Hydrangea arborescens, commonly known as smooth hydrangea, wild hydrangea, or sevenbark, is a species of flowering plant in the family Hydrangeaceae. It is a small- to medium-sized, deciduous shrub up to 3 m (10 ft) tall that is native to the eastern United States.[2]

Smooth hydrangea is widely distributed across the eastern United States—from southern New York to the panhandle of Florida, west to eastern Oklahoma and southeastern Kansas. It is mainly found in moist soils under a hardwood forest canopy and is often common along woodland road banks and streams.[3] It is common in the Delaware River Valley and in the Appalachian Mountains.[2][4]
The inflorescence of smooth hydrangea is a corymb. The showy, sterile flowers are usually absent or if present they are usually less than 1 cm in diameter.[2] Flowering occurs May to July. Fruit is a ribbed brown capsule about 2 mm long; many are produced. The leaves of smooth hydrangea are large (8 to 18 cm long), opposite, serrated, ovate, and deciduous. The lower leaf surface is glabrous or with inconspicuous fine hairs, appearing green; trichomes of the lower surface are restricted to the midrib and major veins. The stem bark has a peculiar tendency to peel off in several successive thin layers with different colors, hence the common name “sevenbark”.[4] Smooth hydrangea can spread rapidly by stolons to form colonies.[7]
This attractive native shrub is often cultivated for ornamental use.[8] ‘Annabelle’ is the best known cultivar of this species; it is one of the most cold hardy of the hydrangeas. The cultivar ‘Grandiflora’ has flowers that resemble snowballs, similar to Viburnum plicatum.

Hydrangea arborescens var. grandiflora from Kashmir,
A snowball like plant but with unlobed leaves nearly orbicular in shape and subcordate at base, cultivated in gardens in Kashmir.

Is this same species? (Images are attached here) I think flower color varies from rose to white. Attachments (1)

Your plant is Dombeya sp., mostly a tropical plant.

…, I think your plant is Hydrangea macrophylla, which is more common in India – the flower color varies from pink to blue, depending
on the acidity of the soil. The pattern of veins on the leaves of the two species is also different – you can see the following pics for
