'''''Sorghum'' × ''drummondii''''' ('''Sudan grass'''), is a hybrid-derived species of grass raised for forage and grain, native to tropical and subtropical regions of Eastern Africa. It may also be known as ''Sorghum bicolor'' × ''Sorghum arundinaceum'' after its parents. Some authorities consider all three species to be subspecies under ''S.&nbsp;bicolor''.<ref name=ncbi/>

The plant is cultivated in Southern Europe, South America, Central America, North America and Southern Asia, for forage or as a cover crop.<ref name=tpl/> When treated as a weed, it is known as '''shattercane'''.<ref>{{cite journal |last1=Kanatas |first1=Panagiotis |last2=Gazoulis |first2=Ioannis |last3=Zannopoulos |first3=Stavros |last4=Tataridas |first4=Alexandros |last5=Tsekoura |first5=Anastasia |last6=Antonopoulos |first6=Nikolaos |last7=Travlos |first7=Ilias |title=Shattercane (Sorghum bicolor (L.)

Like sorghum, new plant growth, especially after a drought or frost, can be toxic to grazing animals.<ref>{{cite web |title=Sorghum x drummondii |url=https://plants.ces.ncsu.edu/plants/sorghum-x-drummondii/ |publisher=NC State Extension |access-date=15 June 2025}}</ref>
