Give a seed the right conditions ……. enough water, sunlight, the perfect temperature ….. and this small package cannot resist emerging from its protective coat to grow into a full grown plant.
Seeds are tiny marvels of nature.
Looking inside the seed reveals a miniature pine tree!
Think about it ……. a seed is really a living baby plant (the embryo) surrounded by a cozy blanket (the endosperm) that cradles and nourishes the embryo while tucked inside the seed coat. When the coat unzips, freeing the “baby” as it begins to grow, it continues to be nourished by the endosperm until the first true leaves appear. Witnessing the process is so cool!
After collecting piñon seeds from last November’s foraging expedition, (Piñon or Pinyon, Piñon Seed or Pine Nut), we decided to treat a dozen or so to conditions just right to stimulate germination. But first the seeds required a short period of stratification (moisture) to help soften and crack the seed coats. Introducing moisture was done by lining a clear glass jar with damp paper towels and placing the seeds between the towels and glass to watch the action.
Post from November 2024 Seed Foraging Expedition
Soon embryonic roots (the radicles) successfully cracked the seed coats of nine seeds and began growing downward, as roots tend to do. In a week or so, before the embryonic leaves (cotyledons) appeared, all of the germinating embryos were planted. Six of the nine then sprouted their whorled cotyledons, followed by a growth spurt of the first true leaves, initiating the process of food manufacturing (photosynthesis).
Steps to Germination
All of the germination and seedling development details of these piñon seeds, to date, can be found in my update illustrations.
Seed germination is a fascinating process, and like the seed itself, is also a marvel of nature. Have you ever tried to germinate a seed? If not, give it a go. It’s fun, educational, and imagination provoking ….. from such a small seed comes a full-grown flowering plant!
Wandering about the neighborhood one warm summer morning in 2018, I noticed a dense stand of plants lining a 20 foot section of road. What caught my eye were the umbrella-like clusters of pearly white flowers topping each slender stem. From a distance these plants resembled our native white-flowering yarrow. But I soon realized the narrow dark green leaves were not fuzzy; the tiny exotic-looking flowers were not daisy shaped. Unmistakably, this plant was a species of milkweed! And the flowers of more than 50 individual plants in this population were a-flutter and a-buzz and a-crawling with hungry insects!
What was this milkweed species?
This is the Winter Botany portion of this post. All that remains of last summer’s Horsetail Milkweed are stems and mostly empty seed pods clinging to short branches. But some of the seed pods still hold silky tailed seeds clinging to their open pods. Hundreds of seed pods line the roadways in our neighborhood.
It didn’t take long to confirm this plant as Horsetail Milkweed (Asclepiassubverticillata), a species commonly found along roadsides in pinyon-juniper woodlands. Knowing what to look for on future walks, over the next several years I was excited to find 30+ more populations of various sizes along neighborhood roadways! From 2018 until early summer 2024, I continued to monitor these seemingly abundant populations. The small numbers of seeds I collected in the Fall were planted in our yard, and every year I checked for the presence, variety and numbers of insects busy feeding on nectar as they pollinated the flowers.
During June 2024, when we moved only a few miles to the northeast, I was happy to see Horsetail Milkweed grew abundantly in our new subdivision. This prompted me to dig deeper into researching this species. Its been exciting to discover how important this milkweed is to native insects, including monarch and queen butterflies.
Photo (mine) taken in July 2022 of a blooming Horsetail Milkweed being enjoyed by a feeding wasp.
According to pollination ecologists, Horsetail Milkweed is especially valuable to large numbers of native bees. This plant species also supports conservation biological control by attracting predatory or parasitoid insects that prey upon pest insects.
And Horsetail Milkweed is one of the favorite host plants for monarch and queen butterflies, all because it’s toxic! Producing an especially nasty tasting and potent neurotoxin strong enough to kill livestock, the caterpillars of these two butterflies have evolved to benefit from such a poisonous substance. Voraciously ingesting a diet of only milkweed leaves, obviously tasty to the larvae, makes them unpalatable to would-be predators, such as birds. The toxin from milkweed leaves has become their primary means of defense; definitely a benefit for such chubby, slow little caterpillars.

