  • 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.

Received: 18 May 2020; Accepted: 2 June 2020; Published: 3 June 2020 Abstract: The genera Dracaena and Sansevieria (Asparagaceae, Nolinoideae) are still poorly resolved phylogenetically. Plants of these genera are commonly distributed in Africa, China, Southeast Asia, and America. Most of them are cultivated for ornamental and medicinal purposes and are used in various traditional medicines due to the wide range of ethnopharmacological properties. Extensive in vivo and in vitro tests have been carried out to prove the ethnopharmacological claims and other bioactivities. These investigations have been accompanied by the isolation and identification of hundreds of phytochemical constituents. The most characteristic metabolites are steroids, flavonoids, stilbenes, and saponins; many of them exhibit potent analgesic, anti-inflammatory, antimicrobial, antioxidant, antiproliferative, and cytotoxic activities. This review highlights the structures and bioactivities of flavonoids and stilbenoids isolated from Dracaena and Sansevieria. Keywords: Dracaena; Sansevieria; biological/pharmacological activities; flavonoids; stilbenoids 1. Introduction The taxonomic boundaries of the dracaenoid genera Dracaena and Sansevieria have long been debated.

  • CORN PLANT Dracena Fragrans Characteristics Culture Noteworthy
    CORN PLANT Dracena fragrans Characteristics House Plant Water: Medium Zone: 10 to 12 Maintenance: Low Height: 15.00 to 50.00 feet Flower: Showy, Fragrant Spread: 3.00 to 10.00 feet Leaf: Evergreen Bloom Time: Seasonal bloomer Fruit: Showy Bloom Description: White-yellow Tolerate: Drought Sun: Part shade Culture Easily grown in containers as an indoor foliage plant where it typically thrives in organically rich, consistently moist, well-drained soils in part shade. Use a loamy, peaty, well-drained potting soil. Corn plant is best sited in bright indirect light locations protected from significant periods of direct sun and drafts. Tolerates some low light. Containers may be placed on beds of wet pebbles with regular misting of plant leaves in order to increase humidity. Dry soils usually result in brown leaf tips. Too much sun may prevent best foliage color from developing. Keep soils uniformly moist during the growing season, but reduce watering from fall to late winter. Allow soils to dry slightly between waterings, but never allow the soils to totally dry out. Plants tolerate a wide range of indoor temperatures, but are best grown in temperatures of 60-75 degrees F. Plant containers may be placed outdoors in summer but should always be brought back indoors in early fall before outdoor temperatures begin to dip below 50 degrees F. This is a frost-free tropical perennial. Noteworthy Characteristics Dracaena fragrans, commonly known as corn plant, is a popular, durable, easy-to-grow indoor houseplant Although it may soar to 20’ tall or more in its native habitat, it more often is seen in the 4-6’ tall range as a container plant in the U.S.

Box 5411, Maalla, Aden, Yemen; [email protected] Received: 28 September 2018; Accepted: 24 October 2018; Published: 26 October 2018 Abstract: Dracaena cinnabari Balf. f. (Dracaenaceae) is an important plant endemic to Soqotra Island, Yemen. Dragon’s blood (Dam Alakhwin) is the resin that exudes from the plant stem. The ethnobotanical survey was carried out by semi-structured questionnaires and open interviews to document the ethnobotanical data of the plant. According to the collected ethnobotanical data, the resin of D. cinnabari is widely used in the traditional folk medicine in Soqotra for treatment of dermal, dental, eye and gastrointestinal diseases in humans. The resin samples found on the local Yemeni markets were partly or totally substituted by different adulterants. Organoleptic properties, solubility and extractive value were demonstrated as preliminary methods to identify the authentic pure Soqotri resin as well as the adulterants. In addition, the resin extracts and its solution in methanol were investigated for their in vitro antifungal activities against six human pathogenic fungal strains by the agar diffusion method, for antioxidant activities using the DPPH assay and for cytotoxic activity using the neutral red uptake assay. The crude authentic resin dissolves completely in methanol. In comparison with different resin extracts, the methanolic solution of the whole resin showed the strongest biological activities. It showed strong antifungal activity, especially against Microsporum gypseum and Trichophyton mentagrophytes besides antioxidant activities and toxicity against FL-cells.

This evergreen species is named after its dark red resin, which is known as "dragon's blood". Its leaves are found only at the end of its youngest branches; its leaves are all shed every 3 or 4 years before new leaves simultaneously mature. Branching tends to occur when the growth of the terminal bud is stopped, due to either flowering or traumatic events (e.g. herbivory). The trees can be harvested for their crimson red resin, called dragon's blood, which was highly prized in the ancient world and is still used today. Dragon's blood is used as a stimulant and abortifacient. The root yields a gum-resin, used in gargle water as a stimulant, astringent and in toothpaste. The root is used in rheumatism, the leaves are a carminative.
