Narcissus, of Greek mythology, was doomed to fall in love with his own reflection in a pool and to die there for his disdain of those who loved his beauty.
Narcissus is also the botanical name for a genus of hardy, spring-flowering Amaryllis plants native to Europe, North Africa, and Asia. There are many species variants and wild hybrids, most familiar is the daffodil, which itself comes in many varieties. There are two possibly etymologies for the plant name narcissus. The first is that they are named for the character of Greek tragedy who turned into the flower where he died. The second explanation is that the plant for its narcotic properties (narkao meaning to numb in Greek). That word, of course, also presumably having a direct connection with Narcissus.
