[49] Such oxidative modification could rupture animal cell membranes. In the wild they get over this slow period very quickly. [5], Dionaea muscipula occurs naturally only along the coastal plain of North and South Carolina in the U.S, with all known current sites within 90 km of Wilmington, North Carolina. It is a dwarf plant. [66] The State of North Carolina lists Dionaea muscipula as a species of "Special Concern–Vulnerable". Although widely cultivated for sale, the population of the Venus flytrap has been rapidly declining in its native range. [76] Because the mature plants and new seedlings are typically destroyed in the regular fires that are necessary to maintain their habitat, D. muscipula's survival relies upon adequate seed production and dispersal from outside the burnt patches back into the burnt habitat, requiring a critical mass of populations, and exposing the success of any one population to metapopulation dynamics. Except for 'filiformis', all of these can be stages in leaf production of any plant depending on season (decumbent in summer versus short versus semi-erect in spring), length of photoperiod (long petioles in spring versus short in summer), and intensity of light (wide petioles in low light intensity versus narrow in brighter light).

The Venus flytrap's brilliant plan: By using their specially-modified snap-trap leaves, they can get nitrogen by catching and digesting a wide variety of insects—and maybe even some small … [26] The edges of the lobes are fringed by stiff hair-like protrusions or cilia, which mesh together and prevent large prey from escaping. With the Venus flytrap, prey is limited to beetles, spiders and other crawling arthropods. It grows in Latitude 34 but not in 35. Researchers have proposed a series of steps that would ultimately result in the complex snap-trap mechanism:[54][55], Phylogenetic studies using molecular characters place the emergence of carnivory in the ancestors of Dionaea muscipula to 85.6 million years ago, and the development of the snap-trap tn the ancestors of Dionaea and its sister genus Aldrovanda to approximately 48 million years ago. [39] Carnivory has evolved independently six times in the angiosperms based on extant species, with likely many more carnivorous plant lineages now extinct. It forms a basal rosette of distinct leaves that are attached to a short rhizome. [15][16], On 2 April 1759, the North Carolina colonial governor, Arthur Dobbs, penned the first written description of the plant in a letter to English botanist Peter Collinson. Venus flytraps usually flower in the spring. In the open, untripped state, the lobes are convex (bent outwards), but in the closed state, the lobes are concave (forming a cavity). [7][8] The Latin word muscipula ("mousetrap") is derived from mus ("mouse") and decipula ("trap"), while the homonym word muscipula ("flytrap") is derived from musca ("fly") and decipula ("trap"). When an insect or spider crawling along the leaves contacts a hair, the trap prepares to close, snapping shut only if another contact occurs within approximately twenty seconds of the first strike. The trapping mechanism is tripped when prey contacts one of the three hair-like trichomes that are found on the upper surface of each of the lobes. [35] A 1958 survey of herbaria specimens and old documents found 259 sites where the historical record documented the presence of D. muscipula, within 21 counties in North and South Carolina. The genus name, Dionaea ("daughter of Dione"), refers to the Greek goddess Aphrodite, while the species name, muscipula, is Latin for both "mousetrap" and "flytrap". [55][56], A 2009 study[54] presented evidence for the evolution of snap traps of Dionaea and Aldrovanda from a flypaper trap like Drosera regia, based on molecular data. Zones: 6-9 (5-10).

Oxidative protein modification is likely to be a pre-digestive mechanism used by Dionaea muscipula. trappers1 … [36] As of 2019, it was considered extirpated in North Carolina in the inland counties of Moore, Robeson, and Lenoir, as well as the South Carolina coastal counties of Charleston and Georgetown. [51], Carnivory in plants is a very specialized form of foliar feeding, and is an adaptation found in several plants that grow in nutrient-poor soil. [7][11] The term is similar to the term tippet-de-witchet which derives from tippet and witchet (archaic term for vagina). The use of similar biological pathways in the traps as non-carnivorous plants use for other purposes indicates that somewhere in its evolutionary history, the Venus flytrap repurposed these genes to facilitate carnivory. [62], Venus flytraps are by far the most commonly recognized and cultivated carnivorous plant, and they are frequently sold as houseplants. The mechanism by which the trap snaps shut involves a complex interaction between elasticity, turgor and growth. However, they can bloom in any season when the conditions are not similar to their natural habitat. According to the American Cancer Society, these products are promoted in alternative medicine as a treatment for a variety of human ailments including HIV, Crohn's disease and skin cancer, but "available scientific evidence does not support the health claims made for Venus flytrap extract". More commonly, they are propagated by clonal division in spring or summer. Alternatively, cells in the inner layers of the lobes and midrib may rapidly secrete other ions, allowing water to follow by osmosis, and the cells to collapse.

