T’S BEEN A
comparatively cool
summer barring a few hot
periods, and fall has finally
arrived – with rain! If you think
about it, in Mediterranean climates
like much of California, fall is really
the equivalent of “spring” in
temperate climates. Fall is the time
when Mediterranean climate plants
awaken from their summer torpor in
anticipation of the winter rainy
season. Like spring planting in
temperate climates, fall in Mediterranean climates is also the best time
to plant many California native plants
and others from Mediterranean
climes such as parts of Australia,
South Africa, Chile and the
Mediterranean area itself.
All but the most tender tropical
plants benefit from being planted in
our mild fall and winter. It’s a chance
for the plant’s roots to develop so
they will be better prepared for the
stresses of a hot, dry summer. This is
doubly important for some natives
that are sensitive to summer irrigation.
These, if planted in fall, can be
watered less through their first few
summers because they are better
established.
Several trees and shrubs in the
Azalea Family benefit from fall
planting and will be available at the
sale. These are the manzanitas and
strawberry trees. All are evergreen
trees or shrubs that have leathery
leaves and attractive, reddish, peeling
bark. The largest is a hybrid derivative
strawberry tree, Arbutus ‘Marina’. This
handsome tree grows slowly to 30 or
Justicia rizzinii, firecracker flower, in bud.
more feet. It has four-to five-inch,
deep green leaves that are bronze
when emerging and clusters of tiny,
urn-shaped flowers that are typical of
the group. The pink flowers are
produced in spring and fall and are
followed by showy fruits. The fruits
start out yellow and turn red, often
with both colors on the tree at the
same time. The origin of A. ‘Marina‘
remains somewhat of a mystery
though it is thought to be derived
from Mediterannean, European, and
possibly, Canary Island natives.
Two manzanitas that can be trained
into small trees (and will be found
with the trees at the sale)are Arctosta-
phylos densiflorus ‘Sentinel’, Vine Hill
manzanita, and Arctostaphylos manzanita
‘Dr. Hurd’. Like Arbutus, they both
produce clusters of tiny urn-shaped
flowers. ‘Sentinel’ flowers are light
pink and ‘Dr. Hurd’ flowers are
white. ‘Sentinel’ is the smaller of the
two at eight to 10 feet compared to
‘Dr. Hurd’ at 15 feet tall. Training
these two manzanitas as trees shows
off the classic red bark. These two
are among the most reliable of
manzanitas for our Inland gardens.
Shrubs in the Azalea Family that
will be available at the sale are a
dwarf form of strawberry tree and
two other manzanita cultivars. The

being appealing to birds. Many other
plants Jean mentions will also be
available at the sale, often in multiple
varieties. Here are some, listed mostly
by genus. A number are discussed in
more detail in this article. Check the
plant list for more information on
others. (See how to get your list on

Buddleia ‘Buzz Violet’ is one of several
new introductions that are among the
smallest of the butterfly bushes,
supposedly growing to only two or
three feet tall. This selection has
fragrant, violet flowers in dense,
conical spikes. Perhaps the most
distinctive is woolly butterfly bush,
Buddleia marrubifolia. This is a Chihuahuan Desert native growing to about
five feet tall. It is a compact plant with
small, white, fuzzy leaves and its rich
yellow-orange flowers are born in
little, ball-like clusters. All but the
woolly butterfly bush benefit from
being cut back after each bloom cycle.
