Finding the Picabo Milkvetch—A Rare Idaho Endemic
By Samuel DeGrey, Loasa Chapter President
When driving along US-Highway 26 between
Shoshone and Carey, very few are aware that this
route passes through the middle of the range of
one of Idaho’s rarest plant species. The Picabo
milkvetch (Astragalus oniciformis Barneby) is
only found on sandy soils in parts of Lincoln,
Minidoka, and Blaine counties in south-central
Idaho, and nowhere else. Named for the small
town of Picabo (pronounced “pikaboo”), this plant
is listed as occurring “in the foothills of the Saw-
tooth mountains and adjacent Snake River Plain”
in A Flora of the Pacific Northwest. Most popula-
tions occur in relatively flat lava-desert, well away
from the margins of the mountains, nowhere near
what we typically call the Sawtooths. (We may as-
sume that the Sawtooths actually refer to the Pio-
neer Mountains, which include the Sawtooths.)
Given the specific soil requirements of the plant,
its effective distribution is even smaller than its al-
ready small range would indicate. The species is
thought to be declining throughout its range.
I had been interested in the milkvetch since
moving to the Magic Valley area. I decided to orga-
nize an INPS outing to try to see the rare plant
while it was in bloom. We, of the Loasa Chapter,
joined forces with the Wood River Chapter, a per-
fect collaboration given the milkvetch’s range
straddles the border of our two regions. Meeting
up in the town of Picabo, we caravaned to an ob-
scure patch of BLM land sandwiched between
ranches and agricultural fields. Rolling down a
bumpy rocky road, we set out on a long drive to a
known locality for the milkvetch.
As we continued down the two-track, we began
to notice the soil becoming increasingly sandy, al-
most sand-dune or beach-like, but well-covered
with vegetation. Eventually we reached the loca-
tion of our first known population. We hopped out
of the car and fanned out in search of the milk -
vetch. The area was well choked out with inva-
sives, especially pepperweeds, and signs of trample
by livestock and other ungulates abounded. We
hardly saw any blooming plants, and no milk -
vetches of any kind—unusual given the Picabo
desert area typically abounds with many species.
Demoralized, I was about ready to call everyone to
head out to the next spot, when suddenly I noticed
something. It was a tiny, greyish-green compound
leaf poking out from under some grass. I stooped
down to look. Could it be? There was indeed a
small milkvetch poking its way through the weeds.
The Picabo milkvetch can be distinguished
from other milkvetches in the immediate Picabo
desert area by the combination of the following
characteristics: relatively small size, greyish-green
leaflets that tend to be folded over the midline,
the jointed apical leaflet (which distinguishes it

Idaho’s native flora contains somewhere in the neighborhood of 2800
vascular plant species. Everything from minute aquatic species such as wa-
ter-meal and duckweed that may be only 0.04 inch or so in size, to giant
western red cedars in northern Idaho that can exceed 170 feet in height. An
assortment of environmental conditions and associated habitats contribute
to Idaho’s diverse flora, including an elevation gradient spanning nearly
12,000 feet from the summit of Mount Borah to the mouth of the Clearwater
River at Lewiston, geology that varies from ancient marine sediments to re-
cent lava deposits, and annual precipitation that ranges from approximately
7 inches/year at Grand View to 40 inches at Wallace. It should therefore not
be a surprise there is no shortage of great places to enjoy Idaho’s wildflower
diversity. In the early spring, Hells Canyon is tough to beat. The Owyhee
high desert can be a rainbow of colors later in the spring; as can hidden
washes and basins in the Challis country, or the lava landscape of Craters of
the Moon. Late spring is also a choice time for the Basin and Range valleys in
east-central Idaho. Early summer provides wildflowers galore in the Clear-
water and other north Idaho forests. High mountains defining the central
part of the state all the way to the Panhandle wait until mid-summer before
reaching full glory. Mountain meadows, deep forests, juniper woodlands,
canyon grasslands, sagebrush plains, peatlands–Idaho has them all.
Idaho Native Plant Society members are especially appreciative of the
state’s floristic richness. The Society’s mission entails sharing this apprecia-
tion and in doing so increasing the population of people who understand the
values of native plants and are willing to promote their conservation. As an
all-volunteer organization, INPS depends on its membership to meet this
mission. Volunteer opportunities abound, whether it is assisting on a native
plant habitat restoration project or other chapter-sponsored events such as a
native plant sale, or having a native plant information table at a community
event. A new volunteer opportunity is outlined in this newsletter (see page
4). I would greatly appreciate it if an INPS member could help with this In-
formation Technology (IT) need. More fully utilizing CIVICRM (software
used by INPS) capabilities will improve the efficiency of routine tasks needed
to run our organization and allow better communication to the membership,
among other things. I am also looking for one or two volunteers to be part of
the INPS Scholarship Committee. Main responsibilities will include getting
the word out about the scholarship program to all Idaho colleges and univer-
sities and reviewing scholarship applications. Please contact me if you are in-
terested in assisting with either of these needs (president@
idahonativeplants.org).
As always, if you have any questions or concerns about INPS, please
reach out to me.
Enjoy the summer season.

