This is a vigorous climbing deciduous vine (anomala subsp. petiolaris) once established and produces lovely white lacecap blooms June-July. The flowers have a light, pleasing scent reminiscent of green apple and cucumber. The plant will start out slow and have a more bushy habit but will become quite vigorous with time.

Growth Habit

The vines attach with aerial rootlets, and require a sturdy support, such as a brick chimney, wooden fence or pergola, stone wall, or large tree (won't cling to siding well). At maturity, this plant grows 50-80' tall and 5-6' wide.

Care

Prefers fertile, well-drained soil and will tolerate full sun in cooler climates as long as it gets consistent moisture. It does not do well in hot, humid locations.  Apply a layer of mulch after planting, and provide water regularly the first year or two, to establish. They are heavy feeders, so provide an all-purpose fertilizer after flowering. May be pruned lightly every year to control size if desired; this should be done after flowering. Do not cut this back to the ground. It thrives in sun or shade (afternoon shade is required in the Deep South and in western Zones 9 and 10) and in moist but well-drained soil. 

Toxicity

Climbing Hydrangea is toxic, containing cyanogenic glycosides harmful to dogs. In general, hydrangeas are definitely not a favorite for deer. However, we would never consider hydrangeas deer resistant or deer proof.
