Jasione montana is a low-growing plant in the family Campanulaceae found in rocky places and upland regions of Europe and western Asia. Common names include sheep's-bit, blue bonnets, blue buttons, blue daisy and iron flower. Due to the similarity of the common name of "sheep's-bit" with that of devil's-bit scabious (Succisa pratensis), it is sometimes called "sheep's-bit scabious" or "sheep scabious", but it is not closely related to the scabious genus (Scabiosa).
This plant is found in the temperate zone of Europe and northwestern Africa. It is a plant growing on heaths and moors in rocky or sandy districts, coastal cliffs, quarries and natural escarpments where the soil is thin. It prefers acid soils and is absent from limestone regions. It is often found on coastal cliffs in association with thrift and kidney vetch and blooms from May to September.
