The peony or paeony is a flowering plant in the genus Paeonia, the only genus in the family Paeoniaceae. Peonies are native to Asia, Europe and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further clarified. Peonies are among the most popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer. An emerging source of peonies in mid to late summer is the Alaskan market. Unique growing conditions due to long hours of sunlight create availability from Alaska when other sources have completed harvest. The peony is among the longest-used flowers in Eastern culture. Along with the plum blossom, it is a traditional floral symbol of China, where the Paeonia suffruticosa is called 牡丹 (mǔdān). It is also known as 富貴花 (fùguìhuā) "flower of riches and honour" or 花王 (huawang) "king of the flowers", and is used symbolically in Chinese art. In 1903, the Qing dynasty declared the peony as the national flower. Currently, the Republic of China government in Taiwan designates the plum blossom as the national flower, while the People's Republic of China government has no legally designated national flower. In 1994, the peony was proposed as the national flower after a nationwide poll, but the National People's Congress failed to ratify the selection. In 2003, another selection process was initiated, but no choice has been made to date.
The ancient Chinese city Luoyang has a reputation as a cultivation centre for the peonies. Throughout Chinese history, peonies in Luoyang have been said to be the finest in the country. Dozens of peony exhibitions and shows are still held there annually. In the Middle Ages, peonies were often painted with their ripe seed-capsules, since it was the seeds, not the flowers, which were medically significant. Ancient superstition dictated that great care be taken not to be seen by a woodpecker while picking the plant's fruit, or the bird might peck out one's eyes. In 1957, the Indiana General Assembly passed a law to make the peony the state flower of Indiana, a title which it holds to this day. It replaced the zinnia, which had been the state flower since 1931. Mischievous nymphs were said to hide in the petals of the Peony, giving it the meaning of Shame or Bashfulness in the Language of Flowers. While the peony takes several years to re-establish itself when moved, it blooms annually for decades once it has done so. Peonies tend to attract ants to the flower buds. This is due to the nectar that forms on the outside of the flower buds, and is not required for the plants' own pollination or other growth. The presence of ants is thought to provide some deterrence to other harmful insects though, so the production of ant-attracting nectar is plausibly a functional adaptation.Peonies are a common subject in tattoos, often used along with koi-fish. The popular use of peonies in Japanese tattoo was inspired by the ukiyo-e artist Utagawa Kuniyoshi's illustrations of Suikoden, a classical Chinese novel. His paintings of warrior-heroes covered in pictorial tattoos included lions, tigers, dragons, koi fish, and peonies, among other symbols. The peony became a masculine motif, associated with a devil-may-care attitude and disregard for consequence. Famous painters of peonies have included Conrad Gessner (ca. 1550) and Auguste Renoir in 1879. Paeonia officinalis can be found in the altar picture of Maria im Rosenhag by Schongauer in the former Dominican Church in Colmar.The Italian Jesuit, painter and architect Giuseppe Castiglione (1688-1766), who worked at the court of the Qianlong Emperor in the Qing dynasty, painted peonies.

Today, we are going to introduce 7 ways to make fertilizer that you can easy to handle with at home. Let's take a look! 1.Use water from a freshwater aquarium. Freshwater aquariums contain nitrogen, which can provide your plants with a healthy boost. Fish naturally release nitrogen into the water, making their "waste" water an important source of nutrients for plants. Instead of dumping it down the toilet, use it to water your plants once a week. Fish waste, as well, contains trace elements important for plant growth.
2.Create a coffee compost. Mix coffee grounds with leafy yard waste for "quick compost," especially for acid-loving plants. Mix your coffee grounds with an equal amount of dead leaves, pine straw, and other brown yard clippings and sprinkle over the soil once a month. Roses, azaleas, hydrangeas, and many other plants crave a low pH soil and will respond particularly well. 3.Use eggshells. Spread old eggshells over your garden, or in the bottom of planting holes, for a calcium boost. Plants like tomatoes and peppers particularly love calcium, but your whole garden will enjoy eggshells. Calcium, which is over 90% of an eggshell's makeup, helps a plant develop strong cell walls. To use eggshells, lightly crush up the shells and spread over the garden. You can till them into the soil or leave them right on top -- they decompose very quickly.
