Thimbleweed

Thimbleweed, Armstrong County, 12 July 2014 (photo by Kate St. John)

There aren’t many flowers that bloom in the woods in the summer, but you might find this one.

Thimbleweed (Anemone virginiana) stands 2-3 feet tall in the sun-splashed forest.  The flower has an elongated central disk surrounded by large white petals and is noticeable because it’s alone on a long stalk above the leaves.

When the flower is fertilized, the petals fall off and the central disk becomes a seed pod.  It looks like a thimble, hence the name.

I found this one blooming at the Roaring Run Watershed in Armstrong County last weekend.

Detective Work

Perfoliate, alternate, entire (photo by Kate St. John)

Today we’ll have a plant identification quiz.  I have an answer but you may have a better one.

I found this plant on June 29 at Dead Man’s Hollow in Allegheny County.   The leaves are so distinctive that its identity begs for some detective work.  Here are the clues I gathered:

Leaves:

  • alternate on the stem,
  • edges are entire (not toothed),
  • leaves are perfoliate.  (The stem perforates the leaves, a very cool feature.)
  • bottom leaves are larger than the violet leaves nearby.

The plant had no flowers and no buds.  Instead it had developing fruits which gave me clues about the flowers.  Here are two photos of the fruits.

The fruits are:

  • on stems that sprout from perfoliate spots on the leaves
  • three sided with a seam in the middle of each side.  Does this mean the flower was three-petaled or six-petaled?
  • still maturing?  Or are they in their final form?

I looked up “six petals with alternate, entire leaves” in my Newcomb’s Wildflower Guide and found a familiar spring wildflower with perfoliate leaves.

However, I am not completely satisfied with my identification.  I have never seen “my plant” arc horizontally like this when it’s blooming and the fruits in the illustration look different.  Is my Newcomb’s Guide missing a species?  Have I never noticed that the plant “lies down” in the summer?  Are the fruits going to match the illustration when they mature in a few weeks?

So here’s the quiz:  What plant is this?

Leave a comment with your answer.  I’ll post my guess after I’ve heard from you.

UPDATE:  It is large-flowered bellwort (Uvularia grandiflora). See the Comments for a link to the flowering version of this plant.

Why It’s Called Wingstem

Two months before it blooms we can identify this plant even though it has no flowers.  Look at its stem!

Wingstem (Verbesina alternifolia) is already five feet tall and on its way to eight.  It will look like this in August.  Meanwhile the stem gives away its name.

The “wings” are petiole extensions that run the length of the stem.  The newest wings at the top of the plant are straight with a dark margin. The older part of the stem has long white hairs in the margins. Sometimes the wings are wavy.

To me the wings look like flanges.  “Flange-stem?”

Say that three times quickly and you’ll know why it’s called wingstem!

Green Flowers

Flowers of Indian cucumber root, 22 June 2014 (photo by Kate St. John)

It seems odd that a plant would have green flowers but a surprising number do including jack-in-the-pulpit, northern green orchid and ragweed.

In mid-June I found a blooming Indian cucumber root (Medeola virginiana) that I nearly missed because the flowers didn’t stand out.  The top two had already gone to seed and those in bloom were camouflaged in a greenish yellow way.

The bottom whorl of leaves caught my attention.  It’s typically five to nine long leaves (this one had seven) suspended a foot or so above the ground.  Only the blooming plants have the smaller top whorl too.

I tried to take a picture of this arrangement but even my best photo is confusing.  The small flower whorl blends in with a second plant behind it even though the background is beyond the mossy log.

Having paused to take a photo I knelt down to see the flowers.  This perennial is pollinated by insects, probably flies.  The color green makes sense for flies as they don’t need fancy red, white, yellow or purple to be attracted to the plant.

Indian cucumber root earned its common name when Native Americans taught the settlers that the edible root smells and tastes like cucumber. People still dig and eat it today, thereby destroying the plant.  It’s endangered in Illinois and Florida.

