Hydrangea macrophylla 'Nigra'
The inflorescence, whose colour depends on the pH of the soil, may sometimes seem messy and spotted: this is due to the fact that the immature and mature flowers are distributed on the same corymbs at the same time; but the result, rather than a defect, is a likeable characteristic. The peduncles are reddish, and the most noticeable feature of this plant is the dark brown or black colour of the stems, which makes its identification quick and easy. It is imported from China, like H. m. var. mandshurica.
