Ajania pacifica, the Gold and Silver Chrysanthemum (1 of 2)

From the Introduction to Garden Plants of Japan by Ran Levy-Yamamori and Gerard Taaffe:

“There are… significant historical difference between gardening in the East and the West. Japan does not have a history of botanical and horticultural exploration to match that of some European nations especially Britain and, more recently, the United States…. The traffic in plants was almost solely in the one direction, from Japan to the West.

“The Japanese did not need to go exploring far afield, seeking sea passages to spice islands, or new homes for breadfruit or rubber trees. For Japanese connoisseurs it was enough to nurture and enjoy native plants and their cultivars. Japanese nurserymen did not have to dispatch explorers to search for new species to assuage the insatiable appetite for novelties that drove so much of European and North American horticulture for three centuries.”

From “Herbaceous Plants” in Garden Plants of Japan by Ran Levy-Yamamori and Gerard Taaffe:

Ajania pacifica (syn. Dendranthema pacificum). Japanese: iso giku. Distribution is limited between Cape Inubo in Chubu Prefecture and Cape Omae in Shizuoka Prefecture and on cliffs along Izu Peninsula directly above the sea, growing along the coast, beside roads, and on banks in poor soil. A rhizomatous perennial. Unusual because it has no ray flowers only tube flowers…. Flower heads small, 1.5 cm in diameter, tube flowers yellow, densely packed, numerous, each 5 mm in diameter. Grows in poor soil but good drainage is essential. Propagated by stem cuttings. Hardy to Zone 7….

“This flower has been long cultivated and is frequently used for making chrysanthemum dolls (kiku ningyo). Life-size historical figures are decorated with chrysanthemum flowers. Hirakata Park in Osaka puts on a magnificent display every autumn.”


Hello!

It was good that I still had a few batches of Aster family photos left to work on from trips I took to Oakland Cemetery in November and December 2025 — because 2026 so far hasn’t been very conducive to outdoor photography. Two Atlanta-style snowstorms (using that word loosely) bracketed by windy weeks of rare single-digit temperatures, and days and days (and days!) of rain kept The Photographer mostly indoors, and we are just this week shifting toward more seasonable conditions and temperatures. I noticed over the past couple of days that a plum tree across the street from my house has started producing flowers — casting a pink glow on the buildings around it — so that also means that some of the late winter/very early spring blooms are starting to make their appearance, and those at Oakland are already likely posing for upcoming photoshoots.

This is the first of two posts with photos of a distinctive chrysanthemum called Ajania pacifica, which — like Tanacetum coccineum that I’ve previously written about (see Technicolor Tanacetum (1 of 4)) — has undergone reclassification several times and can be found under the scientific names or synonyms Dendranthema pacificum and Chrysanthemum pacificum. It’s commonly known as the Gold and Silver Chrysanthemum, Silver and Gold Chrysanthemum, or Pacific Chrysanthemum — this last name connecting to “pacifica” or “pacificum” and to its native origins in regions on the Pacific Ocean, like Japan.

Its physical appearance is quite unlike many chrysanthemum-adjacent members of the Aster family, which tend to grow outward in low-lying branch segments that mass together and make it difficult to distinguish individual plants. Each Ajania pacifica plant, instead, looks like a wee shrub all on its own, with flowers that organize in compact clusters at the top of rows of large, flat leaves tinged with silver-white brushstrokes along their edges — coloration alluding to the “silver” component of two of its common names.

These characteristics make the plant easier to identify with precision, and the plants, when positioned closely together like this…

… produce a carpet of leaves and flowers that is dense and compact, like a cloud you might think you could walk on that attracts a large quantity of pollinators — some of which you can see (ladybugs, bees, and fritillaries) in the first photos below.

Each plant is quite sturdy on its own, as the stems are thick enough to support the large crown of flowers, which makes it especially suitable for the use noted in the second excerpt at the top of this post: “This flower has been long cultivated and is frequently used for making chrysanthemum dolls (kiku ningyo). Life-size historical figures are decorated with chrysanthemum flowers.” Click the link to kiku ningyo if you’d like to read more about the Chrysanthemum Doll Festivals, or click here to see some typical images.

