3 Litre Hydrangea Arborescens Incrediball 'Strong Annabelle' : A relatively newcomer to the Hydrangea family whilst closely related to the more well-known Hydrangea Annabelle, what makes this plant different is the sturdy upright stems that hold the huge flower heads in place as it matures the flower heads are upright and pronounced and rarely flop over even when the flowers reach full maturity and size which can be in excess of 30cm. These plants are already established and will give a dazzling flower display this summer.
For want of a better choice of words visually these plants are past their best for 2020 they are well rooted into 3 litre pots, fully hardy and flower annually on new growth so a great plant to get in the ground in autumn or early winter in preparation for summer 2021. The pictures were taken late October 2020 so if purchased before March just how they will look.
