Number of Ramblers today: 33

Today’s Emphasis: medicinal and culinary uses of plants. (We discussed traditional uses of plants but do not advise or recommend the use of any particular plants for culinary or medicinal use. This discussion is presented for educational purposes only and should not be considered as a recommendation or an endorsement of any particular medical or health treatment. Consult a health care provider before pursuing any medical treatment.)

Announcements:
Catherine Chastain, a long-time rambler, is teaching a “Printing With Botanicals” class on Thursday, June 13, 6:00 – 8:30 pm at the Garden. You will learn to create lovely results with leaves, flowers, and even vegetables using inks, watercolors, and solar paper. Printing is a great way to see nature’s beauty up close in a new way. Wear an apron or clothes suitable for creative, messy endeavors. No artistic experience is required, just a spirit of play and wonder! Call to register: 706-542-6156. OR to register online, click here.

Nature Rambler rainy day policy: we show up at 9:00am, rain or shine. If it’s raining, we will meet and socialize in the conservatory (bring your own coffee); if a break in the rain opens up, we’ll go out and do a little rambling.

Heather thanked everyone for the card we sent her following her recent surgery. We are so glad to welcome Heather back!

Bob announced that he will give a reading from his new book, Between Birdsong and Boulder: Poems on the Life of Gaia, at Avid Bookshop on June 11, 7:00-8:00pm. The set of poems will be “Creation, Destruction, and Recreation – Poems on the Resiliency of Gaia.” Amy Rosemond will be the respondent / conversation partner.

Susie Criswell announced that she has an exhibit of her paintings in the Earth Fare dining area (turn left as soon as you enter the store). The exhibit will be up till the end of June.

“Milkweed” by Susie Criswell

Today’s Reading: Liana read “Crows in the Wind,” a poem by A. E. Stallings, who graduated from the University of Georgia and is currently Professor of Poetry at Oxford University. For more on her career and studies click here.

Crows in the Wind
Hooded Crow: Corvus cornix

On windy days the crows cavort
Down slides of air for autumn sport.
They dive and spiral, twirl and spin,
Then levitate to ride again.

That wind that makes their airy slide
Comes tumbling down the mountainside,
Tousles the heads of trees and drops
To the sea beyond the cypress tops,

And drinking at the sea’s blue lips
Makes paper sailboats out of ships,
Whose distant swiftness seems repose
Compared to capers of the crows.

Their calligraphic loops concur
In copperplate of signature,
Or in formation they prepare,
Drilling at dogfights with thin air.

Watching them, I want to say
They are intelligence at play
And in their breath-defying flight,
Daredevils of a deep delight.

Of course, who would not rather be
An aerobat of ecstasy?
But it takes grounding to observe
Their every barrel roll and swerve

Against the sky, the way their skill
Makes the unseen visible
With two unlikely forces twinned:
Their turn of mind, the wanton wind.

Today’s Route: We visited the Children’s Garden bog and wetland area, then walked down the path to the Flower Bridge. We toured the China and Asia Section, the Physic Garden, and the Heritage Garden, then working our way down to the Orange Trail and the beaver pond. We returned to the Visitor Center on the Purple Trail and through the Florida Garden.

Pre-Ramble Observations by Heather and Don: As they often do, Don and Heather explored the plants in the Children’s Garden. Here are some of their finds:

Chrysanthemum lace bug, Corythucha marmorata, photo by Heather Larkin

The leaves of Maximillian Sunflower are defended by stiff hairs and gland dots that exude defensive compounds, but the Lace Bugs are apparently not deterred. Photo by Heather Larkin

Leaf Beetle Jumping Spider.
Jumping Spiders have short legs, big eyes, and stout bodies. They do not spin webs but create silken tents under logs and rocks and on plants and use them for hibernation.

OBSERVATIONS
Aubrey introduced today’s Ramble with a bit of background on two of the traditional medicines of Asia: Chinese Traditional Medicine and Ayurvedic medicine of ancient India. These systems differ from Western medicine in that a diagnosis will begin with an “energetic” and “constitutional analysis.” From this, traditional practitioners decide if their patient is “deficient” or in a state of “excess,” or is “cold” or “hot,” or has dry or excess heat, and so forth. Ayurvedic medicine looks at “Doshas,” which are the constitutions of their patient. Doshas fall into three broad categories: Vatta (Air) – a person of light quick nervous energy; Pitta (Fire) – a person with heat issues dominant; and Kapha (Earth) – that of physical form, lubrication, and nourishment. Then herbs that are considered hot, cold, moist, drying, stimulating, etc., are chosen to fit the diagnosis and put together into a specialized formula.