Sage Notes Vol. 46 (2) June 2024
from another local endemic—Astragalus atratus var. in
septus, the Fairfield milkvetch), free stipules, basifixed
pubescence, and the small,
cream-colored flowers. After
running through these charac-
teristics, I declared that we had
found the Picabo milkvetch!
However, I was dismayed, as
we were only able to find a cou-
ple in a tiny area. Was this
milkvetch population becoming
extirpated already?
We headed back to the two-
track, spirits higher, and de-
cided to head down to the next locality. Before we could
hop back in our cars, someone yelled out “I found
one...and another!” We all stopped and began searching
around; soon we were picking out milkvetches every-
where! They were so small and inconspicuous, we had
walked right past them. We quickly found around 20
milkvetches by the two-track, where they seemed to be
more abundant. Heading down the road, we bumped and
ground through sand and lava until we found the next site
—adjacent to a watering hole surrounded by a large herd
of cattle giving us the evil eye. Surely there would be none
in this heavily disturbed site?
Over 100 Picabo milkvetch sightings later, we were
quickly proven wrong. They seemed to be thriving
around the cattle wallow, and once again seemed to be
more abundant near the road. Upland lava ridges yielded
little to no milkvetches. Once again, no other species of
Astragalus were seen—except one possible sighting of a
woollypod milkvetch (Astragalus purshii), normally
ubiquitous across southern Idaho. Satisfied, our party set
back down the road, on the way home. My car was the
last in line and I was surprised to see Wood River Chap-
ter members standing around the fence which led out of
the BLM land. I hopped out and as it turns out they had
counted over 100 Picabo milkvetch, right there at the en-
trance from the main road! Once again, the bizarre little
plant seemed to be thriving in a highly disturbed spot,
which we had originally passed right over.
If Picabo milkvetch thrives with so much with distur-
bance, then why is it rare and declining? There are a vari-
ety of possible reasons. Some of the milkvetch’s polli -
nators may also be rare and possibly declining, for one.
We should not take the plant’s continued existence for
granted, even if it appears to be locally thriving.
The Picabo milkvetch is not alone—its closest relative
is also a rare, threatened, Snake River Plain endemic.
Mulford’s milkvetch (Astragalus mulfordiae) is endemic
to the Owyhee Front, Treasure Valley, and Weiser areas
in southwestern Idaho and adjacent eastern Oregon, and
is similar in habitat and appearance to Picabo milkvetch.
The two species can be distinguished by generally upright
stems and connate stipules for Mulford's milkvetch, com-
pared to more prostrate stems and free stipules for
Picabo milkvetch. More easily though, the two can be dis-
tinguished by the fact that they have no known range
overlap.
Thank you to the Wood River Chapter for joining us
on the trip, and to Samantha Seabrook-Sturgis for pro-
viding helpful advice about the Picabo milkvetch.

