The plant thus named by V.N. Voroshilov is Vicia japonica as described by Asa Gray. Vicia sativa, known as the common vetch, garden vetch, tare or simply the vetch , is a nitrogen fixing leguminous plant in the family Fabaceae.  Crown Vetch. Crown Vetch (Securigera Varia) is a plant that is native to parts of Africa, Asia, and Europe, and has been brought to North America. It's often planted along road ways, and used for erosion control, as well as in soil rehabilitation due to it's ability to add nitrogen into the soil. Crown Vetch Flower. Crown Vetch is a toxic plant. It's safe to touch, and has a pleasant smell, but the plant and seeds are poisonous if eaten. Crown Vetch can cause vomiting and diarrhea, as well as cause the pulse to drop, and may even cause death if enough is ingested. The bitter vetch, too, is grown extensively for this purpose, as are hairy vetch (V. villosa, also called fodder vetch), bard vetch (V. articulata), French vetch (V. serratifolia) and Narbon bean (V. narbonensis). V. benghalensis and Hungarian vetch (V. pannonica) are cultivated for forage and green manure. Broad beans remained prominent though, be it in the Near East where the seeds are mentioned in Hittite and Ancient Egyptian sources dating from more than 3,000 years ago as well as in the Hebrew Bible, or in the large Celtic Oppidum of Manching from La Tene Tène europe 2,200 2200 years. ago Thanked 1,194 Times in 655 Posts. If you know for sure it's vetch it's a relative of peas, alfalfa-it's a legume. It's used for animal feed but I've never eaten it or alfalfa. Some people use it as a cover crop and chop it down before it goes to seed and plant right through the stubble. Like any legume, it adds nitrogen to soil. We have it wild in a couple of spots on our property but I just chop it with a weed eater.  Canavanine, a toxic analogue of the amino acid arginine, has been identified in Hairy Vetch as an appetite suppressant for monogastric animals, while Narbon bean contains the quicker-acting but weaker γ-glutamyl-S- ethenylcysteine. In common vetch, γ-glutamyl-β- cyanoalanine has been found. Broad beans remained prominent though, be it in the Near East where the seeds are mentioned in Hittite and Ancient Egyptian sources dating from more than 3,000 years ago as well as in the Hebrew Bible, or in the large Celtic Oppidum of Manching from La Tene Tène europe 2,200 2200 years. ago 1 Poisonous – while not containing any specific toxins, Vetch contains certain chemicals which have the ability to block the absorption of essential nutrients. 2  If too much of this plant is eaten for too long, then people and animals can develop deficiencies which can cause minor to significant health problems.  Beginner foragers sometimes mistake Crown Vetch for Red Clover. Since Clover is edible (and is actually quite tasty), this can be a very bad mix up. Always check and double check when out foraging, and pay attention to the details of the plant. Crown Vetch Flower. Crown Vetch is a toxic plant. It's safe to touch, and has a pleasant smell, but the plant and seeds are poisonous if eaten. Crown Vetch can cause vomiting and diarrhea, as well as cause the pulse to drop, and may even cause death if enough is ingested. Bitter vetch (V. ervilia) was one of the first domesticated crops. It was grown in the Near East about 9,500 years ago, starting perhaps even one or two millennia earlier during the Pre-Pottery Neolithic A. Broad beans remained prominent though, be it in the Near East where the seeds are mentioned in Hittite and Ancient Egyptian sources dating from more than 3,000 years ago as well as in the Hebrew Bible, or in the large Celtic Oppidum of Manching from La Tene Tène europe 2,200 2200 years. ago Physical Characteristics. Vicia americana is a PERENNIAL growing to 1 m (3ft 3in) by 1 m (3ft 3in). It is in flower in July. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile. It can fix Nitrogen.  Growing a fall cover crop is one of those good garden tasks that we all know we should do, but often don't find the time for. Cover crops control erosion, attract pollinating insects, break up heavy soils, improve soil fertility and structure, and reduce weeds. Plus, some, such as red clover, have edible flowers. Legume cover crops, such as hairy vetch and crimson clover, through a symbiotic relationship with the rhizobia bacteria on their roots, convert atmospheric nitrogen into a form plants can use to grow. When the cover crop is tilled under, the nitrogen is released for the next crop.
