Review: sex and the single flower
 Pollination is the act of transferring pollen grains from the
male anther of a flower to the female stigma. It’s necessary
for seed and fruit production in most higher plants.
© Project SOUND
Sometimes physical
agents transfer the
pollen
http://www.annerondepierre.com/wisdomarchive8.htm
Only about 20% of plants are wind pollinated
And <1% are water pollinated

Living creatures (pollinators) usually carry the pollen
from flower to flower
Colony Collapse Disorder – our wake-up call

Why worry about living pollinators?
 They play a key role in the normal
functioning of our local ecosystems
 > 200,000 plant species worldwide
depend on pollination
 Imagine life without these plants
 They are required for production
of many of our food, medicinal and
other crops
 ~80% of the world’s crop plants
depend on pollination – 150 crops in
the U.S. alone
 A combined annual $20+ billion
industry in the U.S
 Without them, our gardens would
not sustain themselves; many
flowering plants would eventually
become extinct.
© Project SOUND
 Many pollinators at risk:
 Non-native pollinators are
vulnerable to environmental
factors - limited genetic
variability [Example: Honeybee
Colony Collapse Disorder]
 Native pollinators are at risk
due to habitat loss, climate
change and use of pesticides
 Crop production world-wide is
decreasing due to decreasing
numbers of pollinators
 So we all should be worried
 The time to take action is NOW,
in our schools, home gardens,
places of work and anywhere
else that we can promote the
well-being of pollinators

National Pollinator Week
 U.S. Senate designated the 3rd week in June as “National
Pollinator Week” . The U.S. Secretary of Agriculture signs the
proclamation every year.
 Now an international celebration of the valuable ecosystem
services provided by bees, birds, butterflies, bats and beetles.
 “Pollinating animals are vital to our delicate ecosystem,
supporting terrestrial wildlife, providing healthy watershed,
and more.
 Pollinator Week is a week to get the importance of pollinators’
message out to as many people as possible. “
© Project SOUND
Even before colony collapse disorder,
some people were concerned…
 Depending on a single source
– for anything – should make
us nervous
 Better to ‘diversify the
portfolio’

European Honey Bee
Apis mellifera
Why worry about other pollinators? Can’t
the bees do the pollination work?
 Flies and bees are the two most
important insect pollinator groups.
 Depending on the region, the time of
the day, the flowering phenology and
weather conditions, flies may be
the main or exclusive pollinators,
or share pollination services with
bees and other pollinator groups.
 Native pollinators play an important
role – not just in the wild, but in
gardens and agricultural fields
© Project SOUND
It turns out that pollination is
a lot more complex than
early agricultural studies led
us to believe
© Project SOUND
Who are the living (biotic) pollinators?
 Bees – of all sizes
 Butterflies
 Moths
 Flies & other fly-like insects
 Beetles
 Hummingbirds
 Ants
 Bats
 Even small reptiles & mammals
Most common
Least common

Mother Nature plays it safe with regards to
pollination
 Most insect pollinated flowers receive visits
from several different types of insects:
bees, flies, beetles, bugs, etc.
 In a study of 2200 CA plant species:
 71% of the out-crossing species were visited
by two potential pollinators
 49% were visited by three or more potential
pollinators
 Redundancy in pollination systems is
probably the rule, rather than the
exception.
© Project SOUND
By hedging her odds
We too should hedge our bets and support
many different types of pollinators…
© Project SOUND
…but how, particularly given our small urban gardens?

Planning for pollinators: knowledge and
making good choices
© Project SOUND © Project SOUND
Knowledge is power: what we each can do to
promote our native pollinators
 Plant the plants they need
for food – at all stages of
their lives.
 Provide places where they
can reproduce and provide
for their young
 Protect them by practicing
Integrated Pest Management
– limited/no use of
pesticides
 Teach others – by word and
example – about the value of
native pollinators

