Shinjuku Gyoen
is a large park and garden in Shinjuku and Shibuya, Tokyo, Japan. It was originally a residence of the Naitō family in the Edo period. Afterward, it became a garden under the management of Japan Imperial Household Agency. It is now a national park under the jurisdiction of the Ministry of the Environment. History The ''shōgun'' bequeathed this land to Lord Naitō (''daimyō'') of Tsuruga in the Edo period who completed a garden here in 1772. After the Meiji Restoration the house and its grounds were converted into an experimental agricultural centre. It then became a botanical garden before becoming an imperial garden in 1879. The current configuration of the garden was completed in 1906. Most of the garden was destroyed by air raids in 1945, during the later stages of World War II. The garden was rebuilt after the war. The jurisdiction over the Imperial Palace Outer Garden and the Kyoto imperial garden was transferred to the Ministry of Health and Welfare (now the Min ...

Muromachi Period
The is a division of Japanese history running from approximately 1336 to 1573. The period marks the governance of the Muromachi or Ashikaga shogunate (''Muromachi bakufu'' or ''Ashikaga bakufu''), which was officially established in 1338 by the first Muromachi ''shōgun'', Ashikaga Takauji, two years after the brief Kenmu Restoration (1333–1336) of imperial rule was brought to a close. The period ended in 1573 when the 15th and last shogun of this line, Ashikaga Yoshiaki, was driven out of the capital in Kyoto by Oda Nobunaga. From a cultural perspective, the period can be divided into the Kitayama and Higashiyama cultures (later 15th – early 16th centuries). The early years from 1336 to 1392 of the Muromachi period are known as the '' Nanboku-chō'' or Northern and Southern Court period. This period is marked by the continued resistance of the supporters of Emperor Go-Daigo, the emperor behind the Kenmu Restoration. The Sengoku period or Warring States period, which begi ...

Kyoto
Kyoto (; Japanese: , ''Kyōto'' ), officially , is the capital city of Kyoto Prefecture in Japan. Located in the Kansai region on the island of Honshu, Kyoto forms a part of the Keihanshin metropolitan area along with Osaka and Kobe. , the city had a population of 1.46 million. The city is the cultural anchor of a substantially larger metropolitan area known as Greater Kyoto, a metropolitan statistical area (MSA) home to a census-estimated 3.8 million people. Kyoto is one of the oldest municipalities in Japan, having been chosen in 794 as the new seat of Japan's imperial court by Emperor Kanmu. The original city, named Heian-kyō, was arranged in accordance with traditional Chinese feng shui following the model of the ancient Chinese capital of Chang'an/Luoyang. The emperors of Japan ruled from Kyoto in the following eleven centuries until 1869.

Honshu
, historically called , is the largest and most populous island of Japan. It is located south of Hokkaidō across the Tsugaru Strait, north of Shikoku across the Inland Sea, and northeast of Kyūshū across the Kanmon Straits. The island separates the Sea of Japan, which lies to its north and west, from the North Pacific Ocean to the south and east. It is the seventh-largest island in the world, and the second-most populous after the Indonesian island of Java. Honshu had a population of 104 million , constituting 81.3% of the entire population of Japan, and is mostly concentrated in the coastal areas and plains. Approximately 30% of the total population resides in the Greater Tokyo Area on the Kantō Plain. As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyōto, Nara and Kamakura. Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several of the Japane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamakura Period
The is a period of Japanese history that marks the governance by the Kamakura shogunate, officially established in 1192 in Kamakura by the first ''shōgun'' Minamoto no Yoritomo after the conclusion of the Genpei War, which saw the struggle between the Taira and Minamoto clans. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan. During the early Kamakura period, the shogunate continued warfare against the Northern Fujiwara which was only defeated in 1189. Then, the authority to the Kamakura rulers waned in the 1190s and power was transferred to the powerful Hōjō clan in the early 13th century with the head of the clan as regent (Shikken) under the shogun which became a powerless figurehead. The later Kamakura period saw the invasions of the Mongols in 1274 and again in 1281. To reduce the amount of chaos, the Hōjō rulers decided to decentralize power by allowing two imperial lines – Northern and Southern ...

Double-flowered
"Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. The double-flowered trait is often noted alongside the scientific name with the abbreviation ''fl. pl.'' (''flore pleno'', a Latin ablative form meaning "with full flower"). The first abnormality to be documented in flowers, double flowers are popular varieties of many commercial flower types, including roses, camellias and carnations. In some double-flowered varieties all of the reproductive organs are converted to petals — as a result, they are sexually sterile and must be propagated through cuttings. Many double-flowered plants have little wildlife value as access to the nectaries is typically blocked by the mutation. History Double flowers are the earliest documented form of floral abnormality, first recognized more than two thousand years ago. Theophrastus mentioned double roses in his ''Enquiry into Plants'', written before 286 BC. Pliny also described doubl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prunus Serrulata
''Prunus serrulata'' or Japanese cherry is a species of cherry tree that grows naturally in Japan, China, and Korea, and it also refers to a cultivar produced from ''Prunus speciosa'' (Oshima cherry), a cherry tree endemic in Japan.Toshio Katsuki. (2015) ''Sakura''. p.137 Iwanami Shoten. Historically, the Japanese have developed many cultivars by selective breeding of cherry trees, which are produced by the complicated crossing of several wild species, and they are used for ornamental purposes all over the world. Of these, the cultivars produced by complex interspecific hybrids based on the Oshima cherry are also known as the ''Cerasus'' Sato-zakura Group. Varieties and Form Classification The classification of cherry blossoms varies from country to country and from period to period. For example, in the Japanese classification, ''P. serrulata'' Lindl. f. ''albida'', ''P. serrulata'' var. ''spontanea'', ''P. serrulata'' var. ''pubescens'' and ''P. serrulata'' Lindl. var. ''s ...

Sakura
A cherry blossom, also known as Japanese cherry or sakura, is a flower of many trees of Prunus, genus ''Prunus'' or Prunus subg. Cerasus, ''Prunus'' subg. ''Cerasus''. They are common species in East Asia, including China, Korea and especially in Japan. They generally refer to ornamental cherry trees, not to be confused with cherry tree, cherry trees that produce fruit for eating.Toshio Katsuki. (2015) ''Sakura''. pp.14–18 Iwanami Shoten. It is considered the national flower of Japan. Wild species of the cherry tree is widely distributed mainly in the Northern hemisphere. In the mainstream classification in Europe and North America, cherry trees for ornamental purposes are classified into the genus ''Prunus'' which consists of about 400 species. In the mainstream classification in Japan, China, and Russia, on the other hand, ornamental cherry trees are classified into the genus ''Cerasus'', which consists of about 100 species separated from the genus ''Prunus'', and the g ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