Although central New Mexico isn’t in any of the major migratory routes of these butterflies, I have observed both species in our previous neighborhood. Since learning more about Horsetail Milkweed and it’s favored roadside habitat close to home, my hope is to provide actively growing plants throughout the summer (a safe distance away from roadside easements) for both the monarch and queen adult butterflies and their caterpillars ……. especially important when governing covenants of our previous and new subdivisions require the roadways be groomed (mowed down like a butch haircut!) on a monthly basis by subdivision landscape crews.
Because milkweeds are among my favorite of all plant species, mainly due to their complex flowers and the clever trickery they’ve developed to ensure pollination, I wrote about and illustrated two in-depth blog posts on this subject. Believe me when I say, “It’s overboard fascinating!”
Summer Botany: Meet the Milkweeds from July 2022. This is my first comprehensive look at milkweed flower structure, how pollination takes place, and the genus Asclepias.
Read on to learn more botanical information about Horsetail Milkweed AND how to find out if you live in Spring and/or the Fall Migration routes of the monarch butterfly AND where queen butterflies migrate to and from.
Characteristics and habitat requirements of Horsetail Milkweed
Horsetail Milkweed is a perennial species with a stout, woody rootstock. Plants readily spread by rhizomes (underground stems) producing dense communities. Cold-hardy to at least 0℉, this milkweed bounces right back in the Spring. Plants are also drought-tolerant once established, thriving in well-drained, sandy soil under full to partial sun.
Able to thrive in a variety of habitats and plant communities from 2500 – 8000 feet in elevation, Horsetail Milkweed grows among grasses, on sandy or rocky flats, on slopes, roadsides, and along trails in Chaparral, Semidesert Grasslands, Pinyon-Juniper Woodlands, Montane Conifer Forests, and in disturbed areas.
All of these characteristics and its adaptability to a wide range of habitats make Horsetail Milkweed one of the easiest milkweed species to grow.

Monarch Butterfly
To learn if you live within the path of or close to spring and/or fall monarch butterfly migration routes, you can view a map or these route here:
The queen is chiefly a tropical species. In the US, it is usually confined to the southern portion of the country. It can be found regularly in peninsular Florida and southern Georgia, as well as in the southern portions of Texas, New Mexico, Arizona, and California. Occasionally, the subspecies of the queen can be found somewhat north, in Kansas, Colorado and Utah.
Queen butterflies do not migrate as dramatically as monarch butterflies, but they do move short distances in tropical regions with dry seasons to higher elevations.
Winter can be challenging for nature journalers. Getting outside when it’s cold and windy, cloudy and dreary, snowy, icy or wet, are not ideal weather under any circumstances. And when everything looks brown and crispy and pretty much the same, the challenge to nature journal in the great outdoors grows exponentially. While these conditions make it difficult for spontaneous observing, I try to remember there’s always something remarkable to be discovered in nature, even in winter.
Who knew a little whack on the head would be just the thing to reawaken my curiosity?
Bundled in layers, leash in hand, Luna led me on her early morning walk around suburban Albuquerque. Having been along this route before, we’ve both made some interesting discoveries in the past. And as usual, this time was no exception for Luna. For me though, everything appeared brown, crispy and familiar. But I was inspired by and enjoying Luna’s sense of curiosity, and her encouraging tug on the leash.
Nearing the end of our 2-1/2 mile walk, and mightily concerned I’d go home empty handed, we turned our last corner. It wasn’t 100 feet down the cement block-lined sidewalk that I abruptly stopped in my tracks. Something had lightly whacked me in the head! While the sound of rhythmic clacking rang out, I looked up, and to my surprise spotted the accidental assailant. Draped over the 6 foot wall, suspended from a hearty Trumpet Vine (Campsis radicans) growing in the hidden yard beyond was a string of pods resembling brown green beans. Long and plump and full of seeds, one of these pods had reached down low enough to make contact with to my head. (I say “reached” because that’s what my imagination said had happened.) Quickly awaking my sleepwalking brain, the effort made by the seed pod to get my attention paid off too. Silently whispering, “Pick me! Pick me!” it was as if the seed pod and its adjacent buddies either wanted to be harvested, or wanted to be featured in my nature journal (or both).
