Hydrangea arborescens 'Strong Annabelle' is a outstanding selection of the North American native smooth hydrangea, loved for its enormous, pure white pompom flowerheads that put on a spectacular display from midsummer through to autumn. Unlike the original Annabelle, 'Strong Annabelle' has been bred with noticeably sturdier stems that hold the massive blooms upright even in wind and rain, making it a far more reliable garden performer. As the season progresses, the flowerheads fade to a beautiful soft green and then parchment-brown, extending the ornamental interest well into winter. This is a deciduous shrub with fresh, mid-green foliage that emerges in spring, providing a lush backdrop to the spectacular blooms. Hardy, vigorous and easy to grow, it suits a wide range of garden styles from cottage to contemporary.

Growing conditions

Position: 'Strong Annabelle' thrives in a sheltered position in full sun to partial shade. It performs particularly well with morning sun and some afternoon shade in hotter climates, which helps to preserve the colour of the flowers for longer. Avoid exposed, windy sites where possible, even with its stronger stems.

Soil: Plant in moist, humus-rich, well-drained soil. Like all hydrangeas, it appreciates consistent moisture and will benefit from the incorporation of generous amounts of organic matter at planting time. It tolerates a range of soil pH and, unlike the mophead hydrangeas, its flower colour is not affected by soil acidity.

Hardiness: Fully hardy and reliably cold tolerant, making it suitable for growing throughout most of the UK and Ireland. It dies back in winter and regrows strongly from the base each spring.

Care

Watering: Keep the soil consistently moist, particularly during the first growing season while the plant is establishing and during prolonged dry spells in summer. A generous layer of mulch applied around the base will help to retain soil moisture and suppress weeds.

Feeding: Apply a balanced slow-release fertiliser in spring as new growth begins. Avoid excessive nitrogen-rich feeds, which can encourage leafy growth at the expense of flowers. A mulch of well-rotted garden compost or leaf mould each spring will also help to enrich the soil and feed the plant naturally.

Pruning: 'Strong Annabelle' flowers on the current season's new growth, which means it responds very well to a hard annual prune. Cut all stems back to just above a low pair of healthy buds in late winter or early spring, typically to around 30–50 cm above ground level. This encourages the plant to produce vigorous new shoots that will carry the largest, most impressive flowerheads. The dried flowerheads can be left on the plant over winter to provide structure and interest, and to offer some degree of frost protection to the emerging buds below.

Guide to Planting Field-Grown Root Balled Plants

Pros:

1. Established Roots: Typically stronger, established roots ensure better initial growth.
2. Immediate Impact: Larger plants provide instant structure and aesthetics.

Cons:

1. Heavy and Bulky: Can be difficult to transport and plant due to size and weight.
2. Seasonal Availability: Generally available only in the dormant season (autumn to early spring).

Preparation for Planting:

1. Unwrap Carefully: Remove any packaging material, but leave the burlap or wire basket on.
2. Keep plants moist: Plants should be kept moist until the time of planting.

Planting Process:

1. Dig a Hole: Make a hole twice the width of the root ball and the same depth.
2. Position Plant: Place the root ball in the hole, ensuring the top is level with the ground surface.
3. Do Not Remove Root Sack: Leave the burlap or wire basket around the root ball. It is bio degradable and will rot away naturally.
4. Backfill: Fill the hole with soil, firming gently around the roots to eliminate air pockets.
5. Water: Water deeply after planting to settle the soil and avoid wilting.

Possibility of Losses:

• Initial Shock: Some plants may suffer transplant shock, leading to potential losses.
• Mitigation: Proper care and consistent watering during the establishment phase can minimise this risk.

Main Causes of Failure:

1. Improper Planting Depth: Planting too deep or too shallow can stress the roots.
2. Poor Soil Conditions: Compacted or poorly drained soil can hinder root growth.
3. Insufficient Watering: Both under-watering and over-watering can lead to plant stress and failure. Strong wind can dry leafy pants.
4. Pest and Disease: Lack of protection and monitoring can result in damage from pests and diseases.

Tips for Success:

1. Stake Larger Plants: Support with stakes to prevent wind damage.
2. Mulch: Apply a layer of mulch around the base to retain moisture and regulate temperature.
3. Regular Monitoring: Check for signs of stress, pests, and disease, and address them promptly.

By following these guidelines and providing consistent aftercare, you can successfully plant and establish field-grown root balled plants in your garden.