Many butterfly larva require specific food
sources – more on that next month
© Project SOUND
Fortunately, many generalist pollinators
are less picky than we once thought
© Project SOUND
http://mommyculture.com/?p=678
There are just five basic principles for planting to
support a wide range of pollinators
What makes a good pollinator landscape?
5 elements according to the latest evidence
 S (size) - The larger the area covered
by flowers/plants the better
 A (abundance) - The greater the
number of flowers the better
 L (length) - It’s important that
something is flowering from early
spring through fall
 U (useful attributes) –The plants must
provide quality pollen and/or nectar
 D (diversity) - Diversity of plants to
attract both generalists and specialists
© Project SOUND
SALUD! – To your health!
http://picturesforcoloring.com/2012/05/bee-coloring-pages-for-honey-lovers/
Using these elements in our gardens…
© Project SOUND
Really not so difficult
once we understand
the principles http://non-secateur.blogspot.com/2011/05/southern-californias-best-garden-blog.html

Why are some plants pollinator magnets? Characteristics of ‘pollinator magnet’ plants
 Lots of little flowers
 Flowers have simple, open
architecture – ‘accessible to all’
 Flower color often white, pink
or yellow
 Often – but not always – long
bloom season (or several)
 May be sweetly scented (but not
necessarily noticeable to us)
© Project SOUND
Lots of little flowers: many popular choices
 Apiaceae (Carrot family)
 Asteraceae – (Sunflower family)
 Baccharis
 Grindelia
 Hydrophyllaceae (Waterleaf family)
 Phacelia
 Lamiaceae (Mint family)
 Salvia (Sage) and others
 Polygonaceae (Backwheat family)
 Eriogonum – Buckwheats
 Rhamnaceae (Buckthorn family)
 Ceanothus, Rhamnus
 Rosaceae (Rose family)

California Buckwheat - Eriogonum fasciculatum
© Project SOUND
California Buckwheat: sprawling sub-shrub
 Size:
 2-5 ft tall
 3-5 ft wide
 Growth form:
 Low mounded sub-shrub
 Semi-evergreen shrub
 Many-branched
 Foliage:
 Leave alternate, but densely
clustered at nodes
 Evergreen, narrow lanceolate
(sometimes nearly needle-like)
 Roots:
 Net-like; hold soils well
http://www.newportbay.org/plants/index.html
© Project SOUND
CA Buckwheat cultivars make good, life-
friendly groundcovers
 ‘Dana Point’ - brighter green leaf,
more mounding than species
 'Bruce Dickinson' – good for
groundcover; stays close to the
ground, spreads nicely, and holds
good form throughout the year.
 ‘Theodore Payne' – low groundcover
(1 ft high; 1-3 ft spread)
 'Warriner Lytle' - A sprawling low
growing California buckwheat; can
grow to 2 feet tall but is often more
prostrate, hugging the ground like a
mat
‘Dana Point’
‘Warriner Lytle’ © Project SOUND
CA Buckwheat: showy for months
 Great for summer color: May-
Nov. possible
 As an alternative to the non-
native Rosemary; far better
pollinator habitat plant
 In perennial beds
 On parking strips & bordering
paths and driveways
 For erosion control
 Larval foodsource for Morman

Native plants: what’s their secret?
Native plants attract pollinators by
providing quality nectar and/or pollen
What about non-native species? Herbs are
often your best bet  Mint family
 Basil
 Bee Balm (Monarda)
 Catnip
 Lavender
 Mints
 Monarda/Monardella
 Rosemary
 Sage
 Thyme
 Apiaceae (Carrot family)
 Parsley
 Dill
 Borage
 Chives

http://jimlongsgarden.blogspot.com/2010/05/bees-arrive-at-long-creek-herb-farm.html
Many can be combined with natives;
most attractive to bees
Non-native flowering plants for pollinators
– you may have to search to find them!
 Non-native flowers: look for
 Old-fashioned – open-pollinated
/ ‘heirloom’ varieties
 Search on ‘butterflies’ for
plants that may have broader
appeal to pollinators
 When buying bedding plants,
look for plants with pollinator
insects flying around them at
the nursery
© Project SOUND
Some ‘modern’ flowering
plants are specifically bred to
NOT be attractive to bees
and other pollinators

