It’s Lupine Time

In the local prairies, it is an especially prolific lupine blossoming year. Do you have a favorite place to visit lupines? The most prolific, bright, large flowered annual lupine in our area is called sky lupine, because when it is in full bloom in large fields, it looks like someone turned the world upside down. The scent is heady- it smells purple. For those of us who grew up smelling purple in grape Kool Aid or various artificially flavored grape bubble gums, it makes sense that sky lupine smell purple. In good years, I am able to go to my favorite lupine patches at just the right time when acre upon acre are giving off that scent and making extensive mats of lupine colors.

Lupine Diversity

Lupines are pea family plants. Look carefully, and you’ll recognize that sweet pea shaped flower. Lupines typically have flowers in a spike of tightly packed whorls with older flowers turning to seed pods at the bottom and new flowers opening at the top. Lupine seed pods look like pea pods. Sky lupine pods explode on warm days pitching seeds far from the mother plant.

Sky lupine isn’t the only lupine around, there are many lupine species in Santa Cruz County. It might make a good treasure hunt to try to see them all. According to Dylan Neubauer’s Annotated Checklist of the Vascular Plants of Santa Cruz County, California (every naturalist in the County should have this), there are sixteen lupine species in our tiny county. Sky lupine is the only one to make a big show in the grasslands.

Who Eats Lupines?

Italians eat lupines! Strains of white lupine, Lupinus albus, have been cultivated for food throughout Europe. But you have to grow the right strain- some strains are very toxic! In fact, most lupines are toxic…

Here’s a challenge: find sky lupine leaves that are being eaten by a butterfly or moth caterpillar! In researching this essay, I explored the possibility that some beautiful butterfly larva fed on sky lupine. Nope! Lupines famously have some potent toxins. Some species of lupines poison cattle, though I’ve not heard that livestock owners are concerned about sky lupine around here. There are some butterflies and moths that feed on perennial lupine bushes locally, but none that we know of that feed on sky lupine.

Lupine Pollinators

It isn’t a burden to sit in a sky lupine patch to watch for pollinators. You’ll quickly realize that bumble bees love lupine flowers. And, if you look at those bumblebee legs, you’ll see the distinct yellow orange sky lupine pollen color – they collect big globs of it.

And yet, sky lupine doesn’t need a pollinator, it can self-pollinate. But sky lupine flowers make more seed if they get pollinated by bees. The species has an interesting adaptation- some tiny hairs that prevent self-pollination at first; these hairs wilt with time, allowing self-pollination if all else fails.

Planting Lupines

You might be tempted to plant sky lupine- certainly expensive wildflower mixes contain this species and display its color on the fancy seed packets. However, its not that easy. Sky lupine seeds are tough and unpredictable to germinate. Friends have been sending me pictures from places they’ve never seen sky lupines before- the seeds have been in the soil for decades waiting for the right year to germinate! Check out the seeds, sometime- they are beautifully marked with a shiny, waxy seed coat. The seeds are hard as rocks, meant to last years in the soil.

There are many different types of sky lupine, each adapted to its own microclimate. So, if you really really want to get some sky lupines growing, get to a patch nearby and get local seed- collect the pods as they start to dry. Place the drying pods in a paper bag in the sun and wait. Soon, you’ll get to hear the pods exploding in the bag and you’ll know that you got some good seed. Make sure that the pods and seeds are nice and dry before storing them until next fall. As the first rain storm is predicted, cast the seeds around where you want sky lupine…rake them into the soil if you can…and wait- sometimes for years!

Lupine Places

Back in the early 1900’s, many regular Santa Cruz citizens would enjoy Spring wildflower trips to the North Coast grasslands to collect wildflowers. They would bring bouquets home with them and garland their hair and clothes with colorful displays. Now, with long mismanagement of many of those grasslands, there are few wildflower patches left. Anyway, if you do find wildflowers, you’re not supposed to pick them anymore. We ought to leave them for whatever remnant populations of rare pollinators might be around, waiting for us to figure out how to better manage the prairies.

Locally, two places to visit sky lupines come to mind. It used to be that the Glenwood Preserve in Scotts Valley had good sky lupine displays, but I haven’t had a report this year. A little drive to the south, and spring always brings great sky lupine displays in the grasslands and oak savannas of Fort Ord National Monument. There’s something particularly appealing to me about the large patches of sandy grasslands full of lupines surrounded by gnarly short coast live oaks at Ft. Ord. Those sky lupine patches are frequently large enough to get that lupine smell, experience that upside down world with the sky on the ground, and thousands of bumble bees bopping around the flowers.

Luscious Late Rain

After the driest first quarter of the year on record, rain sweet rain fell like no one had predicted this past Sunday. Mark Lipson recorded 1.18” of rain – enough to saturate the first foot of our kind of soil. Maybe some water leaked below that, but it was very dry much deeper than that recently, so the water helps the cover crop, which will quickly drink it up while growing a few extra inches.

The recent nights have been chilly. The breezes have been blustery. We had spring a while back but it then returned to winter, and then the fog today seemed like summer. Atmospheric mayhem.

Field Management

We are mowing. Field after field is getting treated to different mowers, flail or rotary, grinding up cover crop to a sweet-smelling pulp that is already getting eaten by earthworm and sow bug to soon enter the soil food web or at least somewhat cover the soil through the coming dry hot summer. We are retiring fields long farmed as Molino Creek Farm scales down for the first time in decades while we re-envision the next generation of farming the best of our deeper soiled flat land. How shall we manage fallowed fields? This, too, we must contemplate.

