1: to distinguish between the requirements of light:

1. positive flowers: like light, such as magnolia, moon, pomegranate, plum blossoms, pansies, half lotus, etc.;

2. neutral flowers: light requirements are not strict. Such as jasmine, osmanthus, mallow, etc.;

3. Shady flowers: such as bamboo, bamboo, green, rubber tree, bamboo yu class, dragon white tree.

(2): according to the light requirement time is divided into

1. long sunshine flowers: daily sunshine more than 12 hours, such as iris, aster, bromeliads, etc.;

2. medium sunshine flowers: such as bamboo, moon season, etc.;

3. short sunshine flowers: daily sunshine must be less than 12 hours or less. Such as pincushion, chrysanthemums, etc.

(3):Temperature

1. Cold-hardy flowers: can tolerate low temperatures of about -20 degrees. Such as spring, begonias, elms, hairpins, lilacs, daylilies, wisteria, etc.;

2. Semi-cold-hardy flowers: can tolerate temperatures as low as minus 5 degrees, such as tulips, moon season, chrysanthemums, pomegranates, paeonies, etc.;

3. Non-cold-hardy flowers: such as bamboos, monocotyledon orchids, cranesbill orchids, variegated wood, pincushions, Fuchsia, calla lilies, albizia, and succulent plants.

(4): the importance of water in the flower

1. pay attention to water quality: according to the number of magnesium salts, calcium, hard water and soft water, watering flowers to soft water is good. Rainwater is ideal, followed by river water and pond water.

Remember: do not use dishwashing water or water with laundry detergent, tap water should be left to dry for a day before use, so that the chlorine in the water is fully evaporated.

2. Pay attention to the water temperature: do not sudden cold and hot.

3. The amount of water: spring more, it is appropriate to pour in the afternoon; summer enough, it is appropriate to pour early in the morning and late in the evening; less water in the fall; in winter, according to the wet and dry pots, a few days to water.

4. Watering note: according to the different seasons, the weather varies, plant preferences to master. In short, before watering, visual analysis of water shortage, and then water.

(5): flowers should also pay attention to the soil should not be hardened:

1. To increase the application of organic fertilizers; 2. Properly mixed with sand; 3. Drainage, loosening the soil.

(6): family flowers more compost production method

With grass, leaves, straw, etc., plus the right amount of water, livestock, human waste and a small amount of lime, into the pit piled up into a rectangular shape, with the soil cover, composting a certain period of time, both insecticide grass, but also to make the organic components of the rapid decomposition.

(7): fertilizer

1. extra-radical fertilizer;

2. urea fertilizer, also available urea water spray foliar;

3. Potassium phosphate conducive to the differentiation of flower buds, but also to make the flowers large, colorful flowers;

4. yellow leaves of the iron-deficiency, the best spray ferrous sulfate. Such as camellia, mast flower, hilaria, etc.;

5. Boron water, can prevent and reduce the fall of flowers and buds, to improve the number of flowers and flower quality is very good;

6. Fertilizer to pay attention to the amount of urea, potassium dihydrogen phosphate 0.2%-0.3%, ferrous sulfate 0.3%-0.5%, boron 0.05%-0.1%;

7. Fertilizer time is generally in the morning at 8-10 am or evening. point or evening, do not ignore the back of the leaf spraying.

(8):Family flower pest control

Pest control, should grasp the "prevention-oriented" principle, strengthen the management, pay attention to ventilation, light penetration, watering, fertilizer and other maintenance work.

To make the flowers and trees grow strong, enhance their ability to resist pests and diseases.

Once the pests and diseases are found, early measures should be taken to achieve "early, small, cure" to prevent the spread.

Common pests and diseases of flowers are introduced as follows:

1. Pests

(1) Aphids are a greenish-yellow bugs, almost harming all the flowers and trees. Between spring and summer, it is often dense in the moon season, pomegranate, oleander, chrysanthemum and other new tips or buds. Sucking sap with the mouthparts, causing young leaves to curl and shrivel, and in severe cases, not only affecting growth and flowering, but also making the plant wither. Aphids can occur 20-30 generations a year, and the eggs can overwinter.