Buckwheats, Salivas (Sages) and other local sub-
shrubs are great pollinator plants…
But they do need sun and space
Achieving adequate floral coverage in each
season: it takes some thought if space is limited
 Flower patches: at least 3 ft x 3 ft
per species – the bigger the better
 A few well-chosen plant species
might be better than many
 Most bang for buck: shrubs vs. annual
wildflowers (depends on situation)
 Likely will need to use vertical space
 Some shrubs and trees are quite
adaptable to small/narrow spaces
 Lots of ‘flowering area’ with a small
footprint
 One yard can’t do it all - “it takes a
neighborhood”
© Project SOUND
http://www.northwestbotanicals.com/portfolio_chcraftsman.htm
You can make any yard more pollinator
friendly – no matter how small or shady
© Project SOUNDhttp://www.northwestbotanicals.com/portfolio_chcraftsman.htm
http://bammorgan.blogspot.com/2008/04/payne-foundation-garden-tour.html
You just have to garden ‘smart’
How can I possibly supply lots of little
flowers year-round?
 Think outside the (horizontal)
box – use your vertical space
 Shade trees
 Vines & climbers
 Espalier
 All other things being equal,
choose the plant with greater
pollinator habitat value

Toyon/California Christmas Berry –
Heteromeles arbutifolia
 Member of the Rose Family
(Rosaceae)
 Occurs from SW Oregon to
Baja CA
 Occurs in several plant
communities
 Chaparral – throughout CA
 Coastal Sage Scrub
 Oak woodlands
 Coastal prairie
 Var. macrocarpa found only on
Catalina and San Clemente
Islands

Toyon is a joy of color year-round
 Evergreen large shrub/
small tree w/ stiff foliage
 Usually 6-10 ft tall, can be
20-30 ft. in right location
 4-10 ft wide (to 25 ft)
 Spring – new growth is
light green
 Plant takes anything from
full sun to very shady
 Quite drought-tolerant
Toyon is a mass of blooms in summer
 Blooms June-July
 Showy flowers in dense
bunches
 Flowers small – look like little
white rose blossoms (Rose
family)
 Bee-pollinated – so good
plant for native bees
 Good nectar plant for
butterflies
 Even quite young plants
(several years old) will bloom)
 Fall/winter – red berries
Traditional uses for
Toyon
 Background/specimen plant
 Large shrub – anywhere that
you would consider Pyracantha
or Holly
 Grows well with Coastal Live
Oak & other dry trees
 Shady parts of the garden
 Slopes – good for erosion
control
 In a habitat garden featuring
local native species
But what if we don’t have room for a
large, free-standing shrub?
 Toyon is very adaptable
 Prune up: makes a very
acceptable (and life-
friendly) shade tree
 Use in a hedge or
hedgerow; can hedge-prune
or leave more natural
 Bonsai in a pot
 Even espalier it along a wall

If you were a pollinator (other than a hummingbird) which
would you visit?
When choosing a shade tree or other
large shrub, maximize habitat value
 Nesting places/cover
 Perching/sunning places
 Flowers for nectar/
pollen
 Fruits
 Foliage useful as larval
food source
© Project SOUND
The majority of our pollinators flew from April to Oct. last year.
We’ll want to supply food throughout this period.
Mother Nature’s mixed hedgerow (to cover the
short ugly wall)
 Size: 6 ft wide – 30+ ft long
 Large shrubs – all provide good,
multispecies habitat value
 Big-berry Manzanita (winter)
 Lemonadeberry (early spring)
 Chaparral Whitethorn
Ceanothus (spring)
 CA Coffeeberry (later spring)
 Toyon (summer)
 Understory/filler – Yarrow
(summer)
 Pollen/nectar: winter to summer
Toyon espalier: transforming the ugly wall
at Mother Nature’s Backyard
 Young Toyon branches are very
flexible – simplicity itself to
espalier
 Start shaping the first year
 Choose design – ‘informal fan’
 Select branches appropriate for
design
 Remove unwanted branches (those
growing in wrong direction;
crowded branches)
 Tie branches to support lines with
soft ties (cut from old stockings)
 Continue to remove ‘inappropriate’
branches

Fabulous habitat plant
 Good pond-poolside plant – will
need to divide
 Attracts very wide range of
insects (like Mulefat)
 Butterflies – including
American Painted Lady,
Buckeyes and Acmon Blue
 Bees & flies
 Many other weird & wonderful
insects
 Makes an attractive pot plant
 Medicinal:
 Used as a disinfectant for
wounds and sores
 Infusion or dried powered
foliage
http://www.laspilitas.com/nature-of-california/plants/baccharis-douglasii
Limit insecticide use – or use none at all
 Pesticides can kill more than the
target pest – some kill pollinators for
several days after the pesticide is
applied.
 Pesticides can also kill natural
predators, which can lead to even
worse pest problems. Instead:
 Encourage native predators with a
diverse garden habitat
 Expect and accept a little bit of pest
activity
 Try removing individual pests by hand if
possible (wearing garden gloves)
 If you must use a pesticide, choose one
that is the least toxic to non-pest
species

