Hydrangea quercifolia (oak-leaved hydrangea) is a member of the Hydrangeaceae family. This deciduous shrub exhibits a bushy growth habit and is characterized by its deciduous foliage. It has a hardiness rating of hardy – cold winter (-15 to -10ºc) and is hardy through most of the UK even in severe winters. May not withstand open or exposed sites or central / northerly locations. Many evergreens suffer foliage damage and plants in pots will be at increased risk.
When fully mature, Hydrangea quercifolia can reach an ultimate height of 1–1.5 metres and a spread of 1.5–2.5 metres. For optimal growth, it prefers a north–facing, west–facing, east–facing, or south–facing aspect and an exposed or sheltered position. It thrives best in clay, loam, or sand soil types and should be placed in full sun or partial shade.