Whoa! Whatever happened to using mint for my aching tummy?! It is fine to use herbs by themselves or with a few herbs in a personally designed tea to treat a symptom you may have. This skill is called “simpling.” Remember to be respectful of the plants if you collect from the wild, never taking more than 5% of any plant’s population (per the Plant Conservation Roundtable’s guidelines). Some North American tribes called medicinal plants “the sisters who take care of us,” and frequently gave a token gift when they collected, such as a pouch of tobacco, a sacred plant. And be extremely sure of your identifications! Don’t rely on a quick look at an online identification app – there are many good field guides out there dedicated to medicinal plants!

Some of Aubrey’s field guides to medicinal plants.

Aubrey discussing the medicinal aspects of Willow bark

Aubrey led us to the Weeping Willow in the Children’s Garden. The inner bark of Willow trees, which contains salicin, has been used for centuries in both Europe and Asia for reducing inflammation, fever, and pain. Modern aspirin is a synthetic product called acetylsalicylic acid.

Aubrey discussing Horsetails in the Children’s Garden wetland, which is especially rich in medicinal herbs. We have two species of Horsetail in Georgia, Field Horsetail and Tall Horsetail. Both occur on stream banks and in floodplains.

Aubrey with horsetails (Equisetum hyemale)
Horsetails, Equisetum spp.

Tall Horsetail is widespread in North America and occurs as far south as El Salvador.

Horsetails are high in silica, and are also called Scouring Rush because they make a good dish scrubber. They may be beneficial for bones, hair, nails, and connective tissue. They also contain chemicals that may have antioxidant and anti-inflammatory effects.

Horsetails are ancient plants, having diverged from an ancestral plant about 342 million years ago. Like other primitive plants (e.g. ferns, mosses), they reproduce by spores. Their cone-like reproductive structures are held at the tips of the stems, each producing hundreds of spores.

Horsetail reproductive structures are cone-like strobili that produce spores.
American Lotus flower

American Lotus is found in lakes and ponds throughout eastern North America. It is in the same genus as its Asian relative, Sacred Lotus, which is used to treat diarrhea, insomnia, fever, body heat imbalance, and gastritis. The seeds and tubers of American Lotus were used as food by Native Americans.

The Seminole tribe ground the roots of Lizard’s Tail, also known as breastweed, and used the paste to make compresses for painful breasts.

Lizard's Tail, Saururus cernuus

Water-primrose, in the genus Ludwigia, has been used for its anti-bacterial and anti-diarrheal properties.

Pitcherplant bog with Sarracenia hybrids

Pitcherplant bog with White-top Pitcherplant hybrids

Pitcherplants were used by many Native American tribes for a variety of ailments.

Crampbark is a European species of Viburnum used to relieve the pain of menstrual cramps. Also known as Guelder-rose, it is planted in the Lower Shade Garden. This photo is of the cultivar ‘Roseum.’

Smooth Spiderwort, Tradescantia ohiensis

Smooth Spiderwort flowers make a nice addition to a salad! Some species of Spiderwort have been used medicinally by Native Americans, and recent studies have shown antioxidant and antibacterial activity in Spiderwort species.

Cedar Glade St. John's-wort, Hypericum frondosum

Cedar Glade St. John’s-wort, a Hypericum species that occurs throughout Georgia in dry uplands.

Many species of St. John’s-wort have medicinal properties. European St. John’s-wort (Hypericum perforatum) has been widely prescribed to treat depression, and Spotted St. John’s-wort (Hypericum punctatum) is used in a liniment is used in massage therapy.

A word about “worts”… A lot of medicinal plant names end with the suffix “-wort.” Wort is an old word, derived from Old English wyrt, meaning simply plant; wyrt originally came from wurtz in the ancestral language of both English and German, meaning root. Names with the -wort suffix usually referred to medicinal plants, with the prefix being the part of the body or the condition for which it was used. But not always: St. John’s-wort is named for the saint day of St. John the Baptist, June 24th, around which time Hypericum species bloomed in Europe. An article in Wikipedia lists nearly 200 species with the suffix -wort, including both Old and New World species.

