The second thing you need to know is something about the various classes of daffodils you'll find listed or on display. Daffodil is the English name for the narcissus. There are many flower shapes and combinations and many variations of the two main daffodil colors-white and yellow. A few new, and still expensive, introductions show light salmon-pink tints in their petals, and many have red in their cups. Daffodil beauty cannot be gauged by price.
Price is determined by the amount of stock available to satisfy the demand.
Some varieties produce new bulbs more prolifically than others and so move more rapidly from collector's items to the general catalog lists. Each daffodil flower has a central part known as an eye, crown, or trumpet, and an outer part called the perianth, which consists of six parts. It is the variation in the proportions and colors of these principal parts that determine the classes. Buy what you can. Order from a reputable dealer and specify late-summer delivery.
