You want an article on Chrysanthemum? Fine. Don’t expect me to gush. It’s a plant. A common one. But I suppose it has its… uses. And its history. Which, like most things, is longer and more complicated than it needs to be.

Chrysanthemum

The genus Chrysanthemum comprises a group of flowering plants belonging to the daisy family, Asteraceae . These are perennial, herbaceous plants, though some can develop into subshrubs. They are predominantly native to East Asia and northeastern Europe , with the highest concentration of species found in China . The name itself, “chrysanthemum,” is a rather poetic amalgamation from Ancient Greek : χρυσός (chrysos), meaning “gold,” and ἄνθεμον (anthemon), meaning “flower.” It’s a fitting description, considering the vibrant hues many of its members display.

Description

The foliage of Chrysanthemum plants is characterized by alternate leaves, which are typically divided into leaflets. These leaves can be pinnatisect (feather-like), lobed, or serrate (toothed), though they are rarely entire (smooth-edged). They attach to stalks via hairy bases, giving them a slightly fuzzy texture.

The reproductive structure, the inflorescence , is usually a composite of several flower heads , though sometimes a single, solitary head is present. Each head is supported by a base covered in layers of phyllaries , which are essentially modified leaves. The ray florets, those petal-like structures that give the flower its distinctive appearance, are arranged in a single row and come in a spectrum of colors, including white, yellow, and red. The central disc florets are typically yellow. The pollen grains are quite small, measuring approximately 34 microns. The resulting fruit is a ribbed achene , a dry, single-seeded fruit characteristic of many plants in the Asteraceae family.

Etymology

As mentioned, the name “chrysanthemum” is a direct derivation from the Ancient Greek words “chrysos” (gold) and “anthemon” (flower). This nomenclature likely reflects the common golden-yellow color of many wild species and the historical significance attributed to the color gold.

Taxonomy

The formal description of the genus Chrysanthemum is credited to Carl Linnaeus in 1753, who initially identified fourteen species. However, the genus has a rather complicated taxonomic history. Over the years, many species, particularly those of horticultural importance, were separated into different genera. The florist’s chrysanthemums, for instance, were often placed in the genus Dendranthema. This taxonomic reshuffling led to considerable debate. A significant turning point occurred with a ruling by the International Botanical Congress in 1999, which re-established Chrysanthemum indicum as the type species for the genus Chrysanthemum. This decision effectively restored many of the economically significant florist’s chrysanthemums back into the genus Chrysanthemum.

Several genera that were once considered part of Chrysanthemum have since been established as distinct, including Argyranthemum , Glebionis , Leucanthemopsis , Leucanthemum , Rhodanthemum , and Tanacetum .

Ecology

Chrysanthemums typically begin their blooming cycle in early autumn, making them a prominent flower associated with the month of November in many regions. Their ecological role often involves attracting pollinators during a time when many other plants have finished their flowering cycle.

Cultivation

The cultivation of chrysanthemums dates back to ancient times, with evidence of their cultivation in China as early as the 15th century BCE . By 1630, over 500 distinct cultivars were documented. Today, the global number of cultivars is estimated to exceed 20,000, with China alone boasting around 7,000. In Chinese art and East Asian art, the chrysanthemum is revered as one of the “Four Gentlemen ,” alongside the plum blossom , the orchid , and bamboo . Its significance is particularly pronounced during the Double Ninth Festival .