Aubrey discussed the importance of Sweet Gum in Chinese medicine. Essential oils derived from the leaves and stems of Chinese Sweet Gum (photo, left) are used to make anti-inflammatory liniments and compresses. It occurs throughout China, Taiwan, South Korea, Laos, and northern Vietnam. Its leaves are usually three-lobed. The Sweet Gum native to eastern North America (photo, right) has five-lobed leaves. A 2019 study found that the native Sweet Gum is loaded with phenolic compounds and “…may be considered as a potential therapeutic source with high anti-inflammatory activity and synergistic interactions with antibiotics against bacteria.”

Indian Pink flowers, May 2

The roots of Indian Pink, also known as Pinkroot and American Wormgrass, were used as recently as the 1930s to rid the body of intestinal worms. However, every part of this plant is toxic, containing spigiline, a compound which causes nausea, vomiting, and convulsions. Indian Pink is in the Strychnine Family (Loganiaceae). This photo was taken on May 2 when the plants were in flower; they are now in fruit.

The Herb and Physic Garden, near the Visitor Center, contains many traditional English and early American herbal plants.

A native of Europe, Feverfew was traditionally used for the treatment of fevers, migraine headaches, rheumatoid arthritis, stomach aches, toothaches, insect bites, infertility, and problems with menstruation and labor during childbirth.

Black Cohosh, photographed in the Dunson Garden on May 16, is a native species that is also used for menstrual and childbirth problems.

Black Cohosh

Scarlet Bee-balm, a native species in the Mint Family, was used to treat bee stings as well as a wide variety of internal ailments.

Scarlet Bee Balm
Culver's Root

Cherokee and other Native Americans used Culver’s Root for a number of issues including coughs, fevers, rheumatism, childbirth, and constipation.

Here, Aubrey is discussing the uses of Garden Comfrey, a European species, used for relieving inflammation of the lungs and for healing of internal wounds and tissues. The native species, Southern Wild Comfrey, was considered by Native Americans to be a sacred healing plant, used primarily for gastrointestinal problems.

Aubrey discussing the uses for Comfrey
Elderberry

Elderberry flowers are on their way out today, soon to be replaced by large, flat clusters of purplish-black berries that are used to make jam, wine, and pies. The flowers are edible and are incorporated into pancakes and fritters. It is also considered a stimulant to the immune system due to its high levels of anti-oxidants. This article describes the wide range of uses that Native Americans had for Elderberry: dried fruit for sauces and survival food, twigs and fruit as dye, branches for arrow shafts, hollowed-out stems as flutes, and the pith for tinder.

Enslaved women on cotton plantations learned that chewing the roots of cotton plants could, among other methods, induce abortion, a way of resisting enslavement. An article detailing these and other other forms of enslaved women’s resistance is on the website of the Lowcountry Digital History Initiative.

Leaving the cultivated areas of the Garden, we walked downslope to the Orange Trail and the beaver marsh, where Duck Potato, also known as Wapato, is abundant. The large, arrowhead-shaped leaves are conspicuous.

In late summer, Duck Potato produces tubers at the tips of underground stems. They were an important food source for Native Americans. They can be eaten raw or boiled, fried, or roasted and taste much like potatoes.

On our return to the Visitor Center, we stopped to admire Gardenia shrubs in full bloom in the Flower Garden. We learned from Aubrey that the petals are edible and are made into a sweet-smelling tea. In Chinese medicine, the dried fruits of Gardenias are used to remove “damp heat” from the body.

Each flower is divided into four, thread-like
segments. The oval, blue-black fruits that appear on female plants in
late summer and fall betray this species’ membership in the Olive
Family. In the wild, it occurs in habitats as diverse as rock outcrops,
pine-hardwood forests, and shrub bogs.

Today’s emphasis:  
Looking
for frog eggs and flowering Butterweed in the Middle Oconee River floodplain

Number of Ramblers today: 30

Today’s Route: We left the Children’s Garden and headed down the White Trail extension to the power line right-of-way, stopping to look for ephemeral pools. We then followed the ADA trail to the river and turned left on the White Trail, following it to the spur that crosses the floodplain and returns up the hill. We took the spur trail back to the White Trail and returned to the Children’s Garden.

Announcements:


The April 18 ramble will be led by Catherine, who will lead us in another “art
ramble.”  Please bring a clipboard if you
have one. If you don’t, we will have a few spare ones. Also bring your creative
spirit!

