Panicum virgatum 'Heavy Metal' (Blue Switch Grass) - A deciduous warm-season narrowly upright clump-forming grass native to the American prairies. It has steely-blue upright foliage to 3-4 ft tall that turns a nice yellow color in fall and attractive airy pink-tinged flowers that rise a foot or more above the foliage in mid-summer. Plant in full sun. Tolerant of most soils and irrigation practices from dry to soggy - shorter when kept dry. Hardy into USDA zone 4. 'Heavy Metal' was a selection made by Kurt Bluemel with chalky-colored foliage - it is more upright than 'Prairie Sky'. It remains attractive as a dormant grass but should be cut back in late winter to early spring so not to detract from the newly emerging foliage. 

The information about Panicum virgatum 'Heavy Metal' that is displayed on this web page is based on research conducted in our nursery's horticultural library and from reliable online resources. We will also include observations made about this plant as it grows in our nursery gardens and other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We also incorporate comments that we receive from others and welcome hearing from anyone with additional information, particularly if they share cultural information that aids others growing this plant.

 
San Marcos Growers, established in 1979, will close at the end of 2025 so that the property can be developed for affordable housing.
