'''''Mimosa''''' is a [[genus]] of about 400 species of herbs and shrubs, in the subfamily Mimosoideae of the legume family [[Fabaceae]]. The most curious plant in the genus is [[Mimosa pudica]] or '''sleeping grass''' because of the way it folds its leaves down when touched or exposed to heat; many others also fold their leaves in the evening. It is native to southern [[Mexico]], [[Uruguay]] and [[Central America]] but is widely cultivated elsewhere for its curiosity value, both as an indoor plant in temperate areas, and outdoors in the tropics. Outdoor cultivation has led to [[weed]]y [[invasive species|invasion]] in some areas, notably [[Hawaii]].
Members of this genus are among the few plants capable of [[rapid plant movement|rapid movement]]; examples outside of ''Mimosa'' include the [[Telegraph plant]], and the [[Venus Flytrap]].
The genus ''Mimosa'' has had a tortuous history, having gone through periods of splitting and lumping, ultimately accumulating over 3,000 names, many of which have either been synonymized under other species or transferred to other genera. In part due to these changing circumscriptions, the name "Mimosa" has also been applied to several other related species with similar pinnate or bipinnate leaves but now classified in other genera, most commonly to ''[[Albizia julibrissin]]'' (Silk Tree) and [[Acacia|''Acacia dealbata'']] (Silver Wattle).
In [[Russia]], [[Italy]] and other countries it is customary to present women with yellow mimosas (among other flowers) on [[International Women's Day]] ([[March 8]]). This flower is from the ''[[Acacia dealbata]]'' (Silver Wattle), which is not a true ''Mimosa''.
