Question: Pueraria and Saponaria, are native to which mutual country?

full_context: Document 1: Pinellia: Pinellia is a genus of plants in the family Araceae native to East Asia (China, Korea, Japan). Its species are commonly called green dragons due to the color and shape of the inflorescence, which possesses a green, hooded spathe from which protrudes a long, tongue-like extension of the spadix. The leaves vary greatly in shape among different species, from simple and cordate to compound with three to many leaflets. "Pinellia" reproduces rapidly from seed and many species also produce bulbils on the leaves. Both characteristics have allowed some species to become weedy in temperate areas outside their native range, notably "Pinellia ternata" in eastern North America.
Document 2: Saponarin: Saponarin is a flavone glucoside. It is found in "Saponaria officinalis" and in "Strongylodon macrobotrys" where it imparts the characteristic jade color to the flower. This coloration has been shown to be an example of copigmentation, a result of the presence of malvin (an anthocyanin) and saponarin in the ratio 1:9. Under the alkaline conditions (pH 7.9) found in the sap of the epidermal cells, this combination produced a blue-green pigmentation; the pH of the colorless inner floral tissue was found to be lower, at pH 5.6. Experiments showed that saponarin produced a strong yellow colouring in slightly alkaline conditions, resulting in the greenish tone of the flower. It is also found in passion flowers ("Passiflora sp.").
Document 3: Hydrangea: Hydrangea ( ; common names hydrangea or hortensia) is a genus of 70–75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Document 4: Saponaria ocymoides: Saponaria ocymoides (rock soapwort or tumbling Ted) is a species of semi-evergreen perennial flowering plant belonging to the family Caryophyllaceae, native to south western and southern central Europe.
Document 5: Sapindus saponaria: Sapindus saponaria is a small to medium-sized deciduous tree native to the Americas. Common names include wingleaf soapberry, western soapberry, jaboncillo, sulluku and mānele (Hawaiian). Its genus name, ""Sapindus"", comes from the Latin, meaning Indian soap, and its specific epithet means "soapy."
Document 6: Physochlaina: Physochlaina is a small genus of herbaceous perennial plants belonging to the nightshade family, Solanaceae, found principally in the north-western provinces of China (and regions adjoining these in the Himalaya and Central Asia) although one species occurs in Western Asia, while another is found as far east as those regions of Siberia abutting the eastern borders of Mongolia and also not only in Mongolia itself, but also the Chinese autonomous region of Inner Mongolia. The genus is a valuable one, since its species are not only of considerable medicinal value, being rich in tropane alkaloids, but also of ornamental value, three species having been grown for the purpose, although hitherto infrequently outside botanical gardens. Furthermore, the genus contains a species ("P. physaloides" - recorded in older literature under the synonyms "Hyoscyamus physaloides" and "Scopolia physaloides") formerly used as an entheogen in Siberia.
Document 7: Gynura aurantiaca: Gynura aurantiaca, called purple passion or velvet plant is a species of plants in the chrysanthemum family It is native to Southeast Asia but grown in many other places as a house plant. In warm regions, it is frequently grown in outdoor on patios and in gardens rather than inside buildings, and hence it has escaped into the wild in Africa, Australia, South America, Mesoamerica, Florida, and a few other places.
Document 8: Saponaria: Saponaria is a genus of flowering plants in the pink family, Caryophyllaceae. They are native to Europe and Asia, and are commonly known as soapworts.
Document 9: Sagina: Sagina (like "Colobanthus" called "pearlworts") is a genus of 20–30 species of flowering plants in the pink or carnation family, Caryophyllaceae. These are flowering herbs native to temperate regions of the Northern Hemisphere extending south to tropical mountain areas at high altitudes, reaching just south of the equator in Africa. They are small annual or perennial herbaceous plants, growing to 5–15 cm. The leaves are opposite, often in tight whorl-like clusters, simple linear, typically 5–20 mm long. The flowers are solitary or in small cymes, with four or five green sepals and an equal number of white petals; the petal size relative to the sepal size is useful in species identification. The fruit is a small capsule containing several seeds.
Document 10: Quillaja: Quillaja is a genus of flowering plants, the only genus in the family Quillajaceae with two or three known species. It was once thought to be in the rose family, Rosaceae, but recent research shows it belongs in its own family. The inner bark of the soap bark tree ("Q. saponaria") contains saponin, which is a natural soap. Members of this genus are trees that grow to about 25 m .
Document 11: Gentiana saponaria: Gentiana saponaria (soapwort gentian or harvestbells) is a 1 - tall flowering plant in the Gentianaceae family. It is native to eastern North America south of the Great Lakes, from Wisconsin to New York, and south to Texas and Florida. Similar to the "Bottle Gentians" like "Gentiana clausa" and "Gentiana andrewsii", it has paired, lanceolate leaves on unbranched stalks, blue or purple blooms, and a stout taproot. It is rare in its range, usually found in undisturbed sandy soils. The flowers are pollinated by bumblebees.
Document 12: Pollia japonica: Pollia japonica, known as East Asian pollia in English, Yabumyoga(ヤブミョウガ ) in Japanese, and dùruò(杜若 ) in Chinese, is a perennial flower native to East Asia. Its niche is forests 0–1200 m. It is native in Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, and Sichuan Provinces of China. Also found in Taiwan, Japan, and Korea.
Document 13: Pueraria: Pueraria is a genus of 15–20 species of plants native to Asia. "Pueraria" flower is used in traditional Chinese medicine to reduce reactions to alcohol consumption, and is undergoing scientific study for that use.
Document 14: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 15: Kudzu: Kudzu ( , also called Japanese arrowroot) is a group of plants in the genus "Pueraria", in the pea family Fabaceae, subfamily Faboideae. They are climbing, coiling, and trailing perennial vines native to much of eastern Asia, Southeast Asia, and some Pacific islands. The name is derived from the Japanese name for the plants, kuzu (クズ or 葛) , which was written "kudzu" in historical romanizations. Where these plants are naturalized, they can be invasive and are considered noxious weeds. The plant climbs over trees or shrubs and grows so rapidly that it kills them by heavy shading. The plant is edible, but often sprayed with herbicides.