There will be many other plants at
the sale that are attractive to butterflies. Two particularly distinctive
groups are the milkweeds and the wild

known as a larval food source for
Monarch butterflies. Three species will
be offered at the fall sale. Asclepias
curassavica, bloodflower, is native from
Mexico to South America and the
selection, Asclepias curassavica ‘Wildfire’,
sports red-tinged foliage. It has threeto four-foot, few-branched stems lined
with narrow leaves and topped by
clusters of unusual, crown-shaped
flowers typical of milkweeds in vivid
red and orange. This species needs
fairly regular irrigation. There will also
be two California native milkweeds
available. The hard-to-find narrow-leaf
milkweed, Asclepias fascicularis, is an
herbaceous perennial growing from
two to four feet tall. It has slender
stems lined with very narrow leaves, as

State of the Gardens
PLANTS TO SEE: Autumn is the season of mellow fruitfulness and several
interesting plants in the Botanic Gardens are in fruit. The paper mulberry
along the main drive is shedding hundreds of aggregate orange fruits. I do
not recommend you plant this tree in
your garden. It grows large, sprouts
roots, and seeds profusely each year.
Another member of the fig family,
along with the black and red mulberries planted close by, is the Osage orange, whose bright green, aggregate
fruits are lying along the stream bed.
Closer to the entrance plaza are the
pink fading to buff fruits of the goldenrain tree and Chinese raintree, the
fall flowers of which are bright yellow
at this time of the year.
Across the main drive in the California desert section are the pink-yellow
pods of mesquite that were gathered
by Native American desert
tribespeople. Also, brown jojoba nuts
are ripe and shed in fall. The yellow
orchid vine (Mascagnia macroptera)
collected in the Sonoran Desert many
years ago has yellow-green fruits turning to buff and scrambles over the
Dugger Ramada and adjacent fence.
The California Buckeye has large
fruits and conker seeds along the
north coast wheelchair pathway, which
is ablaze with red-orange flowers of
the California fuchsia, a hummingbird
flower (Epilobium or Zauschneria). A
white-flowered Western redbud is
blooming behind the memorial bench
for John R. Grim along the walkway.
A more usual purple-flowered form
will bloom later across the path. The
Rancho Rose Garden always supplies
color in fall, as does the Otay Mesa
rose, providing it receives sufficient
water. Unfortunately its fruits are
green with prickles. There is an Eastern pokeberry fruiting in the old rose
garden and in the Geodesic Dome. I
think the birds spread seeds from
neighboring Oscar Clarke’s garden.
There are many autumn sages blooming along the main drive by the Gardens office, and across the road on
salvia knoll.
Down hill from the autumn sages
are pomegranate trees in fruit. The
color contrast of the foliage of the
blue-green Italian cypress and
‘Swaine’s Golden’ cypress, planted between the rose garden and the greenhouse is very noticeable in fall
sunlight, as are the flowers of Texas
Ranger and its relatives planted at the
edge of the Iris Garden. There are
many interesting colorful plants in
bloom and fruit in the Herb Garden.
h
TREE WORK: Two dead white alders
(Alnus rhombifolia) were removed from
Alder Canyon in late August. These
plants are native along streams in the
local San Gabriel and San Bernardino
Mts. and formed part of the riparian
community originally planted in the
canyon. A Siberian elm tree (Ulmus
pumila) that was heavily infected with a
bacterial disease and regularly
dropped dead branches was also removed from the canyon by Vista
Landscape of Riverside. The same
company trimmed a split branch of a
mesquite tree near the turnaround.
This allows more sunlight to reach the
cactus knoll. Funds for this work were
provided by the Arbor Fund, a donor
advised fund of the Community Foundation Serving Riverside and San
Bernardino Counties.
h
WHEELCHAIR PATHWAYS: Physical
Plant organized removal of a large
Taxodium mucronatum root that had
raised asphalt near the bridge over the
pond and made that walkway dangerous for wheelchairs, schoolchildren
and general visitors. The pond is very
popular with young folks who come
to see the fish and turtles.
Abe Koksal, Jason Timme and student assistants repaired the railroad-tie
retaining wall along the original
wheelchair walkway that climbs the
east side of Alder Canyon. The wall
had collapsed in one place and was
leaning in a second area behind the
Gardens’ garage. Several of the timbers had rotted out on the section of
the walkway below the Rose Gardens.
There is still another part to repair behind the garage where a coral tree was
removed that was lifting the asphalt.