4.Brew grass tea. Make a "nutrient tea" with grass clippings from your yard. Use the bag on your lawnmower to keep the clippings the next time you cut the grass. Use them to fill up a 5-gallon bucket roughly 2/3s of the way to the top, then fill it near the top with water. Stir it quickly, then let it sit for three days, stirring once each morning. When done, strain out the grass clippings and use your "tea" to water your plants, providing essential nitrogen, by mixing it with an equal amount of water and spraying over the plants. 5.Save and spread your fireplace ashes. Wood ash is high in calcium and potassium, making it an excellent supplement to your soil. Simply spread it right over the garden, using your hands to lightly turn it into the top layer of the soil. *Vegetables, in particular, tend to love ash, as it promotes healthy root growth. *Warning: Do not use fireplace ashes on plants that love acidic soil like blueberries, roses, or azaleas.
6.Try banana peels. Cut up banana peels and add them to the hole when planting. Banana peels don't do much once the plant is already in the ground, but it can work wonders as you're planting. The peels contain a lot of potassium, which promotes a plant's root development. Cut up half a banana peel and toss it in the bottom of your hole before adding the plant. 7.Make your own compost. Composting at home is easy, so you can turn all of your old food scraps, leaves, and plant clippings into food for your garden. When organic matter decays, it releases nutrients that can enrich your soil. You can build your own compost in your yard, or you can try one of the commercially-available kitchen compost units. via wikihow

There are many plants that can be regrown indoors, which is very convenient for green hands to try gardening. Today, we are going to introduce 7 kinds of plants to you to regrow in water. Let’s take a look! 1.Carrots Greens
Instead of defaulting to the compost, use carrot tops to grow healthy carrot greens. Place a carrot top or tops in a bowl, cut side down. Fill the bowl with about an inch of water so the top is halfway covered. Place the dish in a sunny windowsill and change the water every day. The tops will eventually sprout shoots. When they do, plant the tops in soil, careful not to cover the shoots. Harvest the greens to taste. (Some people prefer the baby greens; others prefer them fully grown.) (Instructions via Gardening Know-How) 2.Green Onion
Instead of tossing the green part of these veggies, use them to grow more. Place the greens in a cup or recycled jar filled with water. Put the cup or jar on a windowsill and change the water every other day. In about a week, you should have a new green onion, leek, and/or scallion to add to your supper. Harvest when fullygrown—just make sure to leave the roots in the water. (Instructions via Living Green Magazine) 3.Bok Choy
Cut off the base of a bok choy plant and place it in a bowl bottom-down. Add a small amount of water in the bowl. Cover the whole base with water, but do not add more than 1/4 inch above the base. Replace water every few days. In about one week, you should see regrowth around the center of the base. Once you see regrowth, transfer the plant to a container or garden. Cover everything except the new growth with soil. Your bok choy should be full grown and ready to harvest in approximately five months. (Instructions via My Heart Beets) 4.Celery
Rinse off the base of a bunch of celery and place it in a small bowl or similar container (any wide-mouthed, glass, or ceramic container should do). Fill the container with warm water, cut stalks facing upright. Place the bowl in a sunny area. Leave the base as-is for about one week and change the water every other day. Use a spray bottle to gently mist the plant every other day. The tiny yellow leaves around the center of the base will grow thicker and turn dark green. After five to seven days, move the celery base to a planter or garden and cover it with soil, leaving the leaf tips uncovered. Keep the plant well watered. You’ll soon notice celery leaves regenerate from the base, as well as a few small stalks. Harvest when fully grown, then repeat the process. (Instructions via 17 Apart) 5.Romaine Lettuce
When you chop up hearts of romaine, set aside a few inches from the bottom of the heart. Place in a bowl with about a ½ inch of water. Keep the bowl in a sunny area and change the water every day. In a few days, you’ll start to notice sprouts. Plant the sprouted hearts directly in the garden. If you like the taste of baby greens, you can pinch off outer leaves as the lettuce grows. Otherwise, harvest romaine when it’s around 6 to 8 inches tall. If you want to continue growing lettuce, cut the romaine heads off right above the soil line with a sharp knife, leaving the base and root system intact. Otherwise, uproot the whole plant. (Instructions via Lifehacker) 6.Lemongrass
