The Adonis Flower
according to Bion, is the rose; Pliny (i. 23) says it is the anemone; others say it is the field poppy, certainly the prince of weeds; but what we now generally mean by the Adonis flower is pheasant's eye, called in French goute-de-sang, because in fable it sprang from the blood of the gored hunter.
