This is a direct adoption of the Japanese word "Kuzu."
Especially in America, it is sometimes called "the vine that ate the South."

About Kudzu Flower Meanings
The flower meanings of kudzu are derived from its vigorous growth and its history of being celebrated in waka poetry.
1. "Inner Strength"
Kudzu is a plant that spreads along the ground and intertwines with other plants as it grows. It possesses exceptionally strong vitality.
This robust appearance, symbolizing an inner strength that belies its exterior, gave rise to the flower meaning of "inner strength."
2. "Vitality"
The flower meaning "vitality" was attributed to kudzu due to its vigorous growth, extending its vines rapidly while basking in the sun from summer to autumn.
The sight of life-affirming kudzu is sure to energize anyone who sees it.
3. "Bonds of Love"
This flower meaning originated from the appearance of its vines intertwining with other plants, which seemed to symbolize strong bonds and deep affection between a man and a woman.
Since ancient times, it has been widely featured in love poems in waka collections such as the "Manyoshu."
What is the History of Kudzu?
Kudzu is a plant deeply intertwined with Japanese history and culture due to its powerful vitality and diverse uses. It has been an indispensable part of literature and crafts, as well as a food and medicinal source.
Utilized since the Jomon period!
The history of kudzu is very old, dating back to the Jomon period.
From archaeological sites of that time, baskets woven from kudzu vines and fibers for clothing have been discovered, indicating that kudzu was an essential resource for human life since ancient times.
Due to its strong fibrous nature, kudzu was widely used as material for ropes, nets, and woven fabrics.

Appears in "Manyoshu" during the Nara period
Kudzu appears in the "Manyoshu" from the Nara period as one of the "Seven Autumn Flowers" composed by Yamabe no Akahito.
The original text is "芽之花 乎花葛花 瞿麦之花 姫部志 又藤袴 朝皃之花."
It means: Hagi (bush clover) flowers, Obana (pampas grass) flowers, Kudzu flowers, Nadeshiko (pink) flowers, Ominaeshi (patrinia) flowers, and Fujibakama (thoroughwort) flowers, as well as Asagao (morning glory) flowers.
The "葛花" in Obana-Katsuhana refers to the Kudzu flower.

Kudzu as Food
The starch extracted from kudzu roots has long been incorporated into Japanese food culture as "kuzuko" (kudzu starch).
It was particularly prized as an ingredient in traditional Japanese sweets for its translucent appearance and refined texture.
Dishes and sweets made with kuzuko, such as kuzumochi and kuzuan (kudzu starch sauce), are among Japan's representative food items.
Furthermore, during famines, kudzu roots served as a valuable food source, saving people's lives.

(Reference: Yamagata University "Katemono = Famine Food")
Kudzu as Medicine
Kudzu also has a history of its roots being used as a traditional Chinese medicine.
In Japan, dried kudzu roots, known as "Kakkon," have a history of being used as medicine.
In particular, "Kakkonto" (Kudzu Root Decoction), used at the onset of a cold, is a well-known traditional Chinese medicine made from kudzu roots.
Kakkonto is believed to warm the body, promote sweating, and alleviate early cold symptoms and stiffness in the shoulders and neck, and is still widely used today.

Kudzu remaining in surnames and place names
Kudzu also features prominently in many Japanese place names and surnames.
Place names like "Katsuragi" and "Kassai" are said to originate from areas where kudzu once grew in abundance.
Kudzu, by deeply influencing people's lives, has left its mark on modern times through place names and surnames.
(Reference: Katsuragi City "Katsuragi / Katsuragi City")
Kudzu Abroad
While kudzu has been beloved in Japan since ancient times, it has had an unexpected history overseas.
A huge hit at the World's Fair in America!
Kudzu made its way to America at the Philadelphia World's Fair in 1876.
Introduced as an exhibit in the Japanese pavilion, kudzu gained popularity as an ornamental plant due to its beautiful flowers and fast-growing nature.
(Reference: ALABAMA A&M and AUBURN UNIVERSITIES "The History and Use of Kudzu in the Southeastern United States")
Used for soil conservation in the American South
In the 1930s, kudzu's strong vitality garnered attention for its ability to prevent soil erosion.
It was recommended to farmers in the American South for planting and was initially highly valued.
(Reference: ALABAMA A&M and AUBURN UNIVERSITIES "The History and Use of Kudzu in the Southeastern United States")
And then it became an invasive alien species…
However, the warm climate of the American South provided an optimal growing environment for kudzu.
Its prolific growth became uncontrollable, covering forests, houses, and utility poles.
Consequently, it earned the nickname "the vine that ate the South" and is now targeted for eradication as an invasive alien species.
(Reference: The Nature Conservancy "Kudzu: The Invasive Vine that Ate the South")
Kudzu's Use in Traditional Medicine
Kudzu, from its roots to its flowers, has been widely utilized in people's lives.
Everyone knows the traditional medicine "Kakkonto"
Dried kudzu root, known as "Kakkon," has been used in traditional medicine since ancient times.
It is particularly famous as the main ingredient of "Kakkonto" (Kudzu Root Decoction), which is said to be effective at the onset of a cold.
Not just the roots, but also the flowers are used as medicine
Kudzu is used not only for its roots but also for its flowers.
