‘Stripe It Rich’ Japanese ‘Carousel’ little forest grass bluestem

think grasses suffer from lumping. I’m guilty of it myself, many times ending a list of companion perennials with the phrase “and some ornamental grasses.” I This gives the impression that all grasses are the same and interchangeable. They’re not, and when we trialed dozens of some of the newest and most popular types at the Chicago Botanic Garden, the differences between them became even more clear. While I still feel like a novice where grasses are concerned, my appre­ ciation has deepened as I’ve opened my eyes to their uniqueness. Rather than treat­ ing grasses as footnotes in the garden, I now see them as distinctive . Grasses are unsung heroes—often perceived as sidekicks to flashier perennials or relegated to the background in a landscape. But certain grasses are so much more than worka­ day plants, and they deserve a prime spot where their notable qualities can be seen and heard. These select grasses are a sensory delight of sight, sound, motion, and smell. The following top performers earned excellent marks in our trial because of their incredible architecture, beautiful , and unfaltering performance despite weather inconsistencies.

These grasses put the competition Top performers to shame when it comes to looks, behavior, and toughness.

Despite being categorized as “invasive” in 25 states, the District of Columbia, and Ontario, miscanthus (Miscanthus sinensis* and cvs., Zones 4–9) continues to be a popular nursery plant. Many still insist that some cultivars are sterile and do not set viable . To put that theory to the test, scientists at the Chicago Botanic Gar- ‘Autumn Light’ • Viable SEEDS den conducted an invasive- trial and here’s what they found.

▶ Seedlings popped up despite being quarantined. From 2006 through 2010, 34 miscanthus were grown in their own separate trial beds and monitored for vigor, bloom period, and production. It didn’t take long to see an increasing number of seedlings carpeting the trial plots and adjacent landscapes each spring, although it was impossible to know which of the so-called “sterile” plants were reseeding.

▶ Tests revealed the viability of each ’s seed. In October 2010, inflorescences from each of the 34 plants were X-rayed to see if embryos were present in ‘Hinjo’ • NO SEEDS the seeds (presenting as well-formed, solid white orbs on the X-ray, photos, right).

‘Red October’ big bluestem For fall color, nobody does it better than ‘Red October’ big bluestem (Andropogon gerardii ‘Red October’, USDA Hardi- ness Zones 3–9). Dark green leaves tipped in burgundy turn full-on burgundy in early fall. As if this color isn’t luscious enough, it changes to brilliant scarlet after a few frosts. The turkey-foot red-purple flowers with orange anthers are borne at the end of red-bronze stems in summer—a color bonanza at every turn. So far, the plants are standing proudly at 6 feet

anielle D anielle tall and 3 feet wide. ‘Blonde Ambition’ blue grama (Bouteloua gracilis ‘Blonde Ambition’, Zones 4–9) was an unexpected surprise in the first year of the trial. It not only was showy but also reached its full size (37 inches tall and 42 inches wide) in just one summer. A profusion of chartreuse flowers blanketed fine-textured blue- green mounds in midsummer. The blonde seed heads resem- ble mini pennants fluttering over the plants; they remained intact through winter, providing color and texture—which was ‘Blonde Ambition’ blue grama another surprise. The species is cold hardy and adaptable to a range of soil types; it even excels in our green-roof garden in just a 6-inch depth of growing medium. We’re hoping ‘Blonde Ambition’ proves just as hardy. ‘Windbreaker’ big sacaton (Sporobolus wrightii ‘Wind­ breaker’, Zones 5–9) is a recent introduction from New . With humble beginnings as a utilitarian plan (it was developed as a wind barrier for commercial vegetable fields in the West), ‘Windbreaker’ has a bright future in gardens. It’s a big plant, though, with stems rising 8 to 10 feet tall and 6 feet wide over time. In the first year of the trial, it was 68 inches tall and 58 inches wide, so it’s well on its way to its full size. Touted as a native substitute for gigantic pampas grass (Cortaderia selloana* and cvs., Zones 7–11), ‘Wind- breaker’ provides all that drama—and more. Gray-green leaves form a generous mound with large pyramidal green flower clusters soaring high overhead in summer. Big sacaton is not short on positive cultural attributes, either: It’s tolerant and adaptable to high-alkaline, saline, and poorly ‘Windbreaker’ big sacaton drained soils. Big sacaton is an important conservation and plant in the Southwest and a little-known relative of SOURCES prairie dropseed (Sporobolus heterolepis, Zones 4–9).
