Hooked on Trichomes … The Curious Nature of ‘Mentzelia’

July 29, 2025

You must awake when the first rooster crows to enjoy the floral beauty of a fully flaired Blazingstar blossom. Appropriately named, these gorgeous flowers display a radiant combination of spoon-shaped petals, petal-like stamens, and hundreds of thread-like stamens, all colored in bold sulfur yellows, distinctive pale orange-yellows, brilliant star whites, or fluorescent blues, based on species. These superbly showy flowers unfurl overnight atop tall white, branching stems that resemble candelabras with narrow lobed green leaves. These large, 2” diameter flowers belong to the Mentzelia genus, plants that are all native to the Americas, and represented by 60-80 species, most found in the desert southwest.

In 1753, Carl Linneaus gave this plant its genus name, Mentzelia, after German botanist and sinologist Christian Mentzel. (Did you know a Sinologist is a specialist in the study of Chinese language, literature, and civilization? Huh!) But perhaps more fascinating and what’s always ‘captured’ my complete attention (and blue jeans) is that the Mentzelia genus fits perfectly in the Loasaceae family ….. commonly referred to as the Stickleafs.

About those leaves ……

Being primarily a day-time hiker, my first encounter with a Blazingstar occurred simultaneously with a misstep into the plant. Noticing some resistance in making my escape, I looked down at the ground and discovered my jeans had a collection of stuck leaves from my boots on up. And the leaves were really stuck tight along their entire length! Removing those leaves was like peeling a banana, only tougher. Wait! Forget the banana peel. Removing those sticky leaves sounded like and felt like tugging on and separating Velcro! I was reminded of the familiar ‘ripping’ noise made when Velcro hooks are forcibly released from their loops!

Eureka!!

Nature is full of surprises. Were the Stickleafs the source of accidental inspiration for today’s handy hook-n-loop fastener, called Velcro? Almost, but not quite! As it turns out, the tiny hooks on Cocklebur seedpods inspired a Swiss engineer to develop Velcro in 1941. But not to change subjects too much …….The reasons Stickleafs could’ve been the inspiration for Velcro, is similar to the Cocklebur story, but, I think, even better. Here’s why ……

The seedpods of both plants have tiny hooks that readily adhere to clothing and fur. And it was the hooks’ tenacity for stick-to-it-tiv-ness that grew the original Velcro idea. But Stickleafs go even further in ‘reinforcing’ the fastener concept. Not only does the seed pod (capsule) of Stickleafs have a covering of tiny hooks, but both leaf surfaces and even the stems of plants in this family can have multiple types of minuscule grappling-hooks and barbed needles, called Trichomes, visible only with an electron microscope. I summarize that if the Swiss engineer was visiting America in 1941, and had the good fortune to walk into a Mentzelia plant, he undoubtedly would’ve been super inspired to develop Velcro. After all, it’s the leaves that stick fast to clothing, resemble a strip of Velcro, and hold tight, mimicking an ideal hook-n-loop fastener.

Hooked on Trichomes

And now for the curious nature of the Mentzelia genus. When coming across the Adonis Blazingstar (Mentzelia multiflora) over the past 8 years, it’s been fun to inspect the leaves, remove one and intentionally stick it to Roy’s jeans or mine. I’ve then wondered how this plant ‘sticks’ so well, and why. The time for answers arrived this month, and what I learned was fascinating. It’s all about Trichomes.

Trichome is a botanical term used to describe the small hair-like structures that occur somewhere on a plant; typically on plant leaves. Trichomes can be found throughout the plant kingdom (like on Cannabis sativa); they aren’t unique to the Stickleaf family, and are found on all species of the the Mentzelia genus. Some Mentzelia species have one type or shape of trichome; some have several types. Adonis Blazingstar has two types of trichomes – one is shaped like a grappling hook; one is shaped like a barbed needle. It’s the trichomes that grab on and hold tight. But what possible function do they serve the plant? Surely a leaf sticking to the fur of a passing animal or a person’s pant leg, while decorative, is otherwise pointless?

What Good are Mentzelia Trichomes?

Like plant hairs, trichomes aid a plant in water conservation in times of drought by reducing transpiration, and in situations of other environmental stressors, such as excessive UV light and extreme temperatures. The trichomes serve as a protective barrier between the leaf, stem, or other part of the plant, and the environment.

Trichomes can function as water collection, retention and funneling structures during a rainstorm.

