Il-Prospero autumnale, magħruf bħala l-Għansartal-Ħarifa, l-Għansar tax-Xitwa jew l-Għansal tal-Ħarifa, l-Għansal tax-Xitwa, hija pjanta perenni mill-familja Asparagaceae.[1][2][3] Din l-ispeċi tinsab fir-reġjun tal-Punent tal-Mediterran mill-Portugall u l-Marokk sat-Turkija fl-Lvant tal-Mediterran.[1][4] Kif ukoll tinstab fil-Kawkasu, fi Franza, fil-Germanja u fil-Gran Brittanja.[1][4][5] Minkejja li l-Prospero autumnale hija kklassifikata bħala speċi waħda, fil-fatt tiġbor fiha ħafna speċi differenti tal-istess ġeneru li jidhru morfologikament simili.[6][7] Kif ukoll hemm diversi poplazzjonijiet tal-istess speċi tal-Prospero autumnale li huma diversi fin-numru ta' kromożomi differenti, fil-morfologija u ibridi bejniethom madwar iz-żona tal-Mediterran.[8][9][10][11]