Your Venus Flytrap likes to sip from a straw to get its water, not be doused and dunked in at all times. [3] It catches its prey—chiefly insects and arachnids—with a trapping structure formed by the terminal portion of each of the plant's leaves, which is triggered by tiny hairs (called "trigger hairs" or "sensitive hairs") on their inner surfaces. For most of the 20th century, this relationship was thought to be coincidental, more precisely an example of convergent evolution. For example, when grown indoors without dormancy, some Venus flytrap flower during the winter. The description was before John Ellis' letter to The London Magazine on 1 September 1768,[8] and his letter to Carl Linnaeus on 23 September 1768,[22] in which he described the plant and proposed its English name Venus's Flytrap and scientific name Dionaea muscipula.[23]. Dionaea muscipula - Venus Flytrap. It should be kept indoors or in a warm place for optimum growth. [31] One such place is North Carolina's Green Swamp. Flytraps that have more than seven leaves are colonies formed by rosettes that have divided beneath the ground. The trap only shuts when there have been two stimulations of the trigger hairs; this is to avoid inadvertent triggering of the mechanism by dust and other wind-borne debris. "[14][18] A year later, Dobbs went into greater detail about the plant in a letter to Collinson dated Brunswick, 24 January 1760.[19][20][21]. Venus flytraps can also be propagated in vitro using plant tissue culture. The cultivars 'Akai Ryu and 'South West Giant' have gained the Royal Horticultural Society's Award of Garden Merit. All plant cells can be made to react by touch or injury. The Venus flytrap plant cannot survive harsh freezing conditions. They don't eat them", "Quantification of insect nitrogen utilization by the Venus flytrap Dionaea muscipula catching prey with highly variable isotope signatures", "How does the Venus flytrap digest flies? The seeds germinate immediately without a dormant period. Available in Stores. [53], The "snap trap" mechanism characteristic of Dionaea is shared with only one other carnivorous plant genus, Aldrovanda. You want your Venus Flytrap to have access to water at all times, but not be completely immersed in water for too long, because this is not natural for the plant, and will lead to rot. [70], The Venus flytrap is only found in the wild in a very particular set of conditions, requiring flat land with moist, acidic, nutrient-poor soils that receive full sun and burn frequently in forest fires, and is therefore sensitive to many types of disturbance. [5] A 1958 study found 259 confirmed extant or historic sites. [5], Fire suppression is another threat to the Venus flytrap. [34], They are full sun plants, usually found only in areas with less than 10% canopy cover. Venus Flytrap Set 1 Sundew Set 1 Mix Mini-egg Terrarium Set with Carnivorous Plant Seeds Carnivorous Plant Seeds Bog Orchid Seeds Bog Plant Seeds Special Orders Ship Plant Potted … The carnivorous Venus flytrap, on the other hand, even notices when a lightweight like a fly lands on it. When their flowers are pollinated, they create seeds. The speed with which traps close can be used as an indicator of a plant's general health. It bears a white flower. Although it has been successfully transplanted and grown in many locales around the world, it is native only to the coastal bogs of North and South Carolina in the United States, specifically within a 100-kilometer (60 mi) radius of Wilmington, North Carolina. The flower is pollinated from various flying insects such as sweat bees, longhorn beetles and checkered beetles. If the prey is too small and escapes, the trap will usually reopen within 12 hours. Drosera consume smaller, aerial insects, whereas Dionaea consume larger terrestrial bugs. Dionaea are able to extract more nutrients from these larger bugs. Thus, natural fires are an important part of its habitat, required every 3–5 years in most places for D. muscipula to thrive. Venus fly trap, Venus flytrap: Plant Type: Herbaceous plant with a perennial life cycle: Mature Size: 6 to 12 inches tall by 6 to 9 inches wide: Sun Exposure: Full sun to partial shade: Soil Type: Poor, sandy soil kept constantly wet: Soil pH: Acidic: Bloom Time: May to June: Flower … When the trigger hairs are stimulated, an action potential (mostly involving calcium ions—see calcium in biology) is generated, which propagates across the lobes and stimulates cells in the lobes and in the midrib between them.
