Plants – a curious nature

Davis Mountain Mock Vervain (Glandularia wrightii)

This page shows samples from my specimen.. Although the flowers of my specimens are a purple-blue color, I chose to create the flower petals as reddish-pink; this color is also common.

This is a photo of the two flowers I sketched for my final painting.
The specimen on the left shows the upper part of the flower, the “limb” where 5 petals flair out from the throat ringed by fine hairs. The throat leads to the lower part of the flower – the floral tube (5 fused pale green petals). . Both upper and lower petals make up the flower’s corolla. Below the floral tube are 5 red tipped green sepals (collectively called a calyx) all fused into a cup shape. The specimen on the right is a dissected flower; 2 upper petals are removed, and the floral tube has been opened to reveal the reproductive parts. On the left side are 2 of the female parts of the pistil (pale green style supporting the 2-lobed stigma of the pistil; the ovary was not exposed). Two of the four stamens (male) lie in the mid- to upper right side of the opened floral tube; look for the bright yellow anthers, each sitting atop their own filament

Here’s Another Curiosity to Ponder: I wondered why this plant has 5 petals and 5 sepals but doesn’t also have 5 stamens, which is usually the norm in so many other 5-merous plant species??? Here’s what I learned:

Davis Mountain Mock Vervain (Glandularia wrightii) exhibits a common evolutionary trait in the Vervain (Verbenaceae) family where the flower displays a 5-lobed calyx of fused sepals, and 5 5-lobed petals which fuse into a tube (the corolla). This trait, commonly described as 5-merous, curiously has a reduced the number of functional stamens to four.

This reduction is due to an evolutionary transition from a 5-stamen ancestor. According to literature, the four fertile stamens I observed in my specimens are properly arranged in two pairs (didynamous), both neatly hidden in the floral tube beneath a ring of fine hairs. Also properly so, the filaments (the stalks that support the anthers) of the stamens are fused to the inside of the tube, and not easily teased free.

So apparently, many, many, many, many, Many hundreds of years ago, plants in the Vervain family “decided” having a 5th stamen was unnecessary. “We can do just fine without it, thank you.” Thru the process of evolution, that expendable #5 was ever so slowly reduced to a tiny non-functional structure (referred to as a staminode in modern botanical lingo), or was completely and totally lost, becoming only a memory.

Believe me, this species is an energetic producer of leaves, flowers and seeds. In my experience, Davis Mountain Mock Vervain seems to explode in masses of pink and purple flowers throughout spring, summer and fall, and can last thru winters that don’t freeze. It’s easy to understand why the species has no need of a 5th fertile stamen. Once the plant becomes established, it keeps growing and flowering and spreading, often to the detriment of other desirable plants. If it wasn’t so gorgeous at the height of bloom, it might be considered a weed!

But I’m reminded of the definition of a “Weed ….. a plant out of place.” So yes, you’ll find me actively weeding actively growing Davis Mountain Mock Vervain so my other native plants have a chance at life too!!

Project Introduction

For the last few years my “someday” goal has been to create a nature field guide, of sorts, highlighting my many years of observations in the East Mountains of central New Mexico. Well, my “Someday” is officially here! Coinciding with the February 22, 2026 kick-off of the 100 Day Project¹ (Project), I began by committing an hour/day to developing that field guide as my project and immediately penciled out an outline and a few thumbnail sketches of a sample page. But, after retrieving my iNaturalist lists of East Mountains sightings I’ve made from home and during countless hikes, eliminating redundancies, and totaling up the individual species, my reported observations still numbered in the many hundreds. I would be working on this Project for the next five to six years!

Interlude

When we moved to the East Mountains in the summer of 2017, we quickly fell in love with the beauty of the wide open landscapes, the grasslands and woodlands habitats, the diverse populations of wildflowers and mammals, resident and migratory birds, and the insects and reptiles. So yes, nature is plentiful; species are many.

Now Back to the Project

Not to be overwhelmed (or defeated) by the potential magnitude of my Project, I decided to:

“Divide and Conquer” by focusing on a single location …. our current subdivision and surrounding area and trails; and
Prioritize quality over quantity by creating one page over two days, keeping each work session to one hour; and
Keep the Project motivating and interesting, by adding fun facts or other research tidbit about each species.

“These guidelines seemed more realistic,” I thought, with a cautiously optimistic chance of achieving my goal of creating a nature field guide.

