By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. These flowers are produced from early spring to late autumn; they grow in flowerheads most often at the ends of the stems. These Flowers are in different colors but in most species the flowers are white, but in some species can be blue, red, pink, light purple, or dark purple. In these flowers the color is affected by the presence of aluminium ions which are available or tied up depending upon the soil pH. These flowers also have a nickname called 'Change Rose'.
