The purified pigment from lichen (litmus) is used by gardeners to determine the pH (acidity or alkalinity) of soils. The litmus paper strip changes color according to the types of ions present. A predominance of hydrogen ions [H+] is acidic and results in red litmus; hydroxyl ions [OH-] are basic (alkaline) and result in blue. When plants fail to thrive, the reason is often the soil has the incorrect pH for the particular plant. But there is a common plant that behaves like the litmus test.
