Prey -Trapping Plant "A Carnivore"

2007.08.08






I saw my first Pitcher Plant 11 years ago on one of my first canoe paddles and was besotted by them there behavior and survival in nature.I had an old camera then taking photos not presenting the plant well. This time with my digital camera I was able to capture the Plant in its entire magnificence. I hope you enjoy reading the story of this amazing plant almost humane.

Pitcher plant Genus: Sarracenia purpurea(from the Latin meaning purple)
Leaves evergreen, modified into pitchers and arranged in a rosette. Pitchers curved and decumbent, to 17" and widening prominently toward the mouth. Hood on the pitcher positioned vertically; the pitcher usually being full or partly full of rainwater. Leaf color from bright yellow-green to dark purple and most commonly a middle variation with strong red venation. The leaves, or pitchers, are produced each year from stems arising from the rhizomes and remain evergreen unless unduly exposed. Flower petals, sepals, and bracts rose pink to dark red. Flowers solitary, on a leafless stem, 1'-2', arising from the rhizome

Pitcher plants are carnivorous plants whose prey-trapping mechanism features a deep cavity filled with liquid known as a pitfall trap. It has been widely assumed that the various sorts of pitfall trap evolved from rolled leaves, with selection pressure favouring more deeply cupped leaves over evolutionary time. Foraging, flying or crawling insects such as flies are attracted to the cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments, and nectar bribes. The sides of the pitcher are slippery and may be grooved in such a way so as to ensure that the insects cannot climb out. The small bodies of liquid contained within the pitcher traps are called phytotelmata. They drown, and the body of the insect is gradually dissolved. This may occur by bacterial action (the bacteria being washed into the pitcher by rainfall) or by enzymes secreted by the plant itself. Furthermore, some pitcher plants contain mutualistic insect larvae, which feed on trapped prey, and whose excreta the plant absorbs. Whatever the mechanism of digestion, the prey items are converted into a solution of amino acids, peptides, phosphates, ammonium and urea, from which the plant obtains its mineral nutrition (particularly nitrogen and phosphorus). Like all carnivorous plants, they occur in locations where the soil is too poor in minerals and/or too acidic for most plants to be able to grow.
Bogs, savannas, and flat woods. The very wettest parts of bogs are favored, often restricting the species to the edges of bogs. Forms dense, floating mats on the water at the edges of bog ponds and lakes and across acid streams.

maharba When I lived in Louisiana I had one of those plants. It tried to eat one of those giant cockroaches and croaked in the process. My fault since I'm the one that fed it.
