 The earliest mention of poet's daffodil is likely in the "Historia Plantarum" (VI.6.9), the main botanical writing of Theophrastus (371 – c. 287 BCE), who wrote about a spring-blooming narcissus that the Loeb Classical Library editors identify as "Narcissus poeticus".According to Theophrastus, the narcissus (νάρκισσος), also called leirion (λείριον), has a leafless stem, with the flower at the top.The plant blooms very late, after the setting of Arcturus about the equinox.
