Hydrangea anomala ssp. petiolaris
Blooming Time
Exposure
Although slow to start, after a season or two to become established, climbing hydramgea gains considerable steam and becomes rather assertive, often putting on a foot or more of growth in a single season. With root-like holdfasts and semi-twining habit, it will cling to either trees, bricks, or fencing. Climbing hydrangea serves well for screening but can also be used as an accent or specimen plant, or when unsupported, as a ground cover. Its decidous rounded foliage is lush dark green, the perfect backdrop to its gigantic 6 to 10 inch wide white flower clusters which burst into bloom during the months of June and July.

Care
Watering:
Climbing Hydrangea is moderately drought tolerant but benefits from occasional watering, to maintain soil in a moist but not wet condition, during the summer months.
Fertilizing:
Climbing Hydrangea is a moderate feeder, benefiting from a couple of annual applications of slow release fertilizer. A spring application of a 3-1-2 ratio (such as a 15-5-10) can be applied at a rate of about 10 pounds per 1000 square feet, and during early fall, an application of a 2-1-2 ratio (such as a 10-5-10) can be applied to encourage root development and cold hardiness.
Pruning:
Climbing Hydrangea sets its flower buds in summer, and any pruning should be conducted in April, immediately after winter.
