Poaceae
Form: Strongly vertical, clump-forming warm season
grass to a height of 8 feet and spread of 36 inches
Foliage: ¼ inch to 3/8 inch wide, green to green-blue,
with excellent coppery orange-red fall color
Flowers: Terminal, red at emergence and darkening with
age, and resemble a turkey foot; clustered 2 to 4 on the ends of short
peduncles mostly enclosed by sheaths.
July
Seedheads: Retain shape and color through winter,
turning a pleasing tan and waving in the winter wind
Culture: Full sun to very light shade (clumps will
become more open with a tendency to lean).
Native to average to moist tallgrass prairies; also tolerant of drier
urban conditions. Cut to ground in late
winter or when snow load is too heavy to support stems.
Uses: Specimen; backdrop for shorter, rounded
grasses; naturalized areas, prairies, seasonal screen, hot spots, multi-season
interest, cut material, bioswales.
Companions: other native plants; coneflowers, Russian
sage, asters, false sunflower, penstemons
Propagation: Divisions (extremely long root system) or
seed
Cultivars: `Pawnee’ - shorter, reaching 5 to 6 feet; light red fall
color. Becoming more readily available
commercially
`Silver
Sunrise ’ - almost steel-blue foliage with horizontal bands of
pale yellow and gold, large numbers of inflorescences with silver and gold
tones; extremely floriferous with a silver and gold; slightly shorter and more
dense than the species; a hybrid.
Difficult to propagate. A hybrid
selection of sand bluestem
Sideoats Grama
Bouteloua curtipendula
Poaceae
Form: Clump-forming, warm-season native; rounded,
mounded form to a height and spread of 18 inches; up to 36 inches in flower
Foliage: Light green to blue-green, rather narrow
blades, quite graceful and uniform, fine texture
Flowers: On slender, arching, wand-like stems above
the foliage beginning in June or July and occurring throughout the summer;
individual spikelets are held at a wide angle along the flowering stem, mostly
on one side

Feather Reedgrass
Calamagrostis x acutiflora
Poaceae
Form: Cool-season grass, forming strongly upright
clumps to a foliage height of 36 inches and spread of 48 inches; bloom height 4
to 5 feet
Foliage: Bright green leaves emerge very early in
spring, quickly forming welcome green clumps that last well into fall; blades
up to 1/2 inch wide. Light tan fall
color; medium-fine texture
Flowers: Vertical, loosely ovate, silvery, each
inflorescence up to 12 inches long in June.
This is one of the earliest ornamental grasses to flower.
Seedheads: Tight, narrow form; turning tan by late
summer, effective until mid-winter. This
grass will withstand severe rain and wind and straighten up again
Culture: Full sun to part shade (six hours of sun per
day). Tolerant of most well-drained
soils, including construction sites; drought tolerant once established. Allow
seedheads to stand until late winter or very early spring; cut to within six
inches of base before growth initiates.

Uses: Specimen, screen, backdrop in hot sites or borders;
multi-season interest.
Companions: other ornamental grasses with contrasting
shapes, coneflowers, Russian sage, butterflybush, Helen’s flower, shrub roses,
veronica, sedums, asters, almost all perennials
Propagation: Division in early spring
Cultivars: `Karl
Foerster’ - the standard against which the reedgrass cultivars are
judged
`Overdam’ - beautifully
variegated, with a broad cream or white stripe (somewhat variable, depending on
source) in each leaf; less vigorous and shorter; also tolerates more shade but
won’t bloom as well
`Avalanche’ - more
variegated than ‘Overdam,’ but consistently white instead of cream
Other Species: C. strictus
- native
Korean Feather Reedgrass
Calamagrostis brachytricha
Poaceae
Form: Clump-forming, each clump an upright vase;
foliage height and spread 48 inches; 5 feet in bloom
Foliage: Arching, bright green blades to ½ inch wide;
no appreciative fall color; medium texture
Flowers: Lanceolate, feathery, reddish-purple
inflorescences to 12 inches long; one of the latest grasses to bloom, opening
in September
Seedheads: Almost translucent silvery-white; beautiful
when backlit; effective for 2 to 3 months and often persisting through winter
Culture: Full sun to part shade (six hours of sun per
day). Tolerant of most well-drained
soils, including construction sites; drought tolerant once established. Allow
seedheads to stand until late winter or very early spring; cut to within six
inches of base before growth initiates.