So I did ………… both!
I loved learning about and sketching these fascinating Trumpet Vine seed pods, while my mind was filled with the muffled notes of a trumpet. Tooo-too-too-toooooom!
Hope you enjoyed reading this story and browsing around my journal pages.
After an unseasonably warm, almost spring-like December in the mountains of central New Mexico, January clearly has something else in mind. Winter! Windy days have resulted in bitter cold as they brought us cloud-cover and a few mini-snowstorms.
The change in weather and absence of wildlife, combined with an abundance of dried vegetation is making it challenging to find nature journaling subjects. So a few days ago, I followed Luna around to see what was capturing her attention. Turns out burrowing rodents expanding their underground tunnels are leaving behind fresh mounds of soil with fascinating odors (to Luna, at least; I couldn’t smell a thing).
When one of her explorations led me under a good sized pinyon tree, I noticed a very interesting piece of bark lying on the ground. Turning the piece over and over, examining all the beautiful patterns in the wood, the colors, old bug holes, and woodpecker drillings, I was surprised and delighted to see a good-sized hole in the shape of a perfect Heart! Eureka!
The 7” piece of pinyon bark …. Can you find the Heart?
Many things crossed my mind in that moment …… but the one word that stuck was “Heartwood!!” Could this small piece of bark redefine the meaning of heartwood? Could this tree have been wearing it’s true emotions on its bark in the form of a heart-shaped window?
After a refresher on basic tree anatomy, and reconfirming that heartwood surrounds the core of the trunk, my imagination went wild. Could that heart-shaped hole in the bark been the opening of a mysterious pathway through the inner workings of the tree?!!! If I could’ve returned the piece of bark to the exact place from where it fell, could the heartbeat of the tree be heard?
My finished pages mostly about Redefining Heartwood, but also featuring the view of South Mountain (to the NE) as seen from our new home (including my studio) and the trail where the “Heartwood” bark was found.
While sketching the piece of bark with its perfectly-shaped heart, I wondered if peering at the inner workings of a tree through this window would make a fun children’s picture book? ….. Where the layers of a trunk and how they work would be experienced first hand by a child walking down the pathway?
After you stop laughing from all this nonsense, let me know what you think?
As always, thanks for stopping by (on my magic carpet ride!)
In November 2023, I created a journal page of seeds and seed pods, which posted on 12/14/2023, under the title November Littles: Seeds, Pods, Silk, and Wings. On that page was a small drawing of two Fourwing Saltbush seeds, absent any information about this plant species, Atriplexcanescens. At that time I remember finding a wealth of articles and research documents about this widespread shrub, but what really stuck in my mind was a very unusual quirk exhibited by this plant. Finally, a year later and WOW! I discovered Fourwing Saltbush has a reproductive superpower …… this species has the ability to change sex!
An Unusual Quirk
My first dive into the literature revealed that within a 7-year period of time, 40% of a Fourwing population switches sexes with 20% of a population changing sex every year. Botanically, this is known as Trioecious, or the 3rd Sexual State.
But clearly a bit of back peddling is needed ……. if Trioecious is the 3rd Sexual State in plants, what about the 1st and 2nd sexual states, huh? Yes, they exist …….. but before explaining them, which requires comparison with the more common sexual state in plants, I must describe this sexual norm.
And now for a little Botany 101 ……..
The Sexual Norm …… Plants with Perfect or Complete Flowers
You are likely familiar with plants like roses, tulips, lilies, garden strawberries, beans, peas and cabbage. If you’ve closely examined their flowers while inhaling their fragrant aromas, you may have noticed their centers have both female and male parts. These are known as plants with Perfect or Complete flowers (aka hermaphroditic or bisexual) defined by each individual flower having a fully functional pistil (the female part) and stamens (the male parts). Worldwide, about 90% of flowering plants have Perfect or Complete flowers.