The first excerpt above may seem unrelated to the second, but I paired these selections intentionally. As I dug into the history of chrysanthemums, I learned that they aren’t native to either the United States or most of Europe, despite how common they’ve become and the extent to which they’ve adapted beyond China, Japan, or other East Asia regions. This description of the one-way traffic of plants from Japan to Europe anchors us initially to European botanical expeditions, especially those that begin in the Victorian era and extend into the early twentieth century. To better understand both the botanical and cultural history of chrysanthemums, though, we need to shift our anchor from a Western or European perspective to an Eastern or Asian one, as the authors allude to in the second paragraph of that excerpt.

Chrysanthemums had been grown, bred, and become embedded in Asian culture for hundreds of years prior to being fetched by European explorers. The European (and later North American) Victorian era was one punctuated by boundless acquisition and cultural absorption of artifacts from “exotic” regions — plants among them — and a lot of the readily available research about native Asian plants tends to be presented from a Western or European perspective. Here, for example, is an excerpt from The Garden Triumphant: Victorian Garden Taste by David Stuart that explains the role of botanical expeditions as the driver of plant mobility between Asia and Europe:

“The Victorian flora was unique. It was unique in its richness, as well as for its newness. The most amazing welter of extraordinary plants poured into Britain from all over the world, whether orchids, waterlilies, or calceolarias (many from the jungles and prairies of South America), exquisite alpine plants from the mountains of Africa or Northern India, and wonderful garden plants that had already been cultivated for centuries in China and, even more especially, Japan. The speed of introduction was entirely new, too, though occasional new garden plants had been arriving at least since Roman times. There was a major burst of new introductions with the discovery of the Americas in the fifteenth century, and minor bursts following the development of trade links with the Orient in the sixteenth century, and China and India in the seventeenth. As European explorers, merchants and collectors began to move inland from the coasts on which they had established themselves, the interest in new garden plants expanded throughout the eighteenth century….

“A plant associated with one of the major ‘aesthetic’ vogues of the Victorian period is now in almost every garden. The chrysanthemum, though a garden plant in China and Japan since ancient times, first arrived in Europe in 1689 (these first plants were from Japan). Oddly, for the plants are usually pretty tough, the first introductions were soon lost, only to be reintroduced in 1789. The enthusiasm for them started about 1800, and soon reached ‘craze’ proportions…”

With its origins in the heyday of Victorian garden cemetery development, Oakland maintains fidelity to those Victorian origins with landscaping that includes not only various chrysanthemum species but a large (and expanding) variety of plants native to China, Japan, or other Asian regions. As new growth and flowering takes place each spring, the Asian influence is evident and explicit: blooms will appear on plants like anemone, azaleas, camellia, dogwoods, plums, and quince — to name just a few of those I photograph and write about here. Many of these plants have native origins in Asia and were swept into Europe and the United States in conjunction with plant exploration, so we can find historical and cultural connections that take us from ancient China and Japan, to Great Britain and other parts of Europe, to the Americas, and to Oakland Cemetery. As I photograph and write about these plants over the next few months, I’m planning to dig further into their Asian botanical history — a new area of research for me that I hope will present a more comprehensive picture of the threads connecting plants and their cultural significance across many more generations and geographic regions.

Chrysanthemum Pastels

From “History of the Chrysanthemum” in The Chrysanthemum: Its History, Culture, Classification, and Nomenclature (1885) by F. W. Burbidge:

“The first chrysanthemum that ever flowered in England bloomed in Colville’s nursery, in the King’s Road, Chelsea, in 1795, the plant having been obtained originally from M. Cels, the celebrated nurseryman, of Paris. At this time, and for some little time afterwards, botanists had a contest as to its botanical position; some of them contended that it was one of the Camomiles (Anthemis), whilst others declared that it was unmistakably a Pyrethrum or Feverfew, but at last it was decided that it should be called Chrysanthemum, from chrysos, gold or golden, and anthos, a flower….

Sabine, who was secretary to Horticultural Society at the beginning of the present century, says, however, that Chrysanthemums had been grown in Holland nearly as far back as the year 1688; but, singular to say, in 1821 no gardener in Holland knew anything of them….

