Grasses
"How can you recognize a grass?"
"Sedges have edges and rushes are round,
Grasses have nodes all the way to the
ground."
Grasses have long, narrow
bladed leaves that join the stem with a sheath. Grasses have rounded, hollow
stems with nodes or joints all the way to the ground. Grasses bloom in
spikelets of tiny greenish, brownish, or reddish flowers on stems that
reach above the grass blades. These flowers are wind pollinated during
winter or spring days. Grass seeds form fruits called grains which are
harvested by people or animals for later use or the seeds hitchhike with
barbs or stickers seeking new homes to germinate more grasses.
Arundo (Arundo donax)
Commonly known as Giant Reed or Wild Cane,
this invasive weed is overtaking Monterey County's natural riverside vegetation.
This North African perennial grass species crowds out native riparian species
while at the same time restricts water flow. Arundo spreads when its rhizomes
are broken from floods or equipment use.
Bunchgrasses
Poaceae. Grass Family
-
Purple Needle Grass (Nassella pulchra)
-
California Fescue
(Festuca californica)
-
Tuffed Hair Grass (Deschampsia caespitosa)
-
Western Ryegrass (Elymus glaucus)
Native California grasses are perennial
bunch grasses which can reach 200 years old with a 25 foot deep root system
holding the soil and creating an underground ecosystem. When grazing animals
were imported by Europeans, they brought the annual seeds of European grasses
mixed with oats and other implements. Gradually, the bunch grasses were
weakened by grazing animals and the annual grasses took over as the "weeds"
that now cover our fields with green carpet in the winter and brown in
summer.
Pampas/Jubata Grass- (Cortaderia jubata
and Cortaderia sellowana)
Pampas grasses, ornamentals native to
Argentina and Chile, are best known for their tall seed plumes and razor
sharp leaves. They quickly establish themselves in road cuts, hillsides,
gullies, and other disturbed areas. It is critical that these plants be
controlled prior to seeding because each flower (plume) stalk produces
up to a million seeds. Pampas grass evolved many millions of years ago
during the last ice age. It had to endure the harsh weather and large grazing
animals like the Wooly Mammoth.
Forbs
Forbs are the name given to a group of plants
that do not have woody stems or leaves and structures like grasses.
Many of these plants are annuals, which mean they die each year
and rely on their seeds to germinate and grow to become next years plants.
Cobweb thistle -(Cirsium occidentale)
Asteraceae. Sunflower family
Not all thistles are bad. The cobweb thistle
is a native thistle to California and is a favorite of many native pollinators.
Cobweb thistle is an annual plant that has a brilliant reddish purple flower
in the summer and dies in the fall. The cobweb thistle drops its seeds
from only 2-4 flower heads in the hopes of making more cobweb thistles
for next year.
Yellow Starthistle- (Centaura solstitialis)
Yellow Starthistle dominated 14 million
acres of California in 1998. In Monterey County, Yellow Starthistle is
a serious invader of rangeland and disturbed roadsides. It outcompetes
other plants including range grasses and natives. One Yellow Starthistle
plant can contain over 1000 viable seeds each year. Toxins carried in the
leaves and stems can be fatal to horses.
Shrubs
Shrubs are low growing, under 8 foot,
woody plant usually having several stems. Shrubs are normally the plants
we refer to as 'bushes' or 'bushy' in shape.
Western poison oak - (Toxicodendron
diversilobum)
This native plant can form a bushy shrub
or a climbing vine 1-10 feet tall. Poison oak grows from sea level to 5,000
feet of elevation. Characterized by alternate leaves with three or occasionally
five veined, shiny leaflets, poison oak thrives throughout California.
To help you remember what poison oak looks like remember these two handy
rules. 1) Leaves of three, let it be. 2) If its hairy itās a berry, Shiny
watch your hiney!!! In the autumn, the leaves turn from green to a deep
red color. Exposure to the oily sap contained in all parts of the poison
oak - roots, stem, leaves, flowers, and the fruit (berries) -This oil can
cause skin irritation ranging from mild to severe.
Manzanitas Arctostaphylos
Ericaceae. Heath Family
The manzanita has reddish brown bark that
peels away from its woody trunk and very crooked branches. It is an evergreen
shrub with leathery leaves adapted to conserve water. Small urn-shaped
pink or white flowers become little apples or "manzanitas" which are round
and reddish pink. Native Americans ate them fresh, dried, or to make a
soft drink. They also used the wood of the manzanita for building. A lotion
was made from the dry seeds to soothe poison oak rash. Animals also eat
the seeds and deposit them with fertilizer in new locations to reproduce
new plants.
-
Shaggy Bark Manzanita - This manzanita
gets its name from it very shaggy bark and pubescent hairs on the underside
of its leaves.
-
"Hooker's" Manzanita - This manzanita
has very small leaves that are smooth and waxy on both sides. This species
is considered rare and protected.
