Hydrangea Petiolaris A stunning climbing shrub!A fantastic plant for a shady wall, Hydrangea Petiolaris (the climbing hydrangea) forms a dense cover punctuated by lacy white flower heads in early summer. It takes a while to establish, but the two or three-year wait is worth it. When it does take off, it will rapidly spread & cover otherwise difficult-to-grow places. An elegant climbing Hydrangea that's perfect for those cold, north facing walls that rarely see the sun. As autumn approaches, its heart-shaped leaves turn a buttery shade of yellow that will brighten even the darkest corner. Although a little slow to get going, once established this superb RHS AGM variety will quickly scale walls & fences with its clinging aerial roots.
