Venus Flytrap – Feed On Insects




Venus flytrap is known as Dionaea muscipula. It belongs to the kingdom - plantae, phylum – anthophyta, class – magnoliospdia, order – nepenthales  and family – droseraceae. This is one kind of interesting plant which feed on insects. Venus flytrap is the carnivorous plant. Initially scientist believed this plant to be a myth until they found the physical proof for the existence of such a plant. The plant is innocuous looking rosette. The leaf blades terminate in distinctive bivalve traps with sharply toothed edges. The length of the leaf blade is up to 12cm whereas the trap length is upto 4 cm. the trap of venus flytrap is very powerful as the  ones set by  trappers for wolves, bears etc. it is effective in catching its own small preys.

 The leaves of the venus  flytrap is open wide  and contain stiff hairs on them called trigger or sensitive hairs. The sensitive hairs at  fold of the leaf prevent them from closing every time when a drop of rain falls on it because the leave requires two or more of these hairs triggered in succession. Like other plants venus flytraps gather nutrients form gases in the air and nutrients in the soil. However they live healthier if they get nutrients from insects. Insects are attracted to the small traps. On the inner lobes there are  usually three trigger hair and if an insect lands on lobe and brushes against two of these hairs the trap with snap partially shut  with a speed that amazes onlookers. The teeth are now interlocked preventing larger prey from escaping .  The trap need to close further to produce tight seal for the prey  to be digested.

The outside of the trap is generally green  where as the inner side have red pigments that varies in shade depending on the age of the trap. Venus flytrap needs wet roots, poor acidic soil, high humidity and full sunlight to grow. The recommended soil  mixtures is one that contains sphagnum moss and sand. The plant produces the flowers in  a tall stalk above the leaves. Seeds produces by the flowers are very tiny. The Venus flytrap is listed as an endangered species. Venus flytrap is endemic to a restricted area of the Carolina’s coastal plain including southeastern, North Carolina and northeastern south Carolina.

Eskimo Curlew (Numenius Borealis)- Shorebird



Eskimo curlew is a small , mostly brown shore bird. It is a medium sized shorebird with a slender, slightly  down curved  bill. It is approximately 30 cm tall, has short bluish gray legs and a rich cinnamon color on its belly and wing linnings. It belongs to the family Scolopacidae. Eskimo curlews migrate from breeding grounds in the Arctic  tundra through  the north American prairies to wintering grounds on the pakpas grasslands of Argentina. Eskimo curlew’s habitat includes grasslands, plowed fields, pastures  and mudflats.  Eskimo Curlew is close to being extinct.

The Eskimo curlew eats both plants and animals. The Eskimo curlew’s diet consist of freshwater insects and  the fruit of Black Crowberry.  It also eats ants, worms and other invertebrates found on shores. In the coastal areas they feed on snails and along the Atlantic coast they eat beetles, spider, moth, seeds and other  berries. The Eskimo curlew is endangered because of unrestricted overhunting for the market, especially during its northward spring migrations. This bird also has a tame nature and is extremely friend, making it easy prey for hunters. Eskimo curlew’s nest are just a hole in the ground. They are lined with decaying leaves and a thin sprinkling o hay. The eggs  have a color similar to that of surroundings grass, being dark brownish green to blue blotched with brown.

Pothos – Devil’s Ivy





                Pothos  is one of the easiest houseplant to grow.  Its botanical name is Epipremnum aureum or Scindapsus aureus. But it is often referred as devil’s ivy or variegated philodendron. These plants can do well in indirect lights. One of the special features of this plant is that it can be grown both in water or in dry soil. Pothos are incredibly easy to root from cuttings. A part of of mother plant can be cut  and rooted in water . pothos also be grown in soil . they will thrive well in nutrient rich soil but do almost  in nutrient poor soil as well.

The natural form of Pothos is a trailing vine. Fluorescent light is acceptable as a light source. Its leaves are pointed heart shaped and can be green or variegated in white, yellow or a paler green. The leaf sizes vary with varieties and growing condition as well. The one that I had is green with white combination. I consider them as a best decorative plant as I can decorate the windows with them. The climbing/trailing habit makes them extremely decorative .Pothos plants prefer to dry out between watering.


 Pothos are poisonous too. The plant can cause irritation and vomiting if ingested due to the fact that it contains calcium oxalates. It is considered toxic to cats, dogs and children. It makes them very sick.

Portulaca Grandiflora – Sun lovers







                Portulaca  Grandiflora is one of my favorite  plant which doesn’t need any special care and brings the beauty to our garden with its different colors of flowers. It belongs to the family Portulacaceae. It is commonly known as portulaca, moss rose, rose moss and sun plant. Portuclaca flowers  tolerate many kinds of soils  but prefer sandy well drained soils and love the full bright sunlight. These plants will spread themselves very well. You do not need to water often for proper portulaca care. The cylindrical foliage of  portulaca flower retains moisture very well.


The flowers are borne on the stem tips. They open only during bright sunlight and closes at night and on cloudy days. There are many varieties with different colors of flowers such as orange, rose pink, red, yellow, white. The one which attracts me is white and  rose pink with its natural beauty. Moss rose makes a beautiful ground cover in a dry  or rocky area. In warm climates moss rose may self seed. Its reddish brown like stems and bright green leaves are thick , soft and juicy.


 Easily propagated by pinching off the stems of this plant into 2-4 inches length and stick them directly into moist sand or loamy soil and locate it in a sunny area. Portulaca can also be propagated from seeds that are as tiny as dust. Portulaca are originally from the hot, dry plains of Southern Brazil, Northern  Argentina, Uruguay.

Rafflesia was first discovered by the  Europeans Sir  Stamford Raffles and Dr. Joseph Arnold in 1816, near the town of  Bencooden in Sumatra. Therefore the this was named as Rafflesia  Arnoldii. The first description of Rafflesia  Arnoldi was given by Robert brown. This largest  tupe of  flower is upto  to  1metre  in diameter and weights  upto  9 kg .It takes around nine to twelve months for the buds to develop into flowers. Rafflesia flower is red in color with five leathery and speckled petals. The centre of Rafflesia flower has a well like structure and inside that well is a central raised disc with many vertical spines. The  Rafflesia  flower lasts around  five to seven  days  and it turns black and rots. It is a rare species that found only in certain areas of south east asia where there is much perciptation, particularly prevalent  in Sumatra. Raflesia grows to be about a yard wide and it smells like rotting meat. The horrid odor helps this rare plat to survive. The foul smell of rotting meat attracts the beetles and flies to pollinate. The flies and beetles should vsit both the  male and female  plants  for successful  pollination. It is a penetrating smell more repulsive then any buffalo carcass in an advanced stage of decomposition. It is a parasitic on members of genus  Tetrastigma. Throughout  its life it parasitizes on the host usually tropical lianas. It is hardly difficult to locate this flower as the buds take many months to develop  and the flower lasts for only few days.