The April 25 ramble will be led by Bay Noland-Armstrong, a graduating senior in
the Wildlife Resources Department in the Forestry School. She will teach novices
how to bird and give experienced birders a chance to hone their skills during
migration. Please bring binoculars if you have them; if you don’t, we will have
a few spares on hand. Also, download the Merlin app available free from the Cornell Lab of
Ornithology to your phone.

The Nature Rambler book group meets next on April 18 in the Adult Education
Classroom in the Education Department in the Visitor Center at the Garden. Richard
will moderate a discussion of The Life of a Leaf by Steven Vogel. 


The Garden has announced plans to re-route and convert the existing mulched trails
in the Dunson Native Flora Garden to paved, ADA-approved trails. Comments on
this proposed plan may be sent to the Garden’s Director, Jenny Cruse-Sanders (
crusesanders@uga.edu)
and the Garden’s Director of Horticulture, Jason Young (
Jason.Young@uga.edu).

The Garden’s Spring Plant Sale is this week. There will be a Friends Pre-sale
on Thursday, April 11, from 2:00 to 6:00 pm,with the general public welcome on Friday, 2:00 pm to 6:00 pm, and
Saturday, 8:00 am to 2:00 pm.


Interesting follow-up article to this week’s solar eclipse. An eclipse is wondrous — don’t underestimate
it.”


Show-and-Tell: 

Nathan brought a sample
of Oriental False Hawksbeard, an exotic invasive species
that has become incredibly widespread in just the last decade. Nathan
recommends that we pull it up before it goes to seed, taking care to get as
much of the root as possible. It’s a shallowly rooted plant and not hard to pull up.
More info is here.


Today’s Reading:  Linda read an essay
about a hummingbird building a nest from Barbara Kingsolver’s book Small
Wonder
.


“In the slender shoulders of the myrtle tree outside my kitchen window, a
hummingbird built her nest. It was in April, the sexiest month, season of
bud-burst and courtship displays, though I was at the sink washing breakfast
dishes and missing the party, or so you might think. Then my eye caught a
flicker of motion outside, and there she was, hovering uncertainly. She held in
the tip of her beak a wisp of wadded spider web so tiny I wasn’t even sure it
was there, until she carefully smooshed it onto the branch. She vanished then,
but in less than a minute she was back with another tiny white tuft that she
stuck on top of the first. For more than an hour she returned again and again,
increasingly confident of her mission, building up by infinitesimal degrees a
whitish lump on the branch-and leaving me plumb in awe of the supply of spider
webbing on the face of the land. When the lump had grown big enough 
when some
genetic trigger in her small brain said, “Now, that will do “
she
stopped gathering and sat down on her little tuffet, waggling her wings and
tiny rounded under- belly to shape the blob into a cup that would easily fit
inside my cupped hand. Then she hovered up to inspect it from this side and
that, settled and waddled with greater fervor, hovered and appraised some more,
and dashed off again. She began now to return with fine filaments of shredded
bark, which she wove into the webbing along with some dry leaflets and a
slap-dab or two of lichen pressed onto the outside for curb appeal. When she had
made of all this a perfect, symmetrical cup, she did the most surprising thing
of all: She sat on it, stretched herself forward, extended the unbelievable
length of her tongue, and licked her new nest in a long upward stroke from
bottom to rim. Then she rotated herself a minute degree, leaned forward, and
licked again. I watched her go all the way around, licking the entire nest in a
slow rotation that took ten minutes to complete and ended precisely back at her
starting point. Passed down from hummingbird great-grandmothers immemorial, a
spectacular genetic map in her mind had instructed her at every step, from
snipping out with her beak the first spiderweb tuft to laying down whatever
salivary secretion was needed to accrete and finalize her essential creation.
Then, suddenly, that was that. Her busy urgency vanished, and she settled in
for the long stillness of laying and incubation.”

OBSERVATIONS:

Eastern Red Columbine flowering
at the edge of the Children’s Garden

Flowering time of Red Columbine (and
several other species such as Red and Painted Buckeyes) usually coincides with the
arrival of Ruby-throated Hummingbirds, who fly across the Gulf of Mexico from
their wintering grounds in Central America. Our native Eastern Red Columbine has a special relationship with hummingbirds: their
red color is especially attractive to hummers and their nectar has twice the amount of sugar
as western Columbines.
Columbine flowers produce nectar inside the very tips of the “spurs” (modified
petals) that point upward at the top of the flower. As hummingbirds probe for
nectar, their foreheads pick up pollen from the flower’s stamens, pollen which
is hopefully transferred to stigmas on the next plant they visit. Columbine is
capable of producing viable seeds from self-pollination but repeated
self-pollination within a plant population carries the risks of inbreeding: populations
of plants with low genetic diversity are more vulnerable to disease and may lack
the ability to respond to changing environmental conditions.

