Miscanthus sacchariflorus ‘Robustus’ Posted byLance Kleckner October 11, 2013December 28, 2022 Leave a comment on Miscanthus sacchariflorus ‘Robustus’ Miscanthus sacchariflorus ‘Robustus’ is a fast growing grass. The grass has running rhizomes and can be used for fast growing erosion control. This Miscanthus can grow taller than me, too.