You are invited to participate in the Intermountain
Botanical Foray! The Foray is an annual event organized
by the Intermountain Herbarium at Utah State Univer-
sity and regional partners. Each year botanists of all
stripes spend a long weekend at a different botanical
hotspot in the Intermountain Region to intensively col-
lect and identify plants, document biodiversity, and gen-
erally nerd out in all manners plant-related.
Foray 2024 is co-hosted by Snow College, and will take
place from July 11–July 15 at the Great Basin Station in
Ephraim, Utah! Thank you to our partners at Snow Col-
lege and the Forest Service for helping make this possible,
and for the support of the Utah Native Plant Society.
The historic Great Basin Station is located in Ephraim
Canyon in the Wasatch Plateau area of the Manti-La Sal
National Forest. We are looking forward to exploring the
aspen-conifer forests and subalpine meadows of this area
—it will be a stark contrast to last year’s high desert
ecosystem! We hope to see some neat endemics such as
Astragalus montii and Eriogonum brevicaule var. caeli
tum (pictured).
The Great Basin Station has a kitchen, bunks, and a
classroom gathering area. Participants will be responsible
for bringing their own bedding and food, while the orga-
nizers will take care of permitting and providing collect-
ing supplies and instruction. Thursday and Monday will
primarily be travel days. On Friday, Saturday, and Sun-
day we will survey different areas of botanical interest,
and each evening we will spend time identifying and
pressing our specimens, intermixed with some botanical
and cultural presentations. This will be a wonderful op-
portunity for those interested in botany to learn from ex-
perts and each other, as well as to explore this interesting
locality.
We would love for you to join us! You can sign up to
attend the Foray at https://forms.gle/jEHgB8Kpi2KD-
j1oc6. Please email [email protected] with any ques-
tions or to get on the email list for next year. And please
spread the word to interested friends/colleagues!
Happy botanizing!

INPS Scholarship
The INPS Scholarship Committee has selected this
year’s two $2,000 awardees, one graduate student and
one undergraduate student. Congratulations to Erika
Stewart and Elizabeth Mandala! There were 26 applicants
this year, including 7 graduate students, and 19 under-
graduate students. Each applicant received a free 1-year
membership in INPS. This is the second year we have
granted scholarships. As members of the committee, Liz
Martin (chair), Penny Morgan, Paul Ries, and Bill
Bridges, we are pleased that the outreach about the schol-
arships helps people across Idaho learn more about INPS.
Erika Stewart
Erika is a PhD student at Idaho State University
(ISU). She says her interest in native plants started in
second grade when she remembered learning about milk-
weed and its relationship with monarch butterflies. Her
interest continued to grow in high school as she collected
sagebrush seed with BLM for fire restoration and she
planted willow, dogwood and other riparian plants with
Idaho Department of Fish and Game. After high school,
Erika received her bachelor’s degree in environmental
science at the University of Idaho. Her senior thesis fo-
cused on using native plants on campus. After gradua-
tion, she spent several years working as a field technician
and crew lead doing rare plant surveys, riparian restora-
tion work, and fire recovery monitoring. She never had a
botany course, so she had to teach herself how to key
plants and identify them.
After several years as a field technician, Erika’s love of
plants led her to graduate school. As a PhD student, she
is doing research for the Idaho Transportation Depart-
ment to identify roadside restoration methods that si-
mul taneously reduce weed invasion and fire hazard while
enhancing pollinator diversity, habitat, and abundance.
Erika’s advisor describes her as a leader, mentor, and
advocate for both undergraduate and graduate students.
She currently volunteers as President of Idaho State Uni-
versity’s Biology Graduate Student Association and re-
cently served as the graduate representative on the ISU
Biology Department’s Tenure and Promotion Committee.
She also volunteers hosting summer camps for kids.
Elizabeth Mandala
Elizabeth is in her senior year studying biology, ecol-
ogy and conservation at Idaho State University (ISU).
She says, “Since taking my first plant identification class
at Idaho State University in 2021, I have been hooked like
a cocklebur on a thick woolen sock.” She joined the Idaho
Native Plant Society in 2022 and keys plants in the Ray J.
Davis Herbarium every Friday. Motivated by a desire to
engage students and community members with activities
cultivating plant appreciation she founded the ISU
Botany Club and currently serves as its president. The
club is now an official student chapter of the Botanical
Society of America. Elizabeth is also vice chair of the
High Desert Chapter of Idaho Master Naturalists. Her
advisor describes her as a leader and says as a non-tradi-
tional student she provides a mature, calming, and com-
petent presence for other students.
Since returning to college in 2021, Elizabeth has
worked as a research assistant helping several different
graduate students with their master’s projects. Following
graduation, she will continue research from her senior
thesis that she expects will culminate in writing a flora of
southeastern Idaho for her master’s thesis. She intends to
use her scholarship award to enroll this summer in ISU’s
Field Botany course to provide a better foundation for
her to contribute to the Idaho Botanical Foray that will be
hosted by ISU in June.
Please encourage students you know to apply next
year. For more information, including the criteria used to
select the best candidates, please visit the INPS website

