Full Sun, Part Shade
Medium Water

Mature Size: 30”X 2’
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.

Low Water

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.

Full Sun, Part Shade
Medium Water

Mature Size: 4’X 3’
Blooming Season: Summer
Flower Color: Hazy pink-purple

There are many named cultivars of Switchgrass, all variations on the theme of tall upright leaf blades crowned in late summer with a haze of lacy seed heads. The leaves may be green or blue green in summer, changing to a range of pinks and reds as temperatures cool and the days get shorter at the end of the growing season. Switchgrass can be grouped between evergreens or stand alone as an accent. Songbirds will love you for adding it to your garden.
