Ginkgo bilobaGinkgo biloba, commonly known as ginkgo or gingko (ˈɡɪŋkoʊ,_ˈɡɪŋkɡoʊ ), also known as the maidenhair tree, is a species of gymnosperm tree native to China. It is the last living species in the order Ginkgoales, which first appeared over 290 million years ago. Fossils very similar to the living species, belonging to the genus Ginkgo, extend back to the Middle Jurassic epoch approximately 170 million years ago. The tree was cultivated early in human history and remains commonly planted.
Ikebanaor is the Japanese art of flower arrangement. It is also known as kadō. The tradition dates back to Heian period (794–1185), when floral offerings were made at altars. Later, flower arrangements were instead used to adorn the tokonoma (alcove) of a traditional Japanese home. Ikebana reached its first zenith in the 16th century under the influence of Buddhist tea masters and has grown over the centuries, with numerous distinct schools extant today.
DeciduousIn the fields of horticulture and botany, the term deciduous (dɪˈsɪdʒu.əs) means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished".
Edo periodThe Edo period or Tokugawa period is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's 300 regional daimyo. Emerging from the chaos of the Sengoku period, the Edo period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, perpetual peace, and popular enjoyment of arts and culture, colloquially referred to as Oedo.
CultivarA cultivar is a kind of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars.
SamuraiSamurai were the hereditary military nobility and officer caste of medieval and early-modern Japan from the late 12th century until their abolition in the late 1870s during the Meiji era. They were the well-paid retainers of the daimyo, the great feudal landholders. They had high prestige and special privileges. Following the passing of a law in 1629, samurai on official duty were required to practice daishō (wear two swords). Samurai were granted kiri-sute gomen: the right to kill anyone of a lower class in certain situations.
