Hydrangea is also used as the common name for the genus; some (particularly '' H. macrophylla'') are also often called hortensia. The genus was first described from Virginia in North America, but by far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs tall, but some are small trees, and others lianas reaching up to by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. The flowers of many hydrangeas act as natural pH indicators, producing blue flowers when the soil is acidic and pink ones when the soil is alkaline.

It is a small- to medium-sized, multi-stemmed, deciduous shrub up to tall that is native to the eastern United States. Description The inflorescence is a corymb up to wide. Showy, sterile flowers are usually absent or if present they are usually less than 1 cm in diameter on the edge of the panicles. Flowering occurs May to July. Fruit is a ribbed, brown capsule about 2 mm long. Many are produced in October and persist through the winter. The leaves 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". Sm ...
