Clusius called it Narcissus Jacobeus. A. de Jussieu called it La Belladone. Portuguese gardeners of the second half of the 18th century called it Belladonna Lily. Sprekelia formosissima is the Mayhua, Amacayo and Azcal Xochitl of the West Indies (Central and South America). Its bulbs have been used to prevent hair loss.

Sweerts described his flower as "sanguine", but Parkinson seems to have copied the figure for his own yellow Narcissus Trapezunticus. The DeBry illustration has thicker tepals, suggesting the Lilionarcissus rubeus indicus of Aldinus, which was also known as "Narcissus Jacobeus". Ferrari called the same plant Narcissus Indicus latofolio narcissino, flore rubro, liliaceo, which allowed for confusion with the plant Clusius had named Narcissus Jacobaeus latifolius Indicus rubro flore.
