Guillermina Jiménez Chabolla (16 August 1930 – 25 November 2020) known professionally as Flor Silvestre, was a Mexican singer and actress. She was one of the most prominent and successful performers of Mexican and Latin American music, and was a star of classic Mexican films during the Golden Age of Mexican cinema. Her more than 70-year career included stage productions, radio programs, records, films, television programs, comics and rodeo shows. Famed for her melodious voice and unique singing style, hence the nicknames "La Sentimental" ("The Sentimental One") and "La Voz Que Acaricia" ("The Voice That Caresses"), Flor Silvestre was a notable interpreter of the ranchera, bolero, bolero ranchero, and huapango genres. She recorded more than 300 songs for three labels: Columbia, RCA Víctor, and Musart.
