Giant Sacaton, Sporobolus wrightii

Exposure: Full Sun

Water: Medium

Height and Spread: 5’ x 5’

Blooming Season: August to October

Region: All Areas

This deciduous warm season bunchgrass is a delight in fall gardens. In the late summer, seed stalks appear, providing beautiful visual interest when backlit by the sun and gently blowing in the wind. This grass occurs naturally in floodplains and does well if deeply watered twice a month in summer. Water monthly the rest of the year. Giant Sacaton looks lovely when mass planted but can also stand alone when planted among late blooming summer perennials. In late February, trim this grass to about a foot from the ground so it will be ready for spring.

Exposure: Sun, Partial Shade

Water: Low Water

Height and Spread: 30” x 24”

Blooming Season: Late Summer - Fall

Region: All Areas

This long, wispy, coarse, medium blue-green grass looks lovely in late summer when it sends out tall seed heads. These are little seeds that dangle side-by-side on a stiff stalk. This plant is perfect to mix in and among a meadow area, for use on slopes to control erosion or as accents in a perennial bed. It is very heat tolerant, needing only a soaking twice a month in the heat of the summer. This grass should be mowed 6 inches high or higher once a year in the late winter.

Blooming Season: Spring
Seed Head Color: Pale tan

Surprisingly heat and drought tolerant for a cool season grass, the dark green color of ‘Karl Foerster’ leaves topped with its pale straw colored seed heads is a large part of the appeal of this cool season bunchgrass. Its vertical form adds exclamation points in the midst of cool, low slung flowers such as Catmint and Winecups, or amplifies the upright lines of Penstemons and Salvias.

Mature Size: 2’X 2’
Blooming Season: Fall
Color: Pink to red

Little bluestem is a key component of much of the prairie grassland throughout the West, where it goes unnoticed until late in the year when its strong color contrast of scarlet or pink leaves among the blond seed heads of other native grasses gives it the impact of a wash of wildflowers long after the growing season has ended. Easily grown from seed or plants, the slender upright clumps sway in the breeze.
