Reintroduced by SESE in 1997.] 'Black Amber Cane' was one of the earliest sweet canes introduced to American agriculture. It was supplanted by 'Redtop' which has a higher yield. Used primarily as a syrup sorghum. As a silage crop it has the hay and wild game quality of 'Merit'. Makes a good intercrop with beans and peas. Stalks range from 6 to 8' bearing large shiny black seeds. Pkt.
