Hydrangea petiolaris originally introduced in the late 1800s from Japan and Korea has become a favourite where a self supporting climber is required. Easy to grow in even the toughest of locations it makes a substantial framework covered in attractive green leaves for much of the year. Spring is greeted with masses of corymbs made up if dainty greenish white flowers. It is slow to start and may require some support until it begins to produce aerial roots, however after a year or so it will begin to grow quite vigorously. The size criteria given here are average as the plant is often used in shady or other difficult locations. In ideal locations 25mtrs is not unheard of! It can be grown in the garden or in a pot or container. In containers use a good quality John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade, become too packed and choke the roots. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 12-14 month applied in late winter as buds swell. One application gives all the nutrients the plant requires for the whole year. John Innes is a soils based compost. Prune immediately after flowering and remember, if you leave it too long before pruning, it is not just a case of just cutting off the branches, you will also need to tug them off whatever they have clung too! Excellent in industrial and seaside areas.