Piedmont Azalea is planted at the
top of the paved path through the Lower Shade Garden.

Pollinators of native Azalea
flowers were a mystery for many years. The nectar is produced deep inside the
tubed portion of the flower, while the pollen-producing anthers at the tip of
the stamens are held inches from the tube. Not to mention the pollen-receptive stigma,
which protrudes even further than the stamens. How does an insect probing the
tube come into contact with all three important parts of this system: the
nectar glands, the anthers, and the stigma? North Carolina State University
biologist Mary Jane Epps found out the answer which you can read about here.

A Pale Yellow Trillium in bud

In mid-March, the Lower Shade and
Dunson Gardens are filled with flowering Sweet Betsy, Trailing (Decumbent), and
Chattahoochee Trillium. A few weeks later, the Pale Yellow Trillium emerges and
flowers. Like the Trailing Trillium and Chattahoochee Trillium, the Pale Yellow
Trillium is not native to the Athens area but was planted in Dunson to make a
microcosm of Georgia’s flora available to visitors. Pale Yellow Trillium is
found naturally only in moist ravines in a narrow zone along the Savannah River
in Georgia, South Carolina, and North Carolina. Many populations were lost
to the extensive damming of the Savannah River and the subsequent flooding of its
tributaries.

The tender leaves are protected
by a dense coating of hairs and just a blush of anthocyanin (on the smallest
leaf on the upper right).
Winged Elm bark is characterized
by narrow oblong plates that some wag likened to tongue depressors.
Trailing (or Decumbent) Trillium
occurs almost exclusively in Georgia’s northwest “limestone counties” but seems
to thrive in the Lower Shade and Dunson Native Flora Gardens. Its stems are
very short and curved (below), but don’t actually “trail” along the ground.

New Rambler Luna (left) and
Nathan (right) looking for insects and fungi under a log. They turned up a
beautiful, pinkish, resupinate polypore crust fungus (below).

The base of the slope just before
the White Trail emerges onto the right-of-way is a reliable place to find lots
of Rue Anemone, a wildflower that thrives at the Garden; deer avoid its
toxic leaves and stems. It starts blooming in early March and continues well
into May, pushing the envelope on the definition of a spring ephemeral. But
its seeds bear elaiosomes, so we’ll let it stay in the club.
By late summer, Ramblers are
pretty tired of the Garden’s weedy and ubiquitous Wingstems and Crownbeards, both in
the genus Verbesina. But backlit in early spring, the wings are a nice sight. As Dale would always point out to Verbesina detractors, these plants are the host for lovely
little Silvery Checkerspot butterflies.
Four-winged Silverbell trees at
the edge of the floodplain forest are in flower.
The largest and densest witch’s broom
we’ve ever seen


In the same area as the Silverbell, several Hop
Hornbeam trees bear large, dense clusters of twigs and leaves in their canopies that are called “witches’ brooms.” Elizabeth Little, the Nature Ramblers’ unofficial official plant pathologist, says: “a
witch’s broom is a plant growth abnormality characterized by a proliferation of
shoots with very short internodes that result in a dense bundle of twigs. The cause
varies with the type of plant. In the case of Hop Hornbeam, Hackberry, and Birch,
the interactions of fungal pathogens such as a Powdery Mildew fungus and
insects such as eriophyid mites damage terminal buds. The damage results in a
malfunction of the plant’s defense mechanisms leading to growth hormone
imbalances and uncontrolled growth.”

Ground Ivy, the third member of Don’s Three Amigos

Considering they are all in the Mint
Family, perhaps we should call them the Three Primas.The other members of this trio are Purple Deadnettle and
Henbit, below.

Ramblers searching for frog eggs
in the ephemeral pools along the ADA path to the river

The pools immediately adjacent to
the old unpaved path were lost to the installation of the ADA trail. There are pools
further into the vegetation thickets but we found they are inaccessible without knee boots. Spring
Peepers, Chorus Frogs, and American Toads have all been calling from here this spring.

The different world of the
flooded slough between the base of the slope and the Middle Oconee River levee
Box Elder is a common floodplain
tree with compound leaves

Bill spotted a Box Elder gall formed
by a tiny midge that lays its eggs on the leaves, leaf buds, and leaf stalks of
Box Elders. A gall forms around the egg and provides food for the larva after
it hatches from the egg.