Monoecious ….. the 1st Sexual State
Here again you are likely familiar with many plant species described as Monoecious (moh-NEE-shuhs). These include corn, all of the plants in the gourd family (i.e. cucumber, squash, watermelon), oak, birch, pine, spruce and dogwood. Monoecious, which means “one house” in Greek, describes plants having separate female and male flowers in different places on the same plant, often blooming at different times. Visualize corn growing in a field; the tassels are the male (staminate) flowers, and the corn kernels you eat are the female (pistillate) flowers. Around 10% of all flowering plant species worldwide are Monoecious.
Not to confuse the matter, but sometimes botanical experts refer to Monoecious species as Perfect or Complete because they have both male and female flowers on the same plant, even though these flowers are separate and considered sexually Incomplete (aka unisexual) by themselves.
Dioecious ….. the 2nd Sexual State
A plant species with individual plants in a population having only female flowers, and individual plants of the same species in the same population with only male flowers is called Dioecious (dahy-EE-shuhs). This Greek word meaning “two houses,” describes plants such as spinach, asparagus, sumac, currant, box elder, willow, holly, ginkgo, juniper and aspen. Only 5% of all flowering plant species worldwide are Dioecious.
Another confusing matter once again. There are botanical experts that refer to plant species with Perfect or Complete flowers as Dioecious because they require cross-pollination to produce seeds (fruit). Tree fruit species such as apples, pears, cherries and plums are common examples.
Trioecious ….. the 3rd Sexual State
An extremely rare reproductive strategy among flowering plants, Trioecious (aka trimonoecious or “three houses”), is characterized by a species that can have Incomplete (unisexual) male, Incomplete (unisexual) female, and Perfect or Complete (bisexual or hermaphroditic) male/female flowers on separate plants in a population or even all on the same plant! Just over 3% flowering plant species worldwide are Trioecious (trahy-EE-shuhs).
This is where Fourwing Saltbush (Atriplexcanescens) enters the story
Primarily a Dioecious species, some Fourwing Saltbush populations have a Monoecious component ranging from entirely male (staminate) or female (pistillate) individuals to those that are Perfect or Complete (hermaphroditic or bisexual). And in this Dioecious–Monoecious–Hermaphroditic gender system, referred to as Trioecy, switching sexes occurs. To reiterate from an earlier paragraph, on average, in a 7-year period, about 40% of a Fourwing Saltbush population switches sexes with 20% changing from male to female or from female to male every year.
Reasons Behind and Benefits of Fourwing’s Sex Change Phenomenon
Fourwing Saltbush has evolved to be one of the most adaptable plant species found throughout central and the western US. It grows from sea level to 8500 feet elevation, and in a multitude habitats within a wide range of plant communities, no matter the successional stage. Fourwing can adapt to all soil textures, soil depths and all but the wettest of soil conditions. The species is able to tolerate hot (+100F) and dry (6” precipitation annually) summers, and bitter cold (-50F) and dry winters.
The ability of the species to adapt to such a wide range of physical and climatic conditions is, in part, due to this sex change phenomenon. Environmental stressors seem to be the major triggers resulting in Fourwing plants switching sexes. Female plants are more likely to change sex than male plants, especially following a drought, an extremely cold winter, or after a heavy fruiting season. Because fourwing is so tasty as range forage, overgrazing can also trigger a sex change, with male plants tending to dominate regularly grazed sites. Male plants that change to female typically flower earlier than plants that remain female season after season. And female plants dominate richer sites than do male plants, becoming larger and producing more seed.
Undoubtably there’s more environmental stressors, such as wildfire and other climate change-induced factors, that may result in Fourwing Saltbush to switch sex. I’ll be curious to learn what they are and how these triggers influence the adaptability and survivability of this robust species. And I’m excited get busy marking this season’s female and male plants that we see nearly every day, and will begin more closely observing these populations for gender changes and possible stressors that may have triggered these switches.
A Retrospective and Thoughts on Prospective Studies
There’s so much to learn about Fourwing Saltbush that it seemed logical to tackle one characteristic at a time. Originally I had planned to discuss both the plant’s reproductive quirk and several of its common galls, but found there would be too much information for one post. While deciphering the complexities of the Fourwing’s sex change abilities, I found it necessary to describe certain key botanical terms in my buildup to the crucial piece of the puzzle ….. the Trioecious reproductive strategy. So this post focused on the first of my two journal pages; my beginning exploration into this plant. The galls illustrated on my second journal page, that could not be easily chopped away from the first page, serve as a preview of a future post about the fascinating Fourwing Saltbush.
