Quick Guide

  • Large, snowball-like white blooms

  • Flowers from mid-summer to autumn

  • Ideal for borders and hedging

  • Thrives in sun or partial shade

  • Awarded RHS Garden Merit

Hydrangea arborescens ‘Annabelle’ is renowned for its spectacular, spherical clusters of creamy-white flowers, each up to 25–30 cm across, that bloom profusely from mid-summer into autumn. As the season progresses, these blooms transition to a subtle lime-green before fading to parchment tones, providing extended visual interest.

This deciduous shrub features broad, ovate green leaves and a rounded, bushy habit, reaching up to 2.5 metres in both height and spread. ‘Annabelle’ is particularly striking when planted en masse in borders, as a flowering hedge, or as a standalone specimen. Its robust nature and adaptability make it a favourite among gardeners seeking reliable, long-lasting summer colour.

Awarded the Royal Horticultural Society’s Award of Garden Merit, ‘Annabelle’ is a testament to exceptional garden performance and resilience.

Plant Care Guide

Plant ‘Annabelle’ in moist but well-drained, fertile soil enriched with organic matter. It thrives in full sun to partial shade; however, in hotter regions, partial shade is preferable to protect the blooms and prevent wilting. Regular watering is essential, especially during dry spells, as hydrangeas are sensitive to drought.

In late winter or early spring, prune back the previous year’s growth to a strong pair of buds to encourage vigorous new shoots and larger flower heads. Young plants may require staking or support to prevent the heavy blooms from causing stems to arch or break.

For London postcodes outside a 5-mile radius of our Kentish Town garden centre, we may occasionally use a third-party courier for delivery. In these cases, we try our best to still deliver the items in the requested delivery time slot but please be aware that occasionally this may not always be possible and is out of our control.

Delivery Discrepancies

Please check your order as soon as it arrives. If there is any discrepancy — such as a missing, incorrect, or damaged item — please contact us within 48 hours of delivery so we can put things right. After this time, we will assume the order was received complete and in good condition. We are unable to take responsibility for damage that has occurred after this period.

Click & Collect

We encourage you to collect from our garden centre in Kentish Town — it saves on delivery costs and gives you the chance to see our full range of plants and products in person.

Returns Policy

If you need to return an item, please contact us within 14 days of receipt to arrange a return or exchange. Products must be in their original condition and packaging. Plants may be non-refundable unless they arrive damaged or defective.

Items bought in-store or collected can be returned directly at the garden centre. If you would like us to collect a return and it is in good condition (e.g. you have changed your mind), it must be in its original condition, and the same delivery cost will apply for the return.

Plants marked as reduced for end-of-season clearance are non-refundable, as they are sold specifically to clear stock. This does not apply to special offers or multibuy promotions, which are eligible for returns as per our standard terms.
