Many different cultivars of this maple have been selected and they are grown worldwide for their large variety of attractive forms, leaf shapes, and spectacular colors. Acer palmatum

198-508: A centrally planned industrial economy. South Korea is a multi-party state with a capitalist market economy , alongside membership in the Organisation for Economic Co-operation and Development and the Group of Twenty . The two states have greatly diverged both culturally and economically since their partition, though they still share a common traditional culture and pre-Cold War history. Since

Later Silla fell apart in the late 9th century, giving way to the tumultuous Later Three Kingdoms period (892–935), and Balhae was destroyed by the Khitans in 926. Goryeo unified the Later Three Kingdoms and received the last crown prince and much of the ruling class of Balhae, thus bringing about

396-429: A V shape. Any other buds are rubbed away. Removing the vertical stem completes the individual V-shaped espalier. By placing many similarly trained trees in a line two feet apart with their branches trained to the same plane, a Belgian fence is created. The Belgian fence is an intermediary form that can then be used to train onward to many other forms of espalier, including: Step-over, where the branches are lowered down to

The prevailing philosophy of the Joseon dynasty was Neo-Confucianism , which

693-518: A hedge, but instead methodically shaped by carefully choosing individual branches to remove. They can also be pruned just to maintain a smaller size to suit a particular location. Acer palmatum can also be used as espalier . Over 1,000 cultivars have been chosen for particular characteristics, which are propagated by asexual reproduction most often by grafting , but some cultivars can also be propagated by budding , cuttings , tissue culture , or layering . Some cultivars are not in cultivation in

792-465: A new renaissance of the Joseon dynasty during the 18th century. In the 19th century, the royal in-law families gained control of the government, leading to mass corruption and weakening of the state, with severe poverty and peasant rebellions spreading throughout the country. Furthermore, the Joseon government adopted a strict isolationist policy, earning the nickname "the hermit kingdom ", but ultimately failed to protect itself against imperialism and

891-540: A popular choice for bonsai enthusiasts and have long been a subject in art. Numerous cultivars are popular in Europe and North America , with red-leafed favored, followed by cascading green shrubs with deeply dissected leaves. Acer palmatum includes thousands of named cultivars with a variety of forms, colors, leaf types, sizes, and preferred growing conditions. Heights of mature specimens range from 0.5 to 25 m (1 ⁄ 2 to 82 ft), depending on type. Preparations from

The war ended with an armistice agreement at approximately

1089-452: A unification of the two successor nations of Goguryeo . Goryeo was founded in 918 and replaced Silla as the ruling dynasty of Korea. Goryeo's land was at first what is now South Korea and about 1/3 of North Korea, but later on managed to recover most of the Korean peninsula. Momentarily, Goryeo advanced to parts of Jiandao while conquering the Jurchens , but returned the territories due to

1188-602: A wall constructed of suitable material. Masonry walls are ideal for placing U-bolts , eye bolts, or eye screws, anchored with either plastic plugs or expandable lead shields, directly into the mortar joints. Wooden walls may be better fitted with galvanized nipples, using turnbuckles for adjustment of the wire tautness. Suitable, established and healthy plants, three to four feet tall and perhaps in three-gallon containers, are available from most nurseries . Some may even have trellises already installed. These plants could also be good candidates for espalier treatment if their form

1287-620: Is deciduous , with the growth habit of a shrub or small tree reaching heights of 6 to 10 m (20 to 33 ft), rarely 16 m (52 ft), reaching a mature width of 4.5 to 10 m (15 to 33 ft), often growing as an understory plant in shady woodlands . It may have multiple trunks joining close to the ground. In habit , its canopy often takes on a dome -like form, especially when mature. The leaves are 4–12 cm ( 1 + 1 ⁄ 2 – 4 + 3 ⁄ 4  in) long and wide, palmately lobed with five, seven, or nine acutely pointed lobes. The flowers are produced in small cymes ,

South Korea has been renowned for its globally influential pop culture, particularly in music ( K-pop ) and cinema , a phenomenon referred to as

1584-445: Is a modern usage to distinguish the ancient Joseon from the later dynasty. It is unclear whether Joseon was a transcription of a native Korean name ( OC * T[r]awser , MC Trjewsjen ) or a partial translation into Chinese of the Korean capital Asadal ( 아사달 ), whose meaning has been reconstructed as "Morning Land" or "Mountain". The Korean Academy claimed ancient hominid fossils originating from about 100,000 BCE in