-
Sandmat Manzanita - This manzanita
is very low growing with small leaves. It gets its name from the way it
covers the sand dunes like a dense mat.
Ceanothus Ceanothus
Raamnacea. Buckthorn Family
This dense shrub has a variety of species,
both native and cultivated. Ceanothus is a hearty, drought resistant shrub,
that provides a habitat for a host of native insects and animals.
The many Ceanothus species are often refered to as the California Lilacs.
Coyote Bush- Chaparral Broom (Chamiso)
(Baccharis pilularis)
Asteraceae. Sunflower family
These woody, shrubs are adapted to
live through periods of drought thanks to their tough, wind-resistent leathery
leaves which protect them from water loss. They grow abundantly on windy
bluffs in the low ground cover species, while the taller populations out
of the wind, are adapted to the coastal scrub and chaparral. Perhaps they
could be used to make brooms and certainly resemble coyote tails when they
bloom throughout the summer. Parachute seeds then fly in the wind to reproduce
new coyote bush.
Chamise-Adenostoma fasciculata
Rosaceae. Rose Family
This very fragrant shrub is a favorite
of pollinators. The fragrant secretions which offer protection from herbivores
is also increases this plants flammability and provides much of the kindling
for many of the fires in the chaparral environment. Chamise helps start
fires in this ecosystem that burn away old growth and give new seedlings
of all species the opportunity to compete for light and nutrients.
Black Sage- Salvia mellifera
Lamiaceae. Mint family
This large, bushy green leaf shrub grows
3-6 feet high. Heads of blue to lavender or whitish flowers grow on spike
stalks in groups called whorels. While the strong smelling leaves were
used by the early people to clear the nose and flavor food, the strong
aroma also protects the plants from being eaten by deer and other herbivores.
Teas were made of the leaves for upset stomach, sore throat, and stuffy
noses.
Monkey Flower
Sticky, Common, Scarlet
Mimulus auranticus, m. guttatus, M. cardinalis
Scropulariaceae. Figwort Family
Monkey flowers, resembling a monkey's face,
are popular plants among bees, butterflies, hummingbirds (...and children)
who suck the sweet nectar from the orange, yellow, or red flowers. This
helps the flowers to cross-polinate as insects travel from flower to flower.
The leaves become sticky in the hot sun because of a varnish-like substance
that keeps water in and herbivorous predators away. Native Americans used
both the stems and leaves for salad greens. Crushed raw leaves were applied
to open wounds to aid healing.
Lupine
(Lupinus)
Fabaceae. Pea Family
Lupines come in many different species,
ranging in sizes from less than a foot tall to over three feet tall. Some
are annual and reseed every year, while others are perennial growing from
the same plant for many years. They all have palmate leaves which are grouped
in five, like the palm of a hand. Candle-like spikes of flowers bloom in
spring and summer, with each flower resembling the garden sweet pea. Bees
rest on the lower "keel" part of the flower in search of nectar. The bee's
belly is then dusted with pollen from male stamens or cleaned of pollen
by the female stigma, thus pollinating the flower. The root system of lupine
plays host to tiny nodules of bacteria that convert nitrogen from the air
into soil nutrient, helping to improve the soil for all plants.
French Broom
(Genista monspessulana)
Fabaceae. Pea Family
French Broom, although beautiful, is an
extremely aggressive weed. This invasive quickly colonizes disturbed areas.
French broom has a competitive advantage over native vegetation with its
rapid growth, viable seeds, long-lasting seedbank and absence of natural
enemies.
Succulents
Ice plant
(Carpobrotus edulis)
Ice plant, also known as Hottentot fig,
is a well-known invasive weed in Monterey coastal dune areas. This non-native
rapidly attacks and overruns native plants with its creeping radial roots.
Bluff lettuce (Dudleya)
Crassulaceae. Stonecrop Family
This elegant and hearty native succulent,
can be found clinging to the cliffs and bluffs of wind swept sandy regions.
Bluff lettuce gets its name from its lettuce like bunching.
Ivy
Cape Ivy
(Delairia odorata)
Cape Ivy is a familiar groundcover commonly
seen in yards and planting beds. Cape Ivy is a non-native plant that was
introduced by former settlers as a garden plant. Its leaves are dark green
and waxy, typically have 3 to 5 points, and vary in size from 3 to 10 inches.
Small flowers yield small black fruits that birds eat and disperse the
seeds to other areas. Cape Ivy eventually forms thick, fibrous mats on
the ground, choking out all other plants as it creeps ever outward. It
is even able to climb trees and kills them by out-competing the tree for
light and nutrients.
Wild Cucumber
(Echinocystis lobata)
This native creeping vine sprouts every
spring from a very large underground tuber once used by native americans
as food in time of hardship. The vine winds up other plants and produces
small greenish flowers. In late summer spiny, papery seed pods contain
hard seeds which resemble acorns.
