Geranium macrorrhizum
species of plant
Geranium macrorrhizum is a species of hardy flowering herbaceous perennial plant in the genus Geranium, family Geraniaceae. It is native to the south-eastern Alps and the Balkans. Its common names include bigroot geranium, Bulgarian geranium, and rock crane's-bill.
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) and 'White-ness' have gained the Royal Horticultural Society's Award of Garden Merit.
The plant has been used in traditional herbal medicine. One of the many components of the essential oil is the sesquiterpene ketone germacrone, which has been shown to have in vitro antimicrobial activity against the species Bacillus subtilis. 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.
This brief starts where responsible research should: with the source description of “Geranium macrorrhizum” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q805037. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
