It shows potential as a ground cover or turf. The restoration,
forage, and habitat value of A. hallii is undetermined.
Bouteloua
gracilis - Blue Gramma:
Characteristics:
B. gracilis is a tufted perennial bunchgrass that
has a full-grown stature of 1 to 2 feet in height and
1 foot in width. Its foliage is green and it has a root
depth of 16 inches. Its flowering stems bloom in early
summer and have a red hue in the beginning of summer that
bleaches to white from sun exposure. Grows during the
warm-season and has a moderate life span.
Conditions: This bunchgrass tolerates regular water
but is also drought tolerant. It can live in full sun
and grows in sandy, loamy, or alkaline soils. B. gracilis
can tolerate mowing and foot traffic.
Geographic
location: B. gracilis finds home on plains in Wisconsin
to Manitoba and Alberta, south to Arkansas, Texas, Southern
California and into Mexico .
Applications:
B. gracilis forms a very coarse turf substitute
that, after established, is a fairly level low-water-maintenance
lawn if mowed. Its florets and seeds are in a distinct
ornamental structure that is appealing in a yard. After
the first year of growth B. gracilis will overcome
weeds to provide native re-vegetation. B. gracilis
is also great for spring grazing.
Carex
pansa - Dune Sedge:
Characteristics: C. pansa is a very small
creeping dune plant that grows to be 4 inches tall and
3 1/2 inches to 3 feet wide. This perennial has fine green
leaves that make small tufts when healthy. The green florescence
blooms in late spring and can remain throughout the year.
C. pansa is a cool season grower that spreads by
rhizomes.
Conditions:
C. pansa favors partial shade or full sun and tolerates
seasonal flooding. It prefers sandy or well-drained soil.
Foot traffic and mowing is all right; however, mowing
is not necessary.
Geographic
location: C. pansa is found in coastal woodland
understory. Even though it is a coastal species it adapts
well to other inland conditions. It is found in California.
Applications:
C. pansa makes an excellent lawn substitute that
deer will not eat. It is also used for dune restoration
and provides habitat cover for many critters.
Deschampsia
caespitosa
-Tufted Hairgrass: Characteristics:
D. caespitosa is a densely tufted bunch grass that
reaches heights of 1 to 4 feet and a width of 2 feet.
It has narrow dark green leaves that are stiff and rough
to the touch. It maintains its green color in mild climates.
This bunchgrass has a very attractive, airy flower stalk
that is variable in color, showing purple, silver, green,
or gold. Feathery inflorescence show up in late spring
or early summer. It grows in spring and summer and if
allowed to go dormant it will turn a pale tan. This perennial
is long living and spreads by rhizomes.
Conditions:
D. caespitosa is flexible to weather conditions
because it is tolerant to water, including salty water,
as well as drought. Thrives under high shade canopy where
it is humid; however, it does best in semi-shade. It prefers
heavy soils, but can tolerate sandy soil. D. caespitosa
tolerates mowing and foot traffic.
Geographic
location: D. caespitosa is widely scattered
in different environmental conditions and geographic regions.
Commonly found in mountain meadows but also occurring
at lower elevations and along the coast near springs,
bogs, and marshes. In California it is found from the
high canopied pine forests of the coast to higher elevations
in the Cascades and Sierras. It finds habitat east to
the Rocky Mountains and Atlantic coast. It also exists
north through Canada up to Alaska.
Applications:
D. caespitosas seed heads make a beautiful,
graceful impression that is complimentary to surrounding
water features. It acts as a natural lawn or as a footpath
and selections of the species can be used for sports fields
including soccer, rugby, and golf. It is valuable for
erosion control and re-vegetation around water areas such
as ponds, streams, ditch banks, waterways, marshy areas,
swampy pastures, and alluvial areas. D. caespitosa
is an important forage grass in the West that provides
good food and cover for animals. Livestock relish it,
and if managed properly, will respond well to grazing.
Festuca
californica - California fescue:
Characteristics: F. californica is a perennial.
Grows in loose clumps that reach 2 to 5 feet high and
a full-grown width of 1 to 2 feet. It has blue-green or
blue-gray leaves that maintain their color throughout
the year. In late spring to early summer feathery flowers
bloom from the crown. The flower spikes that are initially
green change to purple and finally turn a rich yellow.
Its root depth stretches to 8 inches. F. californica
is long lived and grows in the cool season.
Conditions:
F. californica does well in sun or partial shade
and tolerates drought in cooler climates. F. californica
can withstand a dry environment or extreme frost. F.
californica is adapted to various soil types including
serpentine soils but does need good drainage. F. californica
cannot tolerate regular foot traffic; however, it can
be mowed.
