From “Narcissus” in Complete Guide to Gardening and Landscaping by Time-Life Books:
“Daffodils are among the best known of spring-flowering bulbs, and although there are only about 70 species in the genus, there are hundreds of hybrids with varying flower forms….
“Members of the amaryllis family, daffodils arise from bulbs and generally have flat, narrow leaves. The flowers are usually nodding and may be white, yellow or bicolored. They are borne alone or several per stem. The bloom consists of a corona, or crown, which is cup- or trumpet-shaped, stands in the center, and may be long and tubular or short and ringlike. The corona is surrounded by six petallike segments that are referred to collectively as the perianth….
“Double Daffodils do not look like typical daffodils; there is usually no defined corona but instead a cluster of petaloids at the center, and there may be more than one bloom per stem. Plants range from 14 to 18 inches tall, and blooms are from 1 to 3 inches across. ‘Acropolis‘ grows 18 inches tall, usually blooms late in the season, and is white with red and white petaloids. ‘Cheerfulness‘ bears clusters of double white flowers that are fragrant. ‘Tahiti‘ grows 16 inches tall and usually blooms late in the season; it is yellow with red petaloids. ‘White Marvel‘ has pure white, double blooms on 14-inch plants. ‘Pencrebar‘ is a miniature that grows to 10 inches and has 2-inch, all-yellow flowers.”
From “Spellbinder” in An Indian Summer: 100 Recent Poems by Sacheverell Sitwell:
And as if from islands further west,
deeper into the mists,
Not sea-green daffodils,
but a green-yellow I had not known before,
Except in primroses,
and then only in shadow near to the yews;
A green-yellow like starlight all morning through….
But I have noticed that in a day or two
the petals of this daffodil become white-pointed,
That their flanges where they join the tube
and was never sign of needle or thread,
Are white-stained,
that the trumpet has its bell-mouth whitened too,
As if from sleeping in starlight
that gives pallor and engenders dreams
So,
folded in its own greenness,
This cluster,
this isle of daffodils,
Dreams,
and soon dies away
Hello!
Here we have photos of three double daffodil variants from Oakland Cemetery’s gardens, that I took during the same photoshoot as the white doubles I posted previously (see White Double Daffodils (1 of 2) and White Double Daffodils (2 of 2)).
Unlike most of the daffodils I’ve encountered this spring that usually appear in large batches (see, for example, Rise of the Yellow-Yellow Daffodils (1 of 2)), these doubles appear to be rather solitary figures, with just a few friends or fans hanging around nearby. Doubles are less common than more “traditional” daffodils (it seems), and their genetics may simply dictate that they’re less likely to propagate wildly on their own, as their more promiscuous relatives tend to do. I don’t think I found more than a dozen individual stems of these three varieties, despite scouring the gardens for more and returning for a second hunting expedition. But while I didn’t find more that looked like these, I did come across yet another set of double white daffodils, similar to the Paperwhites I previously posted yet with a different flower structure and more orange color where the trumpets would have been in their ancestors. I’m still working on those photos and will post them up in a few days.
Those toward the center of the galleries below — with white petals and yellow-orange centers — are nearer in design to daffodils you might find anywhere with white petals and orange trumpets. But take a closer look and you can imagine how botanical engineering might have helped an orange trumpet evolve into overlapping petals with both colors of the flower reflected in the new structure. While the chemical and botanical work involved in creating these changes is beyond my knowledge or ability to explain well, it’s probable that variants like these started as a mutation — the appearance, perhaps, of a daffodil with malformed petals or a multicolored trumpet — which a horticulturalist could then foster by selective breeding. I learned from my research assistant that producing a successful variant like this — and producing one that can continue to be propagated — may take five years or more. And the evolutionary process does indeed start with the appearance of a natural mutation:
Mutations are the original source of what we now cultivate as double daffodils, and this process is a perfect example of how human observation and selective breeding can transform plant characteristics.
In nature, genetic mutations occur spontaneously and randomly. These mutations can cause various changes in plant structures, including: additional petal formation; transformation of reproductive organs into petal-like structures; and alterations in color or flower shape.
For double daffodils, these mutations typically involve a genetic change that causes: (1) stamens to transform into petals; (2) the corona (trumpet) to develop additional petal-like structures; or (3) an increase in the number of flower parts.
Early horticulturists like Peter Barr would meticulously examine large populations of daffodils, looking for these rare spontaneous mutations. When they found a plant with an unusual flower structure — like one with extra, more complex petals — they would carefully isolate that specific plant, propagate it through bulb division, and selectively breed it with other plants showing similar characteristics.
Think of it like a botanical treasure hunt. Most daffodils would look “normal,” but occasionally, a single plant would emerge with a dramatically different flower structure. These rare mutations became the foundation for entire new varieties of daffodils. The process is similar to how we’ve developed many cultivated plants — through patient observation of natural variations and deliberate selection. Double daffodils aren’t created in a laboratory, but emerge from careful observation of nature’s own genetic experiments.
Similarly, those with yellow and green petals are genetic variations of light green daffodils, with selective breeding and genetic modifications undertaken to enhance the (relatively rare among flowers) green colors along with gradually replacing the trumpets with a series of flower petals.
As you can see from the photos, the first batch of yellow and green doubles open in rather strange formations and present distinct bands of color that almost look like stripes; whereas those toward the end of this post have more orange with splashes of green. They, too, have a distinctive appearance as they open with a large number of piled flower petals, looking a bit like a shredded pom-pom — and, to say the truth — I first thought I was looking at a dead flower until I handled one of them and realized that they were as fully alive as they could be.
Thanks for reading and taking a look!
