It can take newly transplanted climbing hydrangea vines a year or two to become established, so don't give up on them too soon. Seeds germinate readily but take several years to put on substantial growth. The vines grow quickly once established but it may be three to five years before you see flowers.What does climbing hydrangea mean?
Climbing hydrangea is one of the few hardy flowering vines that tolerate shade . In hot climates, choose a location where the plant will get some partial shade. In the cooler regions of the South, the vine will usually do well in more sunny areas, if adequately watered. Climbing hydrangeas that do get more sun tend to bloom better.
