Grin And Tonic Hydrangea
Hydrangea macrophylla ‘SMNHMSIGMA’Grin And Tonic Hydrangea is a compact reblooming hydrangea prized for its vivid lime-green to white blooms, strong flowering performance, and long-lasting color display. Blooming on both old and new wood, this unique mophead hydrangea produces large, rounded flower clusters that emerge in bright chartreuse-green tones before gradually aging to a soft white color. The coloration creates a fresh, modern look in the landscape and provides months of seasonal interest.
Its compact, rounded habit typically reaches 2 to 3 feet tall and wide, making it an excellent choice for smaller garden spaces, borders, and patio containers. The lush green foliage provides a dense backdrop for the vibrant blooms while helping the plant maintain a full, refined appearance throughout the growing season.
Grin And Tonic Hydrangea is especially valued for its reliable reblooming ability, producing flowers from late spring through summer and often into early fall. The blooms also age beautifully on the plant, extending ornamental interest well beyond peak flowering. The colorful flower heads work exceptionally well in fresh arrangements and can also be dried for decorative use indoors.
This hydrangea thrives in part sun with moist, well-drained soil rich in organic matter. Consistent moisture helps support the strongest flowering and healthiest foliage, especially during summer heat. Minimal pruning is needed beyond removing winter-damaged stems or spent blooms in early spring.
