Why Wild Geranium is Called Cranesbill

North America’s wild geranium (Geranium maculatum) is also called cranesbill but you have to examine a seed pod to find out how it got the name.

Shown above is a wild geranium flower with some aging seed pods in the background.  Here’s a closeup.

Ta da!

Now Blooming: Few-Flowered Valerian

This is a stellar year for Valeriana pauciflora at Raccoon Creek Wildflower Reserve in Beaver County, PA.  Its common name is “Large-flowered Valerian” but its scientific name means “Few-flowered.”  Confusing!

To find this 1.5-3-foot tall wildflower, walk the Jennings Trail between the two Beaver Trail intersections (along the cliff) or visit the spot where Jennings meets Meadow Trail and the creek.   Click here for a map.

Read more about its confusing name in the Throw Back Thursday article below.  Visit the Wildflower Reserve soon to see it.

A Smell That Reminds Me of Warblers

Published by under Plants

The smell of this plant reminds me of warblers.

Cypress spurge (Euphorbia cyparissias) is a perennial, 4-31″ tall, with narrow small leaves and green-yellow flowers that bloom from March to September.  It was introduced to the U.S. as an ornamental in the 1860s and often planted in cemeteries where it earned the nickname “graveyard weed.”  Its introduction was a terrible idea for a number of reasons:

  • The entire plant contains a toxic latex that irritates skin and eyes and is poisonous to many animals.  It can be fatal to cattle, though sheep can eat it.
  • It spreads via roots and explosive seed pods. If a farmer plows a field containing a bit of cypress spurge, his equipment will carry cut rootlets to other fields where it will take hold.
  • The plant is very invasive, forming almost pure stands.  It has no enemies in the Western Hemisphere so scientists had to import a few insects that eat it.

Cypress spurge thrives in sandy soil so it’s no surprise that it grows at Presque Isle State Park, crowding out native lupine and puccoon.  During warbler migration its scent is on the wind.  I don’t like the smell but I’ve had so many great birding experiences at Presque Isle in May that my brain automatically thinks of warblers when I smell it.

Fortunately the sick-sweet scent brings back happy memories for me.  For those who mourn a loved one in the presence of graveyard weed, the smell probably makes them sad.

Is there a smell that reminds you of birding?  Here’s an article that explains why smells trigger memories and emotions.

Named For A Dolphin

This weekend is a good time to take a wildflower walk in western Pennsylvania.  When you do, you’ll find dwarf larkspur blooming.

I just learned on The Allegheny Front that its scientific name, Delphinium tricorne, comes from the word “dolphin.”

Click here to learn how it got this name and other cool facts on an audio wildflower walk on The Allegheny Front.

Blooming This Week

Early saxifrage, Raccoon Creek Wildflower Reserve, 17 April 2016 (photo by Kate St. John)

Wildflowers are blooming throughout the Pittsburgh area.  This week I traveled southeast and west to record their progress.

At Raccoon Creek Wildflower Reserve on April 17 the earliest flower — skunk cabbage — had disappeared among the plant’s large leaves.  Toad trillium (Trillium sessile), wild blue phlox (Phlox divaricata) and early saxifrage (Micranthes virginiensis) were open. White large-flowered trillium was not.  I found an interesting sedge but I don’t know its name.

Braddock’s Trail Park in Westmoreland County has a south-facing slope so it’s flowers were much further along than Raccoon, even though I visited a day later.  Small-flower crowfoot (Ranunculus micranthus), Canada violets (Viola canadensis) and rue anemone (Thalictrum thalictroides) were in full bloom while blue-eyed Mary (Collinsia verna) carpeted the forest floor.  Trillium were already at their peak.  Dwarf larkspur (Delphinium tricorne) had just begun.

Click here or on the photo above for a slideshow of the flowers.  (Unfortunately the sun was so bright that it washed out the details of white flowers … I tried anyway.)

Look for wildflowers this weekend before the trees leaf out. Go north to see early flowers. Go south to see late blooms.

When the woods are in shade the flower party will be over.

Blue-Eyed Mary in Bloom

Published by under Phenology,Plants

It’s cold this morning — and snowy for some of you — but when the weather improves you’ll find …

Blue-eyed Mary (Collinsia verna) usually blooms in southwestern Pennsylvania from mid April to early May but we found it at Cedar Creek Park on Wednesday April 6.

This annual drops its seeds in summer, germinates seedlings in the fall, and overwinters to bloom in the spring.  It spreads by reseeding so you usually find it in patches — that look more green than blue from a distance.

Collinsia verna grows in woodlands with light to dappled shade and moist to mesic rich loamy soil.  Though the plant can be locally abundant, its habitat can be hard to find.  Blue-eyed Mary is endangered in New York and Tennessee.

Here are three places in southwestern Pennsylvania to see Blue-eyed Mary this month:

Too Early Spring

Spring is coming in fits and starts but mostly it’s coming too soon in southwestern Pennsylvania.

On Easter Day I took a walk at Cedar Creek Park in Westmoreland County and found native plants blooming two to three weeks ahead of schedule.  No wonder! It was 75 degrees F.

At top, bloodroot (Sanguinaria canadensis) was already blooming. Some had gone to seed.

Spring beauties were everywhere. This Carolina spring beauty (Claytonia caroliniana) is identifiable by its wide leaves.

Get outdoors as soon as you can!  Spring could pass you by.

 

p.s. The Botanical Society of Western Pennsylvania is already alert to this early growing season.  They moved up their snow trillium outing from April 2 to March 20.

Schenley Park Last Week

Spring is early, as expected, so I wasn’t surprised to find leaves unfurling in Schenley Park last week.  Here are a few highlights from my walks in the past nine days.

Above, coltsfoot (Tussilago farfara) began blooming on March 7 and was still flowering when I passed by on March 24.

Below, Ohio buckeyes (Aesculus glabra) are one of the first trees to leaf out in Schenley Park.  These leaves picked up fluff from other trees whose flower parts had blown away, perhaps a wind dispersal strategy.  The buckeye makes flowers that attract bees.

Purple deadnettle (Lamium purpureum) began blooming March 10 and will continue for many weeks. Its flower has a spotted lip that says, “Land here, little insect.”

The weather’s been mild so get outdoors soon. Don’t miss our early Spring.

Happy Easter!