Division is rarely necessary unless additional plants are desired
Uses: Less well-known than other hybrids and
species; an outstanding ornamental grass for use as specimen, mass, backdrop in
hot spots or borders; multi-season interest, texture and movement.
Companions: late asters, tall maidengrasses, sedums,
Joepye-weed, ‘Becky’ daisy, shrub roses, penstemon, coneflowers
Propagation: Will reseed occasionally; divide in spring
Northern Sea-oats
Chasmanthium latifolium
Poaceae
Form: Warm-season clump-former, native to moist
thickets and wooded slopes in eastern North America; upright, uniform vase
shape in sun, more open and arching in shade; foliage height and spread 18
inches, bloom height 36 inches
Foliage: Deep, bright green on strong stems, blades up
to ¾ inch wide and 8 to 12 inches long. Seaoats has strong stem foliage, giving
it a dense appearance and different texture than many clump-formers. Emerging
seedlings look like oats.
Flowers:
Oat-like spikelets, arranged almost like the overlapping scales of a fish;
dangling along one side of gracefully arching stems; June
Seedheads: Green turning to tan or straw in winter and
remaining attractive until spring; excellent cut material
Culture: Full sun to full shade, wet or dry soils of
poor to average fertility. Drought tolerant once established; also tolerant of
consistently wet areas. Reseeds itself
with abandon, and seedlings are tenacious in their hold on the earth; will take
over a garden in a matter of two or three seasons unless seedheads are removed
before they shatter.
Uses: Massing, edger, specimen, naturalized areas,
texture and movement in shade, cut material.
Companions: Hostas, cranesbills, low sedums, dwarf
asters, turtlehead, coralbells
Propagation: Seed
Canada Wildrye
Elymus virginicus (canadensis)
Poaceae
NATIVE
Form: Upright, arching form from rhizomes; height
and spread to 36 inches
Foliage: Narrow green blades; open and alternate on
stems
Flowers: Greenish

arching and turning tan; persistent
Culture:
Part shade to shade; moist soils; tolerant of a wide range of conditions
Uses: Naturalized areas, woodlands, wetlands
Propagation: Seed
Sand Lovegrass
Eragrostis trichodes
Poaceae
NATIVE
Form: Broad-spreading, warm-season clump-former,
rather slow to start until weather is quite warm; height and spread of foliage
30 inches and 36 inches; height in bloom 48 inches.
Foliage: Bright green, rather lax arching blades 1/8
inch to ¼ inch wide; tinges of red in fall.
Fine texture
Flowers: Airy, open panicles, reddish to pink-tinged,
on slender stems in late summer, produced in such abundance that the plant
appears to be covered by a wispy pink cloud
Seedheads: Also airy, tan, effective early but not
persistent because of the slender stem.
Rain, snow and ice will cause the stems to bend and break, with no
recovery
Culture: Full sun to a fair amount of shade but
becomes even less upright; sandy or loose soils of low to average fertility,
good drainage. Standing water or poor
drainage in winter in urban conditions will result in the death of this
grass. Allow to lean on surrounding
plants; remove seedheads in late fall to reduce seedling production and to
discourage unwanted inhabitants beneath the prostrate stems
Uses: Naturalized areas, texture and movement,
backdrop, prairies, wildflower gardens, habitat and food for birds.
Companions: butterfly milkweed, tall penstemons, little
bluestem, mountain mint, coneflowers
Propagation: Self-sows; seed or spring division

tufts or rounded clumps, to a foliage height and width of 12 to 15 inches; height in bloom 18 to 24 inches
Foliage: Steel blue and very striking, narrow,
slightly flattened and arching blades less than ¼ inch wide. Foliage maintains its color when plants are
placed in preferred conditions. Very
fine texture
Flowers: Wispy, upright panicles the same color as the
foliage, arching up and out in an open vase shape; not particularly effective;
June
Seedheads: Bleach to tan and fall over soon after ripening,
giving the clumps a less tidy appearance
Culture: Full sun to light shade; loam or sandy loam
soil of average fertility with excellent drainage. Intolerant of extended heat
and humidity, standing water in any season, open winters without snow cover,
consistent salt spray or foot traffic.