And Finally ……….
For a shrub I used to describe as a messy tangle of branches haphazardly cloaked with unremarkable features like dusty little grey-green leaves, nearly invisible flowers, shreddy dull grey trunks and a chaotic canopy, Fourwing Saltbush has captured my imagination, respect, and love as an almost invincible survivor of our changing world!
Hopefully you found this interesting and informative. Bet you never look at flowering plants in casual ways again. Let me know if you are familiar with Fourwing Saltbush. Where does it grow? Have you ever marveled at the thousands of winged seeds densely crowded at the tops of these shrubs? And then satisfied an irresistible urge to strip dozens of skinny branches of those ripe seeds, tossing them in the air like confetti? If so, please share.
It’s late October, mid-Fall in the Manzano Mountains, perhaps a week before the first snow of the season. The Gambel Oak covering hillsides and mountains somehow sense a change in the air. Seemingly overnight every leaf on every oak shrub and tree magically transformed from their summer greens to royal rusty reds, gleaming golden yellows, and shocking sunset oranges. As I look across the landscape and marvel at the sight, I can’t help wondering, “How do they know?”
The spectacle is short lived. Over the next few weeks, these gorgeously painted leaves slowly change to crispy beige brown, fooling the observer into believing they can’t face another winter; that every single oak shrub and tree just gave up and died! Thinking that was the case my first winter in central New Mexico, I was fooled. But since then I’ve learned a lot about the life cycle of Gambel Oak, and have come to appreciate the persistence of all those crispy browns covering up the otherwise barren nakedness of chaotically jumbled branches.
There’s a lot that can be said about Gambel Oak (Quercusgambelii), but this post focuses on
The Leaves of Quercus gambelii
The most interesting thing about this oak species’ leaves is no two are alike. Even though each leaf looks different from its neighbor, they do all have common characteristics that distinguish its leaves from other oak species. For example, All Gambel Oak Leaves …….
are lobed (but the number of lobes varies from side-to-side of a leaf’s mid-vein; depth of lobes varies on a single leaf and between leaves; lobes can be gently concave to acutely angled).
are flat and leaf margins are smooth (if leaves appear somewhat wavy and/or exhibit some serrated margins and/or points on the lobe tips, this is not a true Q. gambelii, but likely a hybrid of Gambel Oak and Shrub Live Oak (Q. turbinella) resulting in Wavyleaf Oak (Q. undulata), very common where ranges converge).
are different lengths and widths, and leaf sizes are random along each branch, with large leaves adjacent to small ones adjacent to tiny ones adjacent to gigantic ones, etc.
change color in the Fall, eventually becoming beige brown and crispy (but color patterns on individual leaves and throughout a shrub/tree are wildly various; some leaves turn one color, while others become a mixture of greens, reds, yellows and/or oranges).
that are brown/crispy persist on the shrubs/trees throughout late Fall and Winter, then drop all at the same time in Spring when buds begin to open.
that are fresh have little 5-star hairs on the undersides, while the upper surface is smooth and leathery.
are relatively free of insect damage, with the exception of the occasional oak gall or insect nibbles (perhaps due to their leathery texture on the upper surface and hairy texture on the undersides?).
Every Fall I observe and collect Gambel Oak leaves. They make great subjects for my nature journal! Because every leaf looks different, the easiest way to depict the various shapes is to trace their outlines directly onto my journal pages. Then with leaves in hand, I can use my Inktense watercolor pencils to paint within the outlines, spending most of my effort on their beautiful colors.
I hope you’ve enjoyed my page of Gambel Oak leaves. Do you share nature with oaks? If so, which species, and are their leaves all the same or different somehow? Do you record your observations in a nature journal too? I’d love to know!

Pine Nuts Come From Where?