A frequent component of Thai dishes, lemongrass is a great addition to marinades, stir-fries, spice rubs, and curry pastes. To grow your own from scraps, cut off the tops of a bunch of lemongrass and place the stalks in water. Change the water every few days. In approximately two or three weeks, you should see new roots. When the stems have developed strong root growth, plant the stalks in a pot or garden (preferably in an area that receives lots of sun). Because lemongrass needs to stay warm year round, plant the stalks in a container that can be moved inside during the winter months. Harvest lemongrass once it reaches one foot in height; just cut off the amount you need, being careful not to uproot the plant. (Instructions via Suited to the Seasons) 7.Garlic Sprout
While you may not be able to grow garlic bulbs, you can grow garlic sprouts—also known as garlic greens—from a clove or bulb. Place a budding clove (or even a whole bulb) in a small cup, bowl, or jar. Add water until it covers the bottom of the container and touches the bottom of the cloves. Be careful not to submerge the cloves in order to avoid rot. Change the water every other day and place in a sunny area. After a few days, the clove or bulb will start to produce roots. Sprouts may grow as long as 10 inches, but snip off the greens once they’re around 3 inches tall. Just be sure not to remove more than one-third of each sprout at one time. They’re tasty on top of baked potatoes, salads, in dips, or as a simple garnish. (Instructions via Simple Daily Recipes) Hope you can enjoy your harvest!

The carrot (Daucus carota subsp. sativus) is a root vegetable, usually orange in colour, though purple, black, red, white, and yellow cultivars exist.The carrot is a biennial plant in the umbellifer family Apiaceae. At first, it grows a rosette of leaves while building up the enlarged taproot. Fast-growing cultivars mature within three months (90 days) of sowing the seed, while slower-maturing cultivars need a month longer (120 days). The roots contain high quantities of alpha- and beta-carotene, and are a good source of vitamin K and vitamin B6, but the belief that eating carrots improves night vision is a myth put forward by the British in World War II to mislead the enemy about their military capabilities.
*Nutrition Raw carrots are 88% water, 9% carbohydrates, 0.9% protein, 2.8% dietary fiber, 1% ash and 0.2% fat. Carrot dietary fiber comprises mostly cellulose, with smaller proportions of hemicellulose, lignin and starch. Free sugars in carrot include sucrose, glucose, and fructose. The carrot gets its characteristic, bright orange colour from β-carotene, and lesser amounts of α-carotene, γ-carotene, lutein, and zeaxanthin.α- and β-carotenes are partly metabolized into vitamin A, providing more than 100% of the Daily Value (DV) per 100 g serving of carrots (right table). Carrots are also a good source of vitamin K (13% DV) and vitamin B6 (11% DV), but otherwise have modest content of other essential nutrients (table). The provitamin A beta-carotene from carrots does not actually help people to see in the dark unless they suffer from vitamin A deficiency. This myth was propaganda used by the Royal Air Force during the Second World War to explain why their pilots had improved success during night air battles, but was actually used to disguise advances in radar technology and the use of red lights on instrument panels. Nevertheless, the consumption of carrots was advocated in Britain at the time as part of a Dig for Victory campaign. A radio programme called The Kitchen Front encouraged people to grow, store and use carrots in various novel ways, including making carrot jam and Woolton pie, named after the Lord Woolton, the Minister for Food. The British public during WWII generally believed that eating carrots would help them see better at night and in 1942 there was a 100,000-ton surplus of carrots from the extra production.
*How to grow/Tips* Carrots are direct seeded in the garden rather than being transplanted and disturbing the roots. Carrot seeds can take up to 15 days to germinate. Keep the soil moist until seedlings appear. *Soil Choose fertile, loose, neutral or slightly acidic soil, preferably sandy loam, which is good for irrigating and draining. *Temperature he temperature of germination: 20℃-25℃ the growth temperature: 17℃-23℃ *Humidity 70-80% *Sun Exposure Full sun to light shade *Fertilization Potassium sulphate compound fertilizer When to harvest your carrots will depend on the variety you are growing, but the average is about 50 to 75 days from seed.
