Dark Alley is a blend of grain sorghum, forage sorghum, spring barley and vetch. The vetch provides nitrogen to the soil to aid in the nitrogen hungry Sorghum growth. It can be planted as a late season food source, or can also be used to section or screen off larger plots. Works great in larger plots to steer deer movement into range of your stand or blind. Grows up to 6' tall. Plants 1/2 acre.