Methods of control: spray with 40% Rogaine emulsion 3000 times (i.e., 3 kg of water added 1 gram of Rogaine emulsion); or 25% imidacloprid emulsion 1000 times spray. In addition, there are two simple methods of control: one is to use cigarette butts 5 grams mixed with 70-80 grams of water, soaked for 24 hours, slightly rubbed, filtered with gauze to remove the dregs, and then sprayed; the second is to use 1:200 washing powder water (soap water), in order to improve the effect of a few drops of vegetable oil can be added to the mixing fully, to the surface of the surface does not see the oil flower when sprayed with a sprayer.

(2) Stinging moth, commonly known as stinging caterpillar, itchy spice. This pest bites and eats the leaves of moon season, white orchid, peony, pomegranate, plum blossom, lotus, rose and so on. When the damage is severe, the leaves of the whole pot of flowers will be eaten up in less than a few days. The spiny moth specializes in lurking on the back of the leaves and is often overlooked if not noticed. Two generations occur in a year, one in early June, one in late June, and then cocoon in mid-October to overwinter.

Methods of control: If the pests are few and light, the victimized leaves can be removed and burned. Spraying 90% crystal trichlorfon 1000-1200 times liquid (that is, 1 kg of water to add trichlorfon 1 gram or a little more), or 50% fenitrothion emulsion 500-800 times liquid.

(3) Leaf mite, also known as red spider. Often harm azalea, moon season, a bunch of red, begonias, as well as cypress, kumquat, generation, cactus, cypress, etc., of which azalea, cypress is the most serious damage. Leaf mites are small, reddish in color and hard to see with the naked eye. Like in the back of the leaves to suck sap, the victimized leaves yellow, appear many small white spots, and soon withered and fall off. Leaf mite reproduction ability is very strong, can occur more than 10 generations a year, often in the high temperature and low humidity environment breeding.

Prevention methods: remove weeds in the pot, eliminate overwintering eggs. Pests Yang 40% of the Lego emulsion 1000-1500 times (that is, 1 kg of water to add Lego 1 ~ 1.5 grams), or 40% of the dicofol emulsion 2000 times spray,

(4) Tianniu, also known as dry worm, heartworm. It often harms grapes, moon season, azaleas, and peaches, apricots, plums and so on.

Prevention methods: Cut the trunk of the affected tree, capture and eliminate it. Or use a knife to remove the insect feces, wood chips, from the mouth of the cavity into the oxalic acid 1: 50 times the liquid, and then use mud to seal the hole.

(5) The Golden Turtle, also known as the white earthworm, white earthworm. Its larvae are called grubs, with a very mixed diet, and are the main underground pests of a variety of flowers.

Methods of control: Winter plowing and deep turning can promote the death of the overwintering generation. Watering 50% marathon emulsion 800-1000 times liquid during the activity period; protecting natural enemies.

2. Diseases

(1) Powdery mildew, also known as powdery mildew, endangers the moon season, roses, large-leafed poplar, kumquat and so on, often endangering the leaves, stems and flower stalks of flowers and trees. Victims of the surface of a layer of white powder, when the disease is serious, the leaves withered. This disease is easy to occur in a hot, humid, unventilated environment.

Control and Prevention Methods Tobramycin, carbendazim and other agents can be sprayed.

(2) white silk disease, for the moon season, jasmine, monarch, small pomegranate, peach leaf coral, orchids, chrysanthemums and so on. At the onset, the base of the stem is brown and rotting, the mycelium is silky, the first white, then yellow to brown. This disease occurs in the summer season when the soil is moist, rainy and hot.

Prevention methods Potting soil should be sterilized, while paying attention to environmental ventilation, avoiding overcultivation, pruning off diseased branches. Before the onset of regular spraying of 50% carbendazim wettable powder 500 times solution.

(3) Leaf spot disease, also known as black spot disease, brown spot disease. The moon season, camellias, azaleas, roses, chrysanthemums and other hazards, first black spots appear in the middle of the leaf, and then the leaves turn yellow and fall off. The cause of the occurrence of most of the environment caused by hot, ventilation and humidity.

Prevention methods: pay attention to improve environmental conditions, in the first onset of the disease can be removed from the damaged leaves, and will be burned. Can be sprayed with 1% Bordeaux solution to prevent and control, sprayed every 7 days, the whole growing period **** spraying 4-5 times.

Indoor foliage plant management calendar

Note: This calendar is based on Shanghai and Nanjing. How to control pests and diseases in home flowers, the northern region delayed by more than a month.

January Temperatures are cold and dry.

