Hydrangeas

So far our garden has turned up lots of pink flowers! So it was no surprise when then the hydrangeas finally started showing some colour... pink!  but as they've continued to come out, we have purple too (much to my apprentice gardeners delight)... and then.... BLUE! I've been (not-so-secretly) hoping they would be blue, so to have a couple on the bush be a pretty shade of light blue is better than none, right?  Next year I think I will do some research and see if I can get them all blue.

edited to add: husband's comments " are these real or plastic? they're just awesome, the first real blue flower I've seen."
