Geranium macrorrhizum

Geranium macrorrhizum is a species of hardy flowering herbaceous perennial plant in the genus Geranium, family Geraniaceae. It is native to the South east Alps and the Balkans.[1] Its common names include bigroot geranium,[2] Bulgarian geranium,[2] and rock crane's-bill.[3]

It has five-lobed (palmate) leaves that are aromatic when crushed, with pale pink flowers in summer. It is cultivated as an ornamental plant in temperate regions, where it is used as a flowering groundcover, with named cultivars selected for flower colors from white through pink to magenta. The cultivars 'Ingwersen's Variety' (pale pink)[4] and 'White-ness' [5] have gained the Royal Horticultural Society's Award of Garden Merit.[6]

The plant has been used in traditional herbal medicine.[7] The name for all types of geraniums in general in the Bulgarian language is derived from the word здрав, which can translate as 'healthy', among a few related concepts. An essential oil from it is also used in aromatherapy. In addition to oils, it contains flavonoids, sesquiterpenes, phenolic acids, pigments, vitamins, and mineral salts.[citation needed]

One of the many components of the essential oil is the sesquiterpene ketone germacrone, which has been shown to have a high and selective antimicrobial activity against the species Bacillus subtilis.[7]