Wildflowers in the Middle Oconee
River floodplain

Wild Chervil in flower beside the
White Trail along the river
A weedy native found along the
river bank, Kidney-leaf Buttercup has the extra-shiny yellow petals typical of
buttercups.

Buttercups get their color from
yellow pigments like many flowers do. But only recently have
researchers discovered the reason why buttercup flowers
are so much glossier than other flowers: “Buttercup’s
exceptionally bright appearance is a result of a special feature of the petal
structure. The epidermal layer of cells has not one but two extremely flat
surfaces from which light is reflected. One is the top of the cells, the other
exists because the epidermis is separated from the lower layers of the petal by
an air gap. Reflection of light by the smooth surface of the cells and by the
air layer effectively doubles the gloss of the petal, explaining why buttercups
are so much better at reflecting light under your chin than any other flower.”

Wood Nettle is a species of
stinging nettle that is abundant in the floodplain.

Wood Nettle’s stems and leaves
are usually covered with stinging hairs (they may be shed by the end of
summer). The glassy-looking hairs (below) are very brittle and, when brushed,
break open and release a stinging compound that can irritate skin for hours or
even days. Sufferers can console themselves with the fact that nettles are
larval hosts for Red Admiral, Eastern Comma, and Question Mark butterflies.

Several spring wildflowers have tiny
white flowers in small clusters. Beaked Corn Salad is distinguished by the
strongly forked (dichotomous) branching of its stems and by its opposite leaves.
It occurs in moist, frequently disturbed habitats such as floodplains.
Near the base of the ridge along
the spur trail, we saw Butterweed in the greatest numbers of any place we’d
seen them this morning.
Butterweed is an impressive
plant
 
often forming large populations 
with stout, ribbed stems and
large, showy flower clusters composed of many flower heads. Even the foliage is
impressive, each leaf divided into many differently shaped segments. Butterweed showed up in the Middle Oconee
River floodplain after the dense thickets of Chinese Privet were removed. It is toxic to mammals (including deer and humans). Butterweed
is a winter annual whose seeds germinate in the fall and form a leafy rosette that
overwinters and then sends up a single flowering stem in the spring.
Ramblers spotted a vigorously
flowering Cross-vine in a trailside tree. Cross-vine climbs by wrapping
tendrils around a supportive tree or fence.
Cross-vine is one of the showiest
of native vines, but the flowers are usually at the top of the tree that the
vine used as a scaffold to reach the sun. Though it’s now commonly grown on the
fences of native plant gardeners, it was a treat to get such a close look at
these flowers in the wild. The flowers are pollinated by hummingbirds and
butterflies.

A closer look at the stamens,
style, and stigma of the Cross-vine flower. There are four stamens, each tipped
with a small, oblong, pollen-producing anther, and a single style tipped with a sticky stigma.

Early Forget-Me-Not is covered
with long, bristly hairs throughout.
Annual Fleabane in early flower
Ramblers welcomed new member Luna,
whose stated objective for her first Ramble was to see a Carolina Anole. In the
Forest Play Area, she not only saw a Carolina Anole but was able to catch (and
release) one, as well.
At several locations during the
Ramble, ramblers using the Merlin app identified Northern Parula songs.Though none of these birds were photographed, Don
supplied a photo of a Northern Parula that he took in the Okefenokee Swamp with
Mal Hodges during one of their lichen forays.

emphasis:  
Seeking what
we find in the forests along the Green and Blue Trails.

Announcements:

Rambler
Kathy Stege invites all ramblers to join her for a moderate stroll on Thanksgiving
Day (2:00pm, Thursday, 11/23) at Heritage Park in Oconee County, on the west side
of Hwy 441 in Farmington – look for the big, old, white school house and white
fence along Hwy 441. The full walk is 1.5-2.0 hours, but there are plenty of
short cuts along the trail to return earlier. A fast group might split off in a
brave effort to work off their Thanksgiving feast calories. Bring your dog(s),
friends, and family. RSVP to Kathy by Wednesday 11/22 5:00pm: 478-955-34222
or kjstegosaurus@fastmail.com

Sandy
reminded us that the Nature Rambler book group will meet on Thursday, November
30, 10-11:30 a.m. in the Adult Classroom in the Garden’s Visitor Center to
discuss dates and times of future meetings and to select a list of books for
2024. Bring a book (or a description of a book) that you’d like the group to
read.

