Sporobolus heterolepsis ‘Gone with the Wind’ – Dwarf Prairie Dropseed

From Walters Gardens:

This is a new seed strain of the native grass known for its hair-like foliage and mass planting appeal. ‘Gone with the Wind’ is shorter than the species, but still maintains many of the characteristics that made this type of grass popular. Its short, green foliage is topped by wispy, airy and aromatic tan flower panicles. The plant, as the name suggests, gently sways with the wind, creating unique movement in the garden. Foliage takes on red overtones in late fall.