Orchard Haps

In the orchard, we are struggling to drop the irrigation lines, test the pressure, flush the pipes, and start up the long process of re-wetting the dry soil before the trees get thirsty. We had to set up irrigation in tall grass that we normally mow first- we must act quickly so trees don’t dry out as they burst into bloom and unfurl their sun-loving leaves.

Orchard understory cover crops, which were so disappointingly tiny, will now grow a bit more. The rain and irrigation spur the more lush growth of purple-flowered vetch, floppy bell beans, and pointy-leaved, thick stemmed oats. Before the rain and before the irrigation, the cover crop canopy was around 6”. Now we can hoo-ray and dance as it grows to more than a foot of valuable green manure to feed the pollinators and fertilize the earth.

Critters

The cold and rainy times chilled the turkey vultures or perhaps they were doing something more. Out there in one freshly mown cover crop field two vultures faced the freshly emerging early afternoon sun, lifted their lovely red fleshy heads and spread their giant wings out as if to soak in the rays. It always seems like such an effort to keep those huge wings held out parallel to the ground. Later, there were four vultures struggling to get altitude in the intermittent gentle breeze. Up and up they went and then there was an unusual sight- one after the other they folded their wings and jetted downwards at one another. Swoosh! You could hear the air cutting across their giant wings a hundred yards away. Playing? Mating rituals? Wow.

Speaking of turkeys, our road intersection hen was so fat with eggs 10 days ago that she could hardly walk fast. I patiently gave her berth as she walked up the Big Hill in front of my truck. Her feet seemed to hurt her, and she wobbled to and fro. After a long, long ways she (finally!) moved off the road towards her normal nesting spot. 4-17 eggs have been laid somewhere nearby. Expect the little ones to be fluffing around in about a month, just like every year for many. They are our welcoming party as you turn into the Farm.

A week ago this past Sunday, around 10 p.m., the slightly open window revealed the repeated bouts of screaming from a lioness not far from the house. That sound is always invigorating. She went on like that for an hour or so before quieting down. No noise since.

The golden crowned sparrows are still hanging around. Hummingbirds are diving and flashing. Quail coveys flock together.

Bright Spring Flowers

The rain will make the lupines even happier this Lupine Year. The bush lupines are in full bloom, big patches of green-blue velvety mounds with thick spired masses of checkered lavender and white flowers. There are two types of annual lupines- the tiny flowered bicolor lupine and the full flowered deep blue sky lupine (aka someone turned the world upside down lupine). These annual lupines are incredibly gorgeous. 10 a.m. in the North Orchard and you can bathe in the sweet scent of purple as lupine flower essence wafts downwards from 3 acres of flowers, floating towards Molino Creek Canyon.

Sky Lupines carpet acres this spring – very unusual profusion!

Heat waves and chilly nights

Heat waves and chilly nights, hills drying in what is becoming one of the driest February months on record…after an extremely wet December. After the orchard workparty last Saturday, we stood on a hillside overlooking the farm to be intermittently chilled to shiver and warmed as if by a nearby fire. There were alternating breeze directions ushering in big pillows of air with vastly different temperatures.

To our human senses, the world sometimes seems upside down and the same is true for non-human organisms. Living things share the same genetic structure, allowing us intergenerational memory and the potential for adaptation. Global weirding isn’t just about climate disruption, it is a symptom of human disfunction, feeding psychological malfunctions, creating disequilibrium, mayhem and chaos.

Fire’s lessons

Organic farms like ours rely on creativity. Instead of turning to the newest synthetic chemical pesticide, one of the many creative tricks we use is conventional breeding and plant selection to select stronger plants, taking advantage of the creativity of DNA. Our orchard is planting trees bred for disease resistance.

Once the plants are in the ground, we provide them everything they need for maximum health, creatively experimenting with new foods, including concoctions that feed the ecosystem that supports the crops.

As much as organic farmers creatively produce food, we live in evolving natural systems and we are challenged to constantly adapt. What can we learn from Nature?

Lupines

The wildfire triggered germination of thousands of lupine bushes in the habitat areas we steward around our farm. Years ago, two of our members requested that we nurture these bush lupines, mowing and clearing around them. This was one instance of these partners’ contribution to the pool of collective creativity, nurturing beauty that turned out also to be post-fire habitat, pollinator support, and erosion control.

Just now, we are seeing an eruption of tussock moths that love to eat bush lupine leaves. The moth caterpillars will feed Western bluebirds and many other beautiful, feathered friends. The frass that the caterpillars drop will feed other wildflowers and native grasses, diversifying the hillsides.

Learning from Nature

From fire to lupines, from lupines to pests, and then from pests to birds and fertilizer…these are a few of Nature’s cycles. What might we learn from these cycles? Because farmers must be keen observers of nature, we tap into this type of ancient wisdom. As co-owners of a beautiful property, our collective is also learning the creativity necessary for evolving and adapting as a group. Cooperatives and organic farms are amazing experimental grounds for solutions to the root causes of the climate crisis.

To tap into the deep potential for creativity embedded in the DNA we inherited from millennia of experimentation, we must turn away from potential-destroying toxins. We must embrace stewarding diversity in the face of the tempting and ‘easier’ monocrop, lest tussock moth-like sieges take place. And, when the pests do erupt, instead of hiding behind toxins, we must invest in deeper contemplation and more complex negotiations, as evolution has long taught us. Until recently, we were taught evolution meant survival of the fittest, but now we understand that cooperative relationships are the key to success. Mutualism. Symbiosis. We have so much to learn.
