Wanzhi: Cultivated in Hangzhou Wanjia Garden during the Tongzhi period of Qing Dynasty (1862--1874), hence the name Wanzhi. It is also known as the First Plum of Danghu Lake because it was found in Danghu Lake, Jiaxing, Zhejiang. Medium and short leaves, standing leaf posture, thick texture, deep grooves, rich luster. The three petals have rounded heads, thick flesh, tight edges, closed roots and horns, and the flowers bloom on flat shoulders or flying shoulders, with silk moths cupping the center, red dots at the end of the cupping, and a small ruyi tongue, with a long peduncle and a red peduncle with a green stalk. It is one of the best spring orchids with plum petals, and was formerly known as one of the four heavenly kings of spring orchids. Jiyuan, also known as ten rounds, old ten rounds, ten rounds of plum, is one of the "four heavenly kings" of spring orchids. It is said to have been discovered by Zhang Shenglin, an orchid artist from Yuyao County, Zhejiang Province, in the early years of Wei Feng (1850) of the Qing Dynasty, and later found by Gao Junfu in Hangzhou. It is named Jiyuan because the sepals of its flowers are spherical at the root. The leaves and flowers of Jiyuan are similar to those of Songmei, with broad, slightly drooping leaves, interspersed with fine drooping leaves, but the flowers are smaller. Flowers are plum petals, sepals and petals areole, petals are bright, flower color is slightly yellowish green, lip petals are small and rounded, lateral sepals are flat; sheaths are low, and bracts are green with reddish; flowering plants are 20-25cm high. flowers sometimes open plum-shaped daffodil petals, lateral sepals are slightly long and rounded. Flowering face is upright, strong, with a long flowering period. It is one of the most widely spread varieties of spring orchids because of its strong growth potential, easy cultivation, fast reproduction and easy flowering. It is native to Yuyao and Shaoxing, and is now more commonly cultivated in orchid nurseries and orchid lovers in Jiangsu and Zhejiang. Songmei was discovered 200 years ago during the Qianlong period of the Qing Dynasty (i.e. from 1736 to 1795), from Songjiadian of Wanghua, Pingshui Town, Shaoxing County, Zhejiang Province, and was cultivated by the family of Song Jinxuan, a native of Shaoxing, and so it is called Songjinxuanmei, or "Songmei" for short. It is said that the flower type at the early stage of discovery was a lotus-shaped daffodil petal, and after cultivation by many people, it gradually changed into plum petal, and became an outstanding and typical famous species of plum petal type in the spring orchid category. The Japanese listed Songmei, Jiyuan, Longzhi and Wangzhi as the "Four Heavenly Kings" of spring orchids, and Songmei was regarded as "the first of the Four Heavenly Kings of National Orchids". Songmei has green leaves, thick and slender, with a wide leaf width of 15 to 27 centimeters, 0.7 to 1 centimeter wide, glossy, and pointed at the apex; the old leaves are curved and slightly drooping, which is extremely beautiful, and the young leaves are thick green. The flowers are large, strongly fragrant, about 4 cm in diameter, with a downy sheen, and a pale emerald green color with a slightly bluish tinge; the sepals are very well defined, rounded and thick, but thinner all around, slightly inwardly rolled, tightly stemmed, with a slightly protruding top, pale green, and with both calyxes extending flat or falling slightly to the shoulders; the petals are young and white, curled up like a silkmoth, thick and soft, and are held together above the staminal column; the labellum is tightly adherent to the staminal column and is square and does not sag, and usually has one to two or more red spots; the new shoots have one to two or more red dots. There are usually one to two or more red dots; the new shoot sheaths are bright purple, and the bracts are light red; the scapes are above the leaf surface or several times as high as the leaf surface, and are light purple-red. Songmei has a strong growth potential, and although it is a noble species, it is easier to cultivate successfully; it is easy to bloom, usually one on each scape, and if it opens in the plum petal type, the three sepals are especially tightly rounded, and sometimes it can also open lotus-shaped daffodil petals or plum-shaped daffodil petals, such as when the plant is strong and vigorous, it also occasionally opens a scape of parallel double flowers. Songmei native to Shaoxing, Zhejiang Province, now Shaoxing County Orchid Nursery and *zhu, Tongdi, Shaoxing city around the orchid professional households are cultivated, Beijing, Shanghai, Nanjing, Hangzhou and other places have introduced cultivation.