Linda
reminded us about the upcoming series of Winter Walks, beginning the Thursday
following Thanksgiving, December 7. Walks will begin at 10:00am at state parks
or natural areas within an hour’s drive (more or less) of Athens. Dale will
announce by email the location and a description of each walk on the Monday
prior. The list of destinations is not finalized: please submit suggestions for
places you’d like to visit.

Firefly art!  “This series of images is the result of photographing
a kind of magic only found in nature, a phenomenon with countless iterations
that is often unseen – fireflies. The primary subject is a synchronous firefly
population recorded in spring of 2023, deep inside an Athens, Georgia forest
during the peak of their mating season.”

Tim
told us of a recent trip to George L. Smith State Park, near Twin City, GA, in
Emanuel County. He recommends paddling its 400-acre black water cypress swamp that
has several different kayak/canoe trails. 

Reading: Kathy
Stege read Mary Oliver’s poem, “In our woods, sometimes a rare music.”

Every
spring
I
hear the thrush singing
in
the glowing woods
he
is only passing through.
His
voice is deep,
then
he lifts it until it seems
to
fall from the sky.
I
am thrilled.
I
am grateful.
Then,
by the end of morning,
he’s
gone, nothing but silence
out
of the tree
where
he rested for a night.
And
this I find acceptable.
Not
enough is a poor life.
But
too much is, well, too much.
Imagine
Verdi or Mahler
every
day, all day.
It
would exhaust anyone.

Today’s
Route:

We walked through the Dunson Garden, crossed the right-of-way, and entered the
woods where the White, Green, and Blue trails intersect. We
walked uphill along the Green Trail, turned west on the old service road, and then returned
to the right-of-way on the Blue Trail, where we took the White Trail back to
the parking lot.

Common
Eastern Bumble Bee
searching late-blooming goldenrod flowers in the Children’s Garden

Leaving the Children’s Garden plaza, we paused to
admire the bright colors of Beech leaves near the beginning of the Shade Garden path. It’s interesting to think that these bright pigments – carotenoids –
are present in the leaf all summer and appear only when the chlorophyll that masks
them breaks down in the fall.

American
Sycamore is a bottomland species often found in floodplains in wet areas as
well as on the drier levees. It also seems to thrive on the upland slopes of the
Shade Garden. Their “seed balls” are actually round clusters of
tightly packed fruits, each fruit with a tuft of tawny hairs to catch the
breeze as the seed balls disintegrate (below). Some people collect the balls
and hang them on trees near their houses to attract seed-eating birds such as
chickadees, goldfinches, and juncoes.

 

These
rosettes of Golden Ragwort leaves will persist through the winter and respond
quickly to next spring’s warm weather by putting up a flower stalk. Many of the
leaves have been thoroughly mined by leaf miners. “Leaf miner” is a general
term applied to the caterpillars (larvae) of moths, wasps, and flies that are
so tiny they live between the upper and lower surfaces of leaves, eating their
way through the leaves. You can spot the point on the leaf where the initial
egg was laid – the mining trail is very fine – and follow the progress of the
caterpillar as it eats and grows – the trail becomes wider as the caterpillar
does – until it finally exits the leaf at a brown spot. The number of brown
spots on this leaf suggests that five different caterpillars lived here.

Dried fertile
frond of Sensitive Fern, so named because its fronds are very
cold-sensitive and have withered while most of the other ferns in Dunson are
still green. Each of the small, dark “balls” on this frond are sori that produced spores during the summer.

This Cucumber Magnolia was planted at the threshold of the large foot bridge spanning the rock wash in the Dunson Garden. It’s always a pleasure to examine the patterns and colors of the many crustose lichens (below) that use its bark as a substrate.

Crossing the right-of-way
on the White Trail,
we stopped to compare
the late season appearance of two common species of bluestem grasses (Andropon):
Split-beard Bluestem and Brooms
edge. 

Splitbeard is
so named for the two diverging branches that make up its inflorescence; the bases of the two branches are still visible in the topmost inflorescence in this photo. The seed-bearing spikelets are already
dispersed and only tufts of hair remain. Note that the Splitbeard inflorescence is held at the tip of a
long naked (no leaves, no spathes) stalk. Below, Broomsedge spikelets are partially enfolded by leaf-like spathes all along the stalk. You can still see some fruits, with long hairs attached, escaping from
the spathe.

