Panicum
Switch Grass
Our Panicums are warm season prairie grasses native to North America. Resistant to heat, drought and extreme cold, Switch Grass hosts a cloud of inflorescences—a mystifying hologram of tiny red seeds that mature to black in late summer. If grown in drifts and not cut back until early spring, Panicums promise a lively winter show. After several frosty nights, they stiffen and adopt the warm glowing color and soft rustling sound of wheat.
Populating Delaware’s coastal sand dunes near the town of Dewey, noted grass expert, Rick Darke selected this kingly Panicum for its blue, oh-so-blue smooth glaucous blades and elegant fountainlike stance. Distinctive straight-up stems bolster light airy plumes, followed by caramel-colored seed heads persisting well into winter. ‘Dewey Blue’ is not only a stunning showman but an enduring workhorse whose slowly spreading rhizomes form clumps that are vital in stabilizing seashore ecosystems, as well as withstanding hot dry summers and varied garden soils.
Blooms August – October.

Conjuring early morning summer skies, a thick light-catching haze of hushed pink inflorescences hovers just above broad bluish green blades that forge a compact upstanding foundation. This tailored grass earns its keep with rosy-gilded fall color, persistent bird-friendly seed heads and a versatile guise that abides drought, varied soil types, coastal conditions and pollution. Discovered at North Carolina’s Hoffman Nursery, ‘Summer Sunrise’ adds pizazz to mixed borders, rain gardens, ecological plantings and cut arrangements.

Panicum virgatum ‘Cloud Nine’ (G-0082)
Each $12.25
It’s not sky high, but ‘Cloud Nine’ does impart visions of grandeur as it rises into a massive, somewhat vase-shaped, blue-green form crowned by a mist of small inflorescences. Autumn brings golden tones to the foliage. This Panicum usually maintains its elegant shape through tough winter months, and is a dynamic partner with Salvia confertiflora for the rest of the season.

Panicum virgatum ‘Heavy Metal’ (G-0021)
Each $12.25
One of the most upright of the blue-leafed varieties, this Kurt Bluemel selection struts glaucous gray-blue foliage beneath airy pink-tinged blooms. Autumn brings warm pecan-brown hues to ‘Heavy Metal’s vertical stance, which looks especially dynamic when planted in swaths.
Blooms September–October
Size: 4' 0" – 5' 0" high x 3' 0" wide.
Hardy to zone 5.
This colorful, smaller statured Panicum makes its way into plenty of European gardens, but is sadly hard to find here in the states. Airy clusters of pinkish oat-colored inflorescences traipse upon firm upright stalks cloaked with dapper, glaucous bluish green blades that manifest rousing deep burgundy tones once the nights turn cool. A staunch versatile grass, ‘Heiliger Hain’s manageable size makes it well-suited for midborder positions, decorative containers or swathes in larger spaces.

Panicum virgatum ‘Northwind’ (G-0544)
Each $12.25
Claiming the coveted 2014 Plant of the Year award, ‘Northwind’s roots can be traced back to the railroad tracks near South Elgin, IL, where Roy Diblik collected some native Panicum seeds. Selected from those initial seedlings for its unique unwavering stature, this dashing straight-backed cultivar unleashes a narrow sky-bound clump of broad olive-colored blades with bluish green undersides. The gossamer textured inflorescences hover just above the leaves and are characterized by tiny yellow flowers plus purple seed heads. Unsung among ornamental grasses and the most markedly vertical of the Switch grasses, it lends intriguing winter architecture and possesses a tenacious bent that triumphs over drought, heavy downpours, varied soil conditions, pesky deer and foliar rust.

Prized for fantastic autumn color and impressive vertical accents, a narrow upstanding clump fashions slender grayish green leaves that broadcast dark maroon and violet shades in late summer. The dreamy cloud of finely cut haze-like purple-green spikelets bleaches to beige and persists into winter, while the compact long-lived foliar column wears a buff-tinged cold-weather coat.

Panicum virgatum ‘Rotstrahlbusch’ (G-0059)
Each $12.25
This exceptional vintage cultivar has withstood the test of time, touting the smallest, most upright foliar foundation with the brightest most enduring red blades of all our Panicum. Suave, fine textured silver-green blades, subtly blushed in late spring, ascend vertically and cushion a lovely diaphanous mass of branched pink-tinged flower panicles. “Red Ray Bush”, as it translates from German, begins broadcasting passionate fiery red foliage in August that ignites the late season border, while companions such as Aster ‘Raydon’s Favorite’, Sedum ‘Mr. Goodbud’ and Kniphofia ‘Yellow Cheer’ inject complementary color.

Celebrating long-lasting appeal and color galore, this exceptional Panicum ‘Heavy Metal’ and Panicum ‘Hänse Herms’ cross was chosen by Dr. Mark Brand from the University of Connecticut. Fantastic arching ribbons of foliage initially emerge in soft gray-greens, then in early summer, transmute a vibrant ruby-red, which heightens as the season progresses. Loosely arranged, broad tapered blades forge an upright textural clump renown for its unparalleled, richly hued fall finale, while hazy sand-colored inflorescences create winter interest, especially when overlaid with frost or snow.

Crowned by misty pinkish tan panicles, steadfast broad blue-green blades compose an upright and slightly arching, 8 ft. profile that swaggers a magnificent bearing even in winter, remaining tall through wind, heavy rain and snow. ‘Thundercloud’s handsome bird-friendly foliage and open blooms can grace a vase, flank a mixed border, serve as a screen, or stand-alone as a stately specimen in a stylized meadow.
