White Milkwort – Page 11 .. The 100 Day Project (2026)

June 1, 2026

White Milkwort (Senega alba (Nutt.) J.F.B. Pastore & J.R. Abbott)

(synonymous with Polygala alba Nutt.)

A Light Touch

It was a beautiful morning for a walk along one of the neighborhood’s 2-track dirt roads. I was searching for late blooming Spring wildflowers when something lightly brushed against my leg, bringing me to a full stop. There, at my feet, gently swaying in the quiet breeze were a dozen+ foot tall, nearly naked, skinny green stems topped with lavender and white cones. Not wishing to crush these delicate stalks, I noticed there were five other groupings nearby, all growing in the road’s old tire depressions. Upon closer inspection, I recalled having seen this plant before in the yard of our previous home, but they had fewer and shorter stems, and larger (?) flower cones. Still, this was the white milkwort species (back then known as Polygala alba; today called Senega alba) I identified four years ago. It was the larger size and delicate nature of these plants at my feet – that puzzled me.

Here’s what I learned:

The stems, which are ridged, can grow to 18” tall. They branch from a basal caudex (a root-like thickened stem, often found underground, from which branching/stems grow …… and the more extensive the caudex, the more above ground stems form.
You can roughly age this perennial milkwort by counting the number of vertical stems. Typically there’s one stem on seedlings and one-year old plants; as many as 30 stems have been counted on much older (many, many years old) plants.
Even though the official flowering period ends late summer, if mid-summer/early fall rains (our monsoon season) are plentiful, another bloom period peaks and can continue into November. It’s been reported that when old flowers are removed from these milkworts (deadheaded), the plants will bloom continuously for up to four years! Obviously, those plants are not impacted by winter frosts.
The 90% of the pollinators visiting white milkwort are small to medium solitary or semi-solitary bees. Where we live (desert southwest), many of these ground-nesting bees are floral specialists, and based on research dating back to the early 70s, green metallic bees highly favor this native plant’s flowers for nectar and pollen. And with extended bloom times prompted by monsoons, this helps benefit these and other bee species. Unfortunately, the timing and intensity of our monsoons is no longer predictable and is likely causing unfavorable conditions for extended flower bloom and the bees.
Always be prepared to encounter a plant that tickles!

Classification and an Etymological Quandary

To learn the story about the old and new scientific names for white milkwort, and why being a botanist way back when and today is so challenging, read the next section on Etymology. It really is quite fascinating!

Etymology

Way back in the day (say, the early 1800s), when Thomas Nuttall, a English botanist, ornithologist, geologist and explorer, needed an unforgettably descriptive binomial name for a new species he’d discovered, “Polygala alba Nutt.” was his choice. The genus “Polygala,” which was originally assigned by Linnaeus to a group of plants with similar-looking flowers, is Greek for milkwort — meaning “much milk; ” the species name “alba” is Latin for “white, bright or clear.”

Thomas, logically picked “alba” as the species name for his new discovery, because the plant had white flowers. However, he apparently chose the “Polygala” genus based on an ancient belief that nursing mothers (and cows) that ate the milkwort plant experienced increased lactation. However, Polygala alba doesn’t have either milky sap or any plant parts with milk! After diving deeper into the Polygala genus as a whole, I couldn’t find any that ooze a milky substance.

The changing nature of botanical classification: It wasn’t until recently (2023 to be exact) that the official report announcing the transfer of 18 Polygala species to Senega, including Polygala alba to Senega alba, was published by botanists J.F.B. Pastore & J.R. Abbott. This change was based on a number of scientifically-researched plant characteristics, which addressed deviations in seed, fruit, and floral anatomy between Senega and true Polygala species. Now I know I need a bigger microscope!

In case you’re curious (I certainly was) there are no Senega milkworts (today referred to as American milkworts, formerly classified under Polygala) with a milky sap. So, despite their family (Polygalaceae) and originally assigned genus name (Polygala), these plants exude a clear, watery sap when their stems are broken.

Why “Senega” was selected as the genus name for all American milkworts: The genus name “Senega” comes from the Seneca Native American tribe. The first use of the name in the English language was in the 1730s; the Seneca snakeroot plant was given the scientific name Polygala senega, to honor the tribe’s traditional use of the root as a remedy for snakebites and respiratory issues.

Narrowleaf Puccoon – Page 10 .. The 100 Day Project (2026)

May 25, 2026

Narrowleaf Puccoon (Lithospermum incisum)

Etymology

Lithospermum, the genus named by Linnaeus in 1753, is Greek for stone (“Lithos”) and seed (“sperma”), referring to the hard nutlets. And “incisum,” the Latin species name referring to the incised, fringed edges of the trumpet flowers, was named by Lehman (a German botanist) in 1818 from a specimen collected “near the rapids of the Ohio” by Andre Michaux (a French botanist and explorer) in 1802.