So with that as an introduction to my Project, here’s Page 1 to “An Illustrated Guide to the Nature of Las Leyendas Subdivision & Environs, Tijeras, East Mountains, New Mexico” — with many more pages to follow. 🤞

¹ “The 100 Day Project is a free global art project that takes place online (https://www.the100dayproject.org/). Every year, thousands of people all around the world commit to 100 days of creating, and anyone can participate. The idea is simple: choose a creative project, do it every single day for 100 days, and document and share your process online. The most recent round of the Project began February 22, 2026, but any day is a great day to begin.”

Wait For It!

Spring is on the Way

February 10, 2026

One of my virtues is impatience ……. when it comes to Spring ….. and its arrival ….. finally.

Admittedly, winter has its perks. After a long, hot summer and fall, winter’s crisp air is a mood lifter, and cooler air temps allow for cozy sleeping under piles of blankets. Longer nights mean my favorite constellations hang in the sky longer, and somehow the moon always seems brighter and friendlier. In New Mexico, winter hiking about is more casual without having to watch every step for rattlesnakes, and certainly any snowfall we’ve been fortunate enough to get helps recharge water tables, tempers our risk of wildfire, and is absolutely beautiful to watch while falling.

But ….. since Winter Solstice and with daytime hours lengthening, I’m ready for Spring. And the closer it gets, my impatience for the upcoming change in season is obvious. My nature journal, pencils and 10x magnifying loop are packed and ready, each daily hike begins by plucking from a yucca one of last year’s flower stalks to poke the ground for signs of growth, and I’m anxious to snap photos of any passing migrating bird or resident roadrunner in search of a perfect nesting spot.

Meanwhile, I’m thankful for my late winter attack of impatience, because it get’s me out there every day, in anticipation of the first flower bud!

As always, Thanks for stopping by!

Switched the Midge!

A Fourwing Saltbush Gall Mystery Solved

September 30, 2025

If you’re a fan of weird twists in nature (like me), and enjoyed my November 25, 2024 post, “A Quirk of Nature: Fourwing Saltbush,” you may have lost many hours of sleep wondering how I could’ve missed such an obvious mistake! You know the one. The labeling error made when naming those cottonball-like insect galls hugging the Fourwing stems.

In my confusion (or wishing to cover all options?), I seemed to believe two different midge species were somehow responsible for the same gall.

Are they Rosette Bud Gall Midge galls or Fourwing Saltbush Wooly Gall Midge galls?

Decisions, decisions.

My Quandry quite clear, it was time to consult the experts.

A short 10 months later, confirmation arrived from the iNaturalist experts in all things “Fourwing.” All the puffy galls are none other than those made by Fourwing Saltbush Wooly Gall Midges!

And the answer to my question is well timed, as the stems of the female Fourwing shrubs are once again ‘heavy’ with Wooly Gall Midge galls. Now I know! Now you also know!

Enjoy this official correction, at long last, and wishing you sweet dreams.

As always, thanks for stopping by!

PS: My journal page was created by first sketching in graphite the two Fourwing stems, followed by outlining with loose ink lines from a Micron 005, adding a background of both soft and medium charcoal – blending with a stump, then using a Tombow Mono Zero eraser to clean up the ‘cottonballs,’ before adding watercolor pencil, color splatters, and eraser lines randomly placed through the charcoal background. A bit experimental, and lots of fun.

Floss is Flying 🪂 !

It Must be Fall …….

September 22, 2025

Like soft, fluffy snow! Glistening orbs of silky gossamer are floating about the neighborhood, drifting hither and yon in the gentle breeze. Suspended beneath each orb is a single reddish-brown winged seed that appears to coax its wind-propelled puff in a safe descent to the ground. But the white floss (the Coma) wants to fly, and it becomes a tug of war. As the weight of the seed overwhelms the ability (and the desire) of the floss to carry it, their brief relationship is severed. But both get their wish …. the floss flies free as the seed drops to the ground, hopefully landing in an ideal spot to overwinter and sprout next spring.

Welcome Fall!

When the air is full of Horsetail Milkweed parachutes and their ‘riders,’ I walk along the neighborhood roadways and collect a bounty of their new-crop seeds + floss to set free around our property. If they find the right soil, moisture, and light conditions for spring germination, the seeds will not only form the beginnings of a stand of these beautifully blooming, creamy-white milkweed flowers, but the plants might just play host to Monarch and Queen butterflies!

Now wouldn’t that be dandy!

(Of course, mature seeds from new plants will undoubtedly entice a hungry crop of well-dressed Milkweed Bugs next Fall. That’s OK! They have to eat too!)

My Journal Pages ……

For something different, instead of using ink and watercolor, all sketches on these pages were created in graphite. The pods, seeds and the milkweed bug were sketched from my collected samples using a mechanical pencil loaded with a fine point HB lead. The touches of color were added with water soluble graphite.