The introduction of chrysanthemums to Japan occurred via China around the 5th century. Their cultivation gained significant traction during the Nara and Heian periods (early 8th to late 12th centuries) and experienced a surge in popularity during the Edo period (early 17th to late 19th century). This era saw the development of a remarkable diversity in flower shapes, colors, and varieties, alongside innovations in growing and shaping techniques. These Japanese cultivars were later exported to China, influencing local cultivation practices and aesthetic preferences. The Meiji period (late 19th to early 20th century) witnessed the creation of large-flowered varieties, known as the Ogiku style, some exceeding 20 centimeters in diameter, which continued to shape chrysanthemum trends. The imperial crest of Japan features a chrysanthemum, and the institution of the monarchy itself is sometimes referred to as the Chrysanthemum Throne . Autumn in Japan is marked by numerous festivals and exhibitions celebrating the blooming of these flowers. Chrysanthemum Day , or Kiku no Sekku, observed on the 9th day of the 9th month, is one of the ancient sacred festivals, with the imperial court hosting its first chrysanthemum show in 910.

Chrysanthemums made their way to American horticulture in 1798, with Colonel John Stevens importing a cultivar named ‘Dark Purple’ from England. This introduction was part of an effort to enhance the attractions at Elysian Fields in Hoboken, New Jersey .

Classification

For horticultural purposes, the National Chrysanthemum Society (USA) has established a classification system that divides all Chrysanthemum cultivars into 13 divisions, based primarily on their flower form. This system helps growers and enthusiasts categorize the vast array of available varieties.

Uses

Ornamental Uses

Modern cultivated chrysanthemums are bred for their striking appearance, often displaying more vibrant colors and more elaborate forms than their wild ancestors. Horticulturalists have developed numerous cultivars with multiple rows of ray florets in a wide array of colors, including white, purple, red, and various shades of yellow. The flower heads can present in diverse forms, from simple daisy-like shapes to complex decorative structures like pompons and buttons . The most significant hybrid, Chrysanthemum × morifolium (syn. C. × grandiflorum), is primarily derived from C. indicum but incorporates genetic material from other species.

As of 2017, over 140 Chrysanthemum cultivars have received the Royal Horticultural Society ’s Award of Garden Merit , a testament to their horticultural excellence.

In Japan, a unique tradition of chrysanthemum bonsai has been cultivated over centuries. These miniature trees, with flowers growing over dead wood to create the illusion of a tiny, blooming tree, are a testament to the intricate horticultural artistry associated with the plant.

Culinary Uses

In several East Asian countries, yellow or white chrysanthemum flowers, particularly from the species C. morifolium, are boiled to create a popular tea known as chrysanthemum tea (菊 花 茶, júhuā chá in Chinese). In Korea, a rice wine flavored with chrysanthemum flowers is called gukhwaju (국화주).

The leaves of chrysanthemum plants can be steamed or boiled and consumed as greens, especially in Chinese cuisine. The flowers themselves are sometimes added to dishes like mixian in broth or thick snakemeat soup (she gen) to enhance their aroma. They are also common ingredients in hot pot and stir-fries. In Japanese cuisine, small chrysanthemums are frequently used as a garnish for sashimi .

Insecticidal Uses

One of the most significant non-ornamental uses of chrysanthemums comes from the species Tanacetum cinerariifolium , formerly known as Chrysanthemum cinerariaefolium. This plant is a natural source of insecticide in the form of pyrethrins . These active compounds are extracted from the flowers, specifically from the achenes , and are processed into an oleoresin . This extract can be used as a suspension in water or oil, or as a powder. Pyrethrins are effective against the nervous systems of a wide range of insects and have the added benefit of deterring female mosquitoes from biting. While less toxic to mammals and birds than many synthetic insecticides, they are highly toxic to fish . A key advantage of pyrethrins is their biodegradability, as they decompose readily when exposed to light. Synthetic insecticides known as pyrethroids , such as permethrin , are derived from the chemical structure of natural pyrethrum. Despite their insecticidal properties, chrysanthemum leaves can still be susceptible to pests like leafminer flies . An industrial product derived from chrysanthemums used for insecticidal purposes is known as Persian powder .

Environmental Uses

The NASA Clean Air Study identified chrysanthemum plants as effective in reducing indoor air pollution .

In Culture

The symbolism of chrysanthemums varies significantly across different cultures and regions.