The grab-and-hold nature of trichomes when they attach to fur or clothing can cause enough vibration of mature seed capsules to shake loose seeds ready for dispersal.

Trichomes are the plant’s primary defense against herbivory; not from livestock or rodents intent on munching leaves, but from insects that attempt crawling amongst the grappling hooks and barbed needles intent on causing damage. As can be seen in electron microscope images, insects have been photographed speared and hooked and killed because they were unable to escape their entrapment by trichomes.

But not all insects succumb to the fate of trichomes. Aphids are able to navigate the dense forest of hooks and needles without capture, allowing them to wreak havoc on vulnerable and tasty leaves, stems and seed capsules.

And that’s why the Mentzelia genus of the Stickleaf family is one of the natural curiosities of the plant kingdom. Maybe now, you too, are Hooked on Trichomes?

I hope you’ve enjoyed this post, and do thank you for stopping by!

And if you’re curious about how Trichomes contribute to the enjoyment and/or medicinal benefits of marijuana (Cannabis sativa), here’s what I found:

Trichomes are the primary site for cannabinoid production (i.e. compounds like THC & CBD responsible for the plant’s psychoactive/therapeutic effects.

Trichomes are the site of terpene production which gives different Cannabis strains their unique aromas/flavors.

Trichomes are the site of flavonoids known for antioxidant and medicinal properties.

Red Barberry – An Unforgettable Encounter

July 23, 2025

When you think of ‘Barberry,’ does a shrubby knee-high landscaping bush that transforms to flame red in the fall, come to mind? If so, you may have seen hedge rows of the plant known as Japanese barberry ……

Japanese barberry (Berberis thunbergii) is a non-native shrub that was introduced from Japan in 1875 as an ornamental that’s planted for erosion control and as a living fence. But this invasive shrub outcompetes and displaces native plants, alters ecosystems, and is a host species of black-legged ticks that carry Lyme disease.

When you think of ‘Holly,’ does a plant with boughs of prickly green leathery leaves naturally ‘decorated’ for the holidays with red berries, come to mind? If so, you’re likely familiar with the iconic American holly ……

American holly (Ilex opaca) is a native shrub of eastern and south-central U.S. that grows well in both dry and swampy soils. The plant, which is also cultivated as an ornamental, forms thick a canopy cover for birds and other wildlife, and the female plants produce an abundance of shocking red berries, loved by birds but poisonous to dogs, cats and humans. Regardless of the risk, bountiful quantities of leafy boughs and clusters of red berries are harvested each fall and brought indoors to create holiday wreaths and other seasonal decorations.

Now imagine you’re hiking in a pinyon-juniper forest of the American Southwest. You decide to bushwhack to a connecting trail and all of a sudden find yourself hopelessly stuck in a 10 foot high shrub covered in juicy red berries and very prickly holly-like leaves. This large (somewhat familiar) shrub is a surprisingly effective barricade; a formidable fence. You’ve become entangled in thousands of armed leaves preventing your forward or backwards movement without getting seriously poked and stabbed!

Is this the desert variety of American holly? Maybe it’s the giant living fence of a Japanese barberry gone rogue?

Nope! It’s neither. You’ve stumbled upon (into) a hardy specimen of the desert Southwest native Red Barberry (Berberis haematocarpa). But no wonder you were confused. This shrub, which can grow to 13 feet tall and nearly as wide, has an abundance of holly-shaped leaflets armed by a sharp spine on each lobe tip. And if birds haven’t devoured all of the red berries, you may find an ample supply of a refreshing (albeit tart) snack while you carefully and oh-so-slowly free yourself from the shrub’s embrace.

Red Barberry leaves – each lobe tip is armed with a needle-like spine

By now you’ve created lasting memories of Red Barberry, and have promised to always be alert for surprise encounters when visiting the desert island Southwest.

The hiking scenario above conjured up one of my hard-learned lessons from 8 years ago. Having just moved to New Mexico, Roy & I began avidly hiking local trails. Wishing to master the native flora as quickly as possible, one day I discovered clusters of red berries hanging inside the leafy canopy of a 5 foot shrub. What could they be?! Only having eyes for those juicy berries and an irresistible urge to gather a bunch for closer inspection, I plunged my open hand through several layers of small leaflets and successfully clutched a cluster. It was then I realized those spiny leaflets had poked, scratched and even penetrated my bare skin, as evidenced by tiny trickles of blood dripping from my hand and arm! Now that I had captured those pretty berries, it was obvious they had to be released to permit me the delicate maneuvers required to free my arm and minimize further injury. It was that day that I learned all about Red Barberry; lessons that will likely stick with me always!

