Common name: Little bluestem, beard grass
Schizachyrium scoparium: The bluish blades of this grass can reach 1.5 metres (4-5 feet) in height by the end of the summer. We have several cultivars, including S. scoparium 'Itasca' and S. scoparium 'The Blues'. It is very drought-tolerant and does well in poor soil. It is native to the US Midwest north to Canada.
