I planted some lespedeza as a companion crop to some cool season grass in a pasture a few years back and deer were in there regularly in later summer. Like Wooddust stated, it will come on strong a little later in the growing season and may be more palatable when clover has slow down its growth due to summer weather. On a sidenote, clover will out produce lespedeza in total tons/acre. There are several improve varieties out there now as well.
