Indoor Plants Or Houseplants
Visit us on the Web: www.gardeninghelp.org Indoor Plants or Houseplants Over the past twenty years houseplants have grown in popularity. Offered in a wide variety of sizes, shapes, colors and textures, houseplants beautify our homes and help soften our environment. They have been scientifically proven to improve our health by lowering blood pressure and removing pollutants from the air we breathe. When selecting a houseplant, choose reputable suppliers who specialize in growing houseplants. Get off to a good start by thoroughly examining each plant. Watch for brown edges and spindly growth with elongated stems and large gaps between new leaves. Inspect leaves and stem junctions for signs of insect or disease problems. Check any support stakes to make sure they are not hiding broken stems or branches. Finally, make sure the plant is placed in an area that suits its optimal requirements for light, temperature and humidity. Where to Place Your House Plants With the exception of the very darkest areas, you can always find a houseplant with growth requirements to match the environmental conditions in your home. The most important factors are light intensity and duration. The best way to determine the intensity of light at a window exposure area is to measure it with a light meter. A light meter measures light in units called foot-candles. One foot-candle is the amount of light from a candle spread over a square foot of surface area. Plants that prefer low light may produce dull, lifeless-looking leaves when exposed to bright light. Bright light can also cause leaf spots or brown-tipped scorched margins. -
Aiphanes Grandis Borchs
Palm Conservation – Palm Specialist Group Aiphanes grandis Borchs. & Balslev Status: Endangered (EN) Common name None recorded Natural range Aiphanes grandis is endemic to the western slopes of the Andes mountains in Ecuador, at elevations between 1000 and 2000 m. It occurs in cloud forest in the central and southern parts of the country. Recognition characteristics It is a large, solitary palm tree, with a stem up to 20 m tall and 10–20 cm in diameter. The stem and leaves are fiercely armed with long, black spines. The leaf blade is 200–250 cm long with up to 50 leaflets on each side, briefly jagged at apex, inserted in groups and pointing in different directions. The inflorescence is 1–1.5 m long, with up to 200 spreading branches. Flowers are white to pale yellow and fruits 2–3 cm in diameter, dull green and covered with brown, loosely attached bristles. The combination of jagged leaflets and large size distinguishes the species from all other South American palms. Natural history Little is known about the natural history of the species. The palm heart is edible, and its seeds are sometimes pureed and cooked with crude cane sugar to form a nougat-like paste. Threats to survival The estimated loss of potential habitat for A. grandis, based on habitat modeling, is 62%, most of which has occurred over the last 30–40 years. The west Andean mountain forest in southern and central Ecudor, where A. grandis occurs, harbors a high number of endemic plant species. It is also the home to remnant populations of such conspicuous palm species as Ceroxylon ventricosum and C. -
Chapter 6 Care and Handling
Chapter 6 Care and Handling The following TEKS will be addressed in this chapter: (6) The student knows the management factors of floral enterprises. The student is expected to: (A) use temperature, preservatives, and cutting techniques to increase keeping quality; (B) identify tools, chemicals, and equipment used in floral design; (C) fertilize, prune, and water tropical plants; (D) manage pests; and (E) demonstrate the technical skills for increasing the preservation of cut flowers and foliage. Care and Handling of Cut Flowers and Foliages Cut flowers, even though they have been separated from the parent plant, are living, actively metabolizing plant parts. These parts undergo the same basic aging process as the entire plant — only quicker. However, the rate of deterioration can be slowed down considerably by supplying the cut flower with its basic needs. The first and foremost need of a cut flower is water. Second is food. In addition, certain damaging factors such as exposure to ethylene gas, microbial attack and rough handling must be avoided. From a practical point of view, a controlled rate of opening is needed as well as maintenance of good color. All of these factors must be considered by everyone who handles the product. This includes growers wholesalers and retailers. In order to be competitive in the marketplace our product must be desirable to the consumer. Our flowers must be fresh for the customer to enjoy! Factors Affecting Quality There are several factors which play a part in keeping the quality of cut flowers at a high level: (1) the grower (2) moisture balance. -

A Review of Alocasia (Araceae: Colocasieae) for Thailand Including a Novel Species and New Species Records from South-West Thailand
THAI FOR. BULL. (BOT.) 36: 1–17. 2008. A review of Alocasia (Araceae: Colocasieae) for Thailand including a novel species and new species records from South-West Thailand PETER C. BOYCE* ABSTRACT. A review of Alocasia in Thailand is presented. One new species (A. hypoleuca) and three new records (A. acuminata, A. hypnosa & A. perakensis) are reported. A key to Alocasia in Thailand is presented and the new species is illustrated. INTRODUCTION Alocasia is a genus of in excess of 100 species of herbaceous, laticiferous, diminutive to gigantic, usually robust herbs. The genus has recently been revised for New Guinea (Hay, 1990), Australasia (Hay & Wise, 1991), West Malesia and Sulawesi (Hay, 1998), the Philippines (Hay, 1999) while post main-treatment novelties have been described for New Guinea (Hay, 1994) Borneo (Hay, Boyce & Wong, 1997; Hay, 2000; Boyce, 2007) & Sulawesi (Yuzammi & Hay, 1998). Currently the genus is least well understood in the trans-Himalaya (NE India to SW China) including the northern parts of Burma, Thailand, Lao PDR and Vietnam with only the flora of Bhutan (Noltie, 1994) partly covering this range. In the absence of extensive fieldwork the account presented here for Thailand can at best be regarded as provisional. STRUCTURE & TERMINOLOGY Alocasia plants are often complex in vegetative and floral structure and some notes on their morphology (based here substantially on Hay, 1998) are useful to aid identification. The stem of Alocasia, typically of most Araceae, is a physiognomically unbranched sympodium. The number of foliage leaves per module is variable between and within species and individuals, but during flowering episodes in some species it may be reduced to one. -

Anthurium Andraeanum) As a Cut Flower in Bangladesh
Journal of Bangladesh Academy of Sciences, Vol. 37, No. 1, 103-107, 2013 VARIETAL STUDY OF ANTHURIUM (ANTHURIUM ANDRAEANUM) AS A CUT FLOWER IN BANGLADESH M.S. ISLAM, H. MEHRAJ, M.Z.K. RONI, S. SHAHRIN AND A.F.M. JAMAL UDDIN* Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh ABSTRACT Five varieties viz., Caesar, Aymara, Ivory, Jewel, and Triticaca were in use for the study in Randomized Complete Block Design with five replications. Significant differences among cultivars were noted for all attributes evaluated. Variety ‘Triticaca’ had maximum stalk length and diameter, spathe length and breadth, spadix length, vase life and flowers per plant. Through present analysis it is noticed that, variety ‘Titicaca’ are exceedingly preferred because of its attractive flowers, excellent flower size, yield potentiality and long shelf life. Key words: Anthurium, Cut flower, Vase life INTRODUCTION Anthurium (Anthurium andraeanum) is a slow-growing perennial flowering plant that requires shady, humid conditions as found in tropical forests. The genus anthurium is evergreen and belongs to the family Araceae as the plant possesses an underground rhizome with adventitious roots, characteristic of the family. Anthurium characteristically produces numerous inflorescences subtended by brightly colored spathes, which are carried on long, slender peduncles. Spathes are characteristically heart-shaped, flat, puckered and shiny and flowers have a wide range of spathe colors viz., white, pink, salmon-pink, red, light-red, dark-red, brown, green, lavender, cream or multi-colored. The colorful spathe is long-lasting. However, the ‘true’ flowers are found on the spadix and have large numbers of pistils, each surrounded by four stamens.