1683-587: Is also sometimes used to describe other species, usually within the series Palmata , that are similar to A. palmatum and native to China, Korea or Japan, including: Given that these maples are phenotypically variable within each species, and may hybridise with one another, distinguishing between them may be a matter of gradient speciation . In commercial propagation, A. palmatum is often used as rootstock for many of these other species. Korea Korea ( Korean : 한국 , romanized :  Hanguk in South Korea, or 조선 , Chosŏn in North Korea)

1782-436: Is limited. In a temperate climate , espaliers may be trained next to a wall that can reflect more sunlight and retain heat overnight or oriented so that they absorb maximum sunlight by training them parallel to the equator. These two strategies allow the season to be extended so that fruit has more time to mature. A restricted form of training consists of a central stem and a number of paired horizontal branches all trained in

1881-583: Is not a constraint, no pruning is necessary except to remove any dead branches. Trees naturally self-prune foliage that doesn't receive enough light, such as internal branches which are overly shaded by its own canopy. Some growers prefer to shape their trees artistically or to thin out interior branches to better expose the graceful main branches. The form of the tree, especially without leaves in winter, can be of great interest and can be pruned to highlight this feature. Trees heal readily after pruning without needing aftercare. This species should not be pruned like

1980-467: Is now believed to have been the last kingdom to develop. By the 2nd century, Silla existed as a large state in the southeast, occupying and influencing its neighbouring city-states. In 562, Silla annexed the Gaya confederacy , which was located between Baekje and Silla. The Three Kingdoms of Korea often warred with each other and Silla was often dominated by Baekje and Goguryeo. Silla was the smallest and weakest of

2079-425: Is similar to the intended design, as they frequently have already been pruned into a flattened overall plant shape. All that is required for such specimens is transplanting . Unpruned plants benefit from being allowed to become well established following transplant, before pruning them gradually into their flattened profile and training them as designed. Any major pruning needed is generally accomplished either while

Korea was transliterated as Cauli in The Travels of Marco Polo , of

2277-419: Is typical for the species, but are more interesting than the relatively mundane species. Cultivars come in a large variety of forms including upright, broom, vase, umbrella, weeping, cascading, dwarf, shrub, and ground cover. Most cultivars are artificially selected from seedlings of open-pollinated plants, purposeful breeding is not common, and less often from grafts of witch's brooms . In Japan, iromomiji

2376-626: Is used as an accent tree in Japanese gardens, providing gentle shade next to the house in the summer and beautiful colors in autumn. Many cultivars have characteristics that come into prominence during different seasons, including the color of new or mature leaves, extraordinary autumn color, color and shape of samaras, or even bark that becomes more brightly colored during the winter. Some cultivars can scarcely be distinguished from others unless labeled. In some cases, identical cultivars go by different names, while in other cases, different cultivars may be given

2475-558: The Chinese 高麗 ( MC : Kawlej , mod. Gāolì ). This was the Hanja for the Korean kingdom of Goryeo ( Korean :  고려 ; MR :  Koryŏ ), which ruled most of the Korean peninsula during the 12th century.

In 668 AD, Silla conquered Baekje and Goguryeo with the aid of the Tang dynasty , forming Unified Silla ; Balhae succeeded Goguryeo in the north. In the late 9th century, Unified Silla collapsed into three states, beginning the Later Three Kingdoms period. In 918, Goguryeo

2772-609: The Khitans and the Mongols . Goryeo had a hostile relationship with the Khitans, because the Khitan Empire had destroyed Balhae , also a successor state of Goguryeo. In 993, the Khitans, who had established the Liao dynasty in 907, invaded Goryeo , demanding that it make amity with them. Goryeo sent the diplomat Sŏ Hŭi to negotiate, who successfully persuaded the Khitans to let Goryeo expand to

During the Goryeo–Khitan War , the Khitan Empire invaded Korea twice more in 1009 and 1018 , but was defeated. After defeating the Khitan Empire, which was the most powerful empire of its time, Goryeo experienced a golden age that lasted a century, during which the Tripitaka Koreana

5841-694: The branches and leaves are used as a treatment in traditional Chinese medicine . In their natural habitat, they grow in the understory; most cultivars prefer part shade, especially in hotter climates, but they will also grow in heavy shade. Some cultivars will tolerate full sun, more so at higher latitudes and less at lower latitudes; red, purple-red, black-red, bronze, and some dark green cultivars are generally more full sun tolerant. Variegated white, cream, yellow, yellow-orange, or light green cultivars mostly require shade protection. Almost all are adaptable and blend well with companion plants . The trees are particularly suitable for borders and ornamental paths because

