Korean is an annual lespedeza introduced into the United States in 1919. It is adapted to a more northern area than striate varieties. It is mainly grown from Eastern Oklahoma and Kansas eastward to the Atlantic Seaboard. Leaves are broader and somewhat larger than striate leaves, and seed is borne somewhat differently. Otherwise, the two annual lespedezas are quite similar. Korean lespedeza is excellent both for hay and pasture, especially on soils that are acid or of low fertility. It reseeds readily to give semipermanent pasture.
