Habitat Gardening: Dreams and Realistic Expectations









Habitat gardens provide for butterflies and other creatures




Habitat
gardening is becoming popular in the United States and elsewhere.  There’s something satisfying about planting a
garden that attracts a wide range of birds and other creatures.  Many gardeners dream of a garden filled with
butterflies and birds.  But how realistic
is that dream?  And how long will it take
for a new garden to meet those expectations?






One
thing gardening teaches us is patience. 
The best garden features – shade trees, large flowering shrubs, nesting
birds – take time.  But you’ll probably
see some changes right away, when you begin to garden for habitat.  For example, a water source and fast-growing flowering
plants begin attracting insects and birds the first year. 






Native
plant gardens change dramatically in the first decade. Here’s what you’ll
likely experience, when you convert your S. California garden from conventional
garden plants to California native habitat species:








The first year: plants are low and small




Year 1







  • Birds and insects will start coming to a water
    source almost right away.  Water is
    scarce, and creatures are skilled at finding it.  Install several water sources to supply
    this critical resource.



  • Any native that flowers will start attracting some
    pollinators.  There may not be very
    many pollinators the first year, but annual wildflowers, perennials and
    flowering shrubs will see some activity the first year.



  • Any plant that produces seeds will attract some
    seed-eating birds (like gold finches and white-crowned sparrows) particularly
    in late summer and fall.  The more
    annual wildflowers, the more seed eaters you’ll see the first year.












Years 2 and 3: sub-shrubs are larger; annuals still play key role.




Year 2 & 3







  • Flowering perennials, shrubs and sub-shrubs become
    larger, producing more blooms.  These
    attract noticeably more insect pollinators and hummingbirds.  We suggest planting annual wildflowers,
    in open spaces around shrubs, to create still more spring-summer
    pollinator food. If desired, begin to photograph and document the insect
    and bird species visiting your garden.



  • As shrubs and trees grow, more use of them as
    perches and cover by birds and small creatures (lizards).  So you’ll see more of the common birds.



  • More summer-fall, seed-eating migratory birds will pass
    through, as food sources increase.  They
    will likely come as small flocks, and won’t stay long.



  • Omnivorous and insect-eating birds occasionally
    visit; same with dragonflies
















Years 4 and 5: even larger shrubs are maturing.




Year 4 & 5







  • As perennials and shrubs mature, noticeably greater
    numbers and more species of insect pollinators.  May start seeing some rarer native bees,
    flower flies.  Photograph and
    document these – you may be surprised!



  • Insects, including butterflies and other
    pollinators, begin reproducing in the garden, if larval food sources are available.



  • More pollinator moth species (if dusk- and night-bloom plants present)



  • Dragonflies and damselflies start to reproduce in
    earnest in dragonfly ponds.  You’ll
    see more adults even without a pond, due to increased insects.



  • Increased numbers of insect-eating insects
    (Robberflies; predatory wasps).



  • Insect-eating birds increase noticeably.  Watch for Phoebes, Kingbirds, Swifts,
    Swallows, Flycatchers, Mockingbirds, Bushtits.



  • Established plants provide wild greens and leaves
    for tea or medicinal use (depending on what species you’ve planted).



  • If you have
    hummingbird plants
    ,
    regular visits from Anna’s & Allen’s hummingbirds. 



  • Hummingbirds may begin to nest in larger, dense
    shrubs & small trees



  • If trees are large and dense, some common birds
    begin to nest: Northern Mockingbird, House sparrows, House finch.



  • Regular visits from seed-eating finches, other
    migratory seed-eating birds. White-crowned sparrows and Lesser goldfinch
    may become regulars.



  • As leaf mulch and seeds build up, visits from ground
    feeding birds: California towhee, White-crowned sparrow, Doves.



  • Occasional visits from hawks, seeking prey



  • Increased numbers of lizards due to increased
    insects, cover (unless there are cats, which preclude lizards)



  • As fruiting shrubs and trees begin to produce, begin
    to see fruit-eating birds: Northern Mockingbirds, Orioles, song birds in
    winter





 






 


Years 6 through 10: As garden matures, more creatures nest in the garden.







