The lupines - the genus Lupinus)

Also known as Lupins (Europe) bluebonnets, old maid’s bonnets or wolfbean

Two groups: Old World lupines, (Mediterranean

regions & E. Africa; 12-13 species New World lupines (N. & S. America);

90% of the genus

Place of original origin???

~ 165 species (or possibly more) worldwide

82 species in CA; 14 in western L.A. Co. An additional 6-10 species in nearby

Santa Monica & San Gabriel Mountains

In short, we have a wealth of

native lupines from our area

Lupines: an interesting genus in the Pea Family

Bloom time: February to July, but usually in spring – often depends on timing of rains

Larger-flowered species usually pollinated by large bees; small flowers may be self-fertilizing (Cleistogamy).

Flower color: white to various shades of blue and reddish-purple, and even a few yellow species

Leaves: palmately compound, with 5 to 9+ leaflets. The number of leaflets on an individual plant can vary.

Pea-like pods with hard seeds

Flowers are typical of the Pea family (Fabaceae)

Five petals are highly modified: Large banner petal (often with a white or yellow spot) – attract

pollinators Two small wing petals Two (fused) keel petals – cover the male & female organs

Lupines & pollinators

Plant sex typically must be consummated by a third party (the wind, a hummingbird, or a bumblebee) that transfers pollen from one blossom to another.

To lure pollinators, plants clad themselves in colorful (to the pollinator – UV-colored flowers may appear white to us) flowers with seductive scents.

While the bee is fertilizing the flower, the plant is returning the favor, offering nectar, the insect equivalent of soda pop, and/or life-giving protein in the form of pollen.

Most lupine flowers offer just a bit of nectar, and just for a short time…

Lupines & pollinators

Lupine flowers have characteristics to specifically attract large bees: Purple/blue color ‘guiding signs’ Heavy-duty landing pad

Bumblebee blossoms often have some form of physical barrier that only the bulky insect can surmount.

In Lupines (and other Peas), the nectaries, along with the sexual organs, are enclosed in the fused keel petals.

When a bumblebee lands on the keel, its weight forces the keel petals to pop open, exposing the flower's private parts (and the nectar).

Bumblebees ‘pump out’ the pollen

Page 9: Luscious lupines   2009

© Project SOUND

Lupine flowers are ‘color-coded for

freshness’ The ‘banner spot’ on lupine flowers helps to guide the bumblebee to the proper landing spot; bees can see the contrasting colors

Lupines only make a small amount of nectar for the pollinator. To advertise that the flower is un-pollinated and has nectar, the banner petal or banner spot is bright white or yellow.

After the flower is pollinated, the banner petal turns reddish-purple - a cue to pollinators that no more nectar is being produced by that flower

Bees (and even we) cannot discriminate well between blue-violet and magenta (bees can’t see red)

If you really want a tree lupine, perhaps your should wait….for ‘L. payneii’ Shrub 4-8 ft. high from a trunk-

like base, to 8 inches in diameter

Flowers very fragrant, varying from white through lilac, lavender, purple

Canyons of the Tapo Ranch, Santa Susana, May, 1918, Theodore Payne

‘This plant has been under observation by Mr. Payne for some years. It grows on hillsides of a reddish clay with occasional outcroppings of gravel. Those with long lavender blooms are quite like a Wisteria in appearance and are altogether the most showy of all our southern lupines.’

This plant has been grouped with L. longifolius – but Theodore Payne (and others) suggested this was a separate species

The Theodore Payne Foundation

recently discovered some old seeds

of ‘L. payneii’

Page 15: Luscious lupines   2009

Our local perennial lupines are sub-shrubs

Moderate sized : 2-4 ft tall & wide

Have a woody root/base

Branches are succulent, at least at their outer ends

Local species: L. longifolius L. chamissonis L. albifrons L. excubitus var. halii L. formosus

Silver Bush Lupine – Lupinus albifrons

Our local shrub lupines are very water-wise

Most are adapted for – and do best in – well-drained soils; some even thrive in sand

Most do best – and live longer – if given only modest amounts of summer water (Zone 1-2 or 2)

A very wet winter (or over-watering) can lead to the demise of shrub lupines – in all but the best-drained soils

Most will be somewhat summer dormant

Longleaf Bush Lupine - Lupinus longifolius

Formerly Lupinus chamissonis var. longifolius

Southwestern CA from Santa Barbara to Baja

Coastal sage scrub, chaparral and oak woodland

Formerly frequent in the foothills and on bluffs along the seashore in Los Angeles, Orange & San Diego counties

