Many of Frida Kahlo's flower paintings contain sexual references, which is obvious in Xochitl, Floer of Life, 1938. The flower here is made up of two very identifiable parts: a red bell-like vagina and a penis received from above.
The title of the painting Xóchitl, is from the Aztec Náhuatl language for "flower", but it also means "delicate thing". Privately, to Nickolas Muray, one of Frida's long time lovers, she referred to herself as Xochitl. She often signed her letters to him that way.