“In 1808 their cultivation had increased to some nine or ten varieties, and it went on increasing, many varieties being collected for the Royal Horticultural Society in China and Bengal in 1821 by Mr. Parks. At the end of 1825 the number of varieties seems to have been increased to 48, and in 1826 Sabine writes most cheerily concerning their rapid progress, and of an astounding large exhibition of them being held in the society’s gardens at Chiswick, in which were shown over 700 plants in pots….

“The first sport from the original variety was noted in 1802, in which year Mr. Colville, of Chelsea, sent to Chiswick a pale pink variety, which had sprung from a sort called Changeable Buff. It is curious to note names given to some of the varieties about this time. Let one or two be given for curiosity’s sake: Early Blush, Park’s Small Yellow, Blush Ranunculus, Curled Blush, Tasselled Lilac, Two Coloured Red, Double White Indian, Yellow Indian, Waratah, Quilled Pink, Pale Purple. These names, which in a sense give the characteristic of some of them, seem to indicate that in what are now called the show varieties, which are largely of the strain of
Chrysanthemum sinense, there was the same special singularities as are to be seen now….”

From “American History of the Chrysanthemum” in The Chrysanthemum: Its Culture for Professional Growers and Amateurs (1905) by Arthur Herrington

“There is no authentic record, in fact, not even a tradition as to whom we are indebted for the first introduction of the Chrysanthemum to America, yet it must have been brought, or sent, to this country quite early in the last century.

“The New England Farmer of November 20, 1830, reports on some Chrysanthemums exhibited before the Massachusetts Horticultural Society by its recording secretary, R. L. Emmons, on November 20, and gives a list of varieties, as for example: Tasseled White, Park’s Small Yellow, Quilled Lilac, Quilled White, Golden Lotus and others, and from the similarity of the names to those already mentioned in the English collections, their origin is clearly indicated.

“The late Peter Henderson was the first to introduce into this country, direct from Japan, some of the best varieties known at that time, 1803, which were on exhibition in New York and Philadelphia in 1864…. By those introductions, Peter Henderson kindled the flame which… gave the first impetus to Chrysanthemum culture in America….”


Hello!

The chrysanthemums in this post (taken at Oakland Cemetery in December 2025) remind me of the plant’s ancient origins: with lighter colors that were originally yellow or white, the typical yellow/orange center structures, and their long, thin petals, they mirror the garden or florist’s chrysanthemums that have been known for centuries, and have proliferated in gardens and flower arrangements throughout that entire time. These plants are most likely hybrids based on Chrysanthemum ร— morifolium and Chrysanthemum indicum, with colors tweaked over generations so that each flower reveals softly blended yellow, pink, peach, and orange colors. My favorites of this series are the first three — where I managed to capture a hoverfly fully in focus, and where (if you enlarge the image) you can see its exceptionally big bug-eyes, its distinct mimicry of wasp-like striping, and even that it is fetching nectar from the flowers.

We were supposed to get several inches of snow today, so I expected to be out making snow-people or photographing snow on trees — but we only got spittle flakes and “feels like” temperatures in the lowest possible teens. So instead of venturing outside, I went hunting for some “origin stories” about chrysanthemums — and was thrilled to discover and reproduce excerpts at the top of this post from books published in 1885 and 1905 that describe the plant’s introduction to both England and the United States. More fun than snow! ๐Ÿ™‚

Technicolor Tanacetum (4 of 4)

From “Pyrethrum” in A History of Entomology (1931) by E. O. Essig:

“The use of pyrethrum as an insecticide was early held as a secret in Transcaucasia where the plants, locally known as Persian camomile, flea-grass, or flea killer, grew wild in the Caucasus Mountains…. An Armenian merchant, Jumtikoff, who traveled through this region about 1807 or 1817, noted the value of the prepared powder and transmitted the information to his son who prepared the insecticide in sufficient quantities for export in 1828. The plant was soon afterwards introduced from the Russian Caucasus into Alexandropol and subsequently into Germany, where its value was quickly recognized. A powder was made from the dry flower heads and an infusion from the dry leaves. A volatile oil is the active principle as an insecticide….