Longifolius = long-leaved

Garden conditions

Soils: Texture: well-drained is a must (as for

most local bush lupines) pH: any local is fine

Light: full sun (coastal) to part shade

Water: Young plants: weekly (as needed) until

established Winter: moist soils; monitor & supplement in

very dry years Summer:

Quite drought-tolerant; can get by with no water in part-shade

Will take infrequent (1-2 x per month) if soils are well-drained

Fertilizer: None needed & use will likely decrease

lifespan (true for all the bush lupines)

http://www.calflora.net/bloomingplants/bushlupine.html

Lupines don’t like to be moved –

protect their roots

Protect young plants from predation

Dune Lupine – Lupinus chamissonis

http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?3691,4023,4053

http://wiki.zum.de/Adelbert_von_Chamisso

Immediate CA coast from L.A. Co. to Marin Co.

chamissonis: after Adelbert von Chamisso (1781-1838)

Born Louis Charles Adélaïde de Chamissot at the château of Boncourt in Champagne, France

Became a German botanist who botanized with J.F. Eschscholtz in the San Francisco Bay region in 1816 – he named the CA Poppy after Eschscholtz

During his time in California, Chamisso studied a number of native plant and animal species; his inventory is considered a valuable ecological record to this day.

Was also a poet & writer

Dune Lupine

Always found quite near the coast; on dunes, bluffs, ocean strand

Pretty much always on

rather sandy soils Gets some water from

ocean fog Subjected to maritime

conditions: wind, salt-spray

Lupine leaves –

unusual & attractive

Why palmate shape?

?? to funnel water to base of plant?

Why often silvery/velvety?

?? Protection from insects

?? Protection from sunlight

?? To collect moisture

Dune Lupine – flowers

that seem to glow

Blooms: Early spring; usually Feb-Apr

in S. Bay

Depends on winter rains

Flowers: Silvery violet, with a hint of

pink; white/yellow spot

Relatively large for local lupines

Arranged along flowering branches somewhat above foliage – not very long

Vegetative reproduction: ??

Lupines are master catapultists

In general, Mother Nature likes to spread genes around – locate genetically similar offspring away from parent plant

This also keeps the new plants from competing for light, water & nutrients with the parent plant

Lupines literally ‘fling’ their dried seeds away from the parent plant: Drying pods under mechanical

stress When they reach a certain dryness

they fail - dramatically

The large seeds are then further carried by water or by small animals that may cache them

parishii: after brothers Samuel Bonsall Parish (1838-1928) and William Fletcher Parish (1840-1918), both botanical collectors who lived on a ranch in San Bernardino, California

Made extensive exploring trips through the mountains and deserts.

Samuel was the more devoted of the two and corresponded with and was on very familiar terms with many of the leading botanists of his day.

William served in the Civil War as a sergeant and later sergeant-major. He is registered at San Bernardino up to 1890, and at Long Beach in 1892. By 1906 he was living at Redondo, and later in Hermosa Beach."

Managing our local shrubby lupines

Protect young plants from snails & slugs

Keep area around the plants weed-free

Don’t mulch right up to the woody base – prevent root fungal disease

Be very vigilant in removing these caterpillars

Remove old flower heads and woody foliage for neatness & to renew

Cut back to the base in late fall to winter.

The colors of lupine Lupines come in a select

palette: white, pink, red, blues of many hues, yellow, apricot.

Many have bicolored flowers, usually including white or yellow contrasting with another color.

Why/how these colors?

The pigments: Anthocyanins : appear blue/pink;

change from blue to pink w/ increasing pH (alkalinity)

Carotenoids: Appear yellow/orange In Lupines, only seen if

anthocyanins are lacking

How coloration evolved: co-evolution with pollinators Large bees attracted by blue-

purple flowers Hummingbirds attracted by

red/red-violet/ orange

Lupines: important role in ecosystems

The name Lupinus means "wolf," referring to the untrue notion that this plant robs nutrients from the soil.