Shear in late winter to remove dead foliage. Plan on frequent
replacement
Uses: Small specimen, focal point; structured or
formal pattern in ideal conditions. Best
used with restraint, in locations where two or three plants can be replaced
without destroying the integrity of the planting.
Companions: pussytoes, thyme, Missouri primrose, purple
poppy mallow
Propagation: Seed; division for cultivars
Cultivars: `Elijah Blue’
- very steel-blue form to 10 inches; probably the most long-lived selection for

F. g. ‘Sea
Urchin’
Hakone Grass/Japanese Silver Grass
Hakonechloa macra
Poaceae
Form: Warm-season grass; gracefully cascading
blades; weakly spreading, rhizomatous habit resulting in small patches; height
and spread 15 inches
Foliage: Bright lime green, flowing, with blades
sweeping the surrounding soil; copper-orange in fall; fine texture.
Flowers: Subtle, small inflorescences held just above
foliage, not showy. June
Seedheads: Not effective
Culture: Part to full shade in cool, moist, fertile,
well-drained soils. This native of
Japan’s woodlands is of questionable longevity in the Northern Great Plains but
on the “must try” list of many gardeners.
Provide optimum conditions; do not cut back until growth has initiated
in spring to allow old foliage to protect crown. Old ‘restoration’ neighborhoods around small
ponds or intimate gardens seem to be the best conditions for this grass.
Uses: Provides the much-sought-after texture and
movement of grasses in shaded conditions; specimen near water feature,
boulders.
Companions: coralbells, brunnera, snowdrops, fernleaf
bleedingheart, toadlily, hostas
Propagation: Division, which is rarely necessary
Cultivars: Variegated cultivars include ‘Aurea’ or ‘Aureola,’
with gold bands parallel to margins; very desirable but less hardy
Blue Oat Grass/Blue Avena Grass
Helictotrichon sempervirens
Poaceae
Form: Low, spreading, clump-forming vase, to a
height and spread of 24 inches; 30 to 36 inches in bloom
Foliage: Evergreen, steel blue, the blades narrow and
sharply pointed
Flowers: Tan, open panicles, the individual flowers
loosely arranged toward one side of the curved stalk
Seedheads: Panicles turn warm honey brown, in strong
contrast to the blue foliage
Culture: Full sun to very light shade; loose,
well-drained soil of average fertility. Tolerant
of rocky, sandy, and alkaline conditions, as well as extended drought. Remove tattered foliage in early spring. Avoid standing water, over-irrigation, or
heavy fertilizer.
Uses: Formal edge or mass, extended season of
interest. An awesome, low input
grass.
Companions: ornamental oregano, blazing star, yarrow,
butterflybush, dwarf blue false indigo
Propagation: Seed, division
Japanese Bloodgrass
Imperata cylindrica var. koenigii
Poaceae
Form: Slowly rhizomatous, forming uniform patches of
upright, vertical foliage; height 18 inches, spread 24 inches or more. Not to be mistaken for the viciously
spreading tropical variety, even though its sale is prohibited in many states
Foliage: Emerges green with red tips in spring,
becoming progressively more red through the summer until it looks looking
finally like stained glass in autumn; blades ½ inch wide and evenly spaced (not
crowded or dense)
Flowers: Narrow, cylindrical inflorescence held above
foliage; occurs rarely; May
Seedheads: Not effective
Culture: Full sun to part shade, average loam or clay
loam soil; well-drained. Not tolerant of
low spots or standing water. Will spread rapidly in locations where it is
happy, but maintains its massed or clump appearance. NOTE: Imperata
cylindrica is on the noxious weed list in many southern states. In
Nebraska, reports vary as to its aggressiveness: some people can’t grow it at all, some people
can grow it but it won’t spread, some people think it is a thug.