Geographic
location: F. californica is native to open dry
ground, chaparral slopes, and woodlands in the coastal
mountains from Oregon to Northern California. It also
grows west of the Sierras and in the Coast Range from
Santa Barbara to Oregon at 1000 to 5000 feet.
Applications:
F. californica is a striking, wiry, accent plant,
can be used in landscapes as a groundcover, turf, focal
point, or in groups for dramatic emphasis. Used for erosion
control to stabilize or restore disturbed sites. In restoration
it can benefit from association with a nurse crop, such
as brome or Elymus, since it is slow to establish. Once
it is established it can be expected to provide long lasting
benefits for erosion control, habitat value, fire resistance,
and as a striking aesthetic display. It is excellent for
habitat value, providing good wildlife food and cover.
As forage F. californicas use is limited
to early growth stages.
Festuca
Point Joe - Point Joe Fescue :
A bunch grass well suited for a
water-wise lawn. Grows well in poor soil and drought conditions.
1 foot tall round clumps and throws 2 foot tall seed heads.
Grass is blue in color and great for coastal landscapes.
For a manicured lawn, mow to 4".
Festuca
idahoensis - Idaho Fescue:
Characteristics: F.
idahoensis is
a densely tufted bunchgrass grows in clumps that are 10
inches wide and 1 to 3 feet tall. The color of its foliage
ranges from blue-green to silveryblue. F. idahoensis
has tall culms with loosely bound panicles. Its yellow
flowers bloom in early summer. It is generally fine-leafed;
however, some blue-green forms occasionally show a coarser
texture. It goes dormant in summer until the first rains
of the fall and grows in the cool season. Spreads slowly
by seeds and has a root depth of 14 inches. F. idahoensis
is a relatively long-living perennial.
Conditions:
F.
idahoensis can
withstand a dry environment or extreme frost. It will
grow in most all exposures to sun. F. idahoensis
will tolerate drought and poor soil conditions and is
moderately tolerant to cool, wet soils. It can survive
foot traffic and rare mowing.
Geographic
location: F. idahoensis grows in open woods
or rocky slopes and is widely daptable from British Columbia
to Alberta, all the way south to central California and
Colorado.
Applications:
F. idahoensis is excellent for landscape applications
where soil conditions are poor as a fine-leafed groundcover;
turf substitute; ornamental; or natural meadow. It is
also used as a cover crop in orchards and vineyards because
of its lack of water competition with the economic crop,
as well as its ability to suppress weeds while keeping
the soil structure open. Provides erosion control while
improving soil structure. Acts as superb nutritive forage
for all livestock when it is both green and cured. F.
idahoensis is highly palatable for livestock and can
be used as a component in pasture renovation.
Festuca
rubra - Red fescue:
Characteristics:
F. rubra is a loosely tufted perennial bunch grass
that grows from 8 inches to 2 feet tall. This grass has
tall culms and beautiful fine-leafed dark green blades
when watered. It has flowers that are pale green with
an occasional purple tinge, which bloom in mid spring.
F. rubra is long-lived, growing in the cool season
of spring and fall while spreading by rhizomes.
Conditions:
F. rubra is one of the most shade-tolerant of quality
turf grasses. It flourishes best with cool summers and
a damp growing season. It requires partial shade and irrigation
in hotter climates. This bunchgrass has the ability to
withstand a range of conditions including extreme frost,
moist soils, or dry areas. It needs good drainage but
is adaptable to a wide range of soils such as saline or
low fertility soils. For a nice lawn it takes well to
occasional mowing and foot traffic.
Geographic
location:
F. rubra
is found in bogs, meadows, and marshes throughout California
and in the cooler parts of the Northern Hemisphere to
around 8000 feet.
Applications:
F. rubra
presents a graceful windswept look when allowed to grow
to its maximum height and is especially dramatic as hillside
cover where it gives a fluid impression akin to a water
cascade. For those wishing to escape the tyranny of the
maintenance requirements of the standard lawn, it makes
a wonderful natural looking lawn or groundcover. Mixed
with other grasses and wildflowers it can be used as the
base for the creation of a classic natural meadow. Drought
avoiding selections are also useful as a cover crop in
vineyards and orchards; for buffer zones and rough areas
on golf courses; and for use in stream bank and riparian
applications. F. rubra is useful for erosion control,
soil conservation, weed competition, and revegetation.
Some examples of restoration uses include hillside stabilization;
waterway banking; and highway re-vegetation. This grass
is valuable forage that stays green after frost, remaining
good throughout fall for foraging.
Koeleria
macrantha - Junegrass:
Characteristics:
K.
macrantha is a
tufted perennial bunch grass approaches 18 inches in height
and 4 to 7 inches in width. It has a low stature and fine
appearance. K.
macrantha
has green ribbon-like leaves and glossy spike-like flower
stalks with yellow seed heads that bloom in late spring.
