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.

Cypress spurge (Euphorbia cyparissias) is a 4″-31″ tall perennial with narrow 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.
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?

Last month I listed outings for the last week of April and included May 1. Here’s a big list for the month of May.
Everyone is welcome to participate in these outings. Click on the links for directions, meeting places, what to bring, and phone numbers for the leaders.
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.
They were so beautiful that I made 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.
Flowers are blooming everywhere and trees will soon leaf out. Don’t miss your chance to get outdoors while the weather’s fine.
Join me for a bird and nature walk in Schenley Park this Sunday, April 24, 8:30am – 10:30am. Meet at the Schenley Park Visitors Center. Click here for information and updates.
Or join one of these many outings — April 23 through May 1.

p.s. The flower shown above is a member of the Pink family called star chickweed or great chickweed (Stellaria pubera). It looks unremarkable until you get close. 🙂
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:
Spring is coming in fits and starts but mostly it’s coming too soon in southwestern Pennsylvania.
On Easter Day, 27 March 2016, 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.
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, Yellow buckeyes (Aesculus flava) 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.
