Hydrangea arborescens 'Strong Annabelle' produces giant globes of pure white flowers which are held on extremely strong stems. It is similar in appearance to the well-liked Hydrangea 'Annabelle', but offers better wind resistance and reduced flopping for a more impressive garden display. The huge flower heads appear from midsummer through until autumn and make superb cut flowers with impressive longevity. This Sevenbark variety is ideal for cottage gardens, woodland gardens, borders or even large patio containers. Height and spread: 1.5m (5').
