Geum (redirected from Geum (plant))

Geum 

a genus of herbaceous perennial plants of the family Rosaceae. The radical leaves are lyrate-pinnatipartite, while the cauline leaves are tripartite. The flowers are single or in clusters. There are more than 40 species in the temperate zone of the northern (primarily) and southern hemispheres and in the arctic. In the USSR there are seven species. The most common species in damp meadows, shrub thickets, edges of forests, and sparse forests are water avens (G. rivale), with reddish petals, and herb bennet (G. urbanum), with yellow petals. The underground parts of avens contain many tannins and a yellow dye substance. The rhizome is used in folk medicine as an astringent. G. coccineum and G. chiloense, among others, are sometimes grown as ornamentals.
