Calcicola
/kal-SIK-oh-la/🏷️ Taxonomy●●● Advanced
A soil-preference epithet indicating the plant grows on or strongly prefers calcareous (lime-rich, alkaline) soils — chalk grasslands, limestone pavements, and alkaline clay. Calcicole plants often fail or chlorose in acidic soils and are reliable indicators of underlying limestone geology.
Etymology
From Latin calx/calcis (limestone, chalk) + colere (to inhabit, to cultivate), meaning "inhabitant of limestone."
Example
“Sesleria albicans and many orchids including Ophrys apifera are strict calcicoles, thriving only on the thin, alkaline soils over chalk and limestone that this epithet signals.”
