Annabelle Hydrangea
Hydrangea arborescens 'Annabelle'Hydrangea ‘Annabelle’ (Hydrangea arborescens ‘Annabelle’) is a much-loved deciduous shrub prized for its large, showy blooms and its ability to enhance a variety of garden designs. This cultivar produces enormous globe-shaped flower clusters, measuring up to 10 inches in diameter, which captivate with their beauty. The flowers emerge as pale green buds, gradually transforming into pure white blossoms that brighten the landscape from mid-summer through early fall. As the blooms mature, they fade back to green, extending their visual appeal into late autumn. Furthermore, ‘Annabelle’ is recognized for its ability to rebloom after pruning, ensuring a long-lasting display of flowers throughout the season.
Reaching a height and width of 3–5 feet, this shrub forms a pleasingly rounded shape, making it ideal for borders, hedges, or foundation plantings. It thrives in USDA zones 3–9, performing well in a variety of climates and conditions. While it tolerates diverse soil types, this hydrangea prefers moist, well-drained, organically rich soil for optimal growth. It adapts to full sun and partial shade, though it benefits from afternoon shade in hotter climates. Because of its versatility, it fits seamlessly into cottage gardens, woodland settings, and urban landscapes alike.
To ensure success with Hydrangea ‘Annabelle,’ consistent care is essential. Deep and regular watering during dry periods supports healthy foliage and vibrant blooms. Adding mulch around the base not only helps retain soil moisture but also suppresses weeds and regulates root temperature. For lush and abundant growth, apply a balanced, slow-release fertilizer in early spring. Prune the plant in late winter or early spring to remove weak stems, encourage robust growth, and shape the shrub. Deadheading spent flowers can extend the blooming period, further enhancing its beauty.
