where does giant hogweed grow in the us
Heracleum mantegazzianum Giant hogweed was among many foreign plants introduced to Britain in the 19th century as ornamental plants. It is now widespread throughout the British Isles, especially along riverbanks. By forming dense stands, they can displace native plants and reduce wildlife habitats.[9] It has spread in the northeastern and northwestern United States, and southern Canada and is an invasive species in Germany, France, and Belgium, overtaking the local native species, Heracleum sphondylium.[9] Giant hogweed was introduced to the Baltics during the Soviet era as fodder for cattle.[10]
Corn snake The corn snake (Pantherophis guttatus) is a North American species of rat snake that subdues its small prey by constriction.[4][5] It is found throughout the southeastern and central United States. Their docile nature, reluctance to bite, moderate adult size, attractive pattern, and comparatively simple care make them popular pet snakes. Though superficially resembling the venomous copperhead and often killed as a result of this mistaken identity, corn snakes are harmless and beneficial to humans.[6] Corn snakes lack functional venom and help control populations of wild rodent pests that damage crops and spread disease.[7]