Many years ago, maybe about 45 of them, Roy and I, his sister and her husband, set off on a pine nut safari in the mountains of south central Colorado. They knew of a large stand of a specific pine tree, called Pinyon (Piñon**) heavy with cones and ready to harvest. This was my first encounter with the Colorado Pinyon Pine (Pinus edulis), and my first taste of the buttery rich tear-drop shaped seeds produced by these trees. I was hooked! After 4-5 hours collecting wide open seed stuffed cones from low hanging branches and off the ground, we had to stop. Our fingers were impossibly stuck together from the cones’ copious coating of resin, definitely stickier than Super Glue! Without a solvent to dissolve this adhesive pine tar, we were in danger of losing our fingerprints.
Having made a less-than-minor dent in the harvestable nuts, ample quantities of this energy rich bounty remained for foraging wildlife, such as migrating birds like pinyon jays, deer and squirrels.
For the past 45 years I truly believed pine nuts (which are, botanically speaking, not true nuts but the edible seeds of pinyon pines) only came from stands of Colorado Pinyon Pine. When the popularity of pesto skyrocketed, I thought “wow, you couldn’t pay me enough to harvest the amount of pine nuts necessary to make even one batch!” I honestly thought that was the reason the seeds were so expensive ….. harvesting is such a tedious and labor intensive job. Alas, we never returned to harvest pine nuts, and I never made pesto until years later.
The result of my Pinus edulis cone and seed sketching exercise.
While studying a few dozen pine cones for my sketches, the seeds kept falling out and bouncing across my drawing table. This got me thinking about pine nuts and wondering how the Colorado Pinyon Pine could possibly fill the insatiable global demand! Of course by now I was well aware that this tree species is endemic in the southwest, but still ?…….
News to Me ….
Of the 126 different species of pine in the world, 29 are considered edible; 20 of which have seeds large enough to be marketed. The biggest producers and exporters are China, Russia, Mongolia, Turkey, and Pakistan, in that order. I found it interesting that China is also the largest importer of pine nuts, who’s marketing goal is to export 60% of the world’s demand.
What about the US? The pine nuts harvested from Colorado Pinyon Pine (Pinus edulis) is rated the best tasting in the world, with those produced by the One Leaf Pine (Pinus monophylla), harvested primarily from these California trees, comes in a close second. Yet, the US is a major importer of shelled pine nuts, primarily from China. But if China is the largest importer and the largest exporter of shelled pine nuts, then the pine nuts on the shelves of Trader Joe’s and Costco, labeled as imported from China, probably came from a variety of pinyon species from a combination of suppliers importing seeds to China?!
Being naturally curious about the Pinyon species that grow in various countries around the world, I included a list of 16 of the most commonly harvested trees the end of this post.
What’s the Real Reason Pine Nuts are so Expensive?
It’s said that “pine nuts are the most expensive seeds we would never buy!” (**** Check out this footnote for the 2024 costs/pound and my random calculations per serving and for a batch of pesto). Pine nuts are the second most expensive “nut” in the world, second only to the macadamia nut. Butwhy? While it’s true the seemingly exorbitant price of shelled pine nuts is directly influenced by labor costs, compounded by the annoying sticky factor, other challenges exist.
Harvesting Pine Cones
Cones are harvested by hand, directly gathering those that have fallen on the ground, and from tree branches (where the densest number congregate in the upper 1/4th of 30 foot tall trees). Another common harvesting technique is to whack the branches (which reportedly does not injure the trees [hmmmmm?]). But a faster method used in many countries is to cut off branches with cones, resulting in a number of detrimental effects to the trees (open entry points for insects and pathogens; stunted growth; stalled production; tree death).
A sampling of Pinus edulis cones with hard coated seeds removed, ready for cracking. There’s a single kernel between the two lower right cones.
Pine Nuts
Once the seeds are taken out of the cones, their hard shells (seed coats) must be removed without damaging the soft edible kernels inside, the “pine nuts.” (And not every seed is viable ….. more about that below.) The shelled pine nuts must now be handled quickly and properly due to their short shelf life. It only takes a few weeks or even days in warm and humid conditions for shelled pine nuts to lose flavor, turn rancid, and completely deteriorate. Until they can be marketed for export, pine nuts must be kept frozen. Ideally, shelled pine nuts should remain frozen during export/import and until consumer purchase and consumption.