Espalier plants on solid walls are usually installed 15–30 cm (6–12 in) from the base of that wall, to allow space below ground for roots to grow in all directions as well as space above ground for good air circulation and pest control . Supports for wire guides, which are generally necessary to train an espalier into a design, are installed first, directly into

6435-420: The following year. Beginning in the 6th century, Silla 's power gradually extended across the Korean Peninsula. Silla first annexed the adjacent Gaya confederacy in 562. By the 640s, Silla formed an alliance with the Tang dynasty of China to conquer Baekje and later Goguryeo . After conquering Baekje and Goguryeo, Silla repulsed Tang China from the Korean peninsula in 676. Even though Silla unified most of

Unnecessary buds are removed by rubbing them away with a thumb. In autumn, the side branches are lowered and tied to the wires completing the level. The following year another level is created. Examples of species for espalier include: Espalier design often uses traditional formal patterns developed over hundreds of years, but can also employ more modern informal designs. A stunted or deformed plant, or one that already has interesting or unique characteristics, might be just right for an informal espalier. Common formal patterns include

6633-442: The harsh climate and difficulties in defending them. The name "Goryeo" (高麗) is a short form of " Goguryeo " (高句麗) and was first used during the time of King Jangsu . Goryeo regarded itself as the successor of Goguryeo, hence its name and efforts to recover the former territories of Goguryeo.

In the final years of the 19th century, Japan forced Joseon to open up and Joseon experienced turmoil such as the Gapsin Coup , Donghak Peasant Revolution , and the assassination of Empress Myeongseong . In 1895, Japan defeated China in the First Sino-Japanese War and China lost suzerainty over Korea and Korea

7029-441: The lava at a stone city site in Korea. Fluorescent and high-magnetic analyses indicate the volcanic fossils may be from as early as 300,000 BCE. The best preserved Korean pottery goes back to the paleolithic times around 10,000 BCE and the Neolithic period begins around 6000 BCE. Beginning around 300 BC, the Japonic -speaking Yayoi people from the Korean Peninsula entered the Japanese islands and displaced or intermingled with

7128-640: The most recent North Korean census suggest that 240,000 to 420,000 people died as a result of the 1990s famine and that there were 600,000 to 850,000 unnatural deaths in North Korea from 1993 to 2008. In South Korea, as guerrilla activities expanded, the South Korean government used strong measures against peasants, such as forcefully moving their families from guerrilla areas. According to one estimate, these measures resulted in 36,000 people killed, 11,000 people wounded, and 432,000 people displaced. The Korean War broke out when Soviet-backed North Korea invaded South Korea, though neither side gained much territory as

7227-475: The north, parts of Inner Mongolia to the west, parts of Russia to the east, and the Seoul region to the south. Goguryeo experienced a golden age under Gwanggaeto the Great and his son Jangsu , who both subdued Baekje and Silla during their times, achieving a brief unification of the Three Kingdoms of Korea and becoming the most dominant power on the Korean Peninsula. In addition to contesting for control of

7326-529: The northern Korean peninsula. Balhae was called the "Prosperous Country in the East". Later Silla carried on the maritime prowess of Baekje , which acted like the Phoenicia of medieval East Asia , and during the 8th and 9th centuries dominated the seas of East Asia and the trade between China, Korea and Japan, most notably during the time of Jang Bogo ; in addition, Silla people made overseas communities in China on

7425-454: The open space and to decorate solid walls by planting flattened trees near them. Vineyards have used the technique in the training of grapes for hundreds or perhaps even thousands of years. A Belgian fence is created by cutting back an unbranched, slender tree to between 40 and 45 centimetres (15 and 18 in) above the ground. The topmost three buds are allowed to form; one in the middle is trained vertically while two others are trained into

7524-620: The original Jōmon inhabitants. The linguistic homeland of Proto- Koreans is located somewhere in Southern Siberia / Manchuria, such as the Liao river area or the Amur region. Proto-Koreans arrived in the southern part of the Korean Peninsula at around 300 BC, replacing and assimilating Japonic-speakers and likely causing the Yayoi migration. According to Korean legend, Dangun , a descendant of Heaven , established Gojoseon in 2333 BCE. In 108 BCE,

7623-436: The outbreak of the Korean War in 1950, which came to involve U.S.-led United Nations and communist Chinese forces. The war ended in stalemate in 1953, but without a peace treaty. A demilitarized zone was created between the countries, approximating the original partition. This status contributes to the high tensions that divide the peninsula, and both states claim to be the sole legitimate government of Korea. South Korea

