March 20 2014 Ramble Report

First, a useful link: Many of our Nature
Ramblers are gardeners and interested in using native plants. A blog written by
Ellen Honeycutt has a lot of interesting information about this subject and she
gardens in the piedmont of Georgia, as well. You can find it here

The link to Don Hunter’s photos of today’s ramble is here.

 

And now, the Ramble Report, written by
Hugh Nourse.

Today, with better weather, 23 Ramblers
assembled in the lower parking lot, for a wildflower walk.  We tried an ambitious route:  through the flower gardens to the Orange
Trail, up the Orange Trail to the Upper Parking Lot, White Trail to the new
Prairie area, through the Dunson Native Flora Garden, then to the fence under
the power line along the White trail spur, returning to the Lower Parking Lot
by the White Trail up the hill.

Today’s reading was brought to us by Lee Boyer:

Big Haul From a Georgia Tree.

A telephone message from Terrell,
Catawba county, Georgia, furnishes the following interesting story:

Monday afternoon Luther and Lester
Sherrill, Fred Settlemire, Ransom and Walter Eades sallied forth to rob a
“bee tree,” and taking their axes they began chopping on the butt of
an old red oak tree measuring three and one-half feet in diameter. It was not a
great white until they struck hollow and to their delight as well as surprise
out walked an old possum. After carefully fastening her to a split limb another
raid was made, when thirteen baby possums were captured. The tree was finally
felled and from near the top they caught two pretty gray squirrels, captured a
swarm of bees and gathered a small quantity of honey.

From Anaconda Standard, (Anaconda, MT), August 21,
1910.  Also appeared in newspapers of Baltimore, Beaumont, TX, and
Aberdeen, SD.

Our first stop was in the Endangered
Plant Garden to see the Alabama Snow-wreath (Neviusia alabamensis) in bloom. 
There are five known populations in Georgia.  They are in the Ridge and Valley Province
because the habitat for this plant is “Moist, hardwood forests over rocky,
limestone-based soils, often along streams below sandstone caprocks”
(Linda Chafin, Field Guide to the Rare Plants of Georgia, 2007)

In the Indian Plants Garden, Rue Anemone
(Thalictrum thalictroides) was in
full bloom.  The plant several years ago
was named Anemonella thalictroides,
which is a plant like Anemone like a thalictrum.  On the surface they do not seem to look like
the other Thalictrums (meadow rues).  It
is reported that some people have used the roots as a potato.

Paw Paw flowers start to open

Going toward the Heritage Garden we
stopped at the Paw Paw trees (Asimina
triloba
), which were in bud.  The
buds were just beginning to open.

As we rambled around the Heritage Garden
we passed the fragrant winter honeysuckle (Lonicera
fragrantissima
), an asian plant that has become naturalized.  You could smell it several feet before
reaching the plant.

After passing through the gate of the
Garden’s deer fence, we found a group of blood root (Sanguinaria canadensis).  Native
Americans used the red from the roots for paint, and parts of the plant for
medicinal purposes.  In fact, a number of
years ago, a company made a mouthwash and toothpaste containing sanguinarine
from this plant.  My dentist suggested
that I use it.  The resulting white
lesions in my mouth called a halt to the experiment.  It must have happened to a lot of people
because it was taken off the market.

Roundlobe hepatica with new leaf

The next discovery before crossing the
stream was a group of bloodroot, round-lobed hepatica (Anemone americana), and rue anemone, all in a small patch among
rocks by the trail.  In the place by the
bridge over the stream where we found the first hepatica back in January was
still occupied by a hepatica in bloom.

Mayapple popping up

Along the trail by the stream we found
rue anemone, bloodroot, and emerging leaves of mayapple (Podophyllum peltatum), as well as a few fiddleheads from Christmas
ferns (Polystichum acrosticoides).  The blueberry (Vaccinium elliotii) was not yet in bloom.

Near the deer fence toward the end of the
Orange Trail, we stopped to discuss the crinkly bark of the older Black Cherry
(Prunus serotina).  Emily has called it “burnt potato
chips.”

Possible Bradford Pear

We went up the hill to the upper parking
lot and connected to the White Trail down to the Prairies.  Along this route we stopped for a blooming
fruit tree, which after some discussion, we decided was a Bradford pear tree (Pyrus calleryana ‘Bradford’).  It is a cultivar that has been planted so
much that it has escaped to the woods.  A
major problem that has occurred with this plant is that the tree tends to split
in the crotch of the main branches. 

