Indian ricegrass (
Oryzopsis hymenoides)
is a
perennial cool-season
bunchgrass.
It is native to western North America east of the Cascades from British Columbia
and Alberta
south to
southern California
, northeastern Mexico
, and
Texas
. In the wild it typically grows 4 to 24
inches (10 to 61 cm) tall and 8 to 12 inches (20 to 30 cm)
wide.
It grows in a variety of habitats from desert shrub up to
ponderosa pine forests. It can live in soils
from sand to clay, but it does particularly well in sand, where it
is the dominant grass growing with
sagebrush and may occur almost unmixed with other
plants.
In the past, the grass was a staple food of
Native Americans,
especially when the
maize crop failed. Seed of
the ricegrass was gathered and ground into meal or flour and made
into bread.
It is an important food for livestock and for wild
grazers such as
bison,
desert bighorn sheep,
elk,
mule deer,
pronghorns, and
jackrabbits. For some of these species it is
especially vital in late winter, as it produces green shoots
earlier than other grasses. The seeds are heavily consumed by many
rodents and birds, notably
mourning doves.
This tough grass is known for its ability to reseed and establish
itself on sites damaged by fire or overgrazing. Much germination
occurs in years with wet Aprils. It is grown in
xeriscape—
cultivars are
available—and will become quite large if given sufficient space.
The open, spangled appearance when in flower or fruit is very
attractive, especially in backlight. The flower stalk is commonly
used in dry
flower
arrangements.
It was officially recognized as the Nevada
state grass in 1977 and as the
Utah state grass in 1990.
The Utah Section of the
Society for Range Management
began campaigning for a state grass in the mid-1980s, and after
studying many species the field was narrowed to four candidates,
Indian ricegrass,
bluebunch
wheatgrass,
galleta grass, and
Great Basin wildrye. Indian ricegrass was then
selected. The state-grass bill was introduced by Senator
Alarik Myrin, a member of the Society, in
1989.