7722-424: The parent. Many of these are sold under the same name as the cultivars, or even propagated by grafting, so there is often much ambiguity in distinguishing them. In particular, a number of dark-red Acer palmatum are sold with the names ‘Atropurpureum’ and ‘Bloodgood’. Many different cultivars with delicate lace-like foliage are sold under names such as ‘Dissectum’, ‘Filigree’ and ‘Laceleaf’. The term "Japanese maple"

7821-518: The root systems are compact and not invasive. Many varieties of Acer palmatum are successfully grown in containers. Trees are prone to die during periods of drought and prefer consistent water conditions; more established trees are less prone to drought. Moderate to well-drained soil is essential as they will not survive in poorly drained waterlogged soil. Trees do not require heavy fertilization and should only be very lightly fertilized. Japanese maples are best to grow in hardiness zones 5–8. If space

7920-496: The same name. A selection of notable or popular cultivars, with brief notes about characteristics that apply during at least one season, includes the following. agm indicates the cultivar has gained the Royal Horticultural Society's Award of Garden Merit . In addition to the cultivars described above, a number of cultivar groups have been naturally selected over time to such an extent that seedlings often resemble

8019-453: The same parent tree typically showing differences in such traits as leaf size, shape, and color. The overall form of the tree can vary from upright to weeping. Three subspecies are recognised: Acer palmatum has been cultivated in Japan for centuries and in temperate areas around the world since the 1800s. The first specimen of the tree reached Britain in 1821. When Swedish doctor-botanist Carl Peter Thunberg traveled in Japan late in

8118-474: The same plane. The most important advantage is that of being able to increase the growth of a branch by training it vertically. Later, one can decrease growth while increasing fruit production by training it horizontally. The word espalier is French, coming from the Italian spalliera , meaning "something to rest the shoulder ( spalla ) against." During the 17th century, the word initially referred only to

8217-455: The second year. Multiple levels of horizontal branching can be trained in this way. Certain types of trees adapt better to espalier than others, but almost any woody plant can be trained to grow along a flat plane by removing growth outside that plane. Horizontal T training of an apple or pear tree is a good example of the ideal species for espalier. In the spring, the tree is pruned to the lowest wire perhaps 40–45 cm (15–18 in) above

8316-473: The south, which fought the Korean War from 1950 to 1953. The region is bordered by China to the north and Russia to the northeast, across the Amnok (Yalu) and Duman (Tumen) rivers, and is separated from Japan to the southeast by the Korea Strait . Known human habitation of the Korean peninsula dates to 40,000 BC. The kingdom of Gojoseon , which according to tradition was founded in 2333 BC, fell to

8415-590: The southern half of the Korean Peninsula , maintaining the former Samhan territories, while Goguryeo controlled the northern half of the Korean Peninsula, Manchuria and the Liaodong Peninsula , uniting Buyeo , Okjeo , Dongye , and other states in the former Gojoseon territories. Goguryeo was a highly militaristic state, and a large empire in East Asia, reaching its zenith in the 5th century when its territories expanded to encompass most of Manchuria to

8514-551: The three, but it used cunning diplomatic means to make opportunistic pacts and alliances with the more powerful Korean kingdoms, and eventually Tang China, to its great advantage. In 660, King Muyeol ordered his armies to attack Baekje . General Kim Yu-shin , aided by Tang forces, conquered Baekje after defeating General Gyebaek at the Battle of Hwangsanbeol . In 661, Silla and Tang attacked Goguryeo but were repelled. King Munmu , son of Muyeol and nephew of General Kim Yu-shin, launched another campaign in 667 and Goguryeo fell in

8613-499: The title khan used by the nomads of Manchuria and Central Asia . In North Korea, Korea as a whole is referred to as Joseon ( 조선 ; lit.  [land of the] Morning Calm, [tɕosʰʌn] ). Joseon is the modern Korean pronunciation of the Hanja 朝鮮 , which is also the basis of the word for Korea as a whole in Japan ( 朝鮮 , Chōsen ), China ( 朝鮮 ; Cháoxiǎn ), and Vietnam ( Triều Tiên ). "Great Joseon "

8712-482: The western Korean peninsula (including the modern provinces of Gyeonggi , Chungcheong , and Jeolla , as well as parts of Hwanghae and Gangwon ) to a centralised government; during the expansion of its territory, Baekje acquired Chinese culture and technology through maritime contacts with the Southern Dynasties . Baekje was a great maritime power; its nautical skill, which made it the Phoenicia of East Asia,

