Hydrangea Blueing Agent 500g:

The red, pink, or blue color of hydrangea flowers is due to the presence of a natural pigment in the plant, delphinidin, absent in white varieties.

For a hydrangea to produce blue flowers, several conditions must converge: in pink or blue varieties, the soil must have an acidic pH, approximately 4.50, and must contain aluminum, which is associated with the plant's delphinidin to give the blue color.