scholarship program in 2023, and for funding two
awards and the INPS membership given to all the stu-
dents who applied each year. We also thank all the appli-
cants and those who wrote recommendation letters for
them—we welcome you all to be active in INPS.

Local Partnership Helps Move Rare Aquatic Plant Toward Recovery
By Brenda Erhardt, Latah Soil and Water Conservation District, White Pine Chapter
Rare Plant Spotlight
Back in 2011, landowners Leona and Jason Svancara
recognized the presence of water howellia (Howellia
aquatilis) on their property in Princeton, Idahoand re-
quested the assistance of agency
partners to learn more about
this unassuming aquatic plant.
The unique plant also turned
out to be really rare. Water
howellia also occurs in Califor-
nia, Washington, Oregon, and
Montana.
Water howellia was listed as
Threatened under the Endan-
gered Species Act in 1994 be-
cause of threats from timber
harvest, weed encroachment,
development, and grazing. Because of this listing, part-
ners have been working throughout the species’ range to
reduce the threats. Water howellia was delisted in 2021
following recovery progress, but the status change did
not stop these dedicated land stewards from continuing
to work to protect this unusual and rare plant.
Idaho has approximately six known water howellia
populations (Lichthardt and Pekas 2019), one of which
occurs in Princeton, Idaho, in oxbow ponds in the flood-
plain of the Palouse River. Even though water howellia
was delisted, threats to Idaho’s small number of popula-
tions are ongoing. One significant threat to water how-
ellia habitat, including the Princeton location, is
encroachment by invasive weeds such as reed canary-
grass (Phalaris arundinacea).
Partners work together to restore rare plants
The landowners teamed up with the Idaho Natural
Heritage Program (INHP) and U.S Fish and Wildlife Ser-
vice (USFWS) in 2012 in support of water howellia moni-
toring on seven ponds within their property (Figure 1). In
2020, USFWS coordinated with the Latah Soil and Water
Conservation District (Latah SWCD) to continue INHP’s
past water howellia monitoring on the Princeton site
(Element Occurrence (EO) 4) and nearby Harvard site
(EO 1) (Figure 2). (An EO is an area of land in which a
species or natural community is or was present.) Water
howellia and reed canarygrass frequency and water depth
data were collected at these sites for a decade by partners.
The newest data are currently being analyzed but old re-
ports are available (see Lichthardt and Pekas 2019).
Restoration experimentation in action
During the 2023 monitoring event, the landowners
expressed their ideas for reed canarygrass control to offer
protection for the future of their water howellia popula-
tion. This included plans to experiment with the removal
of reed canarygrass surrounding one pond (Pond 2) using
multiple strategies (mechanical and chemical) followed
by re-planting of the area with native grasses, sedges,
trees, and shrubs. Restoration work in 2023 included the
following:
Reed canarygrass control
(Funded and completed by landowners)
1. Reed canarygrass thatch removal on the east end of
Pond 2 followed by minor regrading of this disturbed
area to enhance future pond inundation (Figure 3).
2. Grass selective herbicide treatments to suppress re-
sprouting reed canarygrass following thatch removal.
3. Annual early to mid-summer mowing around pond
edges and in fields surrounding the ponds paired with
additional chemical, mechanical (disc and harrow), and
re-seeding treatments to prevent re-encroachment of
reed canarygrass.
Restoration plantings
(Funded by USFWS and INPS; completed by INPS vol
unteers and Latah SWCD staff and field crew)
4. Fall shrub and sedge plantings in the Pond 2 reed
canarygrass control zone (Figures 3-7, Table 1).
5. Seeding with native grass mix throughout the dis-
turbed area (Figure 8, seed tag photo).
It takes a village
While this effort has just begun, the partnership be-
tween the landowners, Latah SWCD, USFWS, and INPS
has been steadfast in its support of the restoration work,
and everyone involved continues to contribute to the
project financially and in-kind. Ongoing work will in-
clude monitoring the initial reed canarygrass control ef-
forts and the subsequent restoration plantings to inform
future needs at this site. Additional control work, re-
seeding, and plantings will be adapted to the conditions
and will continue as needed. Lessons learned from the
Pond 2 work may be utilized to expand the reed canary-
grass reduction efforts at this and other pond locations if
found to be effective and feasible.

