(1-12") long. Flowers are on a long stalk to avoid trapping pollinators. This loss has continued, with over half the 10-km squares which remained in C. & S. England after 1930 now lost, including many in Norfolk. Some annuals. Pinguicula Gigantea + 12 seeds Plant Carnivorous rares carnivorous. The genus name Pinguicula is derived from the Latin word “pinguis,” meaning fat referring to the thick, greasy appearance of the leaves. Blooming Size Carnivorous Plant Pinguicula Pirouette. Butterworts are usually only able to trap small insects and those with large wing surfaces. These cells produce a mucilaginous secretion which forms visible droplets across the leaf surface. ... Pinguicula vulgaris. Wetland destruction has threatened several US species. In 1583, Clusius already distinguished between two forms in his Historia stirpium rariorum per Pannoniam, Austriam: a blue-flowered form (P. vulgaris) and a white-flowered form (Pinguicula alpina). ex Benj. The number of known species rose sharply with the exploration of the new continents in the 19th century; by 1844, 32 species were known. The pretty blue flowers are no clue for the more gruesome insect-eating habit of this plant. Common Names: Butterwort. - Substratum: wet soil. According to Linnaeus, this property has long been known by northern Europeans, who applied butterwort leaves to the sores of cattle to promote healing. The leaves have also been used in the north to steep in milk and to curdle or thicken it it. As the insect struggles, the edges of the leaves roll in to cover and digest the insect. Pinguicula macroceras ssp. Temperate Pinguicula produce carnivorous growth and flowers during the warmer weather of spring in North America and Europe. You can change your mind by clicking a link we put in the emails. The environmental threats faced by various Pinguicula species depend on their location and on how widespread their distribution is. Many butterworts cycle between rosettes composed of carnivorous and non-carnivorous leaves as the seasons change, so these two ecological groupings can be further divided according to their ability to produce different leaves during their growing season. Pinguicula can be found in north, central and south America, in Greenland, in most parts of Europe, at the very north-western tip of Africa and in some scattered areas in Asia. [14], Pinguicula belong to the Bladderwort family (Lentibulariaceae), along with Utricularia and Genlisea. [8] Other species, such as P. vulgaris, grow in fens. Pinguicula distribution, growth habit. [3] Temperate species flower when they form their summer rosettes while tropical species flower at each rosette change. [13] Additionally, butterwort leaves were used to curdle milk and form a buttermilk-like fermented milk product called filmjölk (Sweden) and tjukkmjølk (Norway). Many of the Mexican species commonly grow on mossy banks, rock, and roadsides in oak-pine forests. The temperate species and many of the Mexican butterworts are relatively easy to grow and have therefore gained relative popularity. The life of this carnivorous plant is dependent on the nutrients they get from captured insects. By Dr. Laurent Legendre. These plants are growing next to a window and are greener than plants grown in a greenhouse. In the few epiphytic species (such as P. lignicola), the roots form anchoring suction cups. They respond well to a mixture of two parts peat, one part silica sand, one part perlite and one part vermiculite. It occurs in Northern and Central Canada and in Northeast United States. The luring, retaining, and seizing of prey is the first steps in the feeding procedure for carnivorous plants; the end result of the process is absorption and digestion of nutrients sourced from these food supplies. The pretty blue flowers are no clue for the more gruesome insect-eating habit of this plant. Life Cycle: Half-hardy perennial. Blooming Size Carnivorous Plant Pinguicula Pirouette. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Australia is the only continent without any native butterworts. A common northern variety, Pinguicula vulgaris, inhabits bogs and light soils from New York and the New England states across the northern tier of Michigan to Montana, northern California, Washington, and … ex Lange Pinguicula longicornis Gay Pinguicula longicornis Gay ex Babington Pinguicula norica Beck Pinguicula occyptera Rchb. Cambridge University Press, Cambridge, UK. Pinguicula vulgaris L. – common butterwort Subordinate Taxa. A detailed study of the phylogenetics of butterworts by Cieslak et al. The only known annuals are P. sharpii, P. takakii, P. crenatiloba, and P. pumila. Pinguicula Growing and Care Guide. Pinguicula pumila Buswellii is similar except that it has yellow flowers. The name Pinguicula is derived from a term coined by Conrad Gesner, who in his 1561 work entitled Horti Germaniae commented on the glistening leaves: "propter pinguia et tenera folia…" (Latin pinguis, "fat"). Pinguicula pumila Buswellii is similar except that it has yellow flowers. Growing Region: Zones 5 to 10. In a letter to Asa Gray dated June 3, 1874, Charles Darwin mentioned his early observations of the butterwort's digestive process and insectivorous nature. Flower Details: Blue, violet, white or red. It was only in the late 19th century that the carnivory of this genus began to be studied in detail. When the job is done, the leaf opens again waiting on new victims. If placed in a growing chamber, the potted plants will grow very well. Bug Eating Butterwort! Pinguicula hirta Wormsk. Carnivorous plants (Drosera, Nepenthes, Dionaea, Sarracenia, Pinguicula, Utricularia, and others) belong to diverse plant families of unrelated taxonomic affinities. The catch their prey with sticky, glandular leaves. The biology of plants that eat animals (carnivorous plants) is fascinating. As the insect struggles, the edges of the leaves roll in to cover and digest the insect. 25 watching. The striking triangular leaves are sticky and trap a landing insect. The plant was discovered in 1987 by Alfred Lau … It catches small insects with its fairly thick, like fatty and sticky ground leaves (Latin word 'pinguiculus' means 'very fat'). They are found in areas in which  nitrogenous resources are known to be in low levels, infrequent or unavailable, due to acidic soil conditions. Butterwort (Common) Pinguicula vulgaris. "Boxes will be … Ecology and evolution of carnivorous plants. In order to catch and digest insects, the leaf of a butterwort uses two specialized glands which are scattered across the leaf surface (usually only on the upper surface, with the exception of P. gigantea and P. longifolia ssp. The round to egg-shaped seed capsules open when dry into two halves, exposing numerous small (0.5–1 mm), brown seeds. When the job is done, the leaf opens again waiting on new victims. P.villosa 2 - 4 (1, too, for Sibiria and Alaska) The secretory system can only function a single time, so that a particular area of the leaf surface can only be used to digest insects once.[3]. Unlike many other carnivorous plants that require sunny locations, many butterworts thrive in part-sun or even shady conditions. Sign up here to receive emails about plants and Plantlife’s work. During this time the roots (with the exception of P. alpina) and carnivorous leaves wither. Once the prey has become trapped in the peduncular glands, the sessile glands present will then produce enzymes needed to accomplish digestion and breaking down the digestible regions of the  prey for their nutrients; taking in the fluids of the food source by means of cuticular holes present on the leaf’s surface. The holes in the cuticle which allow for this digestive mechanism also pose a challenge for the plant, since they serve as breaks in the cuticle (waxy layer) that protects the plant from desiccation.
