September is the time of year when ornamental grasses truly makes an impact in the landscape. Many have showy plumes of airy seedheads that move gracefully in the breeze and offer winter interest even after they age to their seasonal hues of tan and brown.

We carry many types of ornamental grasses. All are winter hardy and clump forming (i.e. they do not run around!). Following is a brief overview of several of our most popular hardy perennial grasses for sun to light shade (we’ll feature shade grasses in a later article).

Switch Grass: Panicum

Prairie parentage gives excellent hardiness & vigor to this group. Seeds are a food source for birds in winter.

  • ‘Shenandoah’: (left image) Foliage grows to 36″, with the top half of the blades becoming dark red by mid-summer. Foliage is topped in late summer by airy red seedheads. Total height 4′-5′.
  • ‘Northwind’: (right image) Dense columnar form. Olive green foliage. Airy green seedheads aging to tan. Excellent winter presence. Height 4′-5′.

Prairie Dropseed: Sporobolus

A prairie native, perfectly adapted to our Wisconsin growing conditions. Delicate soft green blades and “see through” whispy seedheads in summer. Height to 36″.

Silver Grass: Miscanthus

Sometimes called ‘Northern Pampas Grass’ due to it feathery cloud-like plumes which remain attractive throughout the winter months. We have several varieties, ranging in height and in foliage color and form. Height ranges from 4′-7′, depending on variety.

Little Bluestem: Schizachyrium

We carry the native prairie species as well as selected cultivars. Vertical form and blue toned foliage that becomes purple & deep red as fall temperatures drop.

Feather Reed Grass: Calamogrostis

Deservedly extremely popular as a landscape plant. Narrow, upright habit. Wheat colored plumes form in June and remain throughout the growing season and into winter. Foliage is either green or variegated, depending upon cultivar.

Big Bluestem: Andropogon

Another prairie native that is sometimes referred to as “Turkey Foot” because of the characteristic shape of its seedhead, which resembles a turkey’s foot! This tall drought tolerant grass was once the dominant plant in many of our midwestern tallgrass prairies.