Daytime will like semi-shade and light-loving plants in the south window sill, to receive full light. At night, place them 1 meter away from the window sill, or add a cover to keep them warm. High-temperature plants need to be covered with plastic film during the day or placed in the glass made of heat preservation box. Conditional available artificial light source to increase the amount of light. Room temperature is low room, should take heating measures to prevent frost damage. Shade-tolerant plants in the light, dormant plants in the dark. Water once in about 4 days or more, when the soil is dry and white and hard:No fertilizer or a small amount of potash. Leaf surface with a damp cloth wipe dust moisturizing. Cut off the dead branches and yellow leaves in time.

February The climate is cold and dry, with occasional warm weather.

Maintain light and temperature as in January. Even if there is occasional warm weather, do not suddenly move outdoors into the sun or uninsulate the plant, as this could lead to frost damage. Water and fertilizer control is also the same as in January. Cold-hardy plants should be potted up, potted down, and potted out. Such as part of the bamboo, bamboo, etc., must be in the second half of the selection of warm weather. Cuttings of bamboos, octagonal gold plate and other cold-hardy plants. Plasticizing and pruning the same as in January.

March Temperatures begin to rise, light intensity gradually increased, but there is still a cold front. In addition to high temperature and some medium temperature plants continue to take anti-freezing measures, the rest of the plants can gradually lift the insulation to adapt to the room temperature, and appropriate ventilation, but the milk can not be immediately moved to the outdoors, you can take turns in the sun. Maintain humidity, a small amount of fertilizer, watering times increased appropriately, to create conditions for plant sprouting, but the soil is still not too wet, to maintain a certain air humidity. Sprinkle water on the foliage at noon in warm sunny days. Apply small amounts of all-vegetable fertilizers or fertilizers with a heavy dose of nitrogen and phosphorus. Continue to take cuttings of hardy plants such as anise, fuchsia, red-backed laurel, and loosestrife. Propagate red-backed laurel by division. Most of them can start to change pots, and combined with the change of pots for root pruning, posture, basal fertilizer, split-plant propagation, etc..

April Temperatures continue to rise, sunny, rain begins to increase, most of the plants begin to sprout.

Part of the heat-loving plants still need insulation management. The vast majority of plants can receive full sunlight, and appropriate ventilation. Light-loving, as well as cold-tolerant plants can be gradually exercise, placed outdoors to rotate the light, in order to maintain a good posture. Fertilizer can be applied posthumously, except for those that have just been potted, inverted, or repotted. Seedlings and cuttings that have begun to grow normally can also be thinly fertilized. Watering times increase, see dry and wet, often leaf spray, increase air humidity. Continue to cuttings of red back cinnamon, Fu Fang vine and other cold-hardy plants. Calla lilies, anise gold plate in the second half of this month to start sowing.

Continuing to catch up on potting, pouring and changing pots. As plants sprout and spread their leaves, top and center them in a timely manner. Rubber tree, purple-backed Jennifer bed and other heavy pruning and renewal. Sprawling plants tied bracket.

May Temperatures are getting warmer, sunny, more rain, plant growth began to accelerate.

First of all, do a good job of shade-tolerant, part of the semi-shade plants to prevent sun scorching, and appropriate ventilation. The rest of the plants can receive full sunlight to promote lush foliage. Fertilizer can be carried out before watering, appropriately increase the frequency and amount, but to prevent staining stems and leaves. After fertilization, watering and foliar spray in time. Watering is basically once a day, morning and evening, foliar spraying increased. Rainy season hardwood cuttings of Sprinkled Eastern Coral, Variegated Wood, Gooseberry, Cranesbill, and Octagonal Gold Plate can be started later in the month. Seeds continue to be picked and sown for the ten kingpins, octagonal golden disk, and calla lilies. Invert and replace pots of red mulberry and gooseberry. Rainy days on the sowing of seedlings to inter-seedling, set seedlings.

June Temperatures rise, humidity is high, the sun is strong, plant growth is rapid. Cold-weary plants also enter the long term.

Do a good job of shading and sun protection for shade-tolerant and semi-shade plants, and pay attention to indoor ventilation. Provide sufficient water, sunny and hot weather must pay attention to maintain air humidity. Fertilizer frequency and dosage should be increased. Intensify hard stem cuttings of variegated wood, oak, anise, gooseberry, and cranberry. Do a good job of propagating the cut stems of turtleback bamboo by division. Catch up on the potting of goosefoot and a few other plants.

