Combining large green leaves with massive rounded flower heads, ‘Strong Annabelle’ is an absolute stunner in that shadier spot on a patio or in a courtyard. Each flower head is made up of multiple small flowers - we call this an ‘inflorescence’ in horti jargon - which are a calming classical white with just a hint of green. Holding the flowers in place are strong sturdy stems that have been specially bred to take the weight of the blossom, but also to resist windier conditions and the threat of snapping. When the shrub loses its leaves over Winter, the stems maintain a handsome architectural shape.
You can deadhead your Hydrangea throughout summer to encourage flowering, but it’s a good idea to leave it be as autumn approaches. This allows as much energy to go back into the plant as possible. You can then cut the remaining dead flower heads off in late Spring, once any fear of frost has passed. Cut them back to just above a pair of new healthy buds.
At the same time as removing last year’s flowers, you can keep your plant healthy by pruning out any dead, diseased or dying stems as well any crossing or inward growing material. Give your shrub a nice open shape so that plenty of air and light can get in between the stems, leaves and flowers. Once your plant has matured, you can take your pruning a step further and cut back one third of the stems to the base. This will ensure it keeps a nice compact shape and create a branching bushier shrub. Always mulch your plant after pruning, this will help it recover faster.
Be aware that the sap may irritate your skin, so wear gloves when handling
Did you know?
‘Hydra’ means ‘water’ in Latin, referring to this shrub’s love of moisture, and ‘arborescens’ means tree-like, referring to its shape. Botanical names tell you a lot about a plant before you’ve even seen it - if you have a love and understanding of Latin that is! No judgement from us if you don’t.
