The succulent plants are becoming more and more popular in the field of flower cultivation. The first one to bear the brunt is the succulent plants of Crassulaceae. As the main family and genus of Sedum, there are more and more flower friends. In order to let Huayou better understand the fleshy habit of Eupatorium and better raise her, Xiaobian will introduce the classification and varieties of Eupatorium and the key points of conservation in detail for you!
The origin of the succulent plants of the genus Lolium is central and southern Europe, North Africa, Caucasus and Asia Minor (East Asia). They are gradually distributed in Asia and America, including the hills of China, Japan, Myanmar, India, North America and Canada.
Latin name: genus names are the Latin words Semper (eternal) and vivium (growing).
Chinese Name: Eupatorium, arachnoidea (named by Japanese botanists)
At the beginning, 23 varieties of the genus Eupatorium were discovered (1930s). After "Huo", the number of species in the genus increased rapidly, mainly because the succulent plants in the family were easy to cross, and the name and quantity were very confused.
For example: S. tectoram, which has more than 500 varieties and more than 70 scientific and cultural names! Some of them are early natural hybrid varieties and varieties. After screening, there are 50 varieties.
In the middle period of Meiji in Japan, the succulence of the genus macrophyte began to be popular and widely propagated. In recent years, the introduction of more meat into China, most of which began in Japan. The most common family breed of Eupatorium is Juan.
The long-lived grass is a kind of perennial succulent herb with thick leaves and rosette like whorls, compact leaves and filiform hairs. Perennial grass is a kind of flower, cymose panicle; it has red, yellow, white, green and other colors. It is similar to the genus Anthurium.
The long-lived grass is very cold resistant and sensitive to high temperature. In reproduction and cultivation, it is necessary to keep air circulation, especially in summer, it is easy to black rot.
Humus soil is selected for soil selection, and sandy soil is used for the upper layer, with slight acidity. The propagating species can be divided into plants and leaves, and the seeds can be easily obtained by hybridization. It should be noted that do not water from the top of the plant, otherwise it will make the silky hair disappear and affect the ornamental value.
There are mainly leaf eating pests and molds. Generally, insecticides are effective against pests, and generally have strong resistance to disease.
Because of the easy hybridization between natural state and artificial state, there is a great controversy on the classification of families and genera.
In the early days, the succulent people generally divided the genus into two subgenera: Sempervivum and jovisbarbara, which are now generally divided into two groups. In recent years, scholars have been sorting out the early varieties and confirming the origin species in Europe, which will make the classification more scientific.
Juan: the leaves are all green, with spider like silky hairs at the tip. This species began to be popular in the 1940s, and now it is more common, but it is a beautiful variety.
Dahongjuan: a horticultural cultivar, with a plant diameter of 6-7cm. There are hairs on the leaf margin, almost no hairs and filiform hairs on the leaf. The leaf apex is wide, the leaf tip is obvious, and the leaf base is red. After autumn, the plant gradually turns red, and the branch is short. Winter and spring are the growing seasons.
Purple peony: there are short white hairs on the leaf margin, and the plant in late autumn changes from leaf base to dark red.
Silk: the tip of the leaf is red for many generations, only a small amount of pekoe is on the edge of the leaf, and the whole plant is hairless.
In addition, there are: Dahua silk, silk, Wu's longevity grass, Shengdai, Ling Ying, etc.
Because the long-lived grass is easy to hybridize in the natural state, more than 200 varieties have been produced. In the middle of the 19th century (1853-1870), a large number of studies have been carried out, and the relationship between the three naturally hybridized varieties arachnoideum, montanum and wulfenii has been found, and then they have been found to be related to tectorum and grandiflorum. A prospective basic study on the hybrid relationship between the genus and artificial hybrid was made.
Xiaobian finally just want to say: your circle is really messy!!
