…this.

I was Googling for a flower photograph the other day and stumbled on Flora Pittsburghensis, a blog by Christopher Bailey. 

For those of you unfamiliar with this blog — as I was until this week — it’s a great resource on the wild flowers of Pittsburgh.  Bailey photographs native and alien wildflowers in our area, then tags them by family and posts them with extensive descriptions, primarily from Gray’s Manual. 

This morning glory was his subject on September 1st.

Flora Pittsburghensis is a treasure chest of beauty and information.   Click on the photograph to read for yourself… and enjoy!

Here’s a plant most of us ignore until its seeds follow us home.

The flowers of Beggar Ticks (Bidens frondosa) are rather inconspicuous but each of its numerous seeds has two tiny hooks that cling to fabric and fur. 

I bet you recognize the seeds on this sweater…

…which explains why another name for the plant is “Sticktight.”

Asters are blooming everywhere now and they’re notoriously difficult to identify.  So many look alike!

Is this one a New England aster?  Dianne Machesney photographed it at Cape May which is well within its range.

What do you think?

In late summer the grass doesn’t grow fast and we all get a break from cutting it.  In our yard we have a good crop of weeds because we don’t use weed killer and the grass has gone dormant during this month’s dry spell. 

The dominant weed in our yard is English plantain, raising its bald, knob-like flower heads eight inches above the grass.  It’s the only thing that needs cutting.

My husband debates with me, “Do I really need to run the mower over those knobs?  The grass is short.”  We aren’t gardeners so the plantain stays.

In Maine they have much prettier weeds.  The grass is going dormant here too but instead of ugly English plantain, their hawkweed is in bloom. 

Hawkweed is in the Aster family and there are many varieties.  The flower I see in Maine yards is probably Field Hawkweed or Pale Hawkweed.  Both grow one to three feet tall and produce pretty yellow flowers.  In mowed areas the flowers don’t reach that height so they’re about as tall as my plantain. 

In my opinion Hawkweed of any kind is much prettier than dandelions. 

No debate here.  Don’t cut the hawkweed!

Arrowhead is blooming now in a wetland near you.  This plant is at Green Cove wetlands in Washington County.

Watch for Boneset (Eupatorium perfoliatum) blooming now in western Pennsylvania.

Boneset’s common name comes from the old-time theory that boneset’s joined leaves meant it would heal broken bones.  Its scientific name, perfoliatum, also refers to the joined leaves which are perforated by the plant stem, as shown above.

If you haven’t seen boneset blooming yet, you can find it at Jennings Prairie.

A week ago this flower had me stumped when I found it at State Gamelands 95 in Butler County. 

The plant is six feet tall and has big, lobed, alternate leaves, but how to describe the flower?  It looks like it never opens.  Nonetheless I posted my vague description of it on PABIRDS and hoped someone would enlighten me.

My description must have been adequate because at least five people responded and all of them said, “It’s Pale Indian Plantain, Arnoglossum atriplicifolium (L.) H. Rob.”

In case you come across it and are stumped too, this is what it looks like. 

But one photo isn’t enough.  The picture above is a closeup of the flower umbel by Marcy Cunkelman.  Click here for a view of the entire plant by Dianne Machesney.

Now you know.

Here’s a beautiful flower that used to stump me every year when I found it near the bridge at Jennings Prairie.

This is Hairy Willow Herb (Epilobium hirsutum), a plant in the Evening Primrose family that stands two to six feet tall.  Like all Primroses, the flowers have a distinctive cross-shaped pistil.  This should have tipped me off.

Hairy Willow Herb can be invasive, though it was well behaved when I first found it years ago.  I wonder if it’s gone crazy now in the wetland under the bridge.

If you’d like to find out, join the Wissahickon Nature Club at Jennings Prairie tomorrow at 10:00am for a bird and wildflower outing lead by Esther Allen, Chuck Tague and Dianne Machesney.  For information and directions, click on the “Nature Walks” link here or call Susanne at 412-771-4737.

Deep purple and shaped like a shooting star, we’d cultivate this flower in our gardens if the rest of the plant was cooperative.  But it isn’t.

Bittersweet Nightshade (Solanum dulcamara) is a woody perennial vine that drapes itself over nearby vegetation.  The plant looks scraggly and the flowers are small.

It’s blooming now in my neighborhood in untended plots and all the places we forgot to weed.  I can’t help but notice it though, because I like the color purple.

And that makes this plant is one of my recurring topics.  See my blog about its poisonous fruit.
