The Asiatic dayflower is considered an invasive weed in many areas where it has been introduced. In the United States, the Virginia Department of Conservation and Recreation, for example, categorises the species as "occasionally invasive" in its "Invasive Plant Species of Virginia". This means that the plant will "not affect ecosystem processes, but may alter plant community composition by outcompeting one or more native plant species". The species is typically limited to disturbed sites, whence it spreads relatively slowly. Within its native range in China it is also sometimes considered a pest, especially in the northeast of the country where it has caused economically significant agricultural damage in orchards.