Year 6-10







  • Greater diversity of insect pollinators as flowering
    plants mature.  Most gardens at this
    stage supply food for literally thousands of individual pollinators.
    Consider adding plants that attract specialist pollinators: mallows,
    Annual sunflower, Malacothrix
    species, Oenothera species.   



  • Greater number of bird species, including those that
    specialize in insects or fruits. 
    You may even see flocks of Cedar waxwings, Bushtits, songbirds in
    fall or winter.



  • Plenty of edible fruits for your family as well (if
    you’ve planted currants & gooseberries, elderberries, strawberries,
    wild rose).



  • More birds nest in large shrubs, woody vines and
    trees; greater diversity of nesting birds, including Bushtits, Northern
    mockingbirds, Orioles and others (depending on the trees).



  • Consider adding seating in areas with good views of
    birds, butterflies.  You can do some
    serious nature observation from this point forward.



  • Regular visits from dragonflies and swallows,
    phoebes, flycatchers.  The increased
    numbers of insects are a magnet.



  • Regular nesting of hummingbirds.  Visits from migratory Rufus hummingbird
    are possible (they are the really feisty, copper-bronze colored guys).



  • More insects, including butterflies and native bees,
    complete life cycle in the garden (depending
    on availability of larval food and nest sites
    ).  Consider providing nest sites for
    ground- and wood-nesting bee species.
















Mature garden is a functioning ecosystem.




Year 11 and beyond







  • The garden should be a functioning ecosystem, both
    above- and below-ground.



  • Many species of pollinators visit and complete their
    lives in the garden.  Add seasonal
    flowering plants – or those that attract specialist pollinators – as
    needed.   Don’t forget the shady areas of the
    garden.  Some of the shade-loving
    perennials are great habitat plants.



  • Replace dead plants with new ones that flower and
    produce fruits or seeds. Choose species you like, including some unusual
    ones.  Expect some turnover in
    garden plants – that’s natural. 
    Fill in open spaces with annual wildflowers until new plants get
    bigger.



  • There should be birds in the garden most of the
    time. Birds can be observed conducting all of their usual activities.  The water sources are great places to
    bird-watch, utilized by both the ‘regulars’ and exotic migrants.



  • Natural leaf mulch/duff supports wide range of
    creatures, from insects to salamanders, lizards and others.  Take an opportunity to observe this
    interesting community occasionally. 
    The duff teams with life!



  • Congratulations!  
    You continue to create wonderful habitat for creatures who need it.
     As green space shrinks – and
    climate changes stresses wild areas – garden habitat becomes ever more
    important.  Keep up the good work!

Plant of the Month (August) : Dunn’s lobelia – Lobelia dunnii






Dunn's lobelia (Lobelia dunnii var. serrata) - Mother Nature's Backyard 






By
August, the only perennials blooming in Mother Nature’s Backyard (other than
the buckwheats) are those in moist, shady places.  One pretty little perennial, blooming for the
first time this year, is the Dunn’s lobelia.   The scientific name is pronounced low-BEE-lee-uh  DUN-ee-eye 
sir-RAY-tuh.






Dunn’s
lobelia (sometimes also called Blue lobelia and Rothrock’s lobelia) is a
California member of the Campanulaceae
, the
Bellflower family.  This family has 80+
genera and about 2400 species worldwide, mostly in the Northern Hemisphere [1].  Included are garden favorites like the Campanulas
and the Lobelias.  As suggested by the
common name, the flowers of the
Campanulaceae are
bell-shaped and often blue or violet colored.






The genus Lobelia
is well-known to gardeners. Ornamental cultivars spread their old-fashioned
charm under trees and along shady pathways.
They take a little extra water, and so are useful for naturally moist
areas.  While some are annuals (or
treated that way), perennial species have the added advantage of coming back,
year after year, in a welcome splash of green and blue.  No wonder gardeners like the Lobelias.






