Sorghum halepense

Johnson grass

Perennial with vigorous spreading rootstocks that soon takes full possession of the land and is difficult to eradicate. In general appearance it is similar to sudan grass (Sorghum sudanense) but has persistent underground rootstocks that produce shoots from their nodes. Two or three crops of hay are frequently harvested in a season. Valuable pasture, but young plants may contain appreciable amounts of HCN and must therefore be grazed with care.