Thanks for stopping by ….. And Have a Fabulous Fall!

Shifts in Nature

August Littles ….. 2025

September 8, 2025

Ohhhhhh, what a sweet month …… August. It almost got away from me without sharing a small collection of Littles¹ that reflect the inevitable shifts in nature that occur during the month. It’s always hard to imagine summer winding down; where did the time go? But as surely as butter melts on freshly baked bread, undeniably, August forms a reliable bridge between summer and autumn. It’s a time of change and transition; abundance and harvest; transformation and a period of letting go.

So before I “let go” and before the snow flies (and it will), here’s a handful of little discoveries during the month of August:

-A female Wheel Bug gone slightly astray while searching for a protected place to overwinter the eggs she’s about to lay.

-A female Soldier Beetle doing her best to attract a mate by sending out pheromones while munching late season pollen from the disk flowers of a brilliant yellow Showy Goldeneye.

-An acorn that made it to maturity, ready to drop beneath a still green-leaved Gambel Oak soon to be decked out in radiant fall colors.

-Some hot red trumpet-shaped Scarlet Gilia flowers, still irresistible to hummingbirds until migration, will all be pollinated in time for seed set and mature.

-The snowy white fruit dangling from the draping branches of Roundleaf Snowberry shrubs are ripe and ready for plucking by hungry birds flying south for the winter.

-And plump purple-black Chokecherry berries that will become a juicy dietary supplement for black bears needing to bulk up for hibernation.

Enjoy!

And as always, thanks for dropping by!

¹“Littles” is part of a blog series I began posting several years ago, beginning in January 2023. The concept was inspired by Fay (thanks again Fay!) who came up with the idea for her blog madebyfay.wordpress.com

NATIONAL DIATOMACEOUS EARTH DAY

Part 1 – Diatomaceous Earth

August 31, 2025

On August 31, National Diatomaceous Earth Day recognizes the diatom and the remarkable mineral it creates!

Have you ever heard of Diatomaceous Earth (DE)? If you answer “yes” then perhaps you brew your own beer, have a swimming pool in need of water filtration, or a vegetable garden that’s been invaded by a herd of hungry slugs. But did you know DE is a mineral¹ composed of the fossilized remains of single-celled, microscopic algae called Diatoms? (More about diatoms in an upcoming post.) DE is truly a remarkable mineral, found around the world in ancient marine and lacustrine (freshwater lakes, streams, and rivers) sedimentary deposits.

Early Discoveries and Uses of DE

The year was 1836; the place, Northern Germany …… One day, a peasant named Peter Kasten was sinking a well when he encountered a mysterious-to-him layer of rock. Curious what this soft powdery rock might be, Pete took a sample to a friend who was a friend of a friend learned in the science of geology. This geologist carefully examined the rock then exclaimed (in German, of course), “Why this is the much prized and never-before-seen-in-Northern-Germany mineral known as Diatomaceous Earth! It has remarkably unique abilities to absorb, filtrate, polish, and stabilize! These qualities make Diatomaceous Earth (aka Diatomite) valuable and much sought after by numerous industries!”

Well, word spread and immediate exploration of the area commenced. It wasn’t long before numerous substantial deposits of lacustrine DE were discovered; some up to 92 feet thick! Extraction began in 1863. Until WWI, these sites comprised the world-wide production of Diatomite. Mining these deposits ended in 1994, when all of the DE deposits had been extracted.

But long before Pete’s discovery, Ancient Greeks used DE as an abrasive as well as a building material in lightweight bricks. Even in pre-historic times, DE was used in the ice-age cave paintings in France.

DE Deposits and Extraction – Worldwide

When diatoms die and fall to the bottom of marine and lacustrine waterbodies, they form large deposits. Over time, the organic portions of the diatoms weather away, leaving behind their hard silica shells. These remaining shells, called Frustules, with their opaline-like quality are what forms DE. Some of the largest deposits in the U.S. formed in ancient lakes that existed in California, Nevada, Oregon, and Washington. They also formed in oceans and occur along the coasts of North and South America.

Since WWI, exploration for and discovery of numerous DE deposits have occurred worldwide-wide, and are still on-going. Large mining companies have unearthed and continue to extract this mineral in substantial quantities, which is processed for use by industries that manufacture products for home and business (more on that below). DE deposits are (or have been) mined in many countries around the world, including the U.S., Mexico, Chile, Peru, France, Spain, Denmark, China, Canada, Argentina, Australia, Spain, Turkey, Libya, Russia, Mozambique, Ireland, and France. Today, the world’s largest DE mine, Colado Mine, is located just outside of Lovelock, NV, and has been in operation since 1959.

