Little Lime Punch® Hydrangea (Hydrangea paniculata 'SMNHPH') – this shrub is a party in plant form! Bursting with colour from midsummer through fall, its blooms start lime green, then shift to pink, then red, then punchy raspberry—with all shades showing at once. It’s bold, beautiful, and completely irresistible.
This Proven Winners® variety is a panicle hydrangea, meaning it’s one of the most cold-hardy hydrangeas, thriving in zone 3 and blooming reliably on new wood each year. Its strong stems keep the blooms upright (no flopping!), and the compact size makes it perfect for small spaces or front-yard planting.
Expect a mature size of 3–5 feet tall and wide. It performs best in full sun to part shade and appreciates regular watering, especially during dry periods.

Growth Habit: Compact, rounded form with strong stems

Pro tip: Plant it where you’ll see it often—the shifting colours make this one of the most dynamic shrubs of the season!
