Quick watercolor sketch (no drawing) of my garden hydrangea "Endless Summer". It is almost impossible to get my pink hydrangea to turn blue or even lavender. I used aluminum sulfate as directed and just got these lovely pink flowers! I read somewhere that you can also add 1 Tbsp of aluminum sulfate to a gallon of water and use with each watering. I will try try this. I added blue food color to the water of my cut flower - will see how that works!