DE’s Modern Uses and Values

Today, DE is one of the most useful and durable substances known. The white to off-white powdery rock that makes up the more than 1 million year old DE deposits, is used in many common products likely encountered every day. One nearly universal use is in the filtration of liquids like the beer, wine and water. DE is also used to filter water in swimming pools, and to clean grease and oil. DE is used as an absorbent for hazmat spill control and in some kitty litters. As a filler in paint, it removes the sheen making flat paint flat; in plastics, it prevents blocking in plastic film. DE is used as an aggregate in construction, particularly in Portland Cement. And the list of specialty items that use DE for a variety of purposes is very long ….. including pharmaceuticals, cosmetics, art supplies, in the medical industry for DNA extraction, as a non-toxic insecticide, soil amendments, in bath mats for quick drying, in toothpaste as an abrasive, and as food additives to control moisture and extend shelf life. There are hundreds of other applications for DE with many more yet to be discovered!

But the biggest use of DE is in filtration. In 2023, the beverage industry paid $720/metric ton for processed food-grade DE (amount used to filter a keg of beer??). Compare that cost to $10/metric ton charged in 2023 for lightweight aggregates used in construction (wonder if or how tariffs impacted the 2025 cost?), or the $1000/metric ton charged for some specialty items.

Ideas on How to Observe Diatomaceous Earth Day

Discover more about DE, and learn about its common uses around your home or work.

Read product labels to learn what you use on a daily basis that contains DE.

Consult the fda.gov website to learn more about labeling.

Visit a Diatomite mining operation.

Learn about unmined deposits near where you live.

Use a magnifying glass or microscope to inspect the contents of bag of insecticidal DE.

Stay tuned for NATIONAL DIATOMACEOUS EARTH DAY – Part 2 – Diatoms! They are ultra-fascinating!

As always, thanks for stopping by!

¹ Minerals are naturally occurring, inorganic solids with a definite chemical composition and internal structure, and are the main components of rocks. DE (Diatomite) is a naturally occurring inorganic mineral that forms from the fossilized siliceous (silica-based) skeletons of diatoms, which are single-celled aquatic organisms. While the organisms themselves are organic, the hard, porous mineralized skeletons they produce are considered inorganic.

Being an inorganic mineral, DE falls into the same category as minerals we’re all familiar with, such as Quartz, Feldspar, Mica, Pyrite, Hematite, Galena, Sulfur, Gold, and Copper. The chemical formula of DE is primarily SiO₂ (silicon dioxide), with traces of other minerals.

One of the Most Aloof Sunflowers Ever! The Cowpen Daisy

Part 3 ….. An Allelopath Declares Chemical Warfare

August 15, 2025

The more I learn about Cowpen Daisy (Verbesina encelioides), the more the words Intrepid (fearless and bold), Interloping (meddlesome and smothering), and Impertinent (pushy and rude) come to mind.

Cowpen Daisy is literally a plant at war …..

Its adversaries are neighboring plants …..

Its weapons of choice are chemicals ….. 15¹different Allelochemicals² to be exact.

Cowpen Daisy shows no mercy to its most susceptible victims, and given the right conditions in the right locations, Cowpen Daisy can cripple ecosystems, and unravel biodiversity.

Oh No! What Have I Done! Have I unleashed a formidable enemy to run amok, bullying its way through our mostly intact biodiverse high desert ecosystem?

Maybe not! (Spoiler alert…… Allelopathy³can be bad, but I still love this happy Daisy)

On August 6th, I received an excellent question from one of my blog followers, based on my first Cowpen Daisy post :

“Do you have any concerns about this becoming an invasive plant? Best wishes, Nancy”

In reply, I expressed my concern about the number of “seedlings coming up late spring,” and how “I was definitely alarmed and wondered about the need for early control.” Fortunately, “as the season advanced, it became clear the density of plants seemed self-controlling.” Based on my limited experience with Cowpen Daisy, I explained how during the summer of 2023 “the plant completely covered an extremely large field near our home,” causing me concern about its invasive tendencies. But upon “[R]eturning the following year (2024) and again this past spring (2025) to see if the same field was blanketed again in these plants, “I couldn’t find a single Cowpen Daisy anywhere! So no, this annual [doesn’t appear to be] “invasive, at least not in central New Mexico.”

But Nancy’s question prompted me to dig deeper into on-line research. I wondered: Is Cowpen Daisy invasive outside of its native range, particularly where conditions are ideal for its aggressive growth? Yes, it is! And its invasiveness is further enhanced where neighboring plants are susceptible to the impacts of the allelochemicals released by Cowpen Daisy’s leaves, roots and decaying leaf matter in the soil.