Only two Lobelia species are California natives.  Both Lobelia
cardinalis
and Lobelia dunnii are
native to the mountains of Central (Santa Barbara and Ventura Counties) and Southern
California. They also grow along the Monterrey County coast.  Where ever they are found, they favor shady,
moist areas: canyons, seeps, rocky stream banks, the edges of waterfalls – you get
the picture.
 












There is current debate about the proper taxonomic
status of Lobelia dunnii.  Some have proposed reverting to an older
taxon,
Palmerella debilis, first proposed by the eminent 19th
century taxonomist Asa Gray [2]. The California Lobelias do have a
distinctive appearance, and may well deserve a genus of their own.  But since most native plant and garden folks
know Dunn’s lobelia as Lobelia dunii, we’ll stick with that name for
now.






Lobelia
dunnii var. serrata,
the variety we’ve got in the garden, can still be found
in the canyons of the San Gabriel and San Bernardino Ranges, as well as on
Santa Catalina Island and in northern Baja California, Mexico.  It was first collected in the 1800’s and grows
in moist places in Coastal Sage Scrub and Chaparral below about 4500 ft. (1400
m.).    If you hike the moist canyons below
San Antonio (Mt. Baldy) and Ontario Peaks in the San Gabriels, you may have
seen it along the streams.










Dunn's lobelia (Lobelia dunnii var. serrata) - in Spring




Like most local perennials, Dunn’s lobelia dies
back to the ground in fall, to emerge again with the winter-spring rains. If
you continue to water it, the plant will remain green into early fall – then let
it dry out and rest.   Most S. California
perennials really do need a period of rest in the fall.








Dunn's lobelia (Lobelia dunnii var. serrate): young leaves




If you don’t know what you’re looking for, you may
miss the emerging stems (see above).  The
emerging leaves look quite different from the leaves of the mature, summer
plant.  If a plant is happy, it will send
up more sprouts each year, and spreading to a 2-3 ft. patch.   Plants also re-seed in local gardens.








Dunn's lobelia (Lobelia dunnii var. serrate) - foliage




Dunn’s lobelia is an herbaceous perennial, growing
at most 12-18 inches (30-45 cm.) tall.   It is sometimes erect, but as likely to be
somewhat sprawling (decumbent) of habit. 
The leaves are a fresh spring green, elongated and becoming slightly smaller
up the stems. The foliage is quite open; not shrubby, but rather a delicate,
lacy groundcover, somewhat mint-like in appearance.   








Dunn's lobelia (Lobelia dunnii var. serrata) - flowering stem




The flowers are cottage garden pretty – small and
pale lavender or blue. The flowers may be up to 1 inch (2.5 cm) long.  They are clustered at the tops of the stalks. As
flowers open over time, the total bloom season may be a month or more.






The petals are fused into a long tube, with 5
lips.  The lower three lips are elongated
and extend down.  The upper two lobes are
curled tightly back – a unique appearance (see below).  The flowers are loved by long-tongued butterflies;
this plant is often planted specifically to attract them.








Dunn's lobelia (Lobelia dunnii var. serrata) - close-up of flowers




Dunn’s lobelia will grow in most local soils
(except salty or alkali), though it prefers a rich loam.  It does fine in our local clays.  We’ve been most successful growing this plant
on the north side of a tall wall.  It
would also do well in dappled sun under trees. 
We’d only try it in fall sun at the edges of a pond.








Dunn's lobelia (Lobelia dunnii var. serrata) - delicate perennial






This is a species that likes moist soils - it can
even take winter flooding.  Regular water
through the bloom season is probably best. 
We give ours (in clay) a deep soaking every 3 weeks in summer, then
taper off in early September.    That’s really about it.






Lobelia dunnii is a perennial to tuck into shady, moist
places.  It does well with native
grasses, sedges, juncus, Solanum, Nicotiana and others that like a little extra
water.  We’d love to try it in a moist
pot on a shady porch. It’s not a garden diva. 
But it’s charming as a violet is – simple, sweet and unassuming.  And then there are the butterflies!






In
summary, Dunn’s lobelia is a wonderful little perennial.  If you have a moist shady spot – or can
create one – this might be a butterfly plant to try.
