Hydrangeas that are blue are not necessarily better than pink ones. But the color is so rare–”hydrangea blue” is not a hue that belongs to any other plant or any other anything in the world–that that how could you not want a splotch of it growing against your picket fence?
And what if I said you could change your everyday-pink hydrangeas into moody blue ones–not overnight, of course, but with barely any more effort than you expended back in fourth grade on your science fair project?
Here’s how to change hydrangeas’ color.

Hydrangea blue: How exactly do you describe this particular shade? It is somewhere between violet and blue, existing in that shimmery space where color collides with silver.