Desert Moss Ecology and Identification
By Roger Rosentreter, Pahove Chapter
Plant Identication
Desert mosses often lack enough moisture where they
grow to sexually reproduce, making them quite a chal-
lenge to identify. A ten-power hand lens helps, but the
absence of reproductive structures complicates the iden-
tification greatly. For this reason, I have created a com-
parison table (Table 1) that focuses on vegetative
characteristics to identify some of the most common taxa
found in the western US.
How do these dry land mosses multiply if they rarely
produce reproductive structures? Both the red roof and
silver-tipped moss reproduce vegetatively–their leaf tips
simply break-off, initiating a new colony. Silver-tipped
moss is especially common on sidewalks around the
world. Even though sidewalks are harsh sites on which to
establish and grow, these “tough guy” mosses take advan-
tage of such extreme habitats.
Twisted moss, another remarkable species commonly
found in our region, consiste mostly of female “plants”
(14:1 ratio, according to Stark et al. 1998). Twisted moss
also reproduces asexually (vegetatively), with any part of
the plant capable of regenerating, either directly or via an
initial protonema (Mishler 1988). Protonema are an early
stage or growth form of mosses that appear as green
threads, more characteristic of algae. The key is rapid
asexual establishment during the short periods favorable
for growth. This adaptation facilitates growth and estab-
lishment in a water-limited environment.
These tiny, non-vascular spore-bearing land plants
are extremely important in deserts, sagebrush steppe,
alpine, and many other habitats around the globe. In
spite of their prevalence, many researchers have
“biocrust blindness” and never even see these minute
ecosystem engineers. Mosses are excellent soil stabilizers
(Copeland et al. 2023) by collecting blowing dust, adding
soil depth and nutrients. They also reduce water and
wind erosion (Eldridge and Leys 2003). Mosses inhibit
large invasive annual grass seeds from becoming estab-
lished by physically perching the seed above the soil sur-
face (Serpe et al. 2006). The seeds may germinate, but
the root radical cannot reach the soil before the seed
dries out (Serpe et al. 2008). Mosses can decrease fire in-
tensity or act as natural fuel breaks in sagebrush steppe
habitats (Condon et al. 2023). They act much like a gar-
dener’s mulch, increasing water infiltration and decreas-
ing soil moisture evaporation.

