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 displayed on this page about Panicum virgatum 'Heavy Metal' is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties as we liquidate remaining supplies and equipment.
