Vicia cracca | |
Vicia cracca (tufted vetch, cow vetch, bird vetch, blue vetch, boreal vetch), is a species of flowering plant in the pea and bean family Fabaceae. It is native to Europe and Asia. It occurs on other continents as an introduced species, including North America, where it is a common weed. It often occurs in disturbed habitats, including old fields and roadside ditches.
Cow vetch is in the family Fabaceae and similar to a pea in growth habit with climbing stems growing to 150 cm long, perennial, [1] sending out noose-like branched tendrils from the tips of its leaves when it contacts another plant and securely fastens itself. This can cause "strangling" of smaller plants. An individual plant may reach a length (or height) of 2 m with a white taproot, which may extend up to 1 m. The leaves are 3–8 cm long, pinnate, with 8–12 pairs of leaflets, each leaflet 5–10 mm long.
The plant is fast-growing and flowers prolifically, sending out 10 to 40 flowered one-sided racemes cascading pea-flower shaped purple to violet flowers from the leaf axil during its late spring to late summer flowering period. The flowers are mostly visited by bumblebees; [2] when the flowers drop off and tiny bright green seed pods 10–20 mm long, start to form. [3] Cow vetch is very similar to hairy vetch ( Vicia villosa ), but is distinguished from the latter by its smooth stem.
The seed pods are 2 cm long and contain 6 to 8 seeds. [4] They resemble those of a very small pea. The tiny seeds within are ripe when the pods have turned black. Unripened seeds are swollen and have a green tint to them, but they unswell when they become ripe. The seed pods vary from light brown to dark brown with black spots.
Vicia cracca is native to Europe and Asia, and has been introduced to large areas of North America. [5]
Recorded as very frequent on waste ground as an introduced species occurring casually. [6] In hedges and waste places. [4]
Cow vetch is widely used as a forage crop for cattle, and is beneficial to other plants because, like other leguminous plants, it enriches the soil in which it grows by its nitrogen-fixing properties. Cow vetch is also much appreciated by bees and butterflies as a source of nectar. The plant may also be used to curb erosion.
Owners of pet birds such as budgerigars often use cow vetch as a nutritious food; the birds are especially fond of the seeds but may also eat the foliage.
Its utility as a cover crop and source of green manure has encouraged the introduction and naturalisation of cow vetch far beyond its native range. In North America the plant is naturalised from southern Canada to upstate South Carolina; it is considered an invasive weed in some areas and its sale may be regulated[ citation needed ].
Cow vetch can be a potentially detrimental species in areas where it is not native[ citation needed ]. The vetch may crowd out native plants, especially in areas of disturbed soil where the vetch may dominate before other plants have a chance to take hold. This is especially a concern in prairie and other natural habitat restoration or land reclamation projects in North America.
Vicia sativa, known as the common vetch, garden vetch, tare or simply vetch, is a nitrogen-fixing leguminous plant in the family Fabaceae. It is now naturalised throughout the world occurring on every continent, except Antarctica and the Arctic. The centre of diversity is thought to be the Fertile Crescent, although gold standard molecular confirmation is currently not available.
Lotus corniculatus is a flowering plant in the pea family Fabaceae, native to grasslands in temperate Eurasia and North Africa. Common names include common bird's-foot trefoil, eggs and bacon, birdsfoot deervetch, and just bird's-foot trefoil, though the latter name is often also applied to other members of the genus.
Vicia is a genus of over 240 species of flowering plants that are part of the legume family (Fabaceae), and which are commonly known as vetches. Member species are native to Europe, North America, South America, Asia and Africa. Some other genera of their subfamily Faboideae also have names containing "vetch", for example the vetchlings (Lathyrus) or the milk-vetches (Astragalus). The lentils are included in genus Vicia, and were formerly classified in genus Lens. The broad bean is sometimes separated in a monotypic genus Faba; although not often used today, it is of historical importance in plant taxonomy as the namesake of the order Fabales, the Fabaceae and the Faboideae. The tribe Vicieae in which the vetches are placed is named after the genus' current name. The true peas (Pisum) are among the closest living relatives of vetches.
Vicia villosa, known as the hairy vetch, fodder vetch or winter vetch, is a plant native to some of Europe and western Asia. It is a legume, grown as a forage crop, fodder crop, cover crop, and green manure. Although non-native, it occurs in all US states and is considered invasive by some states, such as Alaska, Florida, Georgia, Kansas, Michigan, Minnesota, Nebraska, Oregon, and Washington state — as well as in Japan and some parts of Europe where it is not native. It is also found in most Canadian provinces.
Cardamine hirsuta, commonly called hairy bittercress, is an annual or biennial species of plant in the family Brassicaceae, and is edible as a salad green. It is common in moist areas around the world.
Vicia hirsuta is a species of flowering plant in the pea and bean family Fabaceae.
