Galiumis a largegenusofannualandperennialherbaceousplants in the familyRubiaceae,occurring in thetemperatezones of both the Northern and Southern Hemispheres. Some species are informally known asbedstraw.[1]
There are over 600 species ofGalium,[2]with estimates of 629[3]to 650[4]as of 2013. The field madder,Sherardia arvensis,is a close relative and may be confused with a tiny bedstraw.Asperulais also a closely related genus; some species ofGalium(such as woodruff,G. odoratum) are occasionally placed therein.
Genetic variability
[edit]The phenotypic plasticity and genetic variability of this species allows it to be constantly shifting to best fit its environment adjusting life cycles, seed germination, productivity, growth form, freezing tolerance, etc.[5]Herbicides at the recommended amount is not effective enough to decrease catchweed bedstraw biomass or population, twice the amount is needed.[6]
As invasive species
[edit]Cattle and other livestock don't often feed on this plant making it thrive and dominating over other species.G. mollugoin particular, is a thriving invasive species since it can go in and dominate in areas where other alien species wouldn't be able to, growing very fast in best conditions.[7]