Hope you will have a good harvest!

Lilies are genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies.
Lilies are tall perennials ranging in height from 2–6 ft (60–180 cm). They form naked or tunicless scaly underground bulbs which are their organs of perennation. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are buried deep in the ground, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at some depth in the soil, and each year the new stem puts out adventitious roots above the bulb as it emerges from the soil. These roots are in addition to the basal roots that develop at the base of the bulb. The flowers are large, often fragrant, and come in a wide range of colors including whites, yellows, oranges, pinks, reds and purples. Markings include spots and brush strokes. The plants are late spring- or summer-flowering. Flowers are borne in racemes or umbels at the tip of the stem, with six tepals spreading or reflexed, to give flowers varying from funnel shape to a "Turk's cap". The tepals are free from each other, and bear a nectary at the base of each flower. The ovary is 'superior', borne above the point of attachment of the anthers. The fruit is a three-celled capsule.
Many species are widely grown in the garden in temperate and sub-tropical regions. They may also be grown as potted plants. Numerous ornamental hybrids have been developed. They can be used in herbaceous borders, woodland and shrub plantings, and as patio plants. Some lilies, especially Lilium longiflorum, form important cut flower crops. These may be forced for particular markets; for instance, Lilium longiflorum for the Easter trade, when it may be called the Easter lily. Lilies are usually planted as bulbs in the dormant season. They are best planted in a south-facing (northern hemisphere), slightly sloping aspect, in sun or part shade, at a depth 2½ times the height of the bulb (except Lilium candidum which should be planted at the surface). Most prefer a porous, loamy soil, and good drainage is essential. Most species bloom in July or August (northern hemisphere). The flowering periods of certain lily species begin in late spring, while others bloom in late summer or early autumn.They have contractile roots which pull the plant down to the correct depth, therefore it is better to plant them too shallowly than too deep. A soil pH of around 6.5 is generally safe. The soil should be well-drained, and plants must be kept watered during the growing season. Some plants have strong wiry stems, but those with heavy flower heads may need staking.

Hi, dear Aries! Aries are born from March 21 to April 19. Represented by the symbol of the ram, Aries are smart, loyal, and impulsive. Their element group is fire, and they share that with Leo and Sagittarius. Aries are very honest and will always be blunt on what is on their mind. Extremely loyal with a fiery temper, Aries will always inform their significant other when they are upset or disagree. Straightforward and brazen, Aries will do everything to go after the one that they want. However, Aries can be Hot-tempered, impatient, impulsive. *Famous Aries* Leonardo da Vinci, Robert Downey Jr., Lady Gaga, Reese Witherspoon. *Flower* Thistle
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the plant – on the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flowerheads. Thistle flowers are the favourite nectar sources of the pearl-bordered fritillary, small pearl-bordered fritillary, high brown fritillary, and dark green fritillary butterflies. Thistles (and thistle-seed feeders) also provide important sustenance for goldfinches and are strongly favored by many butterflies besides fritillaries such as the monarch, skippers, and the tiger swallowtail[disambiguation needed]. Additionally, hummingbirds will feed on the flowers of the biennial species (which feature large flowers, as compared with the perennial Canada thistle). Some thistles (for example Cirsium vulgare, native to Eurasia), have been widely introduced outside their native range. Control measures include Trichosirocalus weevils, but a problem with this approach, at least in North America, is that the introduced weevils may affect native thistles at least as much as the desired targets.

Geranium is a genus of 422 species of flowering annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, but mostly in the eastern part of the Mediterranean region.
The palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring. Geraniums are eaten by the larvae of some Lepidoptera species including brown-tail, ghost moth, and mouse moth. At least several species of Geranium are gynodioecious.The species Geranium viscosissimum (sticky geranium) is considered to be protocarnivorous. The genus name is derived from the Greek γέρανος (géranos) or γερανός (geranós) ‘crane’. The English name ‘cranesbill’ derives from the appearance of the fruit capsule of some of the species. Species in the genus Geranium have a distinctive mechanism for seed dispersal. This consists of a beak-like column which springs open when ripe and casts the seeds some distance. The fruit capsule consists of five cells, each containing one seed, joined to a column produced from the centre of the old flower. The common name ‘cranesbill’ comes from the shape of the unsprung column, which in some species is long and looks like the bill of a crane. However, many species in this genus do not have a long beak-like column.

The garden strawberry (or simply strawberry; Fragaria × ananassa) is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of Fragaria virginiana from eastern North America and Fragaria chiloensis, which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of Fragaria × ananassa have replaced, in commercial production, the woodland strawberry (Fragaria vesca), which was the first strawberry species cultivated in the early 17th century. The strawberry is not, from a botanical point of view, a berry. Technically, it is an aggregate accessory fruit, meaning that the fleshy part is derived not from the plant's ovaries but from the receptacle that holds the ovaries. Each apparent "seed" (achene) on the outside of the fruit is actually one of the ovaries of the flower, with a seed inside it.
*How to grow? 1. DECIDE WHERE TO GROW YOUR STRAWBERRIES Get them some sun on the balcony, rooftop, patio or doorstep. And even if you live in an apartment, condo, townhouse, or small home, you can grow berries in a container on your balcony, rooftop, patio, or even doorstep. If your horizontal space is limited, consider growing strawberries in a hanging basket or stacked planter, which will allow you to take advantage of vertical growing space as the strawberry plants tumble out over the sides. By home-growing your own berries, you will also be helping the environment, since commercially grown strawberries use wasteful amounts of water, chemical fertilizers, and some of the worst pesticides imaginable, not to mention the environmental cost of shipping them for hundreds or thousands of miles. A sunny spot outside your home is the best place to grow strawberries, though you can get a partial crop with less than a half day of direct sunlight. For shadier spots, try planting Alpine strawberries (available from vegetable seed catalogs and online nurseries), which take more patience but ultimately produce delicious fruit. 2. CHOOSE A CONTAINER FOR THEM Give your plants enough room to grow. Whether you choose a container made of clay, plastic, wood, or other material, make sure it has a soil depth of at least 12-14 inches to give the plants’ root systems space to grow. How many plants you can fit in will depend upon the width of the container, since you should space plants about 10-12 inches apart to allow them to spread horizontally.
3. FILL THE CONTAINER WITH SOIL THAT MAKES STRAWBERRIES HAPPY Strawberries like room! Strawberries like deep, loamy soil that drains well. This means that it should contain plenty of organic matter (such as compost, shredded bark or peat moss) as well as some sand or grit. Most potting soil mixes sold at nurseries will be sufficient, and if you have access to compost, sprinkle an inch or so on top. Be sure the container has drainage holes in the bottom. Before planting, buy a small bag of organic fertilizer from your nursery, mix it into your soil, and water this down. You can ask your nursery to recommend the right fertilizer for your soil type and region, but in general, strawberries like plenty of nitrogen plus balanced amounts of the other major nutrients. A 10-10-10 fertilizer is not excessive, especially since organic fertilizers have a slower release time. 4. GET YOUR STRAWBERRY PLANTS Want your strawberries this year, or can you wait? Your next step is to find some plants and put them in the soil. There are two main kinds of strawberries available: “June-bearing” plants that will bear in spring or early summer, and “Everbearing” or day-neutral varieties that can bear from early summer right up until your first frost. While June-bearing varieties can take a year to establish (you normally plant them now for next year’s harvest), everbearing plants can give you fruit the very first year and may allow you to extend your harvest over a period of weeks or months. There are many great varieties of strawberries out there and your local nursery should be able to recommend some good ones for the climate in your area. Sequoia and Chandler are the two sweetest berries I have ever tasted, while Seascape, Honeoye, Quinalt, Tristar, and Allstar have proven themselves in multiple climates. 5. CARE FOR YOUR PLANTS AND ENJOY For optimum production, keep your strawberry plants well watered throughout the growing season. Plants should continue to be productive for at least 2-3 years, but will need to be replaced thereafter. To renovate June-bearing plants for next year, trim off their old leaves, making sure not to damage the center stalk (crown) of the plant. Everbearers do not need this trimming, but all plants should be given some top-dressed fertilizer again after fruiting. I wish you the best of success in growing your own berries! R.J.

