About Rough-leaved hydrangea
Hydrangea aspera, commonly known as rough-leaf hydrangea, is a medium to large deciduous shrub prized for its large, velvety leaves and showy, flat-topped flower clusters, comprising central fertile florets and marginal sterile ones. Its distinctively textured leaves provide unique tactile and visual appeal in the garden. It is ideal for the back of mixed borders, woodland gardens, or as a specimen plant in semi-shady areas.

Care tips
Prefers partial shade or filtered light, avoiding intense direct afternoon sun which can scorch its leaves. Keep the substrate consistently moist, especially during dry and hot periods, but ensure good drainage to prevent waterlogging. Thrives in organic-rich, slightly acidic to neutral soils. A common mistake is planting it in full sun or in soils that dry out quickly, leading to water stress and leaf burn.
