3. Purify the air

As a greening plant, holly tree has a high effect of purifying the air, can absorb carbon monoxide, sulfur dioxide and carbon dioxide in the air, and can release oxygen after transformation in the body, which is beneficial to human health when placed indoors, and can also absorb car exhaust and improve air quality when planted on the roadside.

4. Strong adaptability

Holly tree vitality is vigorous, strong adaptability, can adapt to the surrounding environment in a short period of time after planting, and the plant does not have high requirements for soil quality, and can grow in poor soil in time, only need proper watering in the breeding process, give sufficient light, the plant can thrive.

Why are holly trees evergreen?

Holly is an evergreen tree with an oval crown and smooth, grayish-cyan bark. Twigs light green.

The leaves are alternate, oblong-elliptic, thinly grassy, with sparsely shallowly serrated margins, dark green on the surface, shiny.

The flowers are solitary, dioecious, arranged in a clustered inflorescence, with branches and leaves axils; The flowers are pale purplish-red and fragrant.

The drupes are oval-shaped, dark red when ripe, and do not fall in winter. The flowering period is May, and the fruit ripening period is from October to November.

1. Camellia.

Camellia is not only resistant to cold and freeze, but also an evergreen plant that blooms in winter, can withstand low temperatures of minus 8, and its large and beautiful flowers are deeply loved by flower friends. Camellia has a long bud period, which can even reach half a year, so it takes patience to wait for it to bloom.

2. Rhododendrons.

Rhododendron is a slightly hardy flower, able to withstand temperatures as low as -3. China is the country with the most varieties of rhododendrons, and there are azaleas everywhere, although there is a certain ability to withstand cold, but if it is a potted azalea, it is best to move it indoors in winter to maintain.

3. Gardenias.

Gardenias can tolerate temperatures as low as minus 5, and the leaves may freeze and fall off at any lower temperatures. However, gardenias of small-leaved varieties are not very hardy, so you should pay attention when choosing varieties to plant.

Fourth, dwarf cypress. When it comes to evergreen plants that do not freeze in winter, cypress is certainly one of them, and dwarf cypress is a particularly low cypress species, also known as creeping cypress, which can not only maintain green all year round, but also withstand the low temperature environment of minus 10, and can survive the winter well.

5. Winter heather.

Winter heather is a relatively dwarf evergreen shrub with high ornamental value and is very suitable for potted maintenance. Generally speaking, plants that can bloom in winter are relatively resistant to low temperatures, and the flowering period of winter heather is in January and March, and the flowers are fresh and pleasant in clusters.

Almost all pine species are evergreen (except for the golden pine), such as cedar, tabuliformis, masson pine, marsh pine, etc.

cypresses; Arborvitae, Thousand Dou Cypress, Dragon Cypress, Juniper Cypress, etc.

There are also magnolia, ten merits, osmanthus, camphor, smiling, tung, mosquito mother tree, coral tree, large-leaved boxwood, holly, bone, superba, octagonal golden plate, privet, huangxin, oleander, nantian bamboo, etc.

The pine tree is one of the most widely distributed tree species in the world, and its beautiful evergreen leaves attract the attention of countless people. As we all know, the pine tree is evergreen all year round, so why do its leaves remain evergreen?

The structure of pine leaves.

First, we need to understand the leaf structure of pine trees. The leaves of the pine tree are needle-shaped, with a smooth surface and a sheath-like leaf base. A leaflet consists of 3 5 long, thin needles connected by a short leaf stalk, each of which is far apart.

The veins, on the other hand, are unbranched and appear distinctly white lines along the edges of the leaves. This foliage structure makes pine trees ideal for growing in dry and cold environments.

Nutrition of pine leaves.

Secondly, pine leaves have a high calorific value and nutritional value. Pine needles are rich in pine alcohol, pine resin, rosin and biophenols, which can be used as a natural antioxidant and immune enhancer, and can also play a role in preventing and improving some diseases.

Adaptability of pine leaves.

The leaves of the pine tree are also highly adaptable and can survive in harsh environments. The surface of the leaves of the pine tree is covered with a thin layer of waxy substance called leaf wax. This leaf wax reduces water loss, allowing pine leaves to remain green and vibrant when exposed to drought and heat.

The growth cycle of pine leaves.

Finally, the pine tree is evergreen all year round, which means that its god dust leaves do not turn yellow and fall in autumn like other trees. Pine trees have a longer leaf growth cycle than other trees and can sprout new shoots at any time of the year and grow continuously. This is one of the main reasons why pine trees can remain evergreen all year round.

Epilogue. Overall, the reason why pine trees remain evergreen all year round is the result of the combination of factors such as its special leaf structure, high nutritional value, strong adaptability, and long growth cycle. The evergreen sight of pine trees also makes us deeply feel the strength of life and the inexhaustibility of vitality.