Once all the walls are repaired, the
uneven asphalt surface will be re-
placed. Since this pathway is used by
many school tours, Primavera funds
have been assigned to this project.
h
WILLA SCHWALM BEQUEST: The
UCR Foundation received a bequest
from the estate of Mrs. Willa Schwalm,
wife of Professor Hal. Schwalm, that
was to be added to an endowment in
the Botanic Gardens. Hal Schwalm
was a member of the College of Natural and Agricultural Sciences and was
head of UC Cooperative Extension in
the southern half of the state in the
1970’s. In 1990, Willa donated a teak
bench and a Cyprus cedar (Cedrus brevifolia) tree in Hal’s memory, both of
which are located in the Mediterranean section of the Gardens southeast of the pond.
h
TORO GIVING PROGRAM: In
March, Deb Whitney, Margo Chabot,
Theresa, and I put together a grant request to the Toro Giving Program for
a piece of equipment made by the
Toro Company, who have a plant in
Riverside. In July we heard that we
were successful, but the amount and
which item of garden equipment has
yet to be determined.
h
ROBERT SIMONSEN: I am saddened
to report the death of Bob Simonsen,
who with his wife Nan, helped develop the Garden Tour/Classes. Bob
also volunteered at plant sales checking receipts at the exit gate, and working the membership table. At

out glasses and buffet plates. We all
enjoyed Bob’s company. He will be
greatly missed. Our condolences go

HAT IF SOMEONE were to
offer you an attractive sum of
money to correctly answer this
question: “What is the most popular
hobby in the country?” I predict that
you would lose out on that little
bonanza. You would probably answer
“golfing” or “fishing:” or “gardening”.
But the answer is actually Bird Watching! Yes. Birding is America’s most
popular pastime. My goal in this
article is to explain what birding is,
and why it is so popular.
The practice of birding encompasses
everything from the casual observation of bird life in your yard to a form
of single-minded fanaticism rarely encountered in any other pursuit.
Birding is a recreational activity, as
opposed to bird hunting. It first became popular during the Victorian
era. Because binoculars and telescopes
were rare, birding mainly involved the
collecting of bird eggs, and sometimes
bird skins. (The collecting mentality
still does underlie much of the allure
of birding.) Some people opine that
these activities were not true birding,
and should be labeled “proto-birding”.
Toward the end of the nineteenth
century, the predatory activities of
birders along with the destructive
trade in feathers (particularly in the
millinery industry) led to a public call
for bird protection. In 1905, the
National Audubon Society
was formed to protect birds
and promote non-destructive forms of bird observation. Early in the 20th
century the use of primitive optics like
opera glasses and the first handbooks
for field identification made it possible
to “collect” birds without shooting
them or stealing their eggs. Many
agree that “true” birding began in
1934 with the first pocket sized field
guide to birds by Roger Tory Peterson.
With the availability of quality, affordable binoculars and of field identification guides, it is tempting to gloss
over the actual process of bird identification and wax lyrical about the fabulous adventures ahead for birders.
However, even with good binoculars
and a good “bird book”, learning to
match the illustrations with what you
see flitting among the leaves or hopping around in the shadows is actually
pretty tricky. For one thing, as with
any other type of animal, not all birds
of a species look alike. Aside from the
obvious dimorphism between the
sexes in most birds, there are also geographical variations in plumage, seasonal differences, and life stage
variations. Further, no one guide can
be entirely comprehensive.
For beginning birders, the the most
obvious bird to spot is an adult male

in breeding plumage. They are
usually the most distinctive
and colorful, likely to be
perched conspicuously and
singing to advertise their territory. A good look at a breeding male may allow the
beginner to find the match in
the book. However, getting a
good look can be frustrating.
Making the jump from seeing a bird
with one’s eyes to spotting it with
binoculars takes practice. And, at the
risk of belaboring the difficulties,
breeding season coincides with the
“leafiest” time of year. Birds can be
very frustrating in their unwillingness
to get into a clear spot.
