Hydrangea Arborescens Lime Rickey - Proven Winners Hydrangea arborescens Lime Rickey is as lime as the name states! This rounded, deciduous shrub boasts broad, dark green leaves and domed lime green flower heads. These can grow up to 15cm (6") across in size and provide excellent coverage. The flower heads make a fantastic contrast to the foliage backdrop, and the blooms gradually emerge white later in the year. Lime Rickey is perfect for cut flowers when in full bloom and can be used in both fresh and dried indoor arrangements. This impactful shrub is hardy enough but will thrive better when sheltered from cold and dry winds. Height and spread: 1.2m (4').
