Limelight Prime®

Panicle hydrangea (H. paniculata)
Hydrangea of the Year

Care information

Limelight Prime is a panicle hydrangea, the most sun-tolerant type of hydrangea! It will thrive in full sun in colder areas (USDA zones 3-6); in warmer areas, afternoon shade is recommended.

Moist but well-drained soil is best. Panicle hydrangea flower color is not impacted by soil pH.

Average water needs. Somewhat drought tolerant once established. Mulch for best results.

Nothing special required. If desired, you may apply a granular fertilizer formulated for woody plants in late winter/early spring.

Pruning is recommended in early spring. Cut the whole plant back by about 1/3 of its height, removing any thin, spindly side branches as well. Make cuts just about 1/4 of an inch above a bud. 

Limelight Prime hydrangea makes an excellent cut flower. For its longest vase life, cut vertically up the stem about 2″. This will help it stay hydrated.

Limelight Prime hydrangea has everything you love about ‘Limelight’, but offers a more compact habit, stronger stems, an earlier bloom time, and much more colorful flowers in fall.

Stronger Stems & Brighter Blooms

This long-blooming favorite works nicely when planted as a specimen plant, in containers, and especially as hedges. It has darker, healthier-looking foliage that makes an impressive backdrop when it isn’t in bloom. Each bright lime green flower is held sturdily aloft for its entire flower show and well into the fall, when it has finished to a rich punch-pink color. If flowers are left standing for the winter, they’ll continue to bring interest to the garden.
