The Latin name is Hydrangea Petiolaris; it's a fabulous showy, late spring and early summer flowering climber.
The images do not do it justice.
The climbing Hydrangea is very easy to grow, too easy, a touch vigorous but not seriously so. It can be slow to get going, but once established it is fairly fast growing. It is important when first planted and establishing the shrub not to let it dry out.
A great advantage when growing this Hydrangea is that it needs no attention. It is self clinging with aerial roots, the flowers are a creamy white and it is deciduous.
It will tolerate semi shade and suitable for a north facing wall, which makes this climbing Hydrangea a useful climbing plant for shadier areas. Although the climbing Hydrangea is most suited to growing on moist soil, it is very tough and will grow more or less anywhere.
It is vigorous, growing up to 25m ( 80ft) which means it will cover a big area, the whole of a fascia of house in about 10-15 years if growing in ideal conditions. It does not require pruning, but if it is outgrowing it's allotted space, the best time to prune the climbing Hydrangea is after flowering in late summer, when it can be trimmed to fit the space. The flowers are produced on last year's wood, which means if it is pruned earlier in the year before flowering, the flowers for that year will be sacrificed.
The climbing Hydrangea is a very reliable plant, flowering every year with lovely, frothy, creamy white flowers and bright, almost lime, green foliage. The climbing hydrangea is fully hardy which makes it suitable for growing anywhere in the UK.
