Hydrangea ''Annabelle' produces large round balls of white flowers in late summer/autumn. Very impressive when planted as a hedge. However, they need to be cut hard back in spring to keep the height under control, as the flower heads get very heavy, and if they are the end of a long branch, will droop so much they nearly hit the ground.
Every garden should have some.
These are newly potted at 1.10.21 and will be ready in March.