Since that close encounter 8 years ago, it’s no surprise I’ve never been a big Red Barberry fan, until ……

…… this past May a 13 foot tall plant in front of our home burst out in the most spectacular display of sunshine yellow flowers, literally covering the entire shrub front to back; top to bottom! The fragrance was overwhelming for the entire 2+ weeks the flowers were in bloom. And not only our Barberry was in full bloom, but about a dozen more barberries in our neighborhood and surrounding area were also covered in vibrant yellow. It was an amazing sight, causing me to figuratively re-embrace the native Red Barberry!

For more tidbits about Red Barberry, browse the text and illustrations displayed on my journal pages. Hope you enjoyed this post.

As always, thanks for stopping by!

P.S. In case you’d like to know about the etymology of the name Berberis haematocarpa…… ‘Berberis’ is a Latinized form of the Arabian name ‘barbaris, for barberry. “Haematocarpa” means ‘blood-red fruit’ referring to the bright red berries produced by this shrub. The word is derived from the Greek words “haima” (blood) and “karpos” (fruit).

It’s National Lollipop Day! 🍭

Lollipop Lollipop – oh-lolli-Lollipop! 🎶

Today, Flambé was craving a generous dollop of whimsy and an extreme sugar rush to feed her ever insatiable sweet tooth. Today, she insisted on choosing the National celebratory day that would simultaneously satisfy both her exorbitant desires. Today, Kat took a calculated leap, gracefully “sticking” her landing on one of those oversized spirals of sweet colors-on-a-stick. Today, Flambé picked National Lollipop Day!

While Kat is frantically licking her paws to break free of that giant Lollipop, my task was to learn stuff about those ultra-sweet confections.

Lollipops have been around for how long? Apparently no one is really sure how old the ‘lollipop’ is, but it’s likely this treat on a stick has been around for centuries. There’s even speculation that during prehistoric times, a form of ‘lollipop’ may have preserved nuts and berries in honey. Then as sugar became commonplace, lollys “popped” up as a popular treat in 16th century Europe. In the 17th century, the English enjoyed boiled sugar candy treats on sticks, which made the candies easier to eat. And in the mid-19th century (1860s), confectionaries and medicine shops in the U.S sold ‘lollipops’ in various forms.

The Name Lollipop ….. may have been used for centuries. A word sounding much like ‘lollipop’ was heard in Europe as early as the 4th century. Nomadic Roma people (also called Gypsies) migrating throughout Europe, had a tradition of selling candy apples on a stick. Red apple in the Romani language is loli phaba. In the late 18th century (1796), English lexicographer¹ Francis Grose recorded the term ‘lollipop’ that was likely derived by combining the words ‘lolly’ (which means tongue) and ‘pop’ (which means slap, describing the slapping or popping sound one made when sucking on hard candy). But it wasn’t until 1908, when Mr. George Smith, an American candy store owner and inventor from New Haven, Connecticut, developed a machine that could produce large quantities of hard candies mounted on sticks. Thinking about what to call those popular treats, he finally decided on Lollipop, the name of his favorite racehorse “Lolly Pops.” Smith trademarked the lollipop name in 1931.

Today, the modern Lollipop comes in a variety of sizes, shapes, colors (usually brightly colored), and flavors (usually fruit flavored). Some have fillings, like bubblegum, soft candy (think Tootsie Pops), soft chocolate, jawbreakers, and fizzy candy. Some are even medicinal (where medicines for weight loss and cancer treatments are added to the candy). And then there’s the novelty lollipops! Some contain unusual items like a mealworm larvae, scorpion, cricket, or ants, suspended in the clear-as-glass candy, so you can see the bugs while sucking on the lollipop! Some novelty lollipops have non-edible centers, like a flashing light, a small toy, or even a motorized device attached to the stick that makes the candy spin around in your mouth!

Lollipop Pop Culture – By now you’re probably humming one of Shirley Temple’s favorite tunes, “On the Good Ship Lollipop.” Maybe you’re thinking about “The Lollipop Guild” gleefully welcoming Dorothy to the Land of Oz. Did you ever (or maybe you still do) count the number of licks it takes to reach the center of a Tootsie Pop? I always questioned whether Kojak (you know, the TV series from the 70s) actually became more of a tough guy while sucking a lollipop. Hmmmmm?