“The Caucasian plant was generally known as
Pyrethrum roseum and is now referred to as Chrysanthemum coccineum…. The material made from this plant was commercially called Persian insect powder. In Dalmatia, Jugoslavia, a similar insect powder was produced and as carefully guarded as a secret. It was known in the trade as Dalmatian insect powder and was produced from a plant, Pyrethrum cinerariaefolium, claimed to be a native of that region. It was many years before seeds could be procured to grow either of these plants elsewhere.

“The powder from the Caucasus of Persia and also from Dalmatia was introduced into France to destroy household insects about 1850. Some raw material was secured a few years later and it was definitely determined that the powder from the Caucasus was the best. Accordingly in 1856 seeds were procured from the latter place and sown on September 15, 1856, and the few plants raised produced enough seed to establish the industry in France in 1857…. The industry in France was carefully guarded to prevent the dissemination of seeds to other countries.

“G. N. Milco, a native of Dalmatia, a resident of Stockton, California, and afterwards a member of the State Board of Horticulture of California, secured a few seeds from Gravosa in 1876, which he tried out and found successful. The species grown by him was considered to be
Pyrethrum cinerariaefolium… by most of the writers of that time…. Soon after its introduction, Milco organized the Buhach Producing and Manufacturing Company at Stockton….”


Hello!

This is the fourth of four posts with photos that I took in late November and the first two weeks of December, of Aster family members that I identified as Tanacetum coccineum. The first post is Technicolor Tanacetum (1 of 4); the second post is Technicolor Tanacetum (2 of 4); and the third post is Technicolor Tanacetum (3 of 4). The photos in this post continue to show the presence of multiple flowers on single stems with distinct colors — something that’s even more visually impressive when the plant blooms in cascading vertical or horizontal clusters.

When I photographed Tanacetum coccineum at Oakland Cemetery and started learning about its botanical history, I had no idea I was going to discover so much intense coverage of the plants’ adoption as an insecticide — which stretches from its Asian roots three thousand years ago, through our current century.

The development of pyrethrum-based insecticides occurred in Europe and the United States in alignment with growing scientific study of plant characteristics and how to botanically or genetically manipulate them. The excerpt from A History of Entomology by E. O. Essig is noteworthy in that regard: the book is considered a seminal study of the worlds of insects, and the author devotes a consequential chapter to the development of the insecticide from Tanacetum coccineum (previously called Chrysanthemum coccineum or Pyrethrum roseum), covering it from the early nineteenth century to the first decades of the twentieth century.

Essig’s account is one that includes elements of a good capitalist greed story, including secrecy, closely guarded manufacturing secrets, and intense competition to capture and flood markets with proven insect control capabilities that would extend from crop management to household use. These characteristics, of course, align with European and American industrialization, but the extension to household use meant that pyrethrum-based insecticides could hook into the burgeoning markets for consumer-oriented convenience products for which the period between the 1850s and 1950s is economically notable.

In his pyrethrum history, the author includes this 1881 Buhach Producing and Manufacturing Company advertisement…

… directed at property owners seeking to banish bugs from their homes. When I saw that advertisement — with its cloud of fanciful insects targeted by pyrethrum mist — I remembered those commercials common in the 1960s and 1970s that featured animated cartoon insects encountering a can of Raid insecticide, as they raced away from the spray screaming and slipping into comas, fading behind the commercial’s well-known branding: “Raid: Kills Bugs Dead!” If you’d like to see some of those commercials, there’s a collection of 125 of them on YouTube going back to 1948, at Raid History Commercials.

This might seem like one of my blogging amusables, but there’s also a connection to the entire pyrethrum/pyrethrin historical thread: Raid, according to its Wikipedia article, initially used a chemical called allethrin, and allethrin — produced in 1949 — was the first synthetic version of the natural insecticide found in Tanacetum plants. This enabled subsequent development of a greater volume of more targeted and longer-lasting insecticides; though pyrethrum insecticides are still used and produced, and are often part of organic farming because they’re a natural (rather than chemically created) form of insect control.

Thanks for reading and taking a look!