There were the remains of the Pinus edulis seeds extracted from these cones; 30 tasty kernels were viable; 20 were either missing or dried up.
Tree Characteristics
Slow growing trees and inconsistent production are several more reasons pine nuts are so expensive. Pinyon pines are notoriously slow to grow, mature (10 years) and produce a harvestable crop of cones with viable seeds (75-100 years). But pinyon pines typically live an average 350 years, and have the potential to produce tons of harvestable seeds. However, all pinyons exhibit a common characteristic called “masting,” where they may produce a bumper (harvestable) crop only once in as many as every eleven years. Good years are not predictable either, as many factors influence growth and production, with local droughts and a changing climate having the biggest impact.
Gifford Pinchot (1909), U.S. Forest Service Chief said: “Seasons of especially abundant production occur, as a rule, at intervals of from five to seven years, although heavy crops are sometimes produced for two or three consecutive years, and heavy seed years are not the same throughout the range of the tree.”

______________________________________________________________ A Few Footnotes
**Piñon or Pinyon?
The most common common name for Pinus edulis is “Colorado” Pinyon Pine, even though the species is widespread in New Mexico, Utah and Arizona as well as Colorado. The words pinyon and piñon are usually considered interchangeable. Use of the word “piñon” (Spanish for pine nut) is tied to the seed (i.e. piñon seed or pine nut seed) and the tree (i.e. piñon pine or pine nut pine) particularly used by Native Americans in the southwest US. Because references consulted during my research were not consistent in their use of common names for Pinus edulis, to avoid (my) confusion I’ve opted to call the piñon seed (pine nut seed) a “pine nut” and the pine trees with edible seeds “pinyons.”
**** The 2024 retail market cost (shelled raw or roasted seeds) averages $40/pound
1 pound of seeds = about 4 cups (depending on seed size)
1 cup of seeds weighs about 4 ounces (price $10§)
1 ounce or 1/4 cup of seeds = 1 serving (price $2.50)
1 serving = about 167 seeds (price 1.5 cents/seed)
167 seeds = 191 calories (pine nuts are extremely high in unsaturated, heart-healthy fats and carbohydrates)
1 cup of seeds = about 668 seeds = 764 calories
4 cups of seeds = about 2,672 seeds = 3,056 calories
Number Play
Of the 50 seeds I harvested, only 30 were viable (price 45 cents)
It took me about 45 minutes to crack open the 50 seeds (this doesn’t include the time it took to collect the resin-coated cones and remove the seeds)
It would take me 67 hours to fill a 1 pound bag with 2,672 viable shelled seeds!
At $40/pound, a pine nut cracker would be paid only $0.59/hour for their labor, a wage earned back in the 1950’s and 1960’s which didn’t even come close to supporting a family then, let alone today.
Assuming a pine nut cracker makes a minimum wage of $7/hour, it would cost $468 to fill a 1 pound bag. That’s 1,170% more than the 2024 retail cost of a pound of pine nuts!
Obviously, a professional pine nut cracker is far more efficient than I was, using some form of mechanization to crack the seed coats (requiring more research on my part).

§Pesto ……. most pesto recipes I found call for the addition of 1 cup of shelled pine nuts, or 668 seeds. At 1.5 cents/seed, you’d be adding $10 of pine nuts to make one batch of pesto. Enjoy slowly!
Living in the East Mountains of central New Mexico ensures daily appreciation of hundreds and hundreds of Piñon Pines (Pinusedulis). This iconic pine, the state tree of New Mexico, has been a source of nutrient rich seeds for wildlife and indigenous peoples for millennia. It was fun learning more about this tree and the many Pinyon species that grow around the world.
September 22nd was a morning full of new-to-me discoveries in nature. That was more than a month ago; a time when temperatures were still in the upper 80’s and flowers in full bloom.
But plenty of hints of what was to come ….. the inevitable change in seasons ….. existed. There were seeds of spring and summer bloomers blowing in the wind; squirrels stockpiling pine nuts from recently shed cones; darkling beetles mating and laying eggs in the ground to hatch next year’s population; caterpillars feasting on energy-packed flower petals needed to spin their cocoons; the chortling chatter of sandhill cranes high overhead migrating to Bosque del Apache for the winter.