It is long-lived, growing in spring and fall and spreading
by rhizomes.
Conditions:
K.
macrantha
prefers hot summers without water and can tolerate partial
shade. K. macrantha is widely adapted, living in dry,
thin, rocky, sandy, or saline soils of low fertility.
It is low maintenance but can be mowed. Some selections
of K. macrantha can tolerate regular foot traffic.
Geographic
location: K. macrantha is found in the prairie,
open woods, and slopes throughout North America from Ontario
to British Columbia, south to Delaware, Missouri, Louisiana,
and California as well as in much of the temperate world
below 11,000 feet.
Applications:
K. macrantha is great for lawns or native meadows.
We have two selections, Los Padres, a native
selection, which grows to full height, and a low growing
selection, Barkoel, selected from northern
Europe, which is bright green, slow-growing and shows
tremendous potential for a drought tolerant, low maintenance
lawn and for use on water-conscious golf courses. Used
for re-vegetation, it acts as an early successional species
in very dry sites that protects later successional species.
K. macrantha makes good early spring and fall (after
curing) forage that is relished by livestock and wildlife.
Melica
californica - California Oniongrass:
Characteristics: M.
californica is a perennial
that can be densely or loosely tufted and grows 2 to 4
feet tall and 4 to 7 inches wide. Its leaves are bright
green with a delicate appearance. Its flowering culms
are silvery and ornamental, arching horizontally from
its swollen, onion-like base. The white to purple inflorescence
blooms during the summer. Growing in the cool season,
it goes dormant in the summer resisting efforts to revive
with water. It is short-lived and has rhizomatous roots
that grow well once established, with accelerating growth
in the second year.
Conditions:
M. californica likes moist environments and tolerates
a range of sun exposures from full sun, partial sun, to
full shade. It does well in sandy, clay, or serpentine
soil. M. californica tolerates mowing but not foot
traffic.
Geographic
location: M. californica is common on oak covered
north slopes, gullies covered with Baccharis, canyons,
foothills, mountain meadows, rocky woods, and occasionally
chaparral areas. Common associated plants are Mimulus,
Ferns, Lonicera, and Ribes. It is found at low to middle
elevations, below 5000 feet, in California and Oregon.
Applications:
M.
californica can be used
as a winter lawn that requires little water and maintenance.
M. californica is also used in moist rock gardens
or shade gardens. M. californica is small but can
add balance and finish to a native garden. It is useful
as a component of cover crops in vineyards and orchards,
subsoil slips, and road cuts. As a component of restoration
mixes it adds a bright green seasonal appearance and diversity
of habit, especially for difficult rocky and dry sites.
This nutritious forage is very palatable to livestock
and deer. Birds find its seeds to be delectable.
Poa
secunda - Pine bluegrass:
Characteristics:
P.
secunda is a
very attractive, lowgrowing, perennial bunch grass. Growth
form ranges from small tufts with only one or two erect
culms to large bunches up to 1 foot in diameter. Its height
varies from 20 to 40 inches. It has soft foliage and an
attractive flower and seed head that matures in May. P.
secunda is a cool-season grower that will go dormant
during the summer and after flowering at lower elevations.
In the mountains or cool sites it will continue growing,
remaining green despite its tendency to summer dormancy
and the availability of water. It is relatively short
lived and has a dense shallow root mass.
Conditions:
P. secunda can tolerate full sun and partial shade.
It is very drought tolerant and does not like water after
flowering. It grows well in rich clay loam soils but is
most often found on dry, rocky, or sandy soils that provide
good drainage. It is also adapted to thin soils and subsoil.
It requires mowing well and can tolerate minimal foot
traffic.
Geographic
location: P. secunda is found from sea level
to high into the mountains. It is very adaptable to many
habitats such as semi-desert, ridge tops, flats, slopes,
meadows, and open timberline. P. secunda can be
found in these habitats from southeastern Alaska across
to southern Canada, throughout the western and Great Plains
states to Arkansas and the Great Lakes region.
Applications:
P. secunda provides a transition, perhaps in prairie
or dry meadows, between natural habitat and lawn. It also
shows promise as a low-water using turf alternative. Since
at lower elevations it will go summer dormant, despite
the availability of water, it is thus excellent for use
as a cover crop in vineyards and orchards. It is a great
cover crop alone or in conjunction with Festuca idahoensis
and Festuca rubra Molate. A fine choice for
use in re-vegetation and restoration situations, where
water is unavailable such as for use along road cuts and
fills sites. It prevents the establishment and spread
of noxious weeds as well as providing exceptional erosion
control. It provides excellent, nutritious forage in the
summer, depending on location, for cattle, sheep, horses,
pronghorn, elk, mule, deer, small mammals, small non-game
birds, and upland game birds.
