Spreading Hedge Parsley, Field Hedge Parsley, Common Hedge Parsley - Torilis arvensis


Family: Apiaceae - Carrot family Genus Common Name: Hedge Parsley Native Status: Introduced
Torilis arvensis - Spreading Hedge Parsley, Field Hedge Parsley, Common Hedge Parsley. Torilis arvensis, which has the USDA national common name of Spreading Hedge Parsley, is also known as Field Hedge Parsley and as Common Hedge Parsley. It is introduced in the United States, native only to British Columbia in North America. Even though it has spread widely in the United States due to the sticky bur seeds, it apparently does not crowd out native species too aggressively, because it is listed as an obnoxious weed in only one state - Washington, which is, of course, right across the border from BC, where it is native. Torilis japonica is a very similar species, and is in fact listed as a synonym of T. arvensis at the Department of Biological Sciences at Vanderbilt University. However, the USDA lists it as a separate species, as does Dr. John Hilty over at IllinoisWildflowers.info. According to Dr. Hilty, the primary difference between the plants is that T. japonica has about 8 linear bracts at the base of each compound umbel. This feature is missing in T. arvensis.
