1. The classification of a daffodil cultivar (cultivated variety) is based on the description and measurements or the classification submitted by the person registering the variety.
3. For the purpose of the description, the daffodil is divided into two regions, the perianth (petals) and corona (cup).
4. The perianth (petals) is described using letters of the color code most appropriate, identifying first the outside edge of the petal, then the middle, and lastly the inside part next to the corona.
5. The corona (cup) is described using letters of the color code most appropriate, beginning with the inside, eye-zone, then the mid-zone and extending out to the edge or rim.
7. In Division 4, double daffodils, the letters of the color code accurately describing the mixture of petals and petaloids follow in proper order, using three, two, or one color codes as appropriate.
8. If the perianth and/or corona are substantially of a single color; a single letter of the color code is used to describe its classification.
Whether of wild or cultivated origin, once a selection has been distinguished by a cultivar name it is normally assigned to Divisions 1-12. Daffodils distinguished solely by botanical name should be assigned to Division 13.
The characteristics for Divisions 5 to 10 are given for guidance only; they are not all necessarily expected to be present in every cultivar assigned to those divisions.
