'''''Jovibarba''''' ("beard of [[Jove]]") is a small [[genus]] of three species of [[succulent]]s in the family [[Crassulaceae]], [[endemism|endemic]] to [[Europe]]. The genus is closely related to ''[[Sempervivum]]'', and was formerly considered a subgenus of it. ''Jovibarba'' have pale-greenish-yellow or yellow bell-shaped flowers with six petals, while ''Sempervivum'' has [[actinomorphic flower|actinomorphic]] flowers with more than six petals. The common name [[Hen and chicks]] is applied to some ''Jovibarba'' species (and also species in several other related genera).
In addition to sexual propagation by [[seed]]s and propagation by [[offsets]], the species ''Jovibarba heuffelii'' also propagates by dividing [[rosettes]].
;Species
Only three species are accepted as distinct by the ''Flora Europaea'':
*''[[Jovibarba globifera]]'' (syn. ''J. sobolifera''; ''Sempervivum globifera'')
*''[[Jovibarba heuffelii]]'' (syn. ''J. velenovskyi''; ''Sempervivum heuffelii'')
*''[[Jovibarba hirta]]'' (syn. ''Sempervivum hirta'')
''Jovibarba globifera'' and its subspecies (subsp. ''hirtum'', subsp. ''allionii'', subsp. ''arenaria'') live in the eastern and southern Alps, the Carpathians and the western Balkans south to northern Albania. ''J. heuffelii'' occurs in the remainder of the Balkans and the eastern Carpathians, southeast of ''J. globifera''. ''J. hirta'' occurs further west, in the southwestern Alps.