Celebrate National Lollipop Day – The phrase of the day must be Lollipop Fun! You’re never too old to enjoy a brightly-colored, spirally-twisted lollipop. Buy a bagful of Tootsie Pops or Dum-Dums and share them with your family, friends, and neighbors. Visit a local candy-making factory and watch how they make these sweet treats on a stick. Try out one of the unique novelty lollipops, if you dare. Write a short story or a poem about lollipops and illustrate it in a kaleidoscope of colors. To me, lollipops remind me of riding a carousel pony, possibly named “Lolly Pops,” while at the carnival.

Now that Flambé has freed her paws from that giant spiral-shaped lollipop, she’s busy licking her way to the soft tuna center. That should keep her out of mischief for the rest of the day! Meanwhile, please let us know what your Lollipop Fun plans are for the day. Maybe share your favorite lollipop shape, color, and flavor guaranteed to put a big smile on your face!

¹A lexicographer is a person who compiles dictionaries. You know …. of ‘Webster’s Dictionary’ fame, Noah Webster (October 16, 1758 – May 28, 1843) was an American lexicographer, textbook pioneer, English-language spelling reformer, political writer, editor, and author. He has been called the “Father of American Scholarship and Education”.

National Simplicity Day

July 12, 2025

Henry David Thoreau (July 12, 1817 – May 6, 1862), believed a life of simplicity could lead to greater happiness and a deeper connection with ourselves and the surrounding world. An American naturalist, essayist, author, poet and philosopher, Thoreau advocated a life free of unnecessary complexities; free of details. He declared “our life is frittered away by detail. Simplify, simplify!”

And Thoreau wasn’t just talking about material possessions. He also promoted reducing mental clutter, focusing on what truly matters, and living in harmony with nature. Thoreau so strongly advocated for Simplicity, he chose to live several years in a cabin he built in the woods at Walden Pond near Concord, Massachusetts. Writing about the experience in his well known book “Walden,” was a reflection of his dedication to live simply and be self-sufficient while being surrounded by nature.

Thoreau’s famous quote, “Simplicity, Simplicity, Simplicity!” sums up his philosophy perfectly.

Today is a celebration of Thoreau’s philosophical approach to a life well lived.

Instead of spending hours drawing and coloring complex, ultra-detailed Zentangle art, I chose eight botanical patterns to recreate as stand-alone illustrations. Because of my insatiable need for details, this was challenging. But it was also very satisfying!

How might you choose to Simplify your life, if even for a day?

Mexican Hat

July 11, 2025

A few years ago I stumbled across this plant while walking around our neighborhood. Being immediately awed by its richly-colored petals skirting an upright cylinder or cone, I knew it would be a perfect addition to our high elevation (7,300 feet) landscape. My idea was to wait until the flowers on the cone faded and collect some seed to scatter in our yard. After repeated trips hoping to find evidence of seed, I was skunked. Either I missed the dispersal event, or this plant was 100% sterile. On the outside chance there were microscopic seeds embedded in the cone, I resorted to cone collection. Fast forward to the next spring …… every spot I’d planted those cones was barren; nothing had sprouted; zero; zip.

Fast forward again to early July 2025. This wildly blooming plant was growing vigorously in many of the dry disturbed openings and roadside areas throughout our new neighborhood! Time to learn more about such a charming member of the sunflower family called Mexican Hat.

Mexican Hat (Ratibida columnifera), also commonly known as rocketflower, and both upright and longhead prairie coneflower, is a native perennial found across the Lower “48” (U.S.), southern Canada and northern Mexico at elevations ranging from 5,000-7,500 feet. Its Ray flowers come in a dazzling sunshine yellow, along with a soft velvety royal purple-brown, an intensely deep rust-red brown, and rusty oranges – all with some measure of sunshine yellow marginal accents. Each Disc flower (those tiny spots that spiral, Fibonacci fashion, around the upright cone) has 5 fused pale-green petals (the Corolla). The Corolla surrounds 5 fused purple/red oxide-colored Anthers (the pollen structures of the Stamens). The Anthers are shoved up through the Corolla by the developing Style (the stalk of the Pistil) where they burst into 5 sunshine yellow pollen “strands” resembling a hairdo of long, twisted, windblown dreadlocks! The shockingly beautiful colors unfailingly lure many insects hungry for pollen and/or nectar.

