The species is native to: prairies and open ground,
open woods, brackish marshes from eastern Canada to central and eastern
US and south to Central America.
Recommended spacing between plants: 40-80
cm (24-32") why such a difference?
When to divide: when it shows signs of
life in the spring, continuing until the new growth is about
12" tall; only in the spring (further
info on dividing grasses)
When to plant or transplant: plant bare root plants
only in late spring to early summer, when the soil
is warm, about the same time you plant your bean or corn
seeds. The roots will grow only in warm soil. Planting too
early in the spring may cause the roots to rot. Similar
story in the fall when the roots may not grow enough to
establish before the cold and wet of winter, resulting in
the demise of the plant.
When to cut back: before the new growth
starts to appear, but after the cold weather is over. Cut
back to about 3-4" from the crown of the plant.
Pronunciation: Panicum (PAN-ih-kum) virgatum (veer-GAH-tum)