Still it is hard to believe that today, a little more than a month later, everything has turned brown, and our first hard frost is forecasted for tomorrow morning!
In an effort to cling to a not-so-long ago summer, this small selection of the botanical and entomological happenings on the cusp of Fall, is now a part of my nature journal. Enjoy!
Roy had a doctor’s appointment one morning in late September, at an office right off busy I-25, near the ABQ airport. Instead of hanging out in the sterile waiting room, Luna and I spent our time exploring the areas surrounding the office, just to see if there was anything worth observing.
For 2 miles, we wandered about the not quite urban/suburban/industrial/residential neighborhood ….. me looking for a sketchbook entry; Luna sniffing out messages left just for her by visiting dogs, squirrels, or bunnies.
Interesting discoveries seemed lacking, until Luna caught whiff of something irresistible. Tugging hard on her end of the leash, she urged me to run with her as she zeroed in on the source of the smell.
By a parking lot light, on the pavement next to a cement curb was an explosion of feathers, but Luna kept leading me on to something better. There! Lying on the curb was a still wet and bloody bird foot barely connected to what remained of the thigh. All clues pointed to the very recent drama, where a raptor (possibly a red-tailed hawk) had swooped in and nabbed the hapless victim (a feral pigeon), killed and then ate his prey from the platform atop the parking lot light. The inedible remains fell to the ground as a group of 2 dozen “relieved-it-wasn’t-me” pigeon friends looked on.
Quickly solving most of this puzzle in the time it took to pry the pigeon foot from Luna’s mouth, gave me the idea of sketching not only the foot, but to look for other unlikely nature discoveries in this urban/suburban/industrial/residential neighborhood setting.
Mentally armed with a keener power of observation and purpose, we retraced our earlier route with excitement! Now it was obvious an abundance of interesting and beautiful plants were growing from every sidewalk crack and along crumbled pavement edges throughout the ‘hood. How had I missed seeing these beauties?
And that’s how my idea for this 2-page layout was born, along with a reminder that finding bits of nature doesn’t have to occur at a botanical garden, wildlife preserve or national park. Nature is everywhere. If you just slow down and really look, even in the most unlikely places like sidewalk cracks, there’s always something to discover. So Remember to Explore the Cracks too and let me know what you find!

September 23 – October 7, 2024 For the last 7 years, I’ve participated in the annual, 2-week long sketching/drawing, painting and mixed media event, Sketchbook Revival, founded and hosted by a talented sketchbook artist, Karen Abend. Every year, Karen brings together a cast of creative artists for a mega on-line teaching marathon. Each day, 2 1-hour recorded sessions are available to hundreds of participants from around the world, providing an opportunity to interactively learn a skill or technique designed to begin or expand on a regular sketchbook practice. These sessions may include book binding, mark-making, collage, creating imaginary characters, urban sketching, composition, landscapes, flowers, mammals and bird painting, people or pet portrait drawing, nature journaling, Zentangle, map making, story telling, textiles, and on and on! Techniques shared by instructors involve a wide-variety materials, like watercolor, gouache, acrylic, markers, pencil and pen, colored pencil, and many forms of mixed-media.
The whole fun event is designed to stretch your creative comfort zone by experimenting with art supplies and new approaches to art making, and encourages play. And as incredible as it sounds, all you need to participate is your time and whatever materials you have on hand. Otherwise, it’s totally free! Wowza!
Not every session needs to be done (and this year there were 30 sessions in 15 days); I usually find time to complete about half of them. But this year I did all but one session (and may even complete the one skipped). From the very diverse cast of artists/instructors, I was able to learn new tips, techniques, approaches, and was invites to try new art supplies that would be useful in my regular sketchbooking and nature journaling practice.
Hopefully you’ll enjoy my 2024 Sketchbook Revival “play!” Not all are great or even good (a few are downright awful!) but it was so much fun! Maybe something from my collection will have you laughing, or maybe even entice you to give Sketchbook Revival 2025 a whirl!
That’s all for Sketchbook Revival 2024. Let me know what you think!
