Paulownia ( paw-LOH-nee-ə) is a genus of seven to 17 species of hardwood trees (depending on taxonomic authority) in the family Paulowniaceae, the order Lamiales. The genus and family are native to east Asia and are widespread across China. The genus, originally Pavlovnia but now usually spelled Paulownia, was named in honour of Anna Pavlovna, queen consort of The Netherlands (1795–1865), daughter of Tsar Paul I of Russia. It is also called "princess tree" for the same reason. It was originally sought after as an exotic ornamental tree in Europe and Asia, and later introduced to North America

Sciadopitys verticillata, the kōyamaki or Japanese umbrella-pine, is a unique conifer endemic to Japan. It is the sole living member of the family Sciadopityaceae and genus Sciadopitys, a living fossil with no close relatives. The oldest fossils of Sciadopitys are from the Late Cretaceous of Japan, and the genus was widespread in Laurasia during most of the Cenozoic, especially in Europe until the Pliocene. A European relative of this species may have been the primary source of Baltic amber, according to some studies.

Prunus mume, also known as a Chinese plum, is a tree species in the family Rosaceae. It is also referenced by its flowers as plum blossom. Although referred to as a plum in English, it is classified in the Armeniaca section of the genus Prunus, making it an apricot. Mei flowers, or meihua (梅花), which bloom in the late winter and early spring, notably during the spring festival (春節), symbolize endurance, as they are the first to bloom despite the cold; the flower is one of the Three Friends of Winter. The plant is intimately associated with art, literature, and everyday life in China, from

Pinus parviflora, also known as Japanese white pine, is a pine in the white pine group, Pinus subgenus Strobus, native to Japan.

Pinus koraiensis is a species of pine known commonly as the Korean pine. It is a relic species of the Tertiary, identified as a rare tree species by United Nations. It is native to eastern Asia, in Korea, northeastern China, the temperate rainforests of the Russian Far East, and central Japan. In the north of its range, it grows at moderate elevations, typically 600 to 900 metres (2,000 to 3,000 feet), whereas further south, it is a mountain tree, growing at 2,000 to 2,600 m (6,600 to 8,500 ft) elevation in Japan. Other common names include "Chinese pinenut". The ancient woodland of P.

Castanea crenata, the Japanese chestnut or Korean chestnut, is a species of chestnut native to Japan and Korea. Castanea crenata exhibits resistance to Phytophthora cinnamomi, the fungal pathogen that causes ink disease in several Castanea species. The mechanism of resistance of Castanea crenata to Phytophthora cinnamomi may derive from its expression of the Cast_Gnk2-like gene.

Phyllostachys is a genus of Asian bamboo in the grass family. Many of the species are found in central and southern China, with a few species in northern Indochina and in the Himalayas. Some of the species have become naturalized in parts of Asia, South America, Australia, and southern Europe. The stem or culm has a prominent groove, called a sulcus, that runs along the length of each segment (or internode). Because of this, it is one of the most easily identifiable genera of bamboo. Most of the species spread aggressively by underground rhizomes. Being pioneer plants, phyllostachys species
