Type

Family
Hydrangeaceae

Hydrangea paniculata ‘Moonrock’ is a compact and very luminous shrub hydrangea, appreciated for the exceptional density of its flowers and its solid, well-balanced habit. This variety is distinguished by its very thick, conical panicles, composed of a high proportion of sterile flowers, which gives them a massive and almost sculptural appearance. The inflorescences open pure creamy white and retain their light hue for a long time before sometimes taking on a slight pinkish tinge at the end of the season. Its overall habit is compact, dense, and slightly taller than wide, making it an excellent choice for structured beds, low flowering hedges, and medium-sized specimen plantings. Like all Hydrangea paniculata, ‘Moonrock’ blooms on new wood, ensuring reliable and abundant flowering every summer. The medium green deciduous foliage perfectly showcases the spectacular blooms and maintains a beautiful appearance until autumn. Robust, very decorative, and easy to integrate, it makes an excellent choice for northern and residential gardens.