Uses: Masses along pond edges, paths, where the
blades can be backlit; accent.
Companions: ‘Husker Red’ penstemon, ‘Ruby Glow’ sedum,
‘New Hampshire’ cranesbill, Siberian iris, plumbago
Propagation: Division
Cultivars: `Red Baron’ - the
most red, and the only cultivar to acquire
Melic Grass
Melica altissima
Poaceae
Form: Graceful, rhizomatous mass of open stems, to
a height and spread of 18 to 24 inches
Foliage: Rough and rasping to the touch, blades 1/8
inch to ¼ inch wide, less than 12 inches long; arranged on thin stalks
Flowers: Densely packed into terminal spikes, deep
purple-black in the cultivar; less so in the straight species. The spikelets are held away from the stem at
almost a 90 degree angle
Seedheads: Tan
Culture: Part shade to shade; average to moist
soils. This is one of the few grasses
that thrives in low light.
Uses: Woodland edge, shade garden.
Companions: coralbells, hostas, astilbe, wild ginger
Propagation: Seed, division
Cultivars: var. ‘Purpurea’
Maidengrass/Japanese Silver Grass/Eulalia Grass
Miscanthus sinensis
Poaceae
Form: Warm-season clump former with cultivars of
varying proportions, most more or less vase-shaped; foliage height 36 inches to
8 feet; spread 36 inches to 5 feet; bloom height varies with cultivar but is
usually not significantly taller
Foliage: Long, usually narrow blades with a distinct
midrib and usually sharp margins; blade width varies with cultivar from less
than ¼ inch to two inches. Bright green
to green with silver, white or gold variegation; reddish to tan winter
color. Foliage persists until removed in
spring. Medium-fine to medium-coarse
texture
Flowers: Slender racemes, digitately (like fingers)
clustered at their bases to form characteristic fan-shaped plumes. Color is often pinkish to silver, with some
selections showing more tan. July to
October, depending on cultivar
Seedheads: Fluffy extension of flowers, usually
silvery-white; some brownish and curled, persistent. The seedheads of many are
very ornamental, lasting well into the winter months and fairly stable in dried
arrangements.
Culture: Full sun to at least half shade (flowering is
reduced, but for late-flowering cultivars, this is not a deterrent). Tolerant
of a wide range of soils, from dry to wet or even briefly standing water. Very late to emerge in spring (particularly
the variegated, fine-textured cultivars like `Morning Light’) but vigorous once
the season warms. Drought tolerant once
established, although some moisture will promote healthier appearance. Allow to stand over winter; cut back to
within 6 inches of soil line in early spring.
Divide in spring, throwing away old dead centers and replanting viable
outer portions. Most older cultivars
bloom too late to produce viable seed in northern climates; however, newer ones
have been bred for earlier flowering, and the potential for seed
production is increased in these. Some are considered noxious weeds in southern
states.
Uses: Specimen, backdrop, mass, seasonal screen,
texture and movement, multi-season interest, dried material. The form and substance of this grass makes it
useful to provide scale in the landscape.
Companions: shrub roses, butterfly bush, blue false
indigo, goldenrod, blue globe thistle, coneflowers, yarrow, boltonia, tall
sedums, hardy hibiscus, balloon flower—nearly any perennial or grass with
substance, and most shrubs.
Propagation: Division

from orange to red to gold to tan.
Clumps are persistent through winter; medium-fine texture
Flowers: Racemes at the end of a slender peduncle at
the branching point of the stem; reddish; September
Seedheads: Fluffy, white, curled; beautiful when
backlit. Effective through the winter
months
Culture: Full sun and dry, well-drained soil. Tolerant
of extreme drought, alkaline and acid soils but not of high fertility or
moisture; does fine in average garden soils if well-drained. Do not add supplemental water. Cut back in early winter to discourage
excessive seedling production, or allow seedheads and foliage to stand until
early spring
Uses: Backdrop, specimen, naturalized areas,
prairie, wildflower garden, multi-season interest, cut material.