Tulips (Tulipa) form a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly colored, generally red, pink, yellow, or white (usually in warm colors). They often have a different colored blotch at the base of the tepals (petals and sepals, collectively), internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to Amana, Erythronium and Gagea in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble. Tulips originally were found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalised and cultivated (see map). In their natural state they are adapted to steppes and mountainous areas with temperate climates. Flowering in the spring, they become dormant in the summer once the flowers and leaves die back, emerging above ground as a shoot from the underground bulb in early spring.
While tulips had probably been cultivated in Persia from the tenth century, they did not come to the attention of the West until the sixteenth century, when Western diplomats to the Ottoman court observed and reported on them. They were rapidly introduced into Europe and became a frenzied commodity during Tulip mania. Tulips were frequently depicted in Dutch Golden Age paintings, and have become associated with the Netherlands, the major producer for world markets, ever since. In the seventeenth century Netherlands, during the time of the Tulip mania, an infection of tulip bulbs by the tulip breaking virus created variegated patterns in the tulip flowers that were much admired and valued. While truly broken tulips do not exist anymore, the closest available specimens today are part of the group known as the Rembrandts – so named because Rembrandt painted some of the most admired breaks of his time. Breeding programs have produced thousands of hybrid and cultivars in addition to the original species (known in horticulture as botanical tulips). They are popular throughout the world, both as ornamental garden plants and as cut flowers.
Tulips are mainly distributed along a band corresponding to Latitude 40o north, from south-east of Europe (Ukraine, Russia) and Turkey in the west, through the Levant (Syria, Israel, Palestinian Territories, Lebanon and Jordan) and the Sinai Peninsula. From there it extends eastwards through Jerevan, (Armenia) and Baku (Azerbaijan) and on the eastern shore of the Caspian Sea through Turkmenistan, Bukhara, Samarkand and Tashkent (Uzbekistan), to the eastern end of the range in the Pamir-Alai and Tien-Shan mountains in Central Asia, which form the centre of diversity. Further to the east, Tulipa is found in the western Himalayas, southern Siberia, Inner Mongolia, and as far as the northwest of China. While authorities have stated that no tulips west of the Balkans are native, subsequent identification of Tulipa sylvestris subsp. australis as a native of the Iberian peninsula and adjacent North Africa shows that this may be a simplification. In addition to these regions in the west tulips have been identified in Greece, Cyprus and the Balkans. In the south, Iran marks its furthest extent, while the northern limit is the Ukraine. Although tulips are also throughout most of the Mediterranean and Europe, these regions do not form part of the natural distribution. Tulips were brought to Europe by travellers and merchants from Anatolia and Central Asia for cultivation, from where they escaped and naturalised (see map). For instance, less than half of those species found in Turkey are actually native. These have been referred to as neo-tulipae. Tulips are indigenous to mountainous areas with temperate climates, where they are a common element of steppe and winter-rain Mediterranean vegetation. They thrive in climates with long, cool springs and dry summers. Tulips are most commonly found in meadows, steppes and chaparral, but also introduced in fields, orchards, roadsides and abandoned gardens.

What is COVID-19? Accordinng to WHO, Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). Coronavirus disease (COVID-19) is a new strain that was discovered in 2019 and has not been previously identified in humans. Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans. Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing. Some advice to strengthen your personal protection: 1. Avoid going to crowded places. 2. Wear a mask, and throw it (after disinfecting it) before you enter into your house. 3. Wash hands frequently, wash for more than 30 seconds at a time (you can sing a Happy Birthday Song while washing) 4. Cover your nose and mouth with your elbow when you sneeze, remember with the ELBOW. 5. Do exercise, reasonable diet, working and resting regularly and keeping happy mood.