My advice for the beginner is to
keep at it. You will break through the
beginner problems, and it is so worth
it. Also remember that where there
are breeding males, there are females.
Soon there will be fledglings. This
means that if you know the species of
males you saw, you are already ahead
in identifying the females, and, with
time, the young.
There are two more categories of
clues for identifying birds. The first,
and easiest, is to use the range maps
included in most books. Two similar
looking birds will often be geographically separate. For example, if you are
birding in Riverside, any bird whose
range does not include the West can
almost always be eliminated. (We’ll
leave the issue of “accidentals” alone.)
Likewise, the habitat, elevation, and
typical activities described in bird
9
UCRBG Newsletter • Vol. 30 No. 3 • Fall 2010
books can be matched with what you
are seeing.
The second category is songs and
calls. One can identify a bird without
seeing it at all. Many times a song will
clearly distinguish between birds that
are difficult to distinguish visually.
Here, you can make use of the internet
or the library. Both places keep
recordings of bird song. Although I
have been an enthusiastic birder for
decades, I am still poor at identifying
songs. It is a skill very worth learning.
With all the difficulties, why bother
to go through the effort of learning to
identify birds? Because this gives you
the tools you need to start “The List”.
Birding is all about The List. I think it
is human nature to record what you
have made an effort to identify even if
it is simply birds coming to a feeder
outside your kitchen window. You
write down the birds you see on a
given day and number them. That is
the beginning of your “yard list”. You
will be motivated to add to it over time.
Soon you notice that in spring and
fall, you see different species than
usual. How about that? Migrating
birds are passing through your yard!
Because you want to increase your
“yard list”, you add different types of
seeds and suet to your feeder, and notice that different birds take advantage of them. Before long, you decide
to track the number of birds you see
through the course of a year. Your
“year list” begins.
The obvious extension of this is The
Life List. Almost every birder accumulates a list of all the bird species they
have ever seen. And because you are
human, you will want to make all your
lists as long and impressive as possible.
You will take the opportunity to look
for birds in other places around town
outside your own yard. In Riverside,
we are lucky to have the UCR Botanic
Gardens, forty acres developed and
managed to provide great bird habitat
throughout the year. We also have
Sycamore Canyon Park, the Santa Ana
River bottom, and many others.
In most areas, including Riverside,
bird “hot lines” exist. These are info
centers where the details of unusual
bird sightings are made available. Now
every time you leave town, you pack
your binoculars and book while in-
cluding in your itinerary the likely hot mala and then into Honduras.

Attracting Backyard Birds
JEAN T. WEISS
I
HAVE NOISY neighbors, but
these jays, wrens and mockingbirds are music to my ears. By
providing water, cover, food and places
to raise young, I have counted 71 species
of birds in my yard. How can you provide these necessary resources in your
yard? Here are some tips that you can
put into action. Then just start counting!
WATER: In this climate, water is the
most critical resource. Water splashing,
bubbling or spraying is a beckoning call
to birds. In summer the native plant
communities surrounding Riverside remind us that we live at the edge of a
desert. Even with winter rain, birds
need water.
Fountains should have a shallow area
for birds to bathe. Deep bird baths with
a few flat rocks can create different
depths. Dishes of water on the ground
will appeal to California Quail, Mourning Doves, and California and Spotted
Towhees as they scratch for seeds and
bugs in the leaf litter. Flower pot saucers are a simple solution. Birds have
mastered the various irrigation systems.
Ground dwellers as well as Northern
Mockingbirds and Scrub Jays listen for
the trickle of drip emitters. Goldfinches
are adept at finding residual water in
sprinklers while a hand-held
hose will attract hummingbirds
for a quick shower. Be sure
some water features are near
trees and shrubs, providing
shelter for the birds. Ideally
cats should be kept indoors.
