For over 35 years my Hydrangea has always been white, but I presume because of the hot dry weather, the soil has changed and produced a lot less leaves and these mottley pink. (I prefer the white).
The weather has not been kind to the hydrangeas this year - mine look leggy !! and the pale pink one is a deep red ! Hope things will be more normal next year !
I like the sharp details you got here
