A scorpion with strong vitality

People are still relatively unfamiliar with this kind of flowers and trees. Because it is rarely planted in gardens in Beijing, it can't be found in the streets. However, in Beijing Botanical Garden, Castanopsis fissa has been planted for twenty years. However, due to insufficient publicity, it is little known.

Castanopsis fissa belongs to the genus Castanopsis of Rosaceae. Cotoneaster plants include Cotoneaster, Cotoneaster (with creeping branches, also known as "centipede", also native to India, Myanmar, Nepal and other countries), Cotoneaster (2 to 3 meters high) and Cotoneaster microphylla. Castanopsis kawakamii is a special product in China and a semi-evergreen low-flowering shrub. Evergreen in the south, deciduous or semi-deciduous in winter, deciduous or semi-deciduous in Beijing in winter. It is about 50 to 100 cm high. Its branchlets spread outward and grow in parallel, which seems to be layer by layer, hence the name "Pingzhi". Its leaves are small oval, about 0.6 to 1.2 cm long, and the leaves are staggered from left to right on the branches. The flowering period of Osmunda glabra is in May and June. Petals of small flowers are erect, obovate, 0.5 to 0.8 cm long, with one or two flowers in bundles and pink flowers. The fruit ripens in June 5438+1October. Castanopsis fissa is native to Sichuan, Yunnan, Guizhou, Hunan, Hubei and Qinling in China. For the wild, it grows on the mountain at an altitude of 1000 m to 3500 m, and can be seen everywhere in dense forests, rocks and streams on the mountain. Castanopsis fissa has strong vitality and can grow well without special management. Although it is native to the south, it is very cold-resistant because it is on a high mountain. It grows well in Beijing Botanical Garden and does not need special cold protection in winter. Beijing Botanical Garden was introduced from Aba, Sichuan. The natural conditions on the mountain in Aba area of Sichuan are very suitable for the growth of Cotoneaster, so "Aba Cotoneaster" is a famous product of Cotoneaster. Beijing can vigorously develop the cultivation of litchi. The propagation method of Castanopsis fissa, if used in large quantities, can be seeded and cut. If the amount is small, it can be layered at any time, and the survival rate of ramets is very high.

The main ornamental value of three-leaf poplar is the red leaves in late autumn. In late autumn, the leaves of the broad-leaved scorpion turn red, which is especially beautiful. Because the flat branch is low, it looks like a fireball from a distance and is very bright. Every year in late autumn, photographers are often attracted by its bright red leaves in the botanical garden, which becomes an accidental discovery and takes pictures of it. The flowers and fruits of Lisong also have ornamental value. Its flowers bloom in early summer, but its pink flowers bloom silently in green. The pink flowers contrast with the green leaves, which is especially beautiful. The fruit of Castanopsis fissa is a small red ball, which never falls in winter. It's interesting to watch on snowy days. In fact, Li Guo is a good garden plant, especially in the garden, accompanied by rockeries and rocks, dotted with lawns and streams, which set each other off in beauty. The twigs of Li Guo are parallel layer by layer, so the tree shape is also beautiful.

Among the many open flowers and trees in China, Populus triloba is also beautiful, although it is not as famous as peony, plum blossom, magnolia, begonia, peach blossom, clove and other precious flowers and trees, and even its name can not be found in some flower books. However, it grows silently. It is not afraid of cold and has strong vitality. It can grow in most parts of the motherland.