Technicolor Tanacetum (3 of 4)

From “Pyrethrum” in Flowers and Their Histories by Alice M. Coats:

Pyrethrum roseum (syn. Chrysanthemum coccineum), parent of the hardy border pyrethrums so valuable for cutting, was introduced from the Caucasus at a date variously reported as 1804, 1818 or 1826. At first it was not very greatly esteemed, and indeed the flower as it was portrayed in Maund’s Botanic Garden in 1830 is not very attractive; its pink florets are short in relation to the disc and the whole flower rather overwhelmed by its abundant leafage. Some years later, however, a large rose form was raised by M. Themisterre, a Belgian florist, and was sent by him to Mr. John Salter of Hammersmith, under whose care the centre of the flower was gradually filled and the double form evolved. The varieties raised by this nurseryman were reported to be ‘very numerous, various and beautiful and to include shades of white, pink, red and crimson, singly or in combination’….

“From the early days of its cultivation it was known that this plant was a principal ingredient in the manufacture of Persian insect-powder; and its near relation,
P. cinerariifolia, was used for the same purpose in Dalmatia. The powder is produced from the flower-heads, which are cut just as they are about to open, carefully dried, and pulverized; and ‘Pyrethrum-powder’ as an insecticide has become of increasing importance in the present century. Pyrethrums are grown for this purpose in Kenya, and were considered a crop of the first priority during the last war, for their value in the control of insect pests and the prevention of typhus and other insect-spread diseases….

“The Greek name comes from
pyr, meaning fire, and was originally given to a plant with a hot, biting root, which the early botanists identified with another nearly-related plant, now called Anthemis pyrethrum or Pellitory of Spain. This is rather a tender species, grown here before 1570, but subsequently lost, and reintroduced by Philip Miller in 1732, when he raised some plants from seeds he found sticking to a bunch of Malaga raisins. The root of this plant was formerly used as a cure for toothache; but it is no longer in cultivation as a garden-flower.”


Hello!

This is the third of four posts with photos that I took in late November and the first two weeks of December, of Aster family members that I identified as Tanacetum coccineum. The first post is Technicolor Tanacetum (1 of 4), and the second post is Technicolor Tanacetum (2 of 4).

In the previous two posts for this series, I showed photos of these Painted Daisies where the flowers featured a single dominant color, or the flower petals showed shades or blends of single colors. To illustrate that more precisely, here’s a photo from the second post, next to one from this post.

Both photos show the plants producing more than one flower on a single stem, but those in the photo on the left are quite different from those on the right. On the left, we see the petals all contain shades of the same colors (purples through magenta); whereas the plant on the right produced flowers with distinct colors: one yellow, two orange, one pink, and even — barely visible behind the middle pink flower — one that has purple petals. This variation would not have been a natural accident; it would have been produced intentionally by breeders seeking to develop a variant with these color capabilities. Even those plants that have only produced two flowers (like the first three in my galleries below) show the same capability: they produce one orange and one yellow flower, rather than just varying shades of orange or yellow throughout their petals.

With a breeding history stretching back thousands of years, these color variations depart significantly from the colors present in historically native plants in the Tanacetum and Chrysanthemum genera — which would have been yellow, white, or red (like those in my first post), depending on whether they originated from Asia or the Caucasus region. Blending colors in single flowers, or creating plants capable of producing flowers each with two or three distinct colors, would have occurred through genetic manipulation of hundreds of plant generations where the presence of certain color traits was selectively emphasized.

The plant we now call Tanacetum coccineum (previously known as Chrysanthemum coccineum and as Pyrethrum roseum) has had a long botanical history through Asian and Western cultures, with Chinese chrysanthemum breeding known to have occurred as far back as 1500 BC.ย  As I noted in the first post in this series, there’s a separation reflecting how differently Tanacetum coccineum was represented in botanical history: it was likely not distinguished from chrysanthemums in ancient Chinese or Japanese culture, and wasn’t separated from the Chrysanthemum genus until the twentieth century, when the names Chrysanthemum coccineum and Pyrethrum roseum began to fade from botanical literature. The quotation at the top of this post — from Alice Coats’ Flowers and Their Histories, published in the mid-twentieth century while these name changes were in flux — partially addresses the name ambiguities (which we’re used to by now, right?). While its names vary, however, there is something common to every accounting of Tanacetum that I’ve seen so far: the use of its chemical components as insecticides, or as the basis for manufactured insecticides, embedded throughout the entire 3000-year period where humans have documented the plant’s history. We’ll take a look at the significance — and uniqueness — of those historical threads in the fourth post in this series.

