'''''Geum''''' ('''Avens''') is a [[genus]] of about 50 [[species]] of [[perennial plant|perennial]] [[herbaceous plant]]s in the rose family [[Rosaceae]], native to [[Europe]], [[Asia]], [[North America|North]] and [[South America]], [[Africa]] and [[New Zealand]]. They are closely related to ''[[Potentilla]]'' and [[strawberry|''Fragaria'']].

''Geum'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Grizzled Skipper]].

		+	Herbs, with a perennial rhizome, sometimes stoloniferous: root-lvs. crowded, odd-pinnate, the alternate lobes often smaller, terminal ones largest; st.-lvs. few, mostly of 3 lfts. or bract-like: fls. 1-2 in. across, solitary or corymbose or cymose; calyx persistent, its tube nearly hemispheric, usually 5-lobed; petals 5, nearly or quite round, longer than the calyx: fr. bunched on a short receptacle, frequently plumed.— More than 50 species, mostly in temperate and frigid regions.