Puccoon evolved from “poughkone,” a word the Virginia Algonquian language used for plants whose roots yield a red or yellow pigment. The roots of Narrowleaf Puccoon were historically used as dyes ranging from purple to red to yellow.

A Two-Flower Strategy

Very showy and quite lovely, the sunshine yellow trumpet-shaped flowers of Narrowleaf Puccoon are hard to miss. They often cluster at the ends of 12-20” long stems where the floral tube is ringed by five frilly petal lobes. The flowers depend on pollinators like butterflies for cross-pollination which adds genetic diversity to the few seeds they produce. Botanically speaking, these traditional, open flowers with exposed reproductive parts are referred to as Chasmogamous.

Then later in the season, the Narrowleaf Puccoon produces small, petal-less flowers that remain tightly closed. These highly fertile, self-pollinating flowers account for almost all of the plant’s seed production. Botanists refer to this type of closed, often inconspicuous flower as Cleistogamous.

The“Stone Seed” Fruit

Because Narrowleaf Puccoon only produces the occasional fruit from its showy flowers, it takes a bit of searching around the plant’s lower leaf axils to locate a tiny group of up to four hard “stone seed” nutlets. Beginning growth inside the self-fertile, closed (Cleistogamous) flowers that are present late in the season, each egg-shaped nutlet, pitted across the surface, ripens to a shiny white.

Plant Propagation

Seed Germination – To grow Narrowleaf Puccoon from seed, nutlets should be collected in late summer. Soak them overnight in hot water then plant immediately. Because seed germination is sporadic and often disappointing, selecting a desirable location for planting is important. The plant grows best in very sandy, well drained soils found in the dry/open areas within our pinyon/juniper woodlands (though they do grow in soils with some loam or clay).

Root Cutting – A more successful method may be to take a 2-inch cutting of the taproot in the fall. Dip the cutting in a root stimulant and plant in a desirable location.

Suggestions for root stimulants

Powdered Hormones: Highly cost-effective, have a long shelf life and easy to use. After you moisten the root cutting, just dip it directly into the powder (e.g., Garden Safe TakeRoot) and plant.
Natural/DIY Options: Raw aloe vera gel and crushed, uncoated aspirin both contain natural growth-promoting enzymes. You can also use diluted willow bark extract, which is naturally rich in rooting hormones.

Plant Care – Narrowleaf Puccoon requires full sun and very little water, making it a good plant for xeric gardens or included with other native plants to establish a wildflower meadow.

Medicinal Properties and a Cautionary Note

The Navajo chewed the root of Narrowleaf Puccoon for coughs and colds. They, and the Zuni rubbed the plant’s finely powdered leaves, root and stem on the body to treat paralyzed limbs. An infusion of the root was used for stomach aches and kidney problems. The plant was eaten as an oral contraceptive, and a cold infusion of the pulverized root and seed was used as an eyewash.

Although Narrowleaf Puccoon does have medicinal properties, it contains potentially toxic alkaloids. Self-treatment involving this plant is strongly discouraged.

…………………………………………………………………………………………………

If you’ve seen Narrowleaf Puccoon, did you find their highly fertile, tightly closed flowers and/or the shiny white nutlets? Have you tried growing the plant from seed or root cuttings, and were you successful?

As always, thanks for stopping by!

Happy Memorial Day!

Rose Heath – Page 9 .. The 100 Day Project (2026)

May 9, 2026

Rose Heath (Chaetopappa ericoides)

When the last Spring snow melts and the runoff soaks into the nooks and crannies of dehydrated soils, there’s a thirsty little shrub that eagerly drinks its fill. The leafy stems of this tiny shrub, so easily overlooked in the winter, rapidly grows on bare ground, around the drip line of pinyon and juniper trees, in the negative spaces between rocks and broken branches, and through beds of dried grasses. Then in a day or two a very small flower bud forms on the top of each stem, and in half a week the buds open simultaneously. What a spectacular display of brilliant white daisies ….. bouquets of light!

Barely ankle high, each flowerhead can have up to 24 white ray florets surrounding a rich buttery yellow center of 12-25 disc florets. And don’t fret if you notice the ray florets have curled downward in the evening. They magically unfurl to their full length by mid-morning the following day.

This annual Spring show, which takes place all across the U.S. west and western Great Plains, is brought to you by the “petite” perennial called Rose Heath (Chaetopappa eriocoides). (Widespread and common in New Mexico, Rose Heath is adaptable to a variety of soils, elevation, and drought.)

The show typically begins in late March and continues into early May. And for those craving more, flowering resumes in August and can run until November; no charge. You just have to get out there and see for yourself!

Origin and Etymology – What’s in a Name?

