Hydrangea petiolaris (Climbing hydrangea)
H. anomala subsp. petiolaris is a deciduous shrub usually grown as a self-clinging climber, but also suitable for cultivation as a stand alone shrub. It has fresh-green, serrated, ovate leaves and in early summer, bears large, pretty, white lace-cap flowers. It is a useful climber for North-facing walls and fences.
Plant in humus-rich, moist, free-draining soil in sun or shade. If grown as a climber, provide support until established. Mulch and feed in spring. Will reach a height of 15m and a spread of 5m after 5-10 years.
