Hydrangea anomala subsp. petiolaris

A Climbing Hydrangea, anomala subsp. petiolaris is a vigorous deciduous vine from Japan and Korea whose heart-shaped foliage and large white clusters of June flowers make it an attractive covering for a wall, fence, or large tree. 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. Plants are slow to start, but the lateral branches extend as much as 3' and the vines will eventually grow to 40' or more. Winner of the RHS Award of Garden Merit.

Climbing Hydrangea plants have lateral branches that grow out as much as 3′ from the supporting structure, giving a rich, deep texture that is quite unlike that of other vines. The dried flower heads and reddish brown, peeling bark are attractive in winter. Produces aerial roots that cling to its support. Not well adapted to the dry heat of desert regions. Blooms on old wood.

Hydrangea is a valuable genus of some 100 species of shrubs and vines grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall—a quiet time for most woody plants—and are worth having for that reason alone. For more information on Hydrangea care, click on Growing Guide.

We want our customers to receive strong, healthy plants that are ready to thrive in their gardens and homes. Here's what we'd like you to know about our shipping practices.

Delivery Timing

We aim to deliver your plants at as close to the proper time for planting in your area as possible. To do so, we consider the USDA Hardiness Zone to which we're shipping, current and forecasted weather at the destination and along the shipping route, and whether your plants are ready for transplant.

In spring, we ship first to the warmest regions and move north as planting conditions improve. For fall deliveries, we begin with the coolest regions and work south. We frequently adjust shipping schedules when extreme weather could put plants at risk while in transit or soon after arrival.

Because different plants reach readiness at different rates and are weather-sensitive in varying degree, a single order may be delivered via multiple shipments. Plants sold as part of a collection, or that are otherwise meant to arrive together, will be shipped together. Please contact our customer service team with two weeks' advance notice if you anticipate being away at the expected time of delivery. 

Tracking information for each package is delivered via email. 

Plant & Container Sizes

We deliver plants in various sizes and stages of growth, and the product detail pages of our website indicate the form and/or pot size in which the plant will be delivered. Pot sizes range from 1 pint to 1 gallon and larger. Many perennials, roses, shrubs and vines are delivered bareroot - that is, not in a container at all. Bulbs and tubers are generally delivered bareroot and fully dormant. We choose container sizes and delivery methods based on how each plant grows best, how we can minimize transplant shock, and how to minimize unnecessary bulk/weight in shipment. 

Caring for Your Plants Upon Arrival

It is important to acclimate greenhouse-grown plants to life outdoors. All plant shipments include simple instructions for handling your plants upon arrival. Further how-to information, including planting instructions, is available on each plant's product page.

Growing H. anomala petiolaris

Climbing Hydrangea (H. anomala petiolaris) will grow and flower even in a northern exposure. This large, heavy vine has lateral branches that will grow out as much as 3′ from the supporting structure. It is superb for growing up the trunk of large shade trees, walls, or along a stonewall. The reddish brown, peeling bark is attractive in winter. Although growth is slow the first couple of years after planting, this species is vigorous once established. Blooming usually begins in 3–5 years.

Light/Watering: Most varieties thrive in full sun in the North, but in the South require afternoon shade. Moist soils that do not dry out are best; do not plant in hot, dry, exposed sites. Mulch to conserve moisture and buffer soil temperatures.

Fertilizer/Soil and pH: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15). Soils should be moist but well drained, and rich in organic matter.

Pests/Diseases: None serious. Occasionally powdery mildew will infect the foliage, especially in humid areas with poor air circulation. Treat with an appropriate fungicide if the problem is serious, and be sure to rake up and destroy all fallen foliage in the autumn.

Pruning: Remove any dead wood in early spring. Prune as needed after flowering. Blooms on old wood.

Transplanting: Young plants may be transplanted when dormant in early spring. Prune top growth after transplanting to reduce water loss.

End of Season Care: Rake up and destroy any fallen foliage that was infected by powdery mildew or other fungi.

Calendar of Care

Early Spring: Prune as indicated above. Feed plants with a fertilizer high in phosphorus (such as 15-30-15) to encourage blooms. Complete any transplanting before leaves unfurl.

Mid-Spring: Mulch plants after soil has warmed to conserve moisture and buffer soil temperatures. Watch for powdery mildew and treat as needed.

Fall: Remove and destroy any fallen foliage that was infected by powdery mildew.