Using fewer pesticides is more
life-friendly for all species

Saltmarsh Fleabane does well in gardens…
 Soils:
 Texture: any local – does very well in
fine-textured soils (clays)
 pH: any local, including alkali, salty
 Light:
 Best in full sun with some water
 Fine with partial shade; not too
particular
 Water:
 Winter: likes it’s water; plant in moist
areas of garden, rainswale, etc.
 Summer: quite flexible; looks better
with some to regular summer water
(Zone 2/3 probably optimal; takes 3)
 Fertilizer: fine with none; organic mulches
work well (leaf mulch)

Versatile in the garden
 Excellent choice for moist
places in garden:
 Stream or pond banks/edges
 Rain gardens/swales
 Areas with sprinkler drift
 Fine with other natives
needing similar water
requirements – remember,
dies back in winter
 Showy choice for fall habitat/
butterfly garden; great with
yellow fall-flowering plants
 Does great in pots; give it an
occasional dose of fertilizer
or top-dress each spring

Lack room and/or water? Try a ‘wetland in
a pot’ for a touch of wetland
 Guilt-free – saves space &
water
 Can contain 1 plant or several –
depending on size of container
 Choose a pretty container;
locate in at least part-sun
 Requires some yearly
maintenance – dividing plants
 See May posting – Mother
Nature’s Backyard blog for
more

A ‘wetland in a pot’ serves several
functions when you include pollinator
plants like Marsh Baccharis

Providing homes for native pollinators
 Native bees don’t build the wax or
paper structures we associate with
honey bees or wasps, but they do need
places to nest, which vary depending
on the species.
 Wood-nesting bees are solitary, often
making individual nests in beetle tunnels in
standing dead trees.
 Ground-nesting bees include solitary
species that construct nest tunnels under
the ground.
 Cavity-nesting social species—bumble
bees—make use of small spaces, such as
abandoned rodent burrows, wherever they
can find them.

can construct or
promote native
pollinator homes in
your garden

Moths are important pollinators in western U.S.
 More prevalent in the Southwest than in other
regions due to warm evenings, hot daytimes,
favorable climate
 Moths visit flowers in search of nutritious
rewards, usually nectar, and transfer pollen as a
consequence of their contact with floral
structures.
 Some night-blooming plant species, especially in
desert grasslands and dune areas, appear to be
specialized for moth pollination
 However, most moth-pollinated plants employ
alternative reproductive strategies. These include
self-pollination, recruiting other (diurnal, or day-
active) pollinators, or simply waiting for the next
flowering season.
 Moth pollination is a risky proposition, and moth-
flower mutualisms are not very exclusive.

Characteristics of flowers that attract large
dusk-to-dawn flying moths
 Night-blooming
 Large size – often > 1 inch
 Light color – often white,
but may be light yellow or
pink
 Tubular shape – those that
attract the large moths
 Sweetly scented – may be
overpoweringly so

Native primroses
in the garden
 Best planted with native
grasses, perennials, annual
wildflowers
 Excellent choice for
water-wise parking strip
 Lovely in pots on a sunny
deck
 Tucked in around other
plants – a ‘filler plant’
 Attract a wild assortment
of insects

Make your garden water-wise and Life-friendly
 Plant the right plants to
attract and nourish native
pollinators
 Provide places for pollinators
to hide and raise their young
 Provide a source of water –
can be as simple as patch of
moist earth or a saucer with
stones
 Use pesticides sparingly
 Respect the pollinators and
the services they provide

‘The growing concern for pollinators is a sign
of progress, but it is vital that we continue to
maximize our collective effort.’
 Do something to make your
garden more pollinator-friendly
 Celebrate National Pollinator
Week – check for local events
(Gardena Willows)
 Learn more about a pollinator
that interests you
 Take photos of pollinators in
your garden – they’re fascinating!