The entire Capitulum (the densely packed flowerhead of a composite “flower”) continually waves in the slightest of breezes as it perches atop the long stiff and naked stem (the Peduncle) of the flowerhead. Below the Peduncle are the many branched feathery-like, deeply lobed leaves. These leaves seem to be the primary source of a curiously fascinating fragrance. After handling the plants for several days, I began thinking of the aroma as being cautiously sweet-scented with subtle hints of slow roasted tomato + red pepper-infused homemade shortbread cookies! I’m looking for a recipe!

All “said and done,” Mexican Hat can grow from 8 inches tall to over 3 feet!

Benefits of and Curiosities About Mexican Hat

Special Value to Native Bees – According to The Xerces Society for Invertebrate Conservation, Mexican Hat is recognized by pollination ecologists as attracting large numbers of native bees.

Food Source for Wildlife Species – In addition to being an important source of pollen and nectar for native bees, Mexican Hat also attracts many other insects like butterflies and moths, and hummingbirds sip its sweet nectar. Wildlife that feast on its seeds include small song birds, wild turkey and rodents. Even white-tailed deer will eat the foliage, despite its reported deer-resistant qualities.

Supports Native Pollinators, Attracts Beneficial Insects, and Promotes Biological Diversity – Mexican Hat is a adaptable and resilient wildflower species, able to endure extended periods of drought, hot and cold temperatures, and diverse habitat and soil conditions. Because of these characteristics, and because the species is a self-seeder, Mexican Hat provides food and cover for wildlife, is a reliable source of pollen for at-risk native bees, and makes an excellent choice for sustainable gardening, habitat and soil restoration, and prairie conservation efforts. And not to be overlooked, Mexican Hat attracts beneficial insects like lady beetles and lacewings that help control garden pests like aphids and caterpillars, and makes a valuable contribution to natural pest management strategies.

Many Uses; the Ethnobotany of Mexican Hat – North American indigenous peoples prepared the leaves, stems, flowers and/or the cones in certain ways to treat specific ailments suffered by people and animals. By creating washes, by boiling, physically rubbing and crushing, decoctions, concoctions and infusions were used to treat chest pains, wounds, stomach aches, fevers, headaches, urinary problems, rattlesnake bites and to induce vomiting. Mothers wishing to wean their babies had crushed leaves rubbed on their breasts. Horses with urinary problems were hand fed the entire plant as a cure, and sheep that are “out of their minds” are given a cold infusion.

The cones were used as baby nipples. Leaves and flowerheads were boiled to make a pleasant tasting tea.

A Symbolic Meaning and Familiar Visual of Mexican Hat – In Mexican culture, this wildflower is often associated with traditional celebrations, ceremonies and festivals. Mexican Hat is a symbol of joy, abundance and cultural heritage. The common name “Mexican Hat” was given to this wildflower because it reminds many of the shape of a traditional Mexican sombrero.

Origin of the Scientific Name Ratibida columnifera – The Etymology of the genus name Ratibida was published in 1818 by Constantine Samuel Rafinesque-Schmaltz (1783–1840). Even to this day, the meaning of Ratibida is a mystery. It’s well known that Rafinesque-Schmaltz often assigned unexplained names to plants. Oh, and be aware that around 60 sites online use the spelling “Ratidiba” rather than Ratibida. So if poking around the internet for more information about Mexican Hat or any of the other prairie coneflowers, don’t be fooled by the typo!

The species epithet columnifera is a Latin name meaning “bearing columns.” This refers the tall cylindrical or cone-shaped flowerhead (Capitulum) which is the support structure (the Receptacle) for the numerous Disc flowers, the 7 Ray flowers, and the 7 small leafy bracts (Phyllaries).

Loving My Mexican Hat!

Early this spring I purchased 2 Mexican Hat plants for our garden. I’m happy to report they are doing great and loaded with 10-20 yet-to-mature pale green cones. Wonder what color the Ray petals will be?

I’m also planning to collect seed again this year, after learning the best time is early Fall when the cones look like they’re withering. Wish me luck!

Hope you enjoyed my exploration of this marvelous native perennial member of the sunflower family. Even though in a previous post I made a thorough plunge into the sunflower family, I learned even more putting this post together.
