Climbing hydrangea and false climbing hydrangea

A few folks wanted to know more about climbing hydrangea (Hydrangea anomala petiolaris), after they saw ‘Harry’ in his glorious ‘attire’.   Climbing hydrangea is one of the few flowering vines that can handle shadier spots (not cave conditions!)  It can grow 30’ or more where it’s happy.  Stunning, white lace-cap flowers appear in June, creating a breathtaking display.  Its aerial roots will attach to whatever it’s allowed to ascend.  Do not grow it on the side of your house or any other structure that may be damaged by is clinging roots.  If you want climbing hydrangea to sweep up the side of a house, give it a trellis to climb on, that is secured at least 6” from the building.  Or you can just let it scramble over a stonewall or retaining wall. 

As you saw, I have mine climbing up a huge oak tree. The only maintenance I do is in the spring.  I cut some of the stems with my Corona hand pruner at their base to allow more airflow to the tree’s bark.  I don’t want insect or disease problems caused by too much moisture from a lack of sunlight. Climbing Hydrangea is one of a few in the hydrangea family that has a lovely fall foliage.  The leaves turn a eye-popping, golden yellow before dropping. Then peeling bark carries the show through winter. This is not a plant to buy if you’re not a patient person. It can take up to seven years for a plant to bloom. When buying climbing hydrangea, buy the biggest, most mature one you can for a quicker return on your investment.   

Another option would be to buy false climbing hydrangea, also called Japanese hydrangea.  The botanical name is Schizophragma.  This vine is similar to climbing hydrangea but the lacecap flowers can be pink or white, plus they will usually go into bloom by their fourth year of maturity.  The leaves of false climbing hydrangea are silvery appearance and can have a bluish tint.  

Climbing hydrangea is hardy to zone 4; false climbing hydrangea to zone 5.
