'''''Jaborosa''''' is a genus of flowering plants in the family Solanaceae, the nightshades. There are about 23 species,<ref name=tetta>{{cite journal |last1=Tettamanzi |first1=M.

==Description== Most ''Jaborosa'' are rhizomatous perennial herbs except ''J. bergii'' and ''J. sativa'', which are annual or biennial.<ref name=chia/>
==Ecology== ''Jaborosa rotacea'' is pollinated by flies, and ''J. runcinata'' is pollinated by moths.<ref name=chia/> Sphingid moths feed on the nectar of ''J. integrifolia''.<ref name=vesp/>
==Chemistry== Like plants in several other genera of the Solanaceae, many ''Jaborosa'' species contain steroid-derived compounds called withanolides.<ref name=nico>{{cite journal |last1=Nicotra |first1=Viviana E. |last2=Ramacciotti |first2=Natalia S. |last3=Gil |first3=Roberto R. |last4=Oberti |first4=Juan C. |last5=Feresin |first5=Gabriela E. |last6=Guerrero |first6=Cecilia A. |last7=Baggio |first7=Ricardo F. |last8=Garland |first8=M.