One example where Cowpen Daisy is an introduced species and has become invasive is in India. Fields of mung bean, corn, chickpeas, and sweet melon are being outcompeted by invasive stands of Cowpen Daisies. These food crops are severely impacted by two allelochemicals released by the both roots and leaves of the Daisy; steroids and phenols. Studies of these four crops demonstrated not only “the suppression of germination and growth in these plants” but “also revealed an antagonistic effect on [their] chlorophylls, carotenoids and protein levels.” In other words, Cowpen Daisy is winning the war against India’s mung bean, corn, chickpea and melon crops, and farmers are currently engaged in a battle to develop a strategy of control and run this biological enemy out of their country.

Cowpen Daisy is only considered a native species to the Southwest U.S. and Northern Mexico. However, it has been introduced (either intentionally or by accident) and is considered naturalized in parts of Eastern North America, the Middle East, Spain, Argentina, Australia and the Pacific islands. As such, Cowpen Daisy’s nature to drop allelochemicals everywhere it grows allows it to behave like an invasive plant in countries where it is naturalized. Without diligent management (via herbicide application or mechanical control), it can thrive to the detriment of their desirable plant species’ survival.

Have I defeated my goal of reestablishing a diverse native plant community in disturbed areas surrounding our new home? “Not likely,” says I, optimistically! In addition to Cowpen Daisy, the variety of native plant species I intentionally seeded last fall and early this past spring, have germinated, grown, flowered and seeded or are in the process of flowering and seeding, most of which are adjacent to a Daisy. Of course time will tell. Meanwhile, I’ve declared this to be a happy ending to this post and my stand of happy Cowpen Daisies! However ……. next spring, if germination rates from my reseeders are low or zero, but Cowpen Daisy returns with renewed vigor, then I have a control job waiting for me. And the best advice I’ve read is to “pull out old plants and roots and selectively remove new seedlings.” That’s acceptable! That I can do!

Until then!

Do you struggle with weedy, invasive plant species in your garden or yard? Have you seen fields of blooming weeds and wondered …… “what weed is that?” Do you know the names of those pesty plants and do they seem to keep your favorite variety of cucumbers from growing? It might be interesting to learn if your local invasives are one of the many Allelopaths happily growing in our world! Let me know!

As always, thanks for dropping by!

¹Cowpen Daisy is known to release up to 15 different allelochemicals² from its leaves and roots, such as guanidine, phytosterols, phenolic acids, tripertenes, flavonoids, dicarboxylic acids, phytophenols, steroids, phenols, and others. Fresh and decaying leaf litter leach 14 of those allelochemicals into the soil.

^2,3Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms. These biochemicals are known as allelochemicals and can have beneficial (positive allelopathy) or detrimental (negative allelopathy) effects on the target organisms and the community. Allelopathy is often used narrowly to describe chemically-mediated competition between plants. Allelopathic interactions are an important factor in determining species distribution and abundance within plant communities, and are also thought to be important in the success of many invasive plants.

One of the Most Edible Sunflowers Ever! The Cowpen Daisy

Part 2 ….. Ethnobotany, Etymology and Epicureans

August 11, 2025

While compiling last week’s post about the happy Cowpen Daisy party taking place outside our back door, it was no surprise to find way more interesting info about this sunflower than could ever fit on my journal page. Decisions …… decisions! To keep the August 5th illustrated page relatively uncluttered, I decided to include just the botanical basics (mostly), focusing on Cowpen Daisy flowers, leaves and seeds.

Then the past week I found my nature journal wide open to a blank page, ‘begging me’ for another Cowpen Daisy entry ….. “What about all those interesting info bits?” she asked. Replying* to my journal with a hearty, “OK,” I proceeded to locate and gather my rabbit-trailing notes. This scavenger hunt reminded me just how many pages there were; so many fascinating things about the Cowpen Daisy I wanted to remember and share. Decisions …… decisions! How to keep this next post to one page? By limiting the topics to only three, was it possible?

Barely! (after some clever editing, not a single word dropped off the page)

A little bit closer view for those without a microscope!

P.S. By the way, you may have noticed I’ve indicated this post is Part 2 of what’s now become my Cowpen Daisy series. Unless I start journaling on larger than 8” x 11” paper, there’s likely to be more Parts in store. And this multi-part series resulted in a minor edit to last week’s post, not titled “One of the Happiest Sunflowers Ever! The Cowpen Daisy; Part 1 ….. Can There Be Too Many Sunflowers?” In case you missed it, please check it out here.

*Yes, you read that right; I talk with my nature journals. Don’t you? After all, we do spend quite a bit of time together!

As always, thanks for stopping by!
