A favorite of many gardeners - and deservedly so - Hydrangea arborescens 'Annabelle' (Smooth Hydrangea) is an outstanding flowering shrub. In early summer, this small, bushy deciduous shrub produces huge, rounded flower clusters, up to 12 in. across (30 cm), that brighten shady areas and bring life to the garden. Blooming for up to two months, the blossoms open lime-green, mature to brilliant white, then back to pale green in late summer before switching to a tan shade in the fall. Prized for its excellent resistance to insects and diseases, Annabelle is a good choice for the mixed border. The flowers make great cut flowers, fresh or dried.

• Performs best in full sun or dappled shade (the hotter the climate, the more shade is needed). Best grown in average, evenly moist, but well-drained soils. Full sun is tolerated if constant moisture is provided.
• Perfect for shrub or mixed borders, wonderful planted as a flowering hedge, excellent backdrop for your favorite perennials.
