If you like to watch grass grow you might find this vine fascinating. It is a good plant and I have grown it in two different gardens but it is very slow to get established and I have yet to get any flowers. I have seen other people’s established vines covered with fragrant, lace-cap type flower heads up to 10” across and they are a magnificent sight but so far I have seen no flowers of my own. The new leaves that appear in the spring are a rich green color and form a dense mat on whatever it is growing. In winter, when the leaves fall, the stems remain, forming an attractive pattern on fence or wall. Climbing hydrangea is a deciduous perennial that climbs by adventitious roots so will  grows on an arbor, on a trellis, on a pergola, or up into trees as well as fences and walls.  Once the vine is established, it will grow well and can grow as much as 2’/year.  The fact that it can produce great masses of flowers in partial shade makes this a very valuable plant.

  1. I looked for more information on this hydrangea and both Dave’s Garden and hydrangea.com part of Wilkerson Mills Gardens give the info as zone 4-7. I am in zone 9a or 8b depending on the reference I look at. I would love to be able to use this plant can you help me?