Family Spotlight
Rays and Disks—The Asteraceae Family in Idaho
By Don Essig, Wes Essig (Data Compilation), Pahove Chapter
You know this family as daisies, sunflowers, and dan-
delions. This is one of the largest plant families in the
world, accounting for about 10% of all known species and
is especially dominant in temperate climates like ours. In
Idaho there are 120 genera and 450 species of asters. The
Erigeron genus is the most diverse with 45 species, while
52 genera are mono-typic in Idaho. In this family, what we
think of as one flower is actually a composite of many
small flowers or florets bunched together on a common re-
ceptacle forming a flower head, aka inflorescence. Indeed,
before standardization in taxonomic naming, this was
known as the Compositae family. Below is a list of aster
family species, née composites, of Idaho.
Four types of florets are found—ray, disk, ligulate and
bilabiate. All four consist of five fused petals. Ray florets
are straplike flattened tubes that are sterile or may contain
only female reproductive parts—pistils. These florets are
what we pull out of a daisy as we wonder if “he/she loves
me—he/she loves me not”. What remains when we are
done wondering is a cluster of tubular disk florets that
make up the center of a daisy. Ligulate florets are like rays
but have five teeth and are perfect, that is, contain both
male (anthers) and female (pistil) parts. Relatively rare bi-
labiate florets have a longer lower lip.
Most aster inflorescences, like those of daisies and sun-
flowers, have both peripheral ray and central disk florets.
Other genera have only disk florets, like Chaenactis, this-
tles, and western coneflower. Plants in the cichorioideae
subtribe—characterized by chicory but including dande-
lions—have only ligulate florets. Some members of the
aster family have multiple inflorescences on a branched
flower stalk. You will never confuse a hawksbeard (Crepis
sp.) with a dandelion (Taraxacum sp.) if you remember
the former has a branched flower stalk while the latter has
one flower head per stalk.
In Idaho, one of the most iconic members of this
widely distributed family is arrowleaf balsamroot. Sage-
brush and rabbitbrush are also widespread and well-
known members of this family even if not often recognized
as asters. Most aster family species are, however, non-
woody perennials with rather showy flower heads. Many
asters are summer or fall bloomers, brightening our land-
scape well after spring blooms are gone. Some of our worst
weeds are asters as well, e.g. knapweed and star thistle.
Next time you are out in the sagebrush steppe, look
around—the closest flower you see is most likely a member
of the aster family.

The Pahove Chapter has been offering a series of wild-
flower/natural history walks this spring, thus far led by
local botanist Barbara Ertter. Walks are selected to show-
case the diversity of habitats and particularly interesting
species in the greater Boise Front (as per https://boise-
frontnature.com/), preferentially using old roadbeds
(better for groups) instead of single-track trails. Specific
walks are decided upon about a week in advance, based
on a combination of current phenology and weather re-
ports (and the walk leader’s schedule!). Notifications of
each walk are then circulated by email to Pahove mem-
bers. Dogs are not encouraged, due to general incompati-
bilities between generic dog-walking and focused
wildflower walks. For a selection of self-guided walk op-
tions, check out https://boisefrontnature.com/wild-
flower-walks/.
Lydle Gulch, 10 April 2024
One of the earliest wildflower walks was to Lydle
Gulch in the Lucky Peak Dam Recreation Area, where we
w able to catch two locally rare plants in bloom: hare's-
foot milkvetch (Astragalus purshii var. lagopinus) and
Beckwith's violet (Viola beckwithii). The unusual vol-
canic soils provide one of the only localities for hare's-
foot milkvetch in
Idaho, which differs
from the much more
common variety of
woolly-pod milkvetch
(A. purshii var. glare
ous) in its more com-
pact growth form,
smaller flowers, and
smaller fruit. Parti -ci -
pants were also treated to a prime remnant of good-qual-
ity sagebrush steppe with a fine selection of early spring
flowers, along with an overview of the unusual geology of
the area and natural history observations by Mary Hal-
lock Foote. Although not part of the walk, participants
were encouraged to visit the Foote Interpretive Site at the
mouth of Lydle Gulch, to learn more about Mary and her
husband Arthur, and to admire the wildflower garden
created and maintained by INPS volunteers.
Oregon Trail Recreation Area, 30 April 2024
The stretch of the Oregon Trail above basalt cliffs on
the south side of the Boise River lies in the Intermoun-
tain Flora, with some different flowers than can be found
in the foothills north of the river (in the Flora of the Pa
cific Northwest). Participants in the photo are standing
behind a patch of hairy balsamroot (Balsamorhiza
hispidula, or B. hookeri var. hispidula). The larger plant
in the lower right corner is a hybrid between hairy bal-
samroot and arrowleaf balsamroot; heads are drooping
because of the previous night's freezing temperatures.
Some other plants of local interest included bigseed bis-
cuitroot (Lomatium macrocarpum) and a form of wax
currant (Ribes cereum) growing on the basalt rimrock;
Oregon cliff fern (Woodsia oregana) was another treat to
admire. General discussion wandered from intact vs. in-
vaded sagebrush steppe to plants-as-geologists to Arthur
and Mary Hallock Foote and the construction of Diver-
sion Dam, complete with excerpts from Mary Hallock
Foote's book "The Chosen Valley."
Three Bears Trail, 16 May 2024
The next wildflower walk was along the lower end of
Three Bears Trail at the east end of Fort Boise-Military
Reserve in the central Foothills, where we enjoyed a nice
selection of flowers growing on a diversity of geological
substrates, with volcanic layers cutting through Lake