Thanks for reading and taking a look!









Technicolor Tanacetum (2 of 4)

From “The Killing Plants” in Dangerous Garden: The Quest for Plants to Change Our Lives by David C. Stuart:

“Various tanacetums, including the herbaceous red or pink Tanacetum coccineum familiar in our gardens, yield [a] popular insecticide. T. cinerariafolium, in particular, is widely farmed for its pyrethrum. This substance rapidly kills aphids and caterpillars. It also kills beneficial arthropod predators such as lacewings, hoverflies and ladybird larvae. However, as it decays rapidly in air, vanishing within twelve hours, plants sprayed in the evening will not poison bees alighting on them the following morning. It is one of the oldest and safest insecticides available. The pyrethrum paralyses insects almost immediately, to spectacular effect. Many of the immobilized insects later recover.”

From The Light Eaters: How the Unseen World of Plant Intelligence Offers a New Understanding of Life on Earth by Zoe Schlanger:

“All around me are complex adaptive systems. Each creature is folded into layers of interrelationship with surrounding creatures that cascade from the largest to the smallest scale. The plants with the soil, the soil with its microbes, the microbes with the plants, the plants with the fungi, the fungi with the soil. The plants with the animals that graze on them and pollinate them. The plants with each other. The whole beautiful mess defies categorization….

“Plants are the very definition of creative becoming: they are in constant motion, albeit slow motion, probing the air and soil in a relentless quest for a livable future….

“A life spent constantly growing yet rooted in a single spot comes with tremendous challenges. To meet them, plants have come up with some of the most creative methods for surviving of any living thing, us included. Many are so ingenious that they seem nearly impossible for an order of life weโ€™ve mostly relegated to the margins of our own lives, the decoration that frames the theatrics of being an animal.”


Hello!

This is the second of four posts with photos that I took in late November and the first two weeks of December, of Aster family members that I identified as Tanacetum coccineum, though they are similar in appearance to the Chrysanthemum genus plants Chrysanthemum ร— morifolium and Chrysanthemum indicum. The first post is Technicolor Tanacetum (1 of 4).

With the photos in this second post, we visually transition from the solid-colored (mostly red) flowers to those where the petals show blended colors, which we can imagine helped give rise to one of the plant’s common names (that is still used today): Painted Daisy. With the last three photos in this post, we begin to see the expression of less blended, more distinctly different colors — which will be even more evident in the remaining series photos.

The first excerpt I included at the top of this post — from Dangerous Garden: The Quest for Plants to Change Our Lives by David C. Stuart — is only six sentences, but those rich sentences tell us a lot about the evolution of plant adaptation and survival strategies. If natural history was a cartoon, you might imagine a group of Tanacetum plants huddling together 300 million years ago to develop a plan for fending off aphid hordes, which — as any gardener who’s seen one of their invasions knows — can be very determined about chomping on a plant’s leaves and stems until there’s not a lot of leaf or stem left.

What more likely would have happened in real life rather than our cartoon, though, is that some Tanacetum plants — probably as a result of a chemical reaction to the aphid invaders — managed to produce a compound that paralyzed the aphids “to spectacular effect.” Those plants thrived better than species members that didn’t produce the compound, and passed the chemical formula to subsequent generations. That this chemical compound — which we humans call pyrethrin, a name that gave rise to the old plant genus name Pyrethrum — evolved over thousands of generations to target specific insect families and dissipate after a few hours are both fascinating elements of the story: the targeting and dissipation ensure that the plants wouldn’t prevent other, more desirable insects from fulfilling their roles as pollinators.

Should you happen to have some insecticide around, you can check the ingredients and find chemicals like bifenthrin or cypermethrin listed. These chemicals are synthetically produced but were modeled after pyrethrins. They were designed to emulate how Tanacetum pyrethrin targets specific insects while being more persistent than the natural compound — which dissipates within hours — so that the insecticide can keep an area clear of undesirable pests for days, weeks, or even months, demonstrating how humans adapted a plant’s evolved defense strategy and modified it to meet the needs of commercial pest control applications.
