Hydrangea

Today's the day …………………………. to change colour

A day at home catching up with things, washing clothes and the like. 

Although for the first time in many weeks, it wasn't possible to dry clothes out on the line in an hour or so.  It's hard to break the habit though - and I did hang them out, only to have to bring them in again even wetter than they started.

This is a hydrangea from a bush in the front garden.  Unremarkable apart from the fact that, for the 27 years we have lived here, the bush has produced pink flowers.  This year they are a very nice blue colour.

Anyone know how that could have happened ……………………..?