Pahove Chapter's Earth Day Celebration
By Vicki Henderson, Pahove Chapter, Open AI, 2024
In May, the Pahove Chapter participated in Boise’s
Earth Day Celebration at Kristin Armstrong Municipal
Park, which attracted hundreds of visitors. The Idaho
Native Plant Society (INPS) participated by handing out
information on membership, upcoming events including
the plant sale and the Mother’s Day Wildflower+ Show,
and the importance of native plants.
This year's theme, "Climate Action," emphasized sim-
ple steps to combat climate change. Community partners
provided ideas for creating personal climate action plans,
rewarding participants with thank you gifts. The celebra-
tion highlighted Boise's commitment to sustainability,
with attendees encouraged to walk, ride, or roll to the
event. The high turnout and enthusiastic response under-
scored the community's dedication to environmental
stewardship.
Idaho sediments.
Highlights included a
lovely stand of
longspur or “poly-
chrome” lupine (Lupi
nus arbustus), the
locally rare Bolander's
yampah (Perideridia
bolanderi) on the vol-
canics, Lindley’s sil-
verpuffs (Uropappus
lindleyi), and the bizarre Franciscan broomrape (Aphyl
lon franciscanum, previously included in Orobanche fas
ciculatum) growing as a root parasite on silverleaf
phacelia (Phacelia hastata).
Mores Creek High Bridge, 5 June 2024
The most recent wildflower walk allowed us to marvel
at a wonderful diversity of local plants on a surprisingly
intact north-facing slope overlooking the High Bridge
over Mores Creek Arm
of Lucky Peak Reser-
voir. After a minimally
interesting uphill slog
through a previous
burn area now domi-
nated by non-natives,
we were rewarded with
a gentle transect across
a north-facing slope
harboring amazingly in-
tact shrub-steppe on
the edge of the Idaho
Batholith. The beautiful wildflower-covered slope in-
cluded numerous species not found on the Lake Idaho
sediments of the central foothills. Among the special

