Asplenium Nidus
Asplenium nidus is an epiphytic species of fern in the family Aspleniaceae, native to tropical southeastern Asia, eastern Australia, Polynesia, Christmas Island, India, and eastern Africa. It is known by the common names bird's-nest fern.Asplenium nidus forms large simple fronds visually similar to banana leaves, with the fronds growing to 50–150 centimetres (20–59 in) long and 10–20 centimetres (3.9–7.9 in) broad. They are light green, often crinkled, with a black midrib, and exhibit circinate vernation. Spores develop in sori on the underside of the fronds. These sori form long rows extending out from the midrib on the back of the outer part of the lamina (frond). The fronds roll back as they brown and create a massive leaf nest in the branches and trunks of trees.
Petunia
Petunia (Petunia x hybrida) is a member of the Solanaceae family (the family of tomato, potato, daturas, and many other species). Although some petunias, in general, can be perennial, the hybrids that are produced and commonly sold nowadays are mostly annual plants.We can find petunias in many different types, heights, and colors, depending on the variety of the plant. For instance, single or double blooming petunias, single colored, linear or splashing color figures. Among the wide color variety, we can see red, white, pink, purple, light blue, yellow and almost all existing colors. Black colored petunia petals are something worth seeing.
Petunia is a famous flower due to its beautiful multi-colored trumpet-shaped flowers. Its foliage is hairy and branching. The plant prefers sunny areas to grow. This is why it is so famous in the United States and all the Mediterranean countries. Its blooming lasts from spring to autumn and its flowers are of the most commonly recognizable flowers all over the world.
Chrysanthemum
Wild Chrysanthemum taxa are herbaceous perennial plants or subshrubs. They have alternately arranged leaves divided into leaflets with toothed or occasionally smooth edges. The compound inflorescence is an array of several flower heads, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of ray florets is white, yellow, or red; many horticultural specimens have been bred to bear many rows of ray florets in a great variety of colors. The disc florets of wild taxa are yellow. Pollen grains are appropriately 34 microns. The fruit is a ribbed achene.Chrysanthemums start bloomingearly in the autumn. This is also known as the favorite flower for the month of NovembeR .Pyrethrum (Chrysanthemum [or Tanacetum] cinerariaefolium) is economically important as a natural source of insecticide. The flowers are pulverized, and the active components, called pyrethrins, which occur in the achenes, are extracted and sold in the form of an oleoresin. This is applied as a suspension in water or oil, or as a powder. Pyrethrins attack the nervous systems of all insects, and inhibit female mosquitoes from biting. In sublethal doses, they have an insect-repellent effecT.They are harmful to fish, but are far less toxic to mammals and birds than many synthetic insecticides. They are not persistent, being biodegradable, and also decompose easily on exposure to light. Pyrethroids such as permethrin are synthetic insecticides based on natural pyrethrum. Despite this, chrysanthemum leaves are still a major host for destructive pests, such as leafminer flies including L. trifolii.Persian powder is an example of industrial product of chrysanthemum insecticide.
MASS CANE
Dracaena fragrans (cornstalk dracaena), is a flowering plant species that is native throughout tropical Africa, from Sudan south to Mozambique, west to Côte d'Ivoire and southwest to Angola, growing in upland regions at 600–2,250 m (1,970–7,380 ft) altitude. It is also known as striped dracaena, compact dracaena, and corn plantDracaena fragrans is a slow growing shrub, usually multistemmed at the base, mature specimens reaching 15 m (49 ft) or more tall with a narrow crown of usually slender erect branches. Stems may reach up to 30 cm (12 in) diameter on old plants; in forest habitats they may become horizontal with erect side branches. Young plants have a single unbranched stem with a rosette of leaves until the growing tip flowers or is damaged, after which it branches, producing two or more new stems; thereafter, branching increases with subsequent flowering episodes.
The leaves are glossy green, lanceolate, 20–150 cm (7.9–59.1 in) long and 2–12 cm (0.79–4.72 in) wide; small leaves are erect to spreading, and larger leaves usually drooping under their weight. The flowers are produced in panicles 15–160 cm (5.9–63.0 in) long, the individual flowers are 2.5 cm (0.98 in) diameter, with a six-lobed corolla, pink at first, opening white with a fine red or purple central line on each of the 7–12 mm (0.28–0.47 in) lobes; they are highly fragrant, and popular with pollinating insects. The fruit is an orange-red berry 1–2 cm (0.39–0.79 in) diameter, containing several seeds