Into the woods…

Roger estimates the trees in the oak-hickory forest west of the right-of-way are 150 years old.

The Green Trail is locally
(very locally) famous because it runs through an area that supports the
only Shagbark Hickories known at the Garden. Several years ago, Dan Williams, forester/geologist
and last week’s ramble leader, mapped the location of amphibolite bedrock in
the Garden in this area. On the map below, the amphibolite zone is outlined in
red and overlaps the area where the Shagbark Hickories grow.

Amphibolite is high in
calcium and magnesium, two minerals that “sweeten” (raise the pH) the soils
that develop above amphibolite bedrock. Many plant species, Shagbark Hickory among them, are
calciphiles – “calcium lovers” – found almost always where the soils are
sweeter. The northwestern corner of Georgia is underlain by layers of sandstone
and limestone and, where the limestone is the near the surface, the forests there are
often filled with Shagbarks and other calciphile plants. Closer to Athens, Shagbark
and other calciphiles can be seen on War Hill at Kettle Creek Battlefield in
Wilkes County.

Shagbark Hickory bark is broken into long and narrow plate that are loose at the top and bottom and attached to the trunk in the middle.

Even though loose, the plates still have the braided look that characterize hickory bark.

White Oak bark sometimes has a shaggy look too but never looks braided and the plates tend to be loose on one long side and attached on the other side.

While looking
through the leaf litter for Shagbark Hickory nuts, Page found a beautiful Green
Stink Bug.
Winged Elm is a reliable member of the Piedmont Oak-Hickory forest, easily recognized by its “tongue depressor” bark.
Mockernut Hickory
has the most distinctly braided bark of all the hickories. There are five hickory species at the Garden: Mockernut, Shagbark, Sand, Pignut, and Red.

Pignut
Hickory
is so named because its nuts were eaten by wild pigs and reportedly made
for excellent pork. Conveniently for our ID purposes, the husk
enclosing the nut has a “pig
snout” on one end. Pignut has tough, durable wood that was used for ax
handles and wagon wheel hubs. The husk splits at the fat end but opens only about a third of the way down.

Shortleaf Pine
bark with resin pits (aka pitch pockets) on the bark plates

Resin is an important defense against invasion by insects and fungi, and resin canals or ducts are found throughout the body of many tree species.
Shortleaf Pine
is unique among southern pines in having the canals reach the surface of the
bark, where they look like tiny moon craters.

This
Black Cherry tree beside the Blue Trail has developed a large burl, probably as a result of invasion by a pathogen.

Black Cherry trees
have distinctive, dark bark that is broken into many small plates that
some people liken to burnt, smashed potato chips. Up close (below), you can see that some of the plates are
crossed by lines of lenticels, patches of loose cells that allowed the young, rapidly growing tree to
take up carbon dioxide and release oxygen through its bark. These horizontal lines are quite
obvious on young Black Cherry bark.

A lot of people dislike Black Cherry trees because they pop up in gardens and shrubbery and, if left in fence rows, their poisonous leaves can be eaten by livestock. But Doug Tallamy has a different take on Black Cherry, and ranks it as  #2 on the list of plants that are the best larval host for lepidoptera
(White Oak is #1). This short and sweet video of Doug explains all.

There
is growing concern that Lenten Rose (Hellebore) may be escaping from
gardens and becoming invasive. In the woods along the Blue Trail, we saw
Lenten Rose that probably escaped from plantings at the Garden’s old
horticulture headquarters that occupied
the space now home to the Mimsie Lanier Center for Native Plant Studies.

Late in the year as it is, Don is still finding insects along the trail; in this case, he flipped over a Beech leaf and found a winged Tulip
Tree aphid and, at a fraction of the size, a leafhopper nymph (below).

Don spotted a dried
leaf with thirty or so Chalcidoid wasp larval cases attached to it. Chalcidoid
wasps are members of a large wasp family most of which lay their eggs on the
larvae, pupae, or eggs of other insects. Chalcidoid wasps are widely used as biological control agents to
kill agricultural pest insects.

Last ramble of the year  

Thanks to everyone who came out to ramble in 2023, with special thanks to the folks who led rambles, brought readings, shared show-and-tells, told funny stories, made hickory milk and yogurt, recommended books, made banners, asked hard questions, shared insights, and spotted cool stuff in the woods and gardens. It was a fun year, and we look forward to seeing everyone the first Thursday of March in 2024! Linda, Don, and Dale