Companions: sedums, coneflowers, shrub roses, penstemons,
purple poppy mallow, yarrow, catmint, goldenrod
Propagation: Seed or spring division
Cultivars: `Blaze’ - originally developed as a forage plant, with strong
reddish tones in fall and winter
`The Blues’ - Clonal
cultivar, distinctly blue, taller, and tends to flop miserably. Division only
Indian Grass
Sorghastrum nutans
Poaceae
NATIVE
Form: Warm-season clump-former indicating
high-quality tallgrass prairie; broadly upright; foliage height and spread 42
to 48 inches; bloom height to 7 feet
Foliage: Green leaves to ½ inch in width, gold to
orange fall color turning tan with shades of red in winter and persistent;
medium texture
Flowers: Panicles brightly copper-colored, open and
loose in character but closing with age as seeds ripen; 4 to 8 inches long. They shine in the sun due to bright yellow
pollen sacs; August to September
Seedheads: Vaguely cigar-shaped, widening in the center;
copper-tan and showy through most of the winter; good cut material
Culture: Full sun to very light shade. Average moisture but will tolerate drought
once established; often found in roadside ditches in heavy, disturbed
clay. Cut to ground in late winter;
remove seedheads to control seedlings
Uses: Prairie, naturalized areas, specimen,
backdrop, wildflower garden, cut material, multi-season interest. Companions:
butterfly milkweed, joepye weed, coneflowers, goldenrod, Russian sage,
mallow, pitcher sage, sedums
Propagation: Seed (self-sows readily) or spring division
Cultivars: `Sioux Blue’ - very light blue foliage, upright form, yellow fall
color
`Bluebird’ - 3
to 5 feet tall with blue foliage, good yellow fall color
`Holt’ - Nebraska
selection, mostly for forage
‘Llano’
- Supposedly superior to ‘Sioux Blue,’ a better blue-foliaged selection from
New Mexico
Prairie Cordgrass
Spartina pectinata
Poaceae
NATIVE
Form: Wide-spreading, upright to upright arching
plant that spreads aggressively by rhizomes to a height in flower of 72 inches
or more and an indefinite spread
Foliage: Dark green leaves ½ to 5/8 inches wide,
glossy surfaces and smooth edges. Medium
texture
Flowers: Stiffly open terminal panicles, with the side
‘branches’ held almost perpendicular to the main stalk. July to August
Seedheads: Not effective
Culture: Full sun to very light shade in moist to dry
soil. Prairie cordgrass spreads much
less rapidly in dry conditions. Excellent upright choice for rain gardens. Cut
back in March.
Uses: Conservation plantings, erosion control,
habitat, large pond and wetland areas.
Companions: Swamp milkweed, joe pye weed, switchgrass
Propagation: Division
Cultivars: ‘Aureomarginata’ - yellow to gold variegation on
foliage; ornamental in managed water gardens
Prairie Dropseed
Sporobolis heterolepis
Poaceae
NATIVE
Form: Elegant, warm-season native; mop-headed mound
to a foliage height of 15 to 18 inches
and spread of 24 inches; bloom height to 30 inches.
Foliage: Very fine light green leaves 1/16 inch or
less in width, neatly arranged evenly around the center of the crown; fall
color can be a brilliant orange; winter tan and persistent
Flowers: Open panicles, 2 to 5 inches long on long
slender stalks above foliage in vase-like arrangement; not dense or numerous;
fragrant, with a scent like vanilla. May
take years to bloom; August to September
Seedheads: Delicate, tan, somewhat persistent into early
winter
Culture: Full sun to light shade; average to dry,
well-drained clay, loam or clay-loam soils.
Extremely drought tolerant once established; can be left in place for
decades without needing division or replacement. Cut to ground in late winter
Uses: Border, edger, specimen, textural contrast,
fragrance, cut material, prairie, wildflower garden.
Companions: penstemons, sedum, poppy mallow, Missouri
primrose, short goldenrod cultivars,
butterfly milkweed
Propagation: Seed, but it is difficult to germinate
Giant Sacatoon
Sporobolis wrightii
Poaceae
Form: Strong vase-shaped mound of foliage to a height and spread of 36 inches; bloom height 6 to 7 feet
