Hydrangea anomala petiolaris
The famous climbing hydrangea. This is the best of the anomala species. The beautiful climber takes a few years to really get going but then grows and climbs its way around and up. It can be enjoyed as a ground cover with its white lacecap type flowers, or let it climb up old stumps or wood walls and it will put on a spectacular display. This plant is also fantastic when allowed to grow up a tree, and does little if any harm provided that it is not allowed to cover the tree’s top growth and foliage. Very hardy but needs sun to be at its best.
