So
@GoMig-21 maybe I've just not been noticing my surrounding for the last few decades but this year it seems almost everybody has blue Hydrangeas.
Now the funny thing is when I first bought my house back in 2006 my mother gave my wife and I something that looked like this:

2 tiny pots..each with a single blue hydrangea.
This is the conversation that went with it...
Me: "hmm I never saw a big blue flower before..but hey didn't we have these but in white"
Her: "Yes, and I tried adding copper to the soil to turn them blue"
Me: "Why didn't you just get blue ones?"
Her: "They are hard to find...and they die more easily than the white ones"
Me: "oh..
nice..well...I'll put them on the dining room table...."
Her: "No you aren't...you are planting them outside...like right now...one on each side of the front door"
Me: "but...they are not even a foot tall..they are going to get choked out by all the other stuff that's over 2 feet high..and you just said they die easily"
Her: "Then plant them in the backyard and transplant them to the front when they get big"
Me: "okay..I can do that..there's actually some room on the side of the house near the back at the end of the rose bushes"
Her: "just remember to do it..people will be stopping their cars in front of your house in amazement"
Me: "Well certainly this blue color should attract attention"
So 18 years later the two plants are huge...even some purple too.
Driving around
I just noticed my area of town is full of blue hydrangeas. Probably every 3rd house has them to the left and right of the front door. It looks really really really nice. Except one house still has them on the side near the back because somebody didn't transplant them.
