Hydrangea macrophylla is a species of flowering plant in the family Hydrangeaceae, native to Japan. It is a deciduous shrub growing to 2 meters tall by 2.5 meters broad with large heads of pink or blue flowers in summer and autumn.
Hydrangea macrophylla blooms can be blue, red, pink, light purple, or dark purple. The color is affected by soil pH. An acidic soil (pH below 7) will usually produce flower color closer to blue, whereas an alkaline soil (pH above 7) will produce flowers more pink.
This is caused by a color change of the flower pigments in the presence of aluminum ions which can be taken up into hyperaccumulating plants.