This month, pay attention to prevent pests and diseases. Because the hot and humid weather, especially easy to induce fungal diseases, every 7-10 days spray Bordeaux solution 1 time. Pests and diseases found should be isolated and treated in a timely manner.

July The climate is hot, often hot weather, precipitation is large, but mostly by surface runoff, air humidity is low, the growth of plants have a negative impact. Mainly grasp the shade, water spray, ventilation cooling, humidification and other measures. Shade, semi-shade, light-tolerant plants to take different degrees of shade and sun avoidance measures, hot and dry weather when some of the light-loving plants at noon must also have a certain shade. Cuttings, sowing seedlings should pay particular attention. Enhance ventilation and aeration measures. Watering must be sufficient and timely, dry days can be 2 times a day in the morning and evening, avoid watering at noon, and set the water basin and increase the number of foliage, ground water spray, cooling and moisturizing effect. Fertilizer should be thin fertilizer, mainly nitrogen fertilizer, applied before watering. Summer dormant plants control water and fertilizer. Tsui cloud grass and ferns spore maturity, at any time to collect and spread propagation. Red mulberry, gooseberry, etc. can continue to cuttings propagation. Actively control pests and diseases. Same as June.

August The climate is hot and dry, there are still extremely hot weather, the second half of the day and night temperature difference driving large, favorable to the growth of plants. Light and temperature management with July. Water and fertilizer management with July.

September Temperatures are gradually declining, the temperature difference between day and night is large, the morning and evening cool, most of the plants open the second growth peak.

Part of the semi-shade plants began to gradually receive direct sunlight. Light-loving plants can receive full light throughout the day, but still need to be ventilated. The amount of watering is still adequate, and maintain air humidity. Fertilizer amount and frequency of old, gradually increase the proportion of potash fertilizer, reduce nitrogen fertilizer. Auspicious grass, calla lily and so on split plant reproduction. Appropriate plastic pruning.

October The climate is gradually cooler, plant growth began to slow down. Except for shade-tolerant plants, the rest of the plants gradually accept full light. Cold-intolerant plants are moved indoors one after another. Plants whose growth is gradually weakening start to control water and fertilizer after applying 1 fertilizer in the first half of the year. Normal growth of plants, the amount of watering should not be too much, in order to prevent futile growth, resulting in the weakening of cold tolerance, fertilizer to potassium-based. Jade hairpin and so on split root propagation. McDonald's and other seeds can be taken and sown to propagate.

November Temperatures drop significantly, the first cold snap begins to appear.

Most plants grow slower, and a few gradually enter dormancy. All plants, except hardy ones, should be indoors. Take steps to plug door and window gaps to prevent cold air from arriving at any time. All except shade-tolerant plants receive full sunlight. Heat-loving plants should be properly insulated and heated if necessary. The vast majority of plants require controlled water and fertilizer breaks to keep the soil properly dry. Palm seed collection and sowing propagation. Prune at any time to maintain good posture. Pruned branches can be used for cuttings the following year if stored properly.

December The climate is cold and dry.

Check the cold measures at any time, if the indoor temperature is not enough, should be strengthened in a timely manner: high-temperature-loving plants can be placed in a plastic film or glass made of warm box to improve the effect of heat preservation. The vast majority of plants can fully accept sunlight, light is insufficient, take artificial light source to make up for the light. At night, the pot should be placed 1 meter away from the door and window, can also add a cover to block the cold. Dormant plants in winter are placed in the dark. Continue to control water and cut off fertilizer. 3-4 days or longer watering once, the water temperature should be equal to or slightly higher than the air temperature, watering at noon. For winter dormant plants, keep the potting soil humid. Indoor heating is often easy to lead to low humidity in the air, you can often use a damp cloth to wipe the leaves, moisturizing and cleaning. Take the seeds of plants such as bamboo storage or pick and sow.

Indoor flowers and plants can "create" a good microclimate. With reinforced concrete prefabricated panels built into the modern building air humidity is much lower than the normal standard, and the desert. A plant called Salvia can turn a "desert" into an "oasis". Salvia likes water, so pots of Salvia should be placed in deep water tanks. Many of the flowers and plants that are suitable for growing indoors have antiseptic properties. If the room put some potted citrus, rosemary, mahogany, hanging orchids, etc., the air bacteria and microorganisms will be greatly reduced.

