THE INCREDIBLE LITMUS FLOWER
In the course of our work, we came across this rather amazing flower. No, we don't sell this flower as yet. We just thought that you'd like reading about this most unusual member of the flower world.
There is a flower that changes color depending on the soil chemistry.
Hydrangea flowers are blue if the plant is growing in acidic soil, and pink in alkaline soil! The pigment in the flowers is a natural chemical indicator, similar to the chemical that causes litmus paper to change color in acidic or alkaline solutions.
We have been considering growing a handful of Hydrangea flowers in our greenhouses, to use as a general indication of the state of the soil. There are, of course, much more accurate chemical soil tests for this purpose. However, for us flowers are not just a business, but a hobby! This says a lot about the care and effort we put into our work.

We came across this experiment to use red cabbage juice as a pH indicator. You may be interested in trying this:
