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?

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.