People in the suffocating room will feel suffocated, the reason is not the lack of indoor oxygen, but the negative oxygen ions strange lack. When there are televisions or computers on indoors, the negative oxygen ions will decrease rapidly. There are a number of flowering plants that can be grown indoors that produce negative oxygen ions - these are cypress, sidecar and willow.

If the indoor area is too small, it may be worth switching up the species and planting some low-growing plants, such as cacti. Spruce and other low-growing conifers are now popular on balconies in the West, where they can fill the room with a refreshing tree scent.

In the living room put some anti-pollution flowers and plants, can also play the role of air purifier. Such as: ivy can "eat" benzene, orchids can "eat" indoor carbon monoxide, formaldehyde, asparagus bracts can absorb benzene, trichloroethylene. If 10 square meters of living room has an anti-pollution plants, will greatly benefit the air purification.

Plants that can absorb toxic chemicals

Aloe vera, hanging orchids, tiger's tail orchid, orchid, turtle's back bamboo is a natural scavenger, can remove harmful substances in the air. Some studies have shown that the tiger's tail orchid and hanging orchid can absorb more than 80% of the harmful gases indoors, and the ability to absorb formaldehyde is super strong. Aloe vera is also good at absorbing formaldehyde, can absorb 90% of the formaldehyde contained in 1 cubic meter of air.

Ivy, ironwood, chrysanthemum, kumquat, pomegranate, sempervivum, moonflower, camellia, pomegranate, Milan, daisy, waxberry, marigold, etc. can effectively remove sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, nitrogen peroxide and other harmful substances.

Orchids, osmanthus, wax apple, leafy taro, red-backed laurel, etc. is a natural dust collector, its cilia can intercept and absorb floating particles and soot in the air.

Plants that kill germs

Roses, osmanthus, violets, jasmine, lemons, roses, gypsophila, lily of the valley, yew and other aromatic flowers produce volatile oils that have a significant bactericidal effect.

Plants such as violet, jasmine, lemon, etc., can kill protozoa such as diphtheria and dysentery bacteria within 5 minutes. Roses, Dianthus, lily of the valley, violets, roses, osmanthus and other plants emit a scent on the growth and reproduction of tuberculosis bacilli, pneumococcus, staphylococcus has a significant inhibition of the growth and reproduction.

Cacti and other succulents native to tropical arid regions have stomata on their fleshy stems that close during the day and open at night, absorbing carbon dioxide while creating oxygen and increasing the concentration of negative ions in indoor air.

The tiger orchid, tiger's tail orchid, and agave, as well as the brown hairy palm, galangal, Sedum, ground elder, and cultivated bromeliad can also purify the air at night.

Planting climbers, grapes, petunias, wisteria, roses and other climbing plants around the home and letting them climb along the walls or along the shelves to form a green pergola can effectively reduce the sun's radiation and greatly reduce the indoor temperature.

Lilacs, jasmine, roses, violets, peppermint and other plants can make people relax, happy spirit, conducive to sleep, but also improve work efficiency .

Many people like to raise flowers indoors to improve and beautify the indoor environment, but if the choice is not appropriate, but will cause indoor pollution. Therefore, flowers should pay attention to:

Choose a good variety of indoor best choice of evergreen flowers and trees or can absorb toxic gases of the species, such as orchids, manzanita, Mannix, cactus, bamboo, ivy and so on.

It is not appropriate to raise the flowers lilac, nightshade at night can emit particles that stimulate the sense of smell, high blood pressure and heart disease patients have a negative impact; oleander flowers can make people drowsy, lower intelligence; hydrangea particles emitted by the skin allergies occur itching; tulip flowers poisonous alkali, excessive exposure to easy to make the human hair fall off; pines and cypresses emitted by the flowers and trees of the oil fragrance, will affect the appetite.

Don't raise the "grams" flowers rose and rhinoceros together, rhinoceros will wither, but rhinoceros in the withering before the release of a substance to make the rose poisoning death. Yume, orchids, Dianthus, violets, lilies and other grasses and other flowers are difficult to get along, resulting in plant death.

