Climbing hydrangea is a self-clinging climber, so no support is needed, it will stick and slimb up most surfaces with ease. Its slow to establish, but when established will grow quickly and growth of 5' a year is the normal.
We have some of this planed in the NWRC and also we planted some in the Artist Garden project for City of Culture. A winner for a north facing or cold wall. see here for more, remember your Mycorrhizl fungii when planting!
