There are over 26000 different daffodils registered; of these, it is thought that only about 10% are available commercially.
The National Gardening Association database has 26669 Daffodils listed with 7109 photos.
The most widely sold daffodil of all time is the large cupped yellow daffodil 'Carlton'. It is still available. The world's leading growers of daffodils are England, Netherlands, then USA (mostly on the west, north west coast areas of California, Oregon, and Washington).
A well-drained, sunny spot, with excellent drainage is best. Daffodils can grow in semi-shaded areas, but thrive in sunny areas.
Daffodils need plenty of water during their growing season and like to be dry in summer.
Daffodils do well with minimal fertilizer. The many large, naturalized fields of Daffodils attest to this fact, so enjoy with minimal effort in your own gardens.
The bulbs make their next year's bloom after flowering, so never cut the foliage until it begins to yellow (usually late May or June). The bulbs are receiving nutrients for next years' growth from the foliage.
They may be lifted and divided after 3-5 years if they are getting too crowded.
Daffodils may be forced for inside bloom. After forcing, you can plant them outside in the ground to enjoy for years to come.

As an example - the daffodil 'Roulette - 2 _ _W - YYO and the daffodil Altun Ha - 2 YYW - W_ _.
The number (which starts the code) is which daffodil Division it is assigned to, in both examples it's a 2 which translates into Division 2, Large-Cupped Daffodil.
Roulette
The remainder of the code relates to color, the first 3 spaces available is the color of the petals, hyphon, 3 more available spaces. The spaces to the right of the hyphon relate to the color of the cup. 1st example is a blank, blank W. If only one space used, that's the color of the petals, in this case a W which equals white. Hence we now know the daffodil in question, Roulette. has all white petals. YYO completes the first code, this means the cup has a yellow base, a yellow middle and an O for orange rim to the cup.
Altun Ha
Large Cupped YYW, meaning yellow, yellow, white, or yellow tips, yellow body, white base to the petals. Then, the hyphon, W blank blank, meaning white cup.
If the daffodil code read 2 YYW-YYO, we'd have a daffodil with petals of yellow ends and yellow middle, and a white base.. Hypon. YYO meaning the cup is yellow based, with a yellow body and an orange rim.
Conversely a daffodil code might read 1 W - Y, which means Division 1 Trumpet with white petals and yellow cup.
Abbreviations used in Daffodil color codes:
Y - yellow, W - white, R - red, O - orange, P - pink, G - green