In fact, Lupine (along with other species in the Pea family) actually adds useable nitrogen to the soil Mutualistic relationship with

nitrogen-fixing bacteria Bacteria for nodules (‘nitrogen

fixing factories’) on roots Nitrogen is converted to a form

useable by plants – ‘nitrogen fixing’

Leave the roots in the soil after harvesting, to achieve full benefits

Truncated Lupine is a small/mid-size lupine

Size:

1-2 ft tall & wide (usually ~ 1 ft)

Growth form: Somewhat conical – kind of like a

pine tree

Foliage: Typical lupine gray-green

Typical lupine leaves – but with trucated leaflets (hence its common name)

Roots: Tap-root; best if seeded in ground

Like all lupines, have symbiotic relationship with nitrogen-fixing bacteria

Tricks to propagating lupines from seed

Generally, fresh seeds need no pretreatment.

Stored seeds may benefit from scarification or hot water treatment but results vary by species and other conditions – if seeds germinate poorly, try the treatments

Scarify using sandpaper for 5 minutes. Heat water (hot tap water) and soak seeds overnight. Seeds that do not imbibe need to be re-scarified and soaked

As a rule, lupines resent handling, but may be started in flats if shifted while still small and transplanted with no delay. Seeds may also be planted in fiber pots and the plants can be set intact into the beds, after first removing the bottom section of the pot

Consider direct seeding – even for local

shrub lupines

In San Francisco, the National Park Service has found that hand broadcasting and raking in Lupinus spp. seeds worked better than planting nursery propagated seedlings—in fact, their transplants had only 10% survival.

To plant in situ, seeds should be broadcast where wanted (bare ground), raked in, and covered lightly with twiggy branches

Because they are vulnerable on bare slopes,

Stinging Lupines need protection from predation

Warfare in the garden: Lupine defenses

Lupines have succulent young leaves. They protect themselves with:

Physical barriers: hairs

Chemical warfare:

‘stinging’ hairs; release chemicals that induce allergic skin rash

Toxic substances in their foliage

Toxic seeds (at least to mammals)

What is lupine

toxicity?

Many lupines (and others in the pea family) produce levels of alkaloids (bitter tasting compounds) that make the seed unpalatable and sometimes toxic.

Eating mature/dried plants & pods can cause several syndromes (the green plants are usually safe): (1) convulsions after exercise due to

alkaloids in the seeds; (2) liver damage caused by fungal toxins

(phomopsins) produced by Phomopsis spp. growing in the seeds, which also causes intermittent photosensitization (called also lupinosis);

(3) possibly precipitation of acute attacks of copper poisoning;

(4) skeletal myopathy; and (5) pregnancy toxemia and acetonemia in

cows.

In animals, toxicity occurs when animals consume large amounts of pods in a brief period

So, never eat lupine seeds;

if kids/animals may be

tempted to eat pods/seeds,

then remove mature pods

Coulter’s Lupine: upright form gives a competitive advantage?

Size: 2-3 ft tall

2-3 ft wide

Growth form: Herbaceous annual wildflower

Upright growth

Foliage: Leaves often blue-green

Leaflets often folded (like a taco shell)

Flowers: held rather high above foliage - and above other annuals

Note: foliage, seeds and pods are particularly toxic

Annual lupines: sun & winter water is the trick

Soils: Texture: most, but do best in well-

drained sandy or rocky soils

pH: any local

Light: full sun

Water: Winter: needs adequate water for

good growth; supplement if needed

Summer: none after pods develop

Fertilizer: none; like poor soils

Succulent Lupine – Lupinus succulentis

Other names: Arroyo Lupine; Hollow-leaf Lupine

Grows in open and disturbed areas, grassy slopes < 2500 ft

Roots: 3 ft; nitrogen-fixing

Flowers: mostly blue, but may be pinkish or white

Pollinators: bees

Food source for: hummingbirds, larva of various butterflies, bees

Self-sows easily if seed falls on bare ground; can remain in ground for years waiting for good winter rains

Garden uses for mid-

size annual lupines

For their wonderful blue-violet color Unusual color for sun-lovers; most good

blues are in shade-loving native annuals Combine with yellow-flowered annuals

for an eye-popping show

In gardens featuring Coastal Prairie, Coastal Shrubland, CSS and desert plant palettes

For dune/slope stabilization

Combine with their usual partners: annual wildflowers (CA poppy; Owls Clover), bulb/corms and native grasses

Look absolutely fabulous massed

And great candidates for pots

Summer Lupine is well suited to water-

wise summer gardens…

Soils: Texture:

Just about any;

Well-drained is best, but takes anything from sandy to clay

pH: any local

Light: full sun

Water: Young plants: good water first year

Winter: needs adequate; supplement if needed – take care not to over water in clay soils

Summer: best with none/little (Zone 1 or 1-2 best; 2 in sandy soils); withhold after flowering
