This grass has fluffy pinkish tufts on stalks that form airy clouds above a symmetrical clumping mound. I'm no ornamental grass expert, but this to me looks unmistakably like Muhly grass [Muhlenbergia capillaris].
|Muhly grass (Muhlenbergia capillaris) not as pink as some photos online, but then again it was in January|
|Pink Muhly Grass - up close you can see the individual airy plumes of the Muhlenbergia capillaris|
|This clump looks a little tan rather than pink, but from side view the airy cloud effect is very clear! So fluffy!!!|
