Lespedeza cuneata (a.k.a. Chinese bushclover, Chinese lespedeza or sericea lespedeza) has been in New Jersey for some time, but seems to be more and more frequently growing in dense monocultures.

In the Pine Barrens, which has very little invasive species problems, Chinese bushclover is a problem on roadsides and other areas that receive heavy human disturbance. Roadside plant communities in the Pine Barrens are a significant refuge for early successional plants and are highly threatened by Chinese bushclover. (Note: Chinese bushclover is currently recommended for roadside seed mixes following construction…).

In areas outside of the Pines, Chinese bushclover can form dense monocultures in old fields. It seems possible that new infestations begin along field edges where farm equipment or vehicles create bare, compacted ground.

Chinese bushclover agressively spreads asexually via runners, which allows for domination of sites. It also makes this species difficult to control. Generally, foliar spraying with triclopyr is recommended. Burning in spring is NOT RECOMMENDED because it stimulates growth and flowering. As with any invasive species, early detection and rapid response is required to prevent further spread. If you are considering prescribed fire to manage a meadow, then be sure to search for and eradicate Chinese bushclover before burning.