There are usually two kinds of four seasons of green, one is the same as the holly tree planted on the green belt, and the other is different.

The same kind of quadrills are plants belonging to the genus Holly in the family Holly. It is distributed in the south of the Yangtze River in China, and often grows in sparse forests. Its roots and leaves can be used for medicine, and its main effect is to clear heat and detoxify; myogenic sores; Invigorate blood and stop bleeding.

Evergreen trees that can reach up to 12m in height. As shown below:

The different kind of four-season green is a perennial grass, a plant of the genus Poaceae, 20cm high. The base of the erect stem is bent at the knee or lying flat. The leaf sheath is slightly purple, and the leaves have small prickly hairs.

The panicles are ovate-oblong, greenish-purple, copper-colored when mature, and the flowering period is 6 to 8 months. As shown below:

It's not the same. Four seasons are four seasons green, and holly is French holly. Sijiqing generally has small seedlings and balls.

In the case of French holly, it belongs to small shrubs, and of course there are large trees. Often as a hedge.

If you want to talk about the difference, I personally think that the four seasons are still greener than the French holly tree. It's that dark green.

Ordinary deciduous trees turn yellow and lose their leaves in autumn and winter because the climate is not suitable, because the leaf area is large and there is no waxy film on the surface, which causes the water to disperse quickly and is not easy to survive.

Pine, holly, cypress, etc., because the leaves are either pointed and thin, or have a waxy layer on the surface, and the water is not easy to lose, so they can still survive normally in harsh environments, so they will not lose their leaves and remain evergreen.

The pine tree is a tree like no other:

When we ride or walk in the cold winter, we can always see many trees on both sides of the wide road, and they are all covered with white coats, and the leaves are all gone.

Accustomed to seeing this monotonous white, it is inevitable that our eyes will be a little tired, but when we look carefully, we can still find the dots of green, which dot the northern land. And this is the pine tree, this kind of tree that is not afraid of the cold.

The pine tree is evergreen mainly because of the unique shape of its leaves, which are generally reduced to needle-shaped, linear or scaly-shaped, and because of the small leaf area, it is not easy to evaporate and lose water.

Some leaves have thick or waxy leaves, and some have thick hairs, such as taking a pine needle and looking closely, you can see that there are dense white hairs on it, which feel smooth when touched, and these structures effectively prevent the evaporation of water.

When the temperature drops, the concentration of cell fluid can quickly increase, increase sugar and fat in order to prevent freezing, so, even in winter, the pine tree will not lack water and dry up, ensuring the vitality of the tree forever, the growth cycle of pine leaves is relatively long, generally 3 to 5 years, and the leaves fall irregularly, so you will see pine trees evergreen in all seasons.

Extended content. There are more than 80 kinds of pine trees in the world, not only many species, but also widely distributed, such as Pinus tabuliformis, Pinus sylvestris, Black Pine and Scots Pine distributed in North China and Northwest Provinces, Masson pine, Huangshan pine, alpine pine in Central China, Bashan pine in Qinba Mountains, as well as Taiwan pine and North American breviphyllous pine, most of which are the main tree species for afforestation in barren mountains in China.

Deciduous trees lose their leaves because they need to reduce water evaporation. Pine trees are coniferous and retain water well, so they don't need to lose their leaves every year, and they usually fall every 5 years. Because the plant can not withstand the cold winter and low temperature caused by the nutrient transfer efficiency is getting lower and lower, and finally because of this problem and yellow, leaving only cold-resistant seeds and grass and leaves, living leaves and grass have chlorophyll, when autumn comes, the leaves begin to transfer green to the trunk or grass roots, so that the leaves can only leave iron elements that can not be transferred, and the leaves will become yellow when they die.

The pine tree is evergreen because its leaves have evolved into pine needles, so that less water is evaporated and more chlorophyll is retained. And the pine tree is not not deciduous and it is constantly changing leaves, but there are not so many leaves that fall at a time, and the time of falling leaves is also at different times of the four seasons.

The life span of pine leaves is longer, 1 to 5 years per month, and the irregular falling leaves help you check what everyone asked, in fact, this answer is okay.

But I remember that not all pine trees seem to be like this.

Pine trees are evergreen plants. The leaves of evergreens are green all year round, but that doesn't mean they don't shed their leaves. The pine tree loses its leaves in all seasons, but at the same time it grows new leaves.

Its leaves are very small, and the leaves of the pine tree are like needles. Not only that, but there is also a waxy cuticle on the surface of its leaves, which protects the leaves from the outside world at all times.

In the cold and dry winter, the green leaves are not afraid of the cold at all. Especially when the snow is falling, the pine trees are even more vigorous and energetic.

Because of the scientific truth, Einstein was unreasonable.

There is a typo in the penultimate line of the answer.
