place of origin: Mexico and Central America

urban habitat: commonly found in disturbed cultivated landscapes, vacant lots, waste areas, roadsides, pavement openings, neglected parks.

history: Galinsoga ciliata arrived in the US in the early 1900’s and is now found throughout much of the US and southern Canada, as well as in Europe, North Africa, and Asia. It has a competitive edge over many plants due to its ability to complete its life cycle from germination to seed production in 3-4 weeks. It is said to be one of the most difficult to control weeds in agriculture. It is a common weed in Asia where it is eaten. Its scientific name Galinsoga is named for the 18th century Spanish physician and botanist Mariano Martinez Galinsoga.
