Very interesting flower.
"The word 'narcissus' is derived from the Greek word narke, meaning numbness (also the root of the word narcotic); the flower may have been named thus because of the intoxicating fragrance of some species.
In mythology, Narcissus transformed into the flower now named for him because:
'Unable to leave the allure of his image, he eventually realized that his love could not be reciprocated and he melted away from the fire of passion burning inside him, eventually turning into a gold and white flower'
The personality disorder is named after this mythological figure 'who fell in love with his own reflection.'
Yet, the flower also has positive symbolism:
'The most common symbolic meanings attributed to the narcissus flower are rebirth, renewal, and the coming of spring. For that reason alone, it’s the perfect flower for March birthdays. It can also mean good luck, happiness, prosperity, and wealth'"