COVER: Have you ever noticed a noisy wren scrambling
around in low dense bushes?
Or a Scrub Jay gliding from
tree to tree? On summer nights you can
hear Barn Owls circling their nests high
in the palms. Birds have adapted to vegetation of different heights. By grouping
short, medium and tall plants you are
creating habitat niches that attract more
species. Dense clusters are always more
protective than individual plants or
those in a straight line. Seasonal changes
are also a consideration. The golden fall
leaves help camouflage yellow warblers
during migration while evergreens provide shelter for the winter residents
during the cold, rainy months.
PLACES TO RAISE
YOUNG: Some nests require a thousand or more
pieces of nesting material.
By piling dead twigs and
grasses such as deer grass
in a conspicuous area, you
are concentrating the supply for efficient nest building for Scrub
Jays, Northern Mockingbirds, House
and Bewick Wrens and House Finches.
Energy previously lost from scavenging
can now be directed toward raising a
successful clutch. Black Phoebes and
American Robins require mud for their
nests. This can be found in heavily watered lawns such as Alder Canyon
where generations of Black Phoebes
have built nests under the eaves of the
Conference Room. In a xeriscape, a sufficient amount of wet, clay soil can be
provided in a secluded spot by sinking a
garbage can lid into the ground.
Maintaining neat, manicured gardens
not only reduces nesting material, it also
eliminates sites for cavity nesters. American Kestrels, Western Bluebirds, Acorn
and Nuttall’s Woodpeckers, Screech
Owls and Flickers use holes in old, decaying trees. These are frequently
removed to “clean up” the yard. In this
case, birds would benefit
from bird houses with dimensions and placement for their
particular species. Simple
houses of redwood, white
cedar and cypress in natural
dull colors are the best. They
can be mounted on a post or
screwed to a tree. Face the
entrance away from the winds
with a slightly downward tilt
to prevent rain water from collecting.
By setting up the bird house in late
summer or early fall, it can weather
over winter and be more appealing to
nesting pairs the coming spring. No
matter where the birds build, their
safety and proximity to food determines
their breeding success.
FOOD: Although many people use bird
feeders, it is much easier to landscape
with plants that offer a steady diet of
nectar, seeds, fruits and berries. California natives such as ceanothus, encelia
and manzanita will attract insects and
provide nectar and seeds for
birds that have evolved with
that plant community for hundreds of years. However, many
Mediterranean-climate exotics
can be counted as avian favorites and offer splashes of
color, especially during the
summer. They, too, take minimal care.
Encourage insects by eliminating pesticides, allowing leaf litter to accumulate
and leaving dead branches when possible. It is rewarding to see birds discover
their favorite food!
LIKELY BIRDS IN YOUR YARD:
Hummingbirds. The two most common residents are the Anna’s and
Costa’s. They eat insects, spiders and
nectar, favoring red tubular flowers.
Good fall choices are pineapple sage,
autumn sage and California fuchsia. For
spring consider coral bells, columbine,
ocotillo, agave, and aloe. In summer
there is lantana, buddleia, trumpet vine,
etc. Fill feeders with sugar water (1
part white sugar, 4 parts water) without
red food coloring.
Lesser and American Goldfinch. In
the wild these perky yellow and black
finches live in weedy fields and meadows often with thistle which provides
seed to eat and down for their nests. In
the garden, large flocks descend on
sunflowers, dandelions, evening primrose (Oenothera hookeri), sages and rosemary. Last winter I counted 52 of them
jockeying for position at my niger (thistle) tube. Goldfinches complement
their diet with 50 percent insects when
raising young.
Black Phoebe. Nicknamed the
“Tuxedo Bird”, this black and white flycatcher is common around garden
pools or lawns with lush vegetation. It
darts out from a perch catching insects
on the fly, then returns to wait for the
next snack.