Patients do not keep flowers indoorsThe fungal spores produced by the soil in the flower pots will spread into the indoor air, causing surface or deep infections in the human body, and may also invade the human skin, respiratory tract, external auditory canal, meninges and the brain and other parts of the body. This was already suffering from disease, poor health patients, such as adding insult to injury, especially for leukemia patients and organ transplants more harmful to the Liaoning Provincial Landscape Architecture Society expert group in charge of Prof. Li Wenzhu answered these questions, he believes that the "drip Guanyin" worry is redundant, it is not in the 52 kinds of cancer-promoting plants. Although it has toxicity, but can be assured to keep. In fact, many residents at home flowers are toxic. Bamboo is a natural scavenger, can remove harmful substances in the air, but it is also a poisonous flower. Green evergreen and can absorb toxic gases, but the green juice is toxic, touching the skin will cause red itch, accidentally eaten will cause throat pain; Vanda is the lily family, toxic parts in the rhizome, accidentally eat a lot of rhizomes will appear nausea, abdominal pain, chills in the limbs and even coma symptoms. And zebra wannabe, the sap of the leaves can make a person mute.

Guo Xichang, a professor at the forestry department of Shenyang Agricultural University, believes that plants in the Euphorbiaceae and Ruixiang families are also poisonous, for example, like the unicorn's crown, one of the 52 types of cancer-promoting plants, or don't breed at home. But toxic flowers that can purify the air in your home, like the drip water goddess of mercy and green roses, are completely unnecessary to smash.

Experts believe that the attitude toward toxic plants should be: keep a proper distance, do not play with touch; can not be branches, leaves and fruits in the mouth.

Experts also summed up 10 kinds of flowers should try to avoid placing in the bedroom: such as orchids will cause insomnia; mimosa may cause hair loss; zinnia pollen will trigger asthma and aggravate cough; nightshade can cause dizziness; lily fragrance can cause insomnia; moonflower scent is depressing; oleander secretion of milky white liquid will be poisonous; pines and cypresses aroma of loss of appetite; hydrangea allergy-inducing; tulip flowers can cause hair loss.

For the winter indoor flowers, two professors also made some suggestions: indoor flowers is not the more the better. 15 square meters of the HOS, it is only appropriate to put 2 pots of medium-sized, large plants, while small plants can be put three or four pots.

Aloe vera

Family pots of aloe vera, not only can beautify the room, but also can be picked at any time, to get the freshest aloe vera leaves for family health care use. Some people say that planting a few pots of aloe vera at home is equivalent to hiring a resident "private doctor". This is an exaggeration, but it is not entirely without reason. Aloe vera, whether used as medicine to cure diseases, or used for beauty care, only use fresh aloe vera to get the best results.

Aloe vera has a very high ornamental value. Although the flowering period of aloe vera is short, but the color of the flower is also very colorful, very popular. Small potted aloe vera can be placed on the desk, large plants potted back in the courtyard, and other succulents to match, forming a unique natural landscape, interesting. In winter, and can be moved to the lobby hall for indoor furnishings.

Aloe vera not only photosynthesizes during the day, releasing oxygen, but also absorbs carbon dioxide at night, purifying the indoor air. Aloe vera can effectively remove formaldehyde in the air, plant a few aloe vera, is equal to the installation of a few "biological air freshener" at home, all the time in the purification of the living environment. When the harmful gases in the air, such as carbon monoxide, carbon dioxide, sulfur dioxide, formaldehyde, long-term at a high level, and aloe vera has been unable to completely remove the absorption, will appear in the leaf spot, the alarm you quickly take appropriate measures to avoid harmful gases on human health hazards.

Hanging orchid, originating in South Africa, the family belongs to the lily family, it is adaptable, more drought-resistant, cold-resistant, sex like warm and moist, suitable for growth in loose and fertile, well-drained soil.

The hanging orchid is one of the most traditional hanging plants. Its leaves are slender and soft, from the leaf axils of the stem of Dian Dian long with a small plant, from the edge of the pot to the downward hanging, stretching and hanging, like flowers, evergreen; it is both rigid and soft, like the wings of the crane jumping, so there is an ancient "folding crane orchid" called. It also has the nickname of pendant grass, laurel orchid, hook orchid, and in Western Europe, it is also called spider grass or airplane grass.

Cranesbill is not only an excellent indoor hanging foliage plant, but also a good indoor air purification flowers. Hanging orchids have a strong absorption of toxic gases, can purify carbon monoxide, carbon dioxide, formaldehyde and other toxic gases. The general room to raise l a 2 pots of orchids, air toxic gases can be absorbed, so the orchid also has a "green purifier" of the name.
