Narcissus ‘Yellow Cheerfulness’ is in Division 4. It stands 12 - 18 inches high and blooms late in the season with double flowers which are less than 1 inch wide. The petals are bright yellow and very broad with a small point at the tip. The corona segments are also bright yellow and are clustered in the center. The bulbs are toxic and will not be eaten by deer or rabbits. The name Narcissus comes from the Greek word for narcotic and is tied to the myth of a young man known as Narcissus who fell in love with his own reflection. When he drowned in the pool where he had been admiring himself, Narcissus flowers grew up around the pool.
