Medal, American Society of Cut Flower Growers Cut Flower of the Year 2007, Royal Horticultural Society Award of Garden Merit.

Adaptable to most any soil except very wet or excessively alkaline soils.


In late winter or early spring, cut back by about one-third its total height, just above a set of large buds. This ensures that the growth for the season will come vigorous buds lower on the plant and also serves to remove any remaining dried blooms. Alternatively, cut back in autumn once the plant has gone completely dormant. May be cut back harder if desired, though this tends to produce stems that are unable to achieve maximum stem strength the following season.


Specimen; mixed borders; mass plantings. Makes a good hedge or screen. Excellent for cut flowers, both fresh and dried.

Growing Tips

Panicle hydrangeas are the most sun tolerant hydrangeas and are also resistant to wilting. In cooler climates, full sun is recommended for best stem strength and flower set. We have heard reports of success with 'Limelight' in Dallas, TX, and Orlando, FL with afternoon shade and well-drained soil. Flower color is unaffected by soil chemistry. If flowers turn brown and dry instead of aging to pink or red, this indicates that the plant needs more water or that nighttime temperatures are too high for the transition to occur.
