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.
2. Color codes used to describe the color of daffodils are as follows:
W - White or whitish
G -Green
Y - Yellow
P - Pink
O - Orange
R - Red
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.
6. The written format used to describe the classification of a daffodil
is the following:
division designation (number 1-13),
letter or letters of the color code most accurately
describing the zones of the perianth followed by a hyphen,
letter of the color code, most accurately describing
the zones of the corona
For example, Angel's Whisper, in the photo above, is a
Division 5 Yellow-Yellow and is displayed as: 5 Y-Y
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.
Notes
 |
1. 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. |
All Daffodils are classified into one of the thirteen
divisions described below:
Division 1 - Trumpet
One flower to a stem, corona (trumpet or cup) as long or longer than the perianth segments
(petals).
Division 2 - Large Cup
One flower to a stem, corona (cup) more than one third but less than equal to the length
of the perianth segments (petals).
Division 3 - Short Cup
One flower to a stem, corona (cup) not more than one third the height of the perianth
segments (petals).
Division 4 - Double
Daffodils have a clustered cup, petals or both.
There can be one or more flowers per stem.
Division 5 - Triandrus
Usually more than one flower to a stem, head drooping, perianth segments often reflexed
and of silky texture.
Division 6 - Cyclamineus
One flower to a stem, perianth significantly reflexed and corona straight and narrow. Some
exceptions exist.
Division 7 - Jonquilla
Usually several flower heads to a stem, flowers usually fragrant, stem is round in
cross-section and foliage is often rush like.
Division 8 - Tazetta
Usually three to twenty flowers to a stout stem, sweet scented and very short cupped. Perianth segments rounded and often
somewhat crinkled.
Division 9 - Poeticus
Usually one flower to a stem. White petals sometimes stained with the corona color at the
base, small flat cup edged with red. Fragrant.
Division 10 - Bulbocodium
Hybrids
Small flowers resemble a "hoop petticoat" form.
Division 11 - Split Corona
Corona split - usually more than half its length.
| |
a) Collar Daffodils
| |
Split-corona daffodils with the corona segments opposite
the perianth segments; the corona segments usually in two whorls of three |
|
| |
b) Papillon Daffodils
| |
Split-corona daffodils with the corona segments alternate
to the perianth segments; the corona segments usually in a single whorl of six |
|
Division 12 - Other Cultivars
Daffodils not falling into any of the previous categories.
Division 13 - Species
All species and reputedly wild forms.
