Jiřina Kaplická née Florová graduated from the Academy of Arts, Architecture and Design under Vratislav Hugo Brunner and František Kysela. Until 1939, she taught drawing in high schools. During the war, she devoted herself mainly to her family, together with her husband, painter and sculptor Josef Kaplický, they raised their son Jan, a future architect. In addition to her designs for bookbindings, home textiles or porcelain decors, Jiřina Kaplická selflessly helped her husband with the realizations. She continuously created and published her scientific illustrations. Although she preferred to work with a brush, she was inspired by the work of the founder of Czech scientific illustration, A. C. J. Corda, Josef Mánes or Karel Svolinský. She followed her green models in the open air, for example in the garden of the Průhonice chateau. Her illustrations have been accompanied by dozens of titles by Czech and foreign publishers. In the aptly named publication Kytice Kytky Kytičky (Albatros, 1986), she supplemented volumes of meadow flowers with poems by Jan Vodňanský, Milena Lukešová and others.
