The Syrian Arab Republic General Establishment of Posts has issued the flower stamp series in related with the Damascus International Flower Fair 2011 on June 22, 2011. The issue stamps consist of 5 single stamps depicted the well known flower such as: Nerium Oleander, Lily of the Valley, Lotus, The Bird of Paradise, and Dahlia.
Nerium Oleander
Nerium oleander is an evergreen shrub or small tree, as the only species currently classified in the genus Nerium of the family Apocynaceae. This small tree have toxic in all its parts. It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. Nerium Oleander is one of the most poisonous of commonly grown garden plants.
Nerium Oleander grows to 2–6 m tall, with erect stems that splay outward as they mature; first-year stems have a glaucous bloom, while mature stems have a grayish bark. The leaves are in pairs or whorls of three, thick and leathery, dark-green, narrow lanceolate. The flowers grow in clusters at the end of each branch; they are white, pink to red, 2.5–5 cm diameter, with a deeply 5-lobed fringed corolla round the central corolla tube.
Nerium Oleander grows well in warm subtropical regions, where it is extensively used as an ornamental plant in landscapes, in parks, and along roadsides. It is drought-tolerant and will tolerate occasional light frost down to −10 °C (14 °F). It is tolerant of poor soils and drought.
Lily of the Valley
Convallaria majalis commonly known as the Lily of the Valley, is a poisonous woodland flowering plant native throughout the cool temperate Northern Hemisphere in Asia, Europe and in the southern Appalachian Mountains in the United States. It is possibly the only species in the genus Convallaria.
Convallaria majalis is a popular garden plant, as a herbaceous perennial plant that forms extensive colonies by spreading underground stems called rhizomes, grown for its scented flowers and for its ground-covering abilities in shady locations.
The stems grow to 15–30 cm tall, with one or two leaves 10–25 cm long, flowering stems have two leaves and a raceme of 5–15 flowers on the stem apex. The flowers are white tepals (rarely pink), bell-shaped, 5–10 mm diameter, and sweetly scented; flowering is in late spring.
Various kinds and cultivars are grown, including those with double flowers, rose-colored flowers, variegated foliage and ones that grow larger than the typical species.
Lotus
Nymphaea lotus, the Tiger Lotus, White lotus or Egyptian White Water-lily, is a flowering plant of the family Nymphaeaceae. It grows in various parts of East Africa and Southeast Asia.
This species of water lily has lily pads which float on the water, and blossoms which rise above the water. It is a perennial, grows to 45 cm in height, and prefers clear, warm, still and slightly acidic waters. The color of the flower is white and sometimes tinged with pink.
Nymphaea lotus is often used as an aquarium plant. Sometimes it is grown for its flowers, while other aquarists prefer to trim the lily pads, and just have the underwater foliage. It was introduced into western cultivation in 1802 by Loddiges Nursery.The ancient Egyptians cultivated the white lotus in ponds and marshes. This flower often appears in ancient Egyptian decorations.
Bird of Paradise
Heliconia, is a monophyletic genus of about 100-200 species of flowering plants native to the tropical Americas and the Pacific Ocean islands west to Indonesia. Many species of Heliconia are found in rainforests or tropical wet forests of these regions. Common names for the genus include lobster-claws, wild plantains or false bird-of-paradise. The last term refers to their close similarity to the bird-of-paradise flowers (Strelitzia). Collectively, these plants are also simply referred to as heliconias.
Heliconias are grown for the florist's trade and as landscape plants. These plants do not grow well in cold, dry conditions. They are very drought intolerant, but can endure some soil flooding. Heliconias need an abundance of water, sunlight, and soils that are rich in humus in order to grow well. These flowers are grown in tropical regions all over the world as ornamental plants (Ong, 2007).
The flower of Heliconia psittacorum (Parrot Heliconia) is especially distinctive, its greenish-yellow flowers with black spots and red bracts reminding of the bright plumage of parrots. The flowers can be hues of reds, oranges, yellows, and greens, and are subtended by brightly colored bracts. The plants typically flower during the wet season.
.
Dahlia
Dahlia is a genus of bushy, tuberous, herbaceous perennial plants native to Mexico, Central America, and Colombia. Dahlia is a member of the Asteraceae or Compositae, dicotyledonous plants, related species include the sunflower, daisy, chrysanthemum and zinnia. There are at least 36 species of dahlia, with hybrids commonly grown as garden plants. The dahlia was declared the national flower of Mexico in 1963.
Flower forms are variable, with one head per stem; these can be as small as 2 in diameter or up to 1 ft .The stems are leafy, ranging in height from as low as 12 in to more than 6–8 ft . The majority of species do not produce scented flowers or cultivars. Like most plants that do not attract pollinating insects through scent, they are brightly colored, displaying most hues, with the exception of blue.