Origin of the Scientific Name, Chaetopappa ericoides

Augustin Pyramus de Candolle, a Swiss botanist, named this genus Inula in the early 1800s. But in 1827, it was the American botanist John Torrey, who named the species Inula ericoides, from a specimen collected by botanist Edwin James along the Canadian River during Major Stephen Long’s Expedition of 1819-1820. Since that time, the species has undergone more than a dozen name changes including Leucelene ericoides (Edward Greene in 1896) and finally Chaetopappa ericoides (Guy Nesom in 1988).

Etymology of the Scientific Name, Chaetopappa ericoides

The genus “Chaetopappa” is Greek for ‘bristly pappus’ (pappus refers to the score of tiny white bristles surrounding the disc florets; the same bristles, one per seed, that helps carry Rose Heath’s mature seeds up, up and away. The species “Ericoides,” also Greek, means ‘similar (“oides“) to Heath’ (“eric”); i.e., the plant’s tiny, overlapping leaves are similar to those of some Heaths (Ericaceae is the scientific name of the Heath Family.)

Common Name, Rose Heath

From the previous paragraph, it’s obvious where the name ‘Heath’ comes from, as Rose Heath does have stems and leaves very similar to a heath plant. But why ‘Rose?’ What I found is ‘Rose’ is Latin in origin, derived from “rosa,” referring to the flower. Because the daisy-like flowers of Rose Heath don’t resemble a rose flower, deeper diving was needed. I discovered that throughout history ‘Rosa’ and ‘Rose’ have represented love, passion, innocence, and beauty. So perhaps ……. ? If you’re familiar with Rose Heath or have seen photos of the plant in bloom, do you love or could you love its beautiful floral bouquets? I think whoever thought to call this plant by the common name ‘Rose Heath,’ must’ve loved its stunning display!

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!

Late Bloomers …. Fall’s Flowery Foothills

September 26 & 27, 2023

It’s hard now to imagine how extremely hot and dry the summer was this year. Without even a spittle of rain, the 100+ degree temps for weeks effectively suppressed the usual mid-season bloomers in and around the Albuquerque foothills/East Mountains. Even invasive plants, like goathead and tumbleweed, remained dormant or failed to germinate all together. It looked like winter browns had arrived early.

Then in less than a week, a small rain followed by several long downpours flooded the parched landscape, transforming browns to greens. You’ve heard this from me in a few earlier posts, but it was magical, and a reminder about the resiliency of desert vegetation.

Here’s a few pages highlighting a handful of the Late Bloomers I recorded in only 2 days. More than 2 dozen species had sprung back to life, setting flowers at all stages of accelerated vegetative growth. The landscape seemed wide awake. If plants could talk, I imagined them laughing while excitedly chanting, “hurry, hurry, hurry!” Only their roots prevented them from dancing!

In addition to the species on these journal pages, there are many (more) composites, native grasses, shrubs and sub shrubs, small forbs from Spring and early Summer actively growing and blooming right now, and (of course) the weedy invasives are growing and blooming with wild abandon.

Random thoughts and wonderings ….. are pollinators still hanging around …… or ….. how many of today’s bloomers are self fertile …… are local birds, insects, reptiles and mammals that depend on earlier summer pollen and/or fruit and seed production stressed with this timing change/availability of food sources … will there be noticeable shifts in species composition, including plants, insects, reptiles and animals (including birds) ….. what species can and will adapt to changes, and how quickly ….. etc. The answers to these and many more questions are probably best answered in coming years, if it’s even possible to answer them at all.

Have you observed vegetation anomalies that may be influenced by changes in climate? If so, please share your observations and where these changes are taking place. Meanwhile, keep your eyes wide open.

Intermission: Meet an Odd Member of the Rose Family …. The Desert (Eastern) Mountain Mahogany

February 8, 2023

The Desert (Eastern) Mountain Mahogany is a very branchy shrub commonly found in the mid-elevation foothills of the Sandia, Manzanita, and Manzano Mountains east of the Rio Grande River in central New Mexico. This species’ formal and very appropriate name, Cercocarpus breviflorus variety breviflorus, comes from both Greek (kerkos: tail; karpos: fruit) and Latin (brevi: short; florus: flowered). As a matter of fact, the 9 species of the genus Cercocarpus all have long feathery tails that twist and turn from the tip of a single fruit, called an achene (like a sunflower seed).

So why is this species odd?

Well, the fruit, for one reason. Most of the thousands of rose family members have fruits called a hip (rose), pome (apple), drupe (prune), or aggregate (strawberry). And even though the strawberry is composed of numerous miniature achenes, it’s the single achene found in the mountain mahoganies that’s unusual to the family.

To further emphasize the oddness of the Cercocarpus genera, all of its 9 species has a symbiotic relationship with a bacteria called Frankia. And that’s an unusual characteristic of the rose family, which moved Cercocarpus and 4 other genera into the subfamily Dryadoideae. That’s all a bit technical when it comes to plant classification, and kind of skips the real reason why the Frankia bacteria is important to the survival of Desert Mountain Mahogany. Nitrogen Fixation!