8811-517: Was a continuation of Goguryeo (Koguryŏ) the northernmost of the Three Kingdoms of Korea , which was officially known as Goryeo beginning in the 5th century. The original name was a combination of the adjectives ("high, lofty") with the name of a local Yemaek tribe, whose original name is thought to have been either " Guru" ( 溝樓 , 'Walled City', inferred from some toponyms in Chinese historical documents) or " Gauri" ( 가우리 , 'Center'). With expanding British and American trade following

8910-498: Was assassinated by Japanese agents. In 1897, the Joseon dynasty proclaimed the Korean Empire (1897–1910). King Gojong became emperor. During this brief period, Korea had some success in modernising the military, economy, real property laws, education system, and various industries. Russia , Japan, France , and the United States all invested in the country and sought to influence it politically. The Russians were pushed out of

9009-446: Was completed, and there were great developments in printing and publishing, promoting learning and dispersing knowledge on philosophy, literature, religion, and science; by 1100, there were 12 universities that produced famous scholars and scientists. Goryeo was invaded by the Mongols in seven major campaigns from the 1230s until the 1270s, but was never conquered. Exhausted after decades of fighting, Goryeo sent its crown prince to

9108-602: Was epitomised by the seonbi class, scholars who passed up positions of wealth and power to lead lives of study and integrity. Joseon was a nominal tributary state of China but exercised full sovereignty, and maintained the highest position among China's tributary states, which also included countries such as the Ryukyu Kingdom , Vietnam, Burma, Brunei, Laos, Thailand, and the Philippines, among others. In addition, Joseon received tribute from Jurchens and Japanese until

9207-570: Was forced to open its borders, beginning an era leading into Japanese imperial rule . Beginning in 1871, Japan began to exert more influence in Korea, forcing it out of China's traditional sphere of influence. As a result of the First Sino-Japanese War (1894–95), the Qing dynasty had to give up such a position according to Article 1 of the Treaty of Shimonoseki , which was concluded between China and Japan in 1895. That same year, Empress Myeongseong of Korea

9306-433: Was instrumental in the dissemination of Buddhism throughout East Asia and continental culture to Japan. Historic evidence suggests that Japanese culture, art, and language were influenced by the kingdom of Baekje and Korea itself; Baekje also played an important role in transmitting advanced Chinese culture to the Japanese archipelago. Baekje was once a great military power on the Korean Peninsula, most notably in

9405-591: Was placed under further Japanese influence. In 1897, the centuries old Joseon was replaced by the Korean Empire with the Joseon's last king, Gojong , becoming the Emperor of the Korean Empire. Japan's further victory in the 1904–1905 Russo-Japanese War , expelled Russian influence in Korea and Manchuria. In 1905, the Korean Empire became a protectorate of the Empire of Japan . In 1910, the Empire of Japan officially annexed

9504-407: Was resurrected as Goryeo , which achieved what has been called a "true national unification" by Korean historians, as it unified both the Later Three Kingdoms and the ruling class of Balhae after its fall. Goryeo, whose name developed into the modern exonym "Korea", was highly cultured and saw the invention of the first metal movable type . During the 13th century, Goryeo became a vassal state of

9603-941: Was signed by Lee Wan-Yong , who was given the General Power of Attorney by the Emperor. However, the Emperor is said to have not actually ratified the treaty according to Yi Tae-jin. There is a long dispute whether this treaty was legal or illegal due to its signing under duress, threat of force and bribes. Korean resistance to the brutal Japanese occupation was manifested in the nonviolent March First Movement of 1919, during which 7,000 demonstrators were killed by Japanese police and military. The Korean liberation movement also spread to neighbouring Manchuria and Siberia . Over five million Koreans were conscripted for labour beginning in 1939, and tens of thousands of men were forced into Japan's military. Nearly 400,000 Korean labourers died. Approximately 200,000 girls and women, mostly from China and Korea, were forced into sexual slavery for

9702-456: Was the name of the kingdom ruled by the Joseon dynasty from 1392 until their declaration of the short-lived Great Korean Empire in 1897. King Taejo had named them for the earlier Gojoseon ( 고조선 ), who ruled northern Korea from its legendary prehistory until their conquest in 108 BCE by China's Han Empire . The Go- in Gojoseon is the Hanja word 古 and simply means "ancient" or "old"; it

9801-507: Was thrown into chaos and weakened by a succession struggle among his sons and younger brother, with his eldest son defecting to Tang and his younger brother defecting to Silla. The Tang-Silla alliance conquered Goguryeo in 668. After the collapse of Goguryeo, Tang and Silla ended their alliance and fought over control of the Korean Peninsula. Silla succeeded in gaining control over most of the Korean Peninsula, while Tang gained control over Goguryeo's northern territories. However, 30 years after
