Flowers grow at the top of a long leafless stem, usually in groups but sometimes singly.

Native to Europe and the Mediterranean area of North Africa, southern Europe and Asia, Narcissus is a large genus that includes daffodils, jonquils and narcissus. There are many categories of narcissus types, and they have been hybridized for centuries. Flower colors are yellow, orange, red-orange, pink, cream and white. Some brightly colored daffodils are golden yellow “Golden Ducat,” pink-cupped “Pink Pride,” yellow-and-orange “Fortissimo” and “Scarlet Gem” with yellow petals and a red-orange cup.
