Do you know there is a flower with a narcissistic personality?
Common flowers including daffodil, narcissus, and jonquil don't like to share an arrangement with other Spring flowers!
Seriously? Yes! The sap is toxic to other flowers and they will turn their toes up within 24 - 48 hours of being placed in the same vase. Some say that the flower name "narcissus" is linked to the Greek myth of Narcissus, who became so obsessed with his own reflection that as he knelt and gazed into a pool of water, he fell into the water and drowned. In some variations, he died of starvation and thirst as he was unable to leave his own reflection.
So now you know, be careful not to buy a mixed bunch of spring flowers with the narcisstic flower in it! They are such a beautiful flower that they truly do deserve to be displayed simply in vase, without competition from other flowers.