Chapter Activities
The Pahove Chapter is celebrating the success of its 6th
Annual Wildflower+ Show, in near-perfect weather at the
Idaho Botanical Garden on Mother’s Day, May 12, 2024.
Several hundred people were able to enjoy and learn about
over 200 different wild-collected plants, attractively ar-
ranged and labeled with both common and scientific
names in a pleasant outdoor setting. Plants had been gath-
ered for several days from in and around Boise, across the
Snake River in the Owyhees, and as far afield as Hells
Canyon, by Barbara Ertter, Beth Corbin, Don Mansfield,
Bob Moseley, Martha McClay, and Jessica Irwin.
Early on the morning of the show, a dedicated cadre
of botanists, Master Naturalists, and other volunteers
converged on the shaded plaza of the Idaho Botanical
Garden to arrange tables, vases, flowers, and labels in
what, at times, seemed organized chaos but which ulti-
mately resulted in an amazingly fast and efficient set-up,
ready to be admired by Mother’s Day visitors to the Gar-
den. Volunteers reconverged at the end of the show,
quickly clearing the tables, repacking vases in newspaper,
and schlepping boxes back to cars.
As in previous years, plants were arranged by several
categories: native wildflowers (the largest category this
year), herbaceous non-natives,
woody plants, grasses and
grasslike plants, and ferns and
relatives. Several of us stayed
throughout the show, answering
questions and encouraging in-
terest among visitors. Young vis-
itors in particular really enjoyed
the magnifying glasses scattered
around, allowing a closer look at
fascinating details of the plants.
In the shade of a separate
large tent-canopy, several tables
provided information on spe-
cialty topics. In addition to the
Pahove table itself, superbly
staffed by Kevin Laughlin, vis-
itors flocked to tables to learn
about native plant activities at
the Garden (including propa-
gation of the rare Boise sand-
verbena), bees and the Master
Mellitologist program, and liv-
erworts (with special thanks
to Daniel Murphy, Amy
Dolan, and Chadwick DeFehr).
We hope to have more spe-
cialty topic tables at future
shows, with lots of
ideas already in the
hopper!
Special thanks
to the Idaho Botan-
ical Garden for con-
tinuing to host the
annual Wild-
flower+ Show, and
in particular to
Visitor Services/
Event Coordinator
Hannah Cain and
her team in getting
everything set up as
needed; to the ama -
zing volunteers
from the Sage-
Brush Steppe and
Deer Flat Chapters
of Idaho Master
Naturalists, in par-
ticular Helen Harrington for
taking on the coordinator role
so capably; to those especially
dedicated volunteers who
stayed the entire day; and to
Susan Ziebarth for creating
the poster and getting new
labels laminated.

Pahove Chapter's Annual Native Plant Sale
By Bethany Tennant, Biological Aide, MK Nature Center; Photos by Lynn Kinter
This year’s native plant sale was the first that I’ve at-
tended since I began working at MK Nature Center as a
Biological Aide in 2023. Even before the doors opened for
the sale, the energy was palpable as I watched the line of
waiting customers stretch into the parking lot, so far that
I couldn’t see where it ended.
Before my time at MK Nature Center I had worked
many years in retail, and I knew immediately that the
turnout for this sale was to rival most Black Friday events
I’d seen in the past. It was amazing to see just how many
members of the community arrived early to wait in long
lines for the chance to purchase native plants. I lay in
wait at a register, and once the doors opened, eager cus-
tomers trickled in and eventually made their way to
where I was. It became clear that people were not just
buying plants—they were engaging in conversations
about sustainability, pollinator support, and the impor-
tance of preserving local biodiversity. I saw how this
event fostered a genuine connection between attendees
and the natural world, leaving so many attendees in-
spired to cultivate their own small patches of paradise.
Overall, the native plant sale felt like more than just a
shopping experience; it felt like a celebration of nature
and community. It was a joy to spend time with the nu-
merous volunteers who worked so hard to bring this
event together, and it was truly inspiring to see just how
many community members were invested in supporting
our native plants.

the Center. The plant
sale was held in

time since 2019.

What do you think of when you hear "Craters of the Moon National Monument?"
Maybe a hot, rocky landscape. A gray, empty, volcanic area where nothing grows and
plants can't survive. Well, it turns out a lot of plants can survive in this desert in
Eastern Idaho, and Dr. Lynn Kinter knows firsthand. She's been studying plants for
more than 35 years. Dr. Kinter is an adjunct graduate faculty member in the
Department of Biological Sciences at
Boise State University, and she talked
about the Flora of the Craters of the
Moon on Monday, March 25, at the
Osher Lifelong Learning Institute. She
joined Idaho Matters for a preview.
