IPSM Volume 12 Issue 2 (image) Cambridge University Press Share Print E-Mail Caption Shown is the invasive weedy plant Lonicera japonica Thunb., commonly known as Japanese honeysuckle. This plant, a member of the Caprifoliaceae family, is native to east Asia and introduced into many countries around the world, including the US. It is a perennial vine that produces fragrant flowers and overtops other plants, reducing light available for native species. Increases in atmospheric CO2 may favor introduced weeds such as L. japonica. This picture was taken at the edge of a patch of woodland in a park in Newark, Delaware. Credit Steven J.
