This improved version of the classic ‘Annabelle’ hydrangea features blooms that can reach up to 12 inches in diameter, creating a dramatic visual impact in any garden. The flowers begin as lime-green buds, transitioning to pristine white in mid-summer, and age to a soft jade green as the season progresses. Unlike ‘Annabelle,’ the strong stems of ‘Incrediball’ prevent the heavy blooms from flopping, ensuring a tidy and upright appearance throughout the growing season.
This shrub typically grows 4–5 feet tall and wide, forming a rounded, bushy habit that works well in borders, hedges, or as a standalone specimen. Hardy in USDA zones 3–8, ‘Incrediball’ thrives in full sun to partial shade and prefers moist, well-drained, organically rich soil. While tolerant of various soil types, it performs best in consistently moist conditions. Its adaptability makes it suitable for cottage gardens, woodland settings, or urban landscapes. Additionally, its blooms attract butterflies, adding ecological value to its ornamental appeal.
Hydrangea ‘Incrediball’ is easy to care for and low-maintenance, making it a favorite among gardeners. Deep and regular watering during dry periods ensures healthy foliage and vibrant blooms. Mulching around the base helps retain soil moisture, suppress weeds, and regulate root temperature. Fertilizing in early spring with a balanced, slow-release fertilizer promotes vigorous growth and abundant flowers. Pruning can be done in late winter or early spring to shape the plant and encourage reblooming. Cutting back the plant by one-third of its height strengthens the stems and supports larger blooms.
