Invincibelle Limetta Hydrangea (PW)

Invincibelle Limetta® Hydrangea (Hydrangea arborescens 'NCHA8') – fresh, bright, and impossibly easy to love! This Proven Winners® hydrangea delivers lime green blooms that soften to creamy white, then back to jade as the season ends—giving you months of colour and elegance from summer into fall.

Unlike some hydrangeas, Limetta blooms on new wood, meaning it flowers reliably every year, even after harsh winters. It’s also cold hardy to zone 3, making it an excellent choice for Prairie gardens.

This compact, rounded shrub reaches about 3–4 feet tall and wide, thriving in full sun to part shade. It prefers consistent moisture, especially in hot spells, and benefits from well-drained soil. Deadheading isn’t necessary but can encourage a tidier look.

Zone: 3 (very cold hardy and reliable bloomer)
Sun: Full sun to part shade
Water: Regular moisture; appreciates watering during dry periods
Growth Habit: Compact, mounded form with strong stems
Uses: Foundation plantings, borders, mass plantings, cut flowers

Pro tip: Plant in groups for a soft, glowing hedge—or mix with dark-leaved perennials to make those lime blooms pop!
