I planted 30 Blue Glads this spring along with 30 white and 30 red. What stumped me was the fact that all 30 blue DIDNT bloom blue at all but bloomed a purplish pink color instead. My question is, could soil ph cause the color difference? If I recall with Hydrangea changing the ph will change color from blue to pink or pink to blue.
