Forget me not
My favorite thing about Forget-Me-Nots is that they change color depending on the acidity of the soil so you can get pink or purple ones growing right next to the blue ones.
These are my favourite flowers.
Forget-me-nots also change colour after they become pollinated. It’s a sign to the insects to keep moving, and not to waste time there.
So a blue forget-me-not, once it’s been pollinated, may change to a pale pink to a white colour; which is another reason for such stark colour variations in small areas.
