It is generally accepted that flowers have a positive influence on people. There are good reasons why people bring flowers to the sick in order to raise their spirits, or give them as gifts for special occasions, such as birthdays, anniversaries, and other celebrations. Flowers create a pleasant atmosphere not just in the home; they are also used in business environments to create a positive ambience. Up until now, however, there has been virtually no research into the positive affects of flowers.
Dutch researchers took up the challenge. Using a pretence in order to disguise the real purpose of the study, they invited 64 test subjects to a lunch. The subjects were divided into a total of four rooms. The rooms were identical except for the flower decorations. The behaviour of the test subjects was recorded by cameras. After the meal the project leader showed the test subjects photos and asked them to evaluate the characteristics of the people in the photos. This is an established technique that reliably tracks the emotional state of the person evaluating the photo.
A week later the participants came back for a second test. This time the subjects had to complete a memory test: among other things, they were asked to give their general impression of their experience at the first test session, and describe the test room’s features. They were also asked which flowers they thought worked best in particular situations and environs. Finally, 16 subjects were interviewed in depth. They were asked how they had perceived flowers in a variety of situations in which they had been aware that flowers were a part of the surroundings.
Influence on an unconcius level
The experiments showed that at an unconscious level, flowers have a positive influence on the way restaurant-goers perceive each other as well as how enjoyable they remember the restaurant experience to be. People are perceived to be more cheerful, warmer, more enjoyable and accessible in rooms with flower arrangements. They are also perceived as less arrogant, tense, egocentric, shy, suspicious, and moody than when encountered in a room without flowers. When they are in rooms with flowers, people have more of a feeling of well-being than when they are in rooms without flowers. Fresh, well-kept flowers in a restaurant give the impression that the proprietor is taking good care of his guests. However, badly cared-for, wilted flowers will cause the guest to question the restaurant’s quality. Project leader Dr. Jozina Mojet comments that, “Well-cared for vase flowers are an easy but effective way to improve a restaurant’s image.”
This also goes for such business environs as banks and hotel lobbies. It is not the case for train stations and airports which were judged by those questioned as “completely unsuitable for cut flower arrangements”, says the researcher.
This plant has long, cascading stems covered in tiny white flowers. Great in hanging baskets and decorative containers where its pretty trailing habit can be shown off.
Keep it evenly watered for continuous bloom.
Ipomoea pes-caprae, also known as Beach Morning Glory or Goat’s Foot, is a common pantropical creeping vine belonging to the family Convolvulaceae. It grows on the upper parts of beaches and endures salted air. It is one of the most common and most widely distributed salt tolerant plants and provides one of the best known examples of oceanic dispersal. Its seeds float and are unaffected by salt water.
Originally described by Linnaeus, it was placed in its current genus by Robert Brown in 1818.
Bougainvillea (/ˌbuːɡɨnˈvɪliə/ or /ˌboʊɡɨnˈvɪliə/) is a genus of thorny ornamental vines, bushes, and trees with flower-like spring leaves near its flowers. Different authors accept between four and 18 species in the genus. They are native plants of South America from Brazil west to Perú and south to southern Argentina (Chubut Province). Bougainvillea are also known as buganvilla (Spain), bugambilia (Mexico), Napoleón (Honduras), veranera (Colombia, Nicaragua, El Salvador, Costa Rica and Panama), trinitaria (Colombia, Cuba, Panama, Puerto Rico, Dominican Republic & Venezuela), Santa Rita (Argentina, Bolivia, Brazil, Paraguay and Uruguay), bonggavilla (Philippines) or papelillo (northern Peru).
Specimen plant. Sky blue flowers looking like butterflies – unusual color for tropics. Clerodendrum ugandense has been cultivated in botanical gardens for almost 100 years, but has only recently been considered as flowering potplant. It is a fast growing plant which in nature grows to 6-9 ft, but is easily kept much smaller. The irregular flowers are bright blue, in two different shades of blue and are produced more or less continuously throughout the summer and fall. Flowers have long purple anthers which bend elegantly upwards.
Grow this clerodendrum in partial shade. Water freely in growth but reduce watering in winter. Hardiness: USDA Zones 10 – 11. Performs best in a frostfree climate, but it is root hardy in zones 8 and 9, freezing to the ground in winter, but returning from its roots in spring.
Prune back as needed to keep it in bushy shape. Cut back the old wood to a pair of buds to improve flowering. In areas that get frost, you can get the most consistent flowering by growing it in a large pot that can be brought indoors when temperatures approach freezing.
It has an odd scent when the leaves are brushed which may serve to repel chewing insects because it is pest free.
The genus Lobelia comprises a substantial number of large and small annual, perennial and shrubby species, hardy and tender, from a variety of habitats, in a range of colours. Many species appear totally dissimilar from each other. However, all have simple, alternate leaves and 2-lipped tubular flowers, each with 5 lobes. The upper two lobes may be erect, while the lower three lobes may be fanned out. Flowering is often abundant and the flower colour intense, hence their popularity as ornamental garden subjects.
Unlike regular potatoes, which grow best when the soil is cool, sweet potatoes like it hot! They are tropical plants that are very sensitive to cold weather. In warm climates, many gardeners plant sweet potatoes about a month after the last spring frost, when both the air and soil are dependably warm. The plants produce lush vines that make a pretty ground cover, so they are a great crop for beds that adjoin areas that are difficult or tiresome to mow.
Nerium oleander /ˈnɪəriəm ˈoʊliː.ændər/(Tamil:அறளி பூ/Alari pū) is an evergreen shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as oleander, from its superficial resemblance to the unrelated olive Olea.[Note 1] It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name oualilt for the flower. Oleander is one of the most poisonous of commonly grown garden plants.
