Large Hydrangea Arborescens Incrediball also known as the Strong Annabelle in Large 12 or Extra Large 20 Litre Pots: This is a relatively new introduction 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.

The last picture was taken in December and is our new 2024 20 litre plants, well branched strong plants.

Planting Position: Hydrangea Incrediball are happy in full sun through to partial shade in a position where they can take centre stage, may be advisable to plant away from windy sites to protect the flowers whilst in bloom.

Soil: Any, but prefers well drained moderately fertile Humus rich.

Suitable for container planting: Yes but will do better planted in a sunny border, away from exposed windy sites

Eventual Height and spread: Up to 3 metres tall with a 2 metre spread.

Growth speed: Moderate.

Growth Habit: Upright and bushy Flowers: Produces huge white blooms which can be as big as 30cm in diameter held upright by strong sturdy stems.

Flowering period: July through to September.

Evergreen: No

Winter Hardy: Yes

Pruning: Remove faded flower heads in spring after the frosts have passed, cut back the stems to approximately 2cm above a strong pair of buds and remove any misplaced or diseased branches.

In hot weather ensure the plant gets a thorough soaking to prevent the roots drying out. Mulch plants with well rotted manure or compost in early spring.

When should I prune back my Hydrangea:

We suggest waiting until Febrary/March when the frosts have gone.    The dead flower heads will protect the plant over the winter months.    When the frosts have finished cut it back by approximately a quarter and remove any weak or frost damaged shoots to the healthy wood.
