What is the name of those plants that turn blue, purple, or pink depending on the quality of soil they are in?
thanks!
my pleasure 
Are you planning on growing them? I have two shrubs, one blooming pink at the moment, the other just sending out some nice foliage. I think the latter was a little crowded until recently. Hoping for better results with it next summer.
The most beautiful ones I ever saw were in the Pacific Northwest. Better climate for them than the Midwest, I think, and the soil there probably isn’t as alkaline as mine.