Vicia tetrasperma the smooth tare, smooth vetch, lentil vetch or sparrow vetch, is a species of flowering plant in the bean family Fabaceae.
Vicia sepium or bush vetch is a species of flowering plant in the pea and bean family Fabaceae. A nitrogen-fixing, perennial, leguminous climbing plant that grows in hedgerows, grasslands, the edges of woodland, roadsides and rough ground. It occurs in western Europe, Crimea of Ukraine, Russia including Siberia, Caucasus and Central Asia. It can also be found in eastern Canada, north-eastern states of the USA and, where suitable habitat occurs, in Greenland. It is native to, and has been recorded in, almost all parts of Britain, Ireland and associated islands.
Vicia sylvatica, known as wood vetch, is a species of flowering plant in the bean family Fabaceae. It was described by Carl Linnaeus.
Vicia lathyroides is a plant species in the bean family Fabaceae. It is native to Europe and western Asia, and it is known on other continents as an introduced species. It is an annual herb with pealike blue- or purple-tinged flowers about half a centimeter wide and hairless legume pods up to 3 centimeters long.
Lathyrus nissolia, the grass vetchling or grass pea, is a species of flowering plant in the pea and bean family Fabaceae. It is native to most of Europe, Maghreb, Levant and the Caucasus. Despite its common names, it is not a grass, but belongs to the legume family Fabaceae.
Lathyrus linifolius is a species of pea, commonly called bitter vetch or heath pea. The name bitter vetch is also sometimes used for Vicia ervilia and also for Vicia orobus. The tubers of Lathyrus linifolius were formerly used as an appetite suppressant in medieval Scotland, and this use has brought the plant to recent medical attention. Attempts are being made to cultivate the plant on a commercial scale.
Vicia benghalensis is a species of vetch known by the common names purple vetch and reddish tufted vetch. It is native to southern Europe, North Africa, and nearby islands, and it is utilized elsewhere in agriculture and may be present in the wild as an introduced species. It is an annual herb with a climbing stem which is coated in hairs, often densely, making the plant appear silvery white. Each leaf is made up of several pairs of elongated leaflets which measure up to 3 centimeters in length. The inflorescence is a one-side raceme of several dark reddish purple flowers. Each flower has a densely hairy calyx of sepals and a tubular corolla between one and two centimeters in length. The fruit is a flat, hairy legume pod up to 3.5 centimeters long containing multiple seeds.
Aeschynomene virginica is a rare species of flowering plant in the legume family known by the common names Virginia jointvetch and sensitive jointvetch. It is native to a small section of the East Coast of the United States, where it has a fluctuating annual global population scattered in about 20 mostly small occurrences. Counts and estimates revealed two populations in New Jersey including several thousand individuals, one population of a few hundred plants in Maryland, several variable and unstable populations in ditches in North Carolina, and several populations including about 5000 individuals in Virginia. Habitat alteration has reduced the number of sites where the plant can grow. The plant became a federally listed threatened species of the United States in 1992.
Vicia menziesii is a rare species of flowering plant in the legume family known by the common name Hawaiian vetch. It is endemic to Hawaii, where it is known only from the island of Hawaii. It is threatened by habitat loss and exotic plants. It has been federally listed as an endangered species of the United States since 1978. It was the first Hawaiian plant to be placed on the Endangered Species List.
Vicia orobus is a species of leguminous plant in the genus Vicia, known as wood bitter-vetch. It is found in Atlantic areas of Europe, especially in the rocky edges of seasonally-grazed fields. It grows up to 60 cm (24 in) tall, and has no tendrils at the ends of its pinnate leaves. Its flowers are white with purple veins, and are borne in groups of 6 or more.
Astragalus crassicarpus, known as ground plum or buffalo plum, is a perennial species of flowering plant in the legume family, Fabaceae, native to North America. It was described in 1813. The fruit is edible and was used by Native Americans as food and horse medicine. It is a host of afranius duskywing larvae. It is also known as groundplum milkvetch and pomme de prairie.
Vicia grandiflora, commonly known as large yellow vetch and bigflower vetch, as well as large-flowered vetch, is a common herbaceous plant species in the family Fabaceae, which occurs as a native plant species in Europe and Asia, as well as an introduced vetch species in North America.
Vicia tenuifolia, the fine-leaved vetch,cow vetch, fodder vetch or bramble vetch, is a herbaceous perennial plant species in the family Fabaceae. This species is widespread in Europe and some parts of both Asia and Africa. In some other areas it occurs as an introduced species. In a few countries this edible vetch is used as food for both humans and farm animals.
Vicia bithynica known as Bithynian vetch, is a species of flowering plant in the bean family Fabaceae. It was described by Carl Linnaeus, initially as Lathyrus bithynicus but later moved to the genus Vicia (vetches). The specific name is derived from Bithynia, an ancient kingdom situated on the north coast of Anatolia, in modern day Turkey.