Trachelospermum jasminoides is commonly grown as an ornamental plant and houseplant. In gardens, public landscapes, and parks it is used as a climbing vine, a groundcover, and a fragrant potted plant on terraces and patios. It will flower in full sun, partial shade, or total shade, and requires well-drained soil (if constantly kept damp it may succumb to fungal infection), moderate water, moderate fertilizer, and a climbing structure (whether a trellis or another plant is secondary). Propagation is most commonly done with cuttings/ clones.
It is widely planted in California and also particularly in the Southeastern United States, where its hardiness, confined to USDA Zones 8-10, the area of the former Confederate States of America, gives it the name confederate jasmine. It gets another of its common names, trader’s compass, from an old Uzbekistan saying that it pointed traders in the right direction, provided they were of good character. It is also called star jasmine in Europe and Chinese jasmine or Chinese ivy in Asia.
Lamprocapnos spectabilis (bleeding heart) is a species of flowering plant in the poppy family Papaveraceae, native to Siberia, northern China, Korea and Japan. It is the sole species in the monotypic genus Lamprocapnos, but is still widely referenced under its old name Dicentra spectabilis (now listed as a synonym). It is valued in gardens and in floristry for its heart-shaped pink and white flowers, borne in spring.
Other common names include “Dutchman’s breeches”, “lyre flower” and “lady-in-a-bath”.
Delonix regia is a species of flowering plant in the family Fabaceae, subfamily Caesalpinioideae. It is noted for its fern-like leaves and flamboyant display of flowers. In many tropical parts of the world it is grown as an ornamental tree and in English it is given the name Royal Poinciana or Flamboyant. It is also one of several trees known as Flame tree.
In Nepal,India and Pakistan it is known as Gulmohar گل مور or گلمور in Hindi and Urdu. In Persian “gul” means “flower”, and “mohr” means “coin” or “stamp”. Also “mor” means “peacock”, which seems to be most close to physical appearance and beauty of this tree. It is also known there as Krishnachura or Krusnachuda (Bengali/Oriya: crown of the Krishna) and Krishnasura (in Assamese and Bengali). In Kerala, it is known as Kaalvaripoo (കാൽവരിപ്പൂവ്). In Vietnam, it is known as Phượng vĩ (means “Phoenix’s Tail) (Vietnamese), Malinche, and Tabachine. In Guatemala, Antigua Guatemala, it is known as Llama del Bosque and in Paraguay as Chivato. In Khmer, the tree and the flower is known collectively as “Peacock” or ដើម (tree) or ផ្កា (flower) «ក្ងោក»។ .
Lagerstroemia /ˌleɪɡərˈstriːmiə/, commonly known as crape myrtle or crepe myrtle, is a genus of around 50 species of deciduous and evergreen trees and shrubs native to the Indian Subcontinent, southeast Asia, northern Australia, and parts of Oceania, cultivated in warmer climates around the world. It is a member of the Lythraceae, which are also known as the loosestrife family. The genus is named after the Swedish merchant Magnus von Lagerström, who supplied Carolus Linnaeus with plants he collected. These flowering trees are beautifully colored and are often planted both privately and commercially. Popular cultivars used in modern landscaping include the bright red ‘Dynamite’, the deep pink ‘Pink Velour’, and the purple ‘Twilight’ crape myrtle, which also has a bark that changes colors.
Indian hawthorn (Rhaphiolepsis indica) is a small, slow-growing shrub perfect for sunny locations. It’s easy to care for because it keeps a neat, rounded shape naturally, without the need for pruning. The shrub looks great year round and becomes a focal point in spring when large, loose clusters of fragrant, pink or white flowers bloom. The flowers are followed by small blue berries that attract wildlife. Read on to find out how to grow Indian hawthorn.
A member of the Verbena family, Queen’s Wreath is a breathtaking vine native to Mexico and Central America. It is a large twining vine with long clusters of star-like flowers. The white flowered variety is rather rare compared to the purple. This tropical, non-aggressive vine is ideal for warm humid climates where it can reach over 30 feet, but it can be container grown in colder climates and will remain somewhat smaller. 10+ Seeds.
Brugmansia is a genus of seven species of flowering plants in the family Solanaceae. Their large, fragrant flowers give them their common name of angel’s trumpets, a name sometimes used for the closely related genus Datura. Brugmansia are woody trees or shrubs, with pendulous, not erect, flowers, that have no spines on their fruit. Datura species are herbaceous bushes with erect (not pendulous) flowers, and most have spines on their fruit
Allamanda is a genus of tropical plants native to Central and South America. These plants characteristically grow as vines or shrubs and are very rapid growers in environments they like. They are grown as ornamentals in tropical gardens all over the world and can also be cultivated in greenhouses. Gardeners interested in growing Allamanda should be aware that these plants are poisonous, producing a sticky sap known to be a skin and eye irritant.
They have mostly broad, relatively flat leaves. Inflorescences form in a shallow depression the center of the plant, which often fills partway with water, through which the flowers bloom. Offsets form around the central flowering rosette. The leaves immediately surrounding the inflorescence are very often brightly colored, and many species show banding or striping on most or all of their leaves. Neoregelia Bromeliads are excellent plants and will adapt to many conditions, so in a warm setting they can be used as a indoor plant or outdoor landscape plant. Neoregelia Bromeliads are some of the most colorful epiphytes around. Neoregelia Bromeliads range from the common house plant varieties to the more rare exotic varieties such as the Neoregelia ‘Rafael’ Bromeliad.
Aechmea blanchetiana is a bromeliad typical of Atlantic Coast restingas vegetation which is an ecosystem of Atlantic Forest biome of eastern Brazil. This plant grows from the State of Bahia south to Espírito Santo. It it is often grown elsewhere as an ornamental plant.