Europe

In some European countries, such as France, Belgium , Italy, Spain, Poland , Hungary , and Croatia , incurve chrysanthemums are specifically associated with death and are reserved for funerals or grave adornment. Other types of chrysanthemums may not carry this somber connotation.

East Asia

  • China: The chrysanthemum is the city flower of Beijing and Kaifeng . The tradition of chrysanthemum cultivation in China is ancient, with the Kaifeng Chrysanthemum Cultural Festival being the largest event of its kind in the country, held annually between October 18 and November 18. It is one of the “Four Gentlemen ” of Chinese art, symbolizing nobility and often favored by poets like Tao Qian . Chrysanthemums are also one of the four symbolic seasonal flowers. The city of Tongxiang near Hangzhou also hosts an annual chrysanthemum festival. Hundreds of Chinese poems feature chrysanthemums. The movie Curse of the Golden Flower takes its name from the flower. The term “Chrysanthemum Gate” (jú huā mén 菊花门) is taboo slang for the anus. An ancient city, Xiaolan Town of Zhongshan City, was named Ju-Xian, meaning “chrysanthemum city.” The flower is particularly significant during the Double Ninth Festival , symbolizing autumn and longevity. Historically, people drank chrysanthemum wine on the ninth day of the ninth lunar month to prolong their lives during the Han dynasty . In traditional Chinese medicine, Yejuhua and Juhua are listed in the Pharmacopoeia of the People’s Republic of China for treating various ailments.

  • Japan: Chrysanthemums arrived in Japan from China around the 5th century. They became a prominent theme in waka (Japanese traditional poetry) by the 10th century. In the 12th century, during the Kamakura period , the retired Emperor Go-Toba adopted the chrysanthemum as the mon (family crest) of the Imperial family , solidifying its status as a symbol of autumn. The Edo period saw a flourishing of chrysanthemum cultivation, with numerous cultivars developed and exhibitions held. The Meiji period further elevated the chrysanthemum’s importance as a symbol of the Imperial family, leading to the development of large-flowered Ogiku varieties. Today, chrysanthemum exhibitions are held in prominent locations like Shinjuku Gyo-en , Meiji Shrine , and Yasukuni Shrine in Tokyo . Culinary-grade chrysanthemums are used in food presentation, and the flower remains a popular motif in traditional Japanese arts , including porcelain , lacquerware , and kimono . Chrysanthemum growing is a popular hobby, with numerous contests held. The city of Nihonmatsu is known for its “Nihonmatsu Chrysanthemum Dolls Exhibition.” The chrysanthemum is a profound symbol of the Emperor and the Imperial family . The “chrysanthemum crest” (kikukamonshō) is a direct link to the Emperor. The imperial crest of Japan is a 16-petal chrysanthemum design. The Emperor’s throne is known as the Chrysanthemum Throne . The Supreme Order of the Chrysanthemum is a high Japanese honor. In Imperial Japan, small arms were stamped with the imperial chrysanthemum, signifying they were the personal property of the emperor. The Nagoya Castle Chrysanthemum Competition is a significant annual event.

  • Korea: Chrysanthemums are featured on inlaid Goreyo ware and Buncheong wares . Korean potters, like Kim Se-yong, have created exquisite celadon wares with intricately painted chrysanthemum petals. Laying white chrysanthemums at funerals has been a custom since the early 20th century, a practice adopted to maintain a tradition of using white for mourning after Western culture introduced black as the prevalent funeral color. The Masan Gagopa Chrysanthemum Festival is a notable event.

West Asia

  • Iran: In Iran, chrysanthemums are associated with Ashi Vanghuhi, a Zoroastrian spiritual being representing blessings.

Oceania

  • Australia: On Mother’s Day (which falls in May when chrysanthemums are in season), Australians traditionally wear a white chrysanthemum to honor their mothers, and the flowers are common Mother’s Day gifts.

North America