[Note: for more information on the invasive
nature of Bradford pear read this post
by Ellen Honeycutt
.]

As we turned the corner at the Prairie
Garden, we noted the Black Cherry with burnt potato chip bark at the base, but
farther up exhibited the more typical grey bark with horizontal lenticels.

Ground ivy, Purple dead nettle, Hen bit (L. to R.)

Dale showed the differences in the
various ground cover plants that grow up along the trail here: hen bit (Lamium amplexicaule), purple dead nettle
(Lamium purpureum), and ground ivy or
Gill-Over-The-Ground (Glechoma hederacea).  These were all mints with square stems.  Tiny bluets (Houstonia pusilla) with their red centers and four blue petals were
also present.

Spring beauty
Colony of yellow trout lilly

Going through the Dunson Native Plant
Garden was an adventure in advancing spring. 
The spring beauties (Claytonia
carolinana
) were showing white, but it was probably too cold in the day to
open. We discussed the difference between the colonial-growing yellow trout
lilies (Erythronium americanum) and
the more solitary dimpled trout lily (E.
umbilicatum
).  One difference is that
the first is colonial. Second, there is an ear on the inner tepals of E. americanum.  Another difference is that the capsules
(fruit) of E. umbilicatum  are indented at the top and lie flat on the
ground.

Chattahoochie trillium
Decumbent trillium

It looked like deer had been munching the
clump of meadow rue as well as a lot of the trilliums.  The only trilliums in bloom were
Chattahoochee trilliums (T. decipiens),
sweet Betsy (T. cuneatum), and
decumbent trillium (T. decumbens).  All were traveling all over the Garden
probably being moved by ants.

 

Toothwort

By the
bridge Don pointed out the toothwort (Cardamine
concatenata
, or Dentaria laciniata).

Golden Ragwort starting to bloom

In amongst the ragwort (Packera aurea) we discovered a
bloodroot.  The sign for it was on the
other side of the trail behind which there was no bloodroot.  Bloodroot is another plant whose seeds are
dispersed by ants. We noted the bluish buds of the ragwort which will become
yellow flowers, and we did find one showing some color.

The leaves of the tiny trillium (Trillium pusillum) were up but they were
yet to flower.  But Virginia Bluebells
were in full bloom, and beside them were some blooming trout lilies (E. umbilicatum).  At a turned over tree stump one trout lily
was blooming.  The curator at the time
the tree fell decided to leave the plant on the stump, and it is still blooming
after several years.

We noted the spread of the leatherwood
shrub (Dirca palustris).  For some newcomers we explained about why it
is named leatherwood.  The twigs are so
limber that Native Americans used them for wrapping stuff.

“Edna’s” trillium (Persistent trillium)

We found more spring beauties,
toothworts, and a few rue anemone.  But
then we stopped at the rare persistent trillium (Trillium persistens). This species was only recently named.  The plant does not appear in Wilbur Duncan’s
first wildflower book published in 1975. 
(The late Wilbur Duncan was a botany professor at UGA for many years and
curator of the herbarium. He described several species of plants from Georgia
that were new to science.)  Edna Garst
saw this Trillium near their summer
home near Panther Creek and wanted to know what it was. She and her husband, John,
took it to Wilbur for identification.  He
had a specimen, collected much earlier, that he was puzzled by.  He and John researched the plant and were
able to write an article in 1971 naming it for the first time.  Most of us in the Athens area call it
“Edna’s Trillium.”  It is
endemic to Georgia and part of South Carolina.

We rambled through the power line right
of way to the White Trail spur to find a truly outstanding collection of rue
anemone that Dale and Emily had found recently. 
They were much more robust than any of the plants we had previously
seen.

For those who are interested, Dale and I
are leading a walk for the Georgia Botanical Society on Sunday at 1PM.  We will meet at the Arbor here at the Garden.
Anyone is welcome to join us. It is likely to be longer than our usual rambles are,
and will probably cover much of what we did today.  Emily reminded me that it counts for one of
the field trips required for the Native Plant Certificate.

It was time to retire to Dondero’s for
snacks and good conversation.
