The plant known as 'bush vetch' is widely distributed, native to temperate regions across Eurasia. It thrives naturally in a variety of habitats from Western Europe to Central and Eastern Asia. 'bush vetch' has also been introduced to other areas, including parts of North America and East Asia, where it has established itself beyond its original range.

Bush vetch is highly toxic to humans through ingestion, particularly the seeds containing cyanide, potentially causing headache, dizziness, and cardiac arrest. Bush vetch also mildly poisons cats and dogs, leading to gastrointestinal upset or respiratory issues upon ingestion. Immediate veterinary care is crucial for pets. Extreme caution is advised to prevent accidental ingestion of any part of bush vetch.

Bush vetch, or Bush vetch, originates from Eurasia, which includes regions spanning from Europe to Asia. Classed as a weed largely due to its aggressive growth habits, it's highly adaptable and can thrive in a wide range of soils. The harmfulness lies in its ability to crowd out and overshadow other flowering plants and crops by being faster-growing and more vigorous. It reproduces via a profuse amount of seeds dropped from its flower pods, with each plant capable of producing thousands of seeds. The seeds are further spread by animals or through human activities such as soil movement. It can become a persistent issue for gardeners as seeds can remain viable in the soil for many years. The plant also propagates via its vigorous rhizome system, spreading vegetatively and making control efforts more complicated. All these factors combine to make bush vetch a potentially major concern in both gardens and agricultural settings.

The best season to remove bush vetch is in early spring, before it has a chance to flower and set seed.