Though not threatened in Pennsylvania, I won’t say the exact location of this flower.  Only that I found it in the Laurel Highlands, an area encompassing 3,000 square miles.

A Native Portulaca

Round-leaved Fameflower (photo by Dianne Machesney)

This Pennsylvania threatened plant is in the Portulacaceae family, related to our garden variety Portulaca.  Look closely at its thin, round, succulent leaves and you’ll see the family resemblance.

Round-leaved fameflower  (Talinum teretifolium), also called Quill fameflower and (Phemeranthus teretifolius), is found in rocky or sandy soil from Pennsylvania southward to Georgia and Alabama.

Dianne Machesney found this one last week at serpentine barrens in Chester County.

It was a Life Flower(*) for her. It would be one for me, too.

TBT: From the Hummingbird’s Point of View

… Throw-Back-Thursday: What does a hummingbird see in here? …

Facebook has Throw Back Thursdays (TBT *) and now, so do I.

I’ve been writing Outside My Window since November 2007 and accumulated more than 2,320 articles.  Many of them are great information that I’ve almost forgotten, so today I’m starting my own Throw Back Thursdays to reprise some really cool stuff.

Let’s re-explore the inside of a nasturtium.  Did you know it has a special structure just for hummingbirds?

Ohio Spiderwort

Ohio Spiderwort, 14 June 2014 (photo by )

On June 14 Karen Lang and I looked for fledglings at two peregrine nest sites along the Ohio River.  When we got to Monaca Karen pulled into an open area between a house and an old industrial site on the upriver side of the Monaca-East Rochester Bridge.  All around us the edges were blooming with bright blue flowers.

Ohio spiderwort, Tradescantia ohiensis or bluejacket, is a native perennial that’s often cultivated.  It’s tall and showy but each flower lasts only a day.  According to the Lady Bird Johnson Wildflower Center, “When touched in the heat of the day, the flowers shrivel to a fluid jelly.”  (Click here for another view.)

The flowers were also blooming in the homeowner’s garden so my hunch is they spread on their own to the river’s edge.

It’s fitting that Ohio spiderwort grows next to The Ohio.

A Plant With Four Names

Bowman's root, Gillenia trifoliata (photo by Tom Potterfield, Creative Commons license on Flickr)

On the day we saw the upland sandpipers Carole Winslow showed me a “Life Flower”(*) growing by the road.

The delicate flowers of Bowman’s Root (Gillenia trifoliata) have five petals, but they’re arranged irregularly as you can see in Tom Potterfield’s photo above. When the flower fades each petal falls alone leaving three and four-petaled flowers to confuse us amateur botanists.

I took a (poor) photo of the profuse flowers and drooping stems.  They look as if the rain beat them down but this perennial just won’t stand upright.

Gillenia trifoliata has two scientific names because there was a big disagreement about its first one.  Conrad Moench named it Gillenia in honor of German botanist Arnoldus Gillenius, but another of Gillenius’ fans later named a completely different plant Gillena in his honor. Professor Britton decided that the single letter “i” was not enough to distinguish the two names so he renamed Bowman’s Root Porteranthus trifoliatus in honor of his friend, Thomas C. Porter.

Which name is right?  In scientific naming there’s a rule that the first name takes precedence unless, of course, the organism is reclassed.  As we have seen with warblers, the Dendroica genus name completely disappeared when American Redstarts, Setophaga ruticilla, were reclassed into the Dendroica genus.  Because Setophaga is an older name the American Ornithologists’ Union declared that Setophaga replaced Dendroica. (Don’t get me going on how much I hate this!)  Apparently botanists made no such pronouncement on Gillenia so both names continue.

Bowman’s Root has another common name, Indian Physic, because Native Americans used the powdered root for an emetic (bleah!) and other medicinal uses.

Four names are a heavy load for these ethereal flowers.  I like to call them Bowman’s Root.