Woodpeckers. Nuttall’s and Acorn
Woodpeckers are permanent residents
that drill out wood-boring insects from
dead trees and branches with sharp,
pointed bills. Colonies of Acorn Woodpeckers are common in oaks, the source
of their acorn stash for the winter.
Common Bushtit. These birds nest
here year round, but it is the large
11
UCRBG Newsletter • Vol. 30 No. 3 • Fall 2010
flocks in winter that attract the most attention. These acrobatic little gray birds
make a “tit tit” sound to stay with the
group as they travel across your yard.
House Finch. The red crown, breast
and rump of the male is so attractive that
this western native was introduced Back
East as a cage bird in the 1940s. It has
adapted well to residential areas where
it eats seeds and soft fruit such as figs.
Mourning Dove. Doves often join
House Finches and House Sparrows in the
driveway to feast on wild bird seed mixtures. Being ground feeders, they forage in
herbaceous borders, flower beds and
under shrubs for small berries and seeds.
California poppy seeds are a favorite.
Scrub Jay. This raucous being is a
conspicuous visitor. One year my resident family called out for raw peanuts
every time I appeared in the yard. The
jay prefers dense foliage where it eats
T
acorns, garden fruit and berries from
the elderberry, manzanita, and Oregon grape. During nesting season it
favors insects, small reptiles, rodents,
and even the eggs of song birds.
Hooded Oriole. These summer residents nest primarily in palm trees.
They eat insects and caterpillars and
probe flowers of agaves, aloes, coral
trees, bottlebrushes and Cape honeysuckle for nectar. They also like blackberries, elderberries and many kinds
of fruit such as prickly pear. Orioles
are so attracted to hummingbird feeders that oriole feeders with orange accents have been designed for them.
Northern Mockingbird. These entertaining birds have an extensive
repertoire of songs and imitate everything from other birds to train whistles. An ideal habitat would include a
grassy area to forage for insects such
as grasshoppers and beetles as well as
berry bushes of pyracantha, Oregon
grape, toyon or Nevin’s barberry. Soft
fruit is appealing, too.
Many of the plants mentioned above
(and more!) will be offered at the
UCRBG fall plant sale the weekend of
October 23-24. The informative signage, Master Gardeners and Gardens
staff will help you select those that
will best accommodate your avian visitors and enhance your landscape. This

Fall Events - Comings & Goings
HERE’S A LOT happening in the
Gardens this fall. We begin with
recent events and remind you of
those that are yet to come.
Bird Walk & Breakfast: Early Saturday, October 2, nearly 30 enthusiastic
birders gathered in front of the Conference Room. As we
gathered, someone
sighted a bird. (See
our response in the
photo.) Under the
leadership of Janet
Clegg and Norm
Ellstrand, we sighted a number of the
usual suspects mentioned in Jean’s article. The bird walk is a good time out in
nature. It is planned again twice next
spring.
Adult Education Garden
Tour/Classes: Later that same Saturday,
garden lovers joined Amy Hao for a tour
of the Vivian Estate. The lovely, ornate
grounds combine Italianate elements
with Victorian romanticism for a lasting
impression. Expansive courtyards lead
into secluded niches, paths wander
among statuary and various water features, a meditation garden offers an
intricate stone labyrinth.
In September, Amy hosted the Tour/
Class at her charming 1909 craftsman
home with its lush plantings. Van Brandon of Parkview Nursery (on Chicago)
talked about taking plants and gardens
into fall and winter.
The Annual Fall Dinner: That Sunday, nearly 70 Friends and their guests
enjoyed a perfect evening in the Gardens. A delicious dinner followed wine
and appetizers amidst the sounds of
laughter and conversation. Presenter
Kathleen Socolofsky,
director of the UC
Davis Arboretum,
explained her 10
year plan which interfaces the Arboretum with the city of
Davis and the university while using
community service as an underlayment. Two years out from the conclusion, she shared that they are on target
to meet their goals. And, yes, this year
the weather during the presentation
bordered on balmy!
