CALIFORNIA SAGEBRUSH (Artemisia californica )
California has many unique plant species due to its climate and a lot
of the plants have adapted well to our lack of rain and many months of
direct sunlight. One species that has done particularly well is
California sagebrush. With its needle like leaves, the sagebrush
does not lose nearly the amount of water through evapotranspiration as
plants with broader leaves like the sycamore. Sagebrush is a
shrub that is indicative of several habitat types, including coastal
sage scrub and chaparral. This plant tends to grow in dry
foothill communities, like Chino Hills State Park. It is common to see this plant growing on north and
western slope in the Park. Additionally, when lands have been
disturbed, sagebrush is often one of the first plants to be used for
rehabilitation of sites.
Sagebrush is also a very fragrant plant and if you
gently rub the leaves between your finger tips -- it smells like one of
the spices you may add to your spaghetti sauce! In fact, before
Native Americans went on a hunt they would use sagebrush to camouflage
their own smell and the animals being hunted would not smell them coming.
Though not a true sage, this plant is also used historically to cure
coughs and colds. Unless you have training in ethnobotany or
medicinal uses in plants we do not recommend ingesting any plants.

LEMONADE BERRY (Rhus integrifolia)
Another member of the chaparral community is lemonade berry. Its
normal range is from Santa Barbara to Baja California and has an
extensive range throughout western Riverside County, including Chino
Hills State Park. Lemonade berry tends to grow in canyon bottoms
on north facing slopes. Its round shape can grow as tall as 24
feet but is normally around 10 feet.Its
leaves are also quite well adapted to Southern California's climate.
Two adaptations include the curved shape of its dark green leaves.
This shape provides shade of sorts and therefore the plant doesn't
lose as much water through its leaves via evapotranspiration as some
plants. Its second adaptation is the waxy feel to the leaves.
This waxy coating also helps hold moisture in, just like chapstick
holds moisture in on our
own lips.
Native Americans used this plant to flavor drinks,
unfortunately this plant is a diuretic. Therefore we do not recommend,
unless you are specifically trained in the field, to not attempt eating
this plant or its berries. Remember if the plant is in the Park - it
is protected.

PURPLE SAGE (Salvia leucophylla)
Chino Hills State Park also has its fair share of other fragrant sages
as well. Purple sage, which is normally found throughout
Southern California down to Baja California, are generally found in
elevations from 100 feet to 2600 feet above sea level. As a
shrub, it tends to reach a maximum height of five feet and prefers dry
open hillsides.
Called purple sage, for its purple aromatic
flowers, these flowers draw insects and birds to feed on the nectar.
Purple sage blooms several times a year and is a very hardy plant
which is drought tolerant. For that reason, purple sage is one
of the favored xeroscaping plants, since it requires minimal
maintenance and very little water.
Native Americans used this plant during ceremonies and
rituals.

WHITE SAGE (Salvia apiana)
White sage is an evergreen perennial shrub found throughout
southwestern U.S. and northwestern Mexico. It is one of the
predominant plants in the coastal sage scrub habitat. It, like other
sages, is well adapted to our hot, dry climate. A few of its
unique adaptations include small hairs on its leaves. These
hairs act the same way our own head of hair acts in the sunlight, it
protects us from the sun, thereby limiting its loss of water by keeping
the leaves cooler. In addition, its white colored leaves reflect
the sunlight, which also limits the plant's loss of water.
This plant requires well drained soil, full sun and
very little water. Like the other sages mentioned on this page,
white sage is also used widely in native garden displays.
White sage is common throughout the Park and is often times found on
the hillsides and along trails.
Native Americans used the seeds of white sage as a
component to creating flour. Other uses of the plant were to cleanse
the eye, shampoo the hair, and was also used as a tea. This plant is
sacred to Native Americans and even today smudge wands are created to ward
off evil spirits when the leaves are bundled and burned. Again,
plants in the Park are protected and we ask that you not remove them from
the Park. In addition, do no attempt to ingest
this plant.

BLACK SAGE (Salvia mellifera)
This perennial shrub grows to about seven feet tall and is another
predominant plant of the coastal sage scrub community, but is also
found in lower chaparral communities as well. Black sage is dark
in appearance especially during droughts and is found throughout
California and Baja Mexico. As with the other sages, it is often
times used in native garden displays as it is well adapted to our hot
and dry climate. This sage is well adapted to a variety of soil
types from sandstone to gabbro to basalt.
This shallow rooted plant, during times of drought, will curl up its
leaves to retain water instead of dropping its leaves. Many
birds and small animals use black sage for nesting or as cover from
predators. Often times black sage is used to revegetation
disturbed areas as it is drought tolerant and grows rapidly.
Like the other sages, black sage is susceptible to air pollution and
is a good biological indicator of air pollution in Southern
California.
Native Americans used portions of this plant to ground
it into a meal for baking. Its crushed leaves were often used as a
spice to flavor some of their meals. Again, we do not recommend,
unless you are specifically trained in the field, ingesting
this plant. Remember if the plant is in the Park - it
is protected.

CHAPARRAL
Chaparral is a shrub land ecosystem that does particularly well in
Southern California's hot, dry climate. It is also found in similar
locations, such as the Mediterranean, central Chile, South African Cape
and Australia. Like other plants we've described, chaparral is word
borrowed from the Spanish language -- "chaparro." Chaparro means small
dwarf evergreen oak.
In normal conditions chaparral grows in thick densely growing ever
green scrub oaks and other drought resistant plants. For the most
part its tightly knit plants provide protection for smaller animals trying
to escape large predators. These small animals, like rabbits,
squirrels and raccoons use the chaparral for refuge.
Like other mentioned plants and plant communities,
chaparral has endured significant fires. Under the right conditions,
chaparral benefits from fire with certain frequency, severity, intensity
and depends on the season. Generally due to its high oil content,
when chaparral burns dark black smoke is the indicator. Normally,
chaparral requires 30 years of leaf litter accumulation before they will
reproduce successfully. With fire intervals of every 10-15 years, or
even more frequently, the chaparral plants suffer and may be replaced with
non-native grasses.

LAUREL SUMAC (Malosma laurina)
Laurel sumac is a large evergreen shrub that ranges in size from 10 to
15 feet in height. One particular trait that helps identify this
plant is that its leaves have a red vein and its stems are also red in
color. Its leaves are well adapted to our hot climate and are taco shaped.
This shape helps keep portions of the leave in the shade, to limit the
amount of water lost through evapotranspiration.
This plant produces a cluster of white flowers that remain on the
plant long after they have dried out. Laurel sumac is commonly found
in coastal sage scrub and chaparral ecosystems. It also prefers dry
ridges and canyons below 3000 feet. When settlers first arrived in
the area, they would use the presence or absence of laurel sumac as an
indicator of the temperature. Laurel sumac is very susceptible to
frost and therefore citrus growers used it to determine if their crops
would do well in the area or not.
Native Americans used portions of this plant to ground
it into a meal for baking. Its crushed leaves were often used as a
spice to flavor some of their meals. Again, do not attempt to
eat
this plant as it is a Park resource.
