What to Expect Outdoors Through Mid December

Today is Throw Back Thursday with a twist: I’m looking back to a phenology list that predicts the future.

What can we expect outdoors in the next 4-6 weeks?

My list from 2008 was based on our normal weather for late November and early December but the Earth is experiencing a strong El Niño this year.

Will the old predictions will hold true or will they be delayed?

Click here for What To Look For Through Mid-December and compare the predictions as time unfolds.

A Late Fall

12 November 2015

Fall seems late this year.

The leaves were late to change color and stayed on the trees longer than expected, temperatures last week were 15 degrees above normal, and the ducks are late arriving from the north.  In my city neighborhood we haven’t had a really hard frost yet.

Have you noticed this, too?

A strong El Niño is warming the northern U.S. and southern Canada this fall (red on map below).

Without ice forming on the northern lakes, waterfowl have no compelling reason to come south.  When do you think the big flocks will arrive?

Get Out To See Fall Colors, But Don’t Take The Bridge

The trees are still colorful in Pittsburgh but frost is coming tonight.

Get outside today to take in Nature’s beauty … but don’t expect to cross the Greenfield Bridge into Schenley Park.

The Greenfield Bridge is closed now for 18 months (probably 2 years!) while it’s dismantled, blown up and replaced.

Today, October 17, there’s a party on the bridge — Greenfield BridgeFest — from 4:00pm to midnight. Music headliner: Joe Grushecky and the Houserockers. Win a chance to be the one to blow up the bridge.  Click here for more info.

Come on down!

Throw Back Thursday (TBT):

What should we expect outdoors in late October?

Colorful leaves, fruits on trees, the first frost … and more in this Throw Back Thursday article:
What To Look For in Late October.

This year Halloween is the last day of Daylight Saving Time.  On Halloween night we’ll turn our clocks back to Standard Time and the next day the sun will rise at 6:49 a.m. Eastern Standard Time and set at 5:17 p.m.  Rush hour in the dark!

Spooky!

Two Orchids: Common and Rare

Winter’s not here yet so there’s still time to see fall orchids blooming in western Pennsylvania.

Yellow Ladies’ Tresses (Spiranthes ochroleuca) are relatively common.  Standing 4 to 21 inches tall, they grow in dry open habitats such as open woods, thickets or meadows and even by side of the road.  Dianne Machesney photographed the one above at Moraine State Park.

October Ladies’ Tresses (Spiranthes ovalis), below, are so rare that they’re listed as endangered in Pennsylvania. Their USDA Pennsylvania map shows them occurring only in Lancaster County.

Despite this status, Dianne and Bob Machesney found them blooming at both McConnells Mill and Moraine State Parks on 19 September 2015.

You can find October Ladies’ Tresses this month in moist, shady woods or thickets, or along the edges of marshes.  Keep your eyes peeled for a flower that’s 2 to 15 inches tall.

Two Gentians

Autumn would not be complete without a look at two gentians that bloom in western Pennsylvania from late August to October.

Bottle or closed gentian (Gentiana andrewsii) is relatively common, especially in damp shaded soil at Moraine State Park.  When the flowers bloom they remain so tightly closed that only bumblebees can force their way in and pollinate the plant.  Other insects cheat, however, and pierce the flower to reach the nectar.

Fringed gentian (Gentianopsis crinita) is such a rare plant that the Western Pennsylvania Conservancy acquired and preserved the Fringed Gentian Fen in Lawrence County to protect it.

Fens are open wetlands dominated by grasses and sedges that have pH neutral or alkaline water with lots of dissolved minerals.  Fens seem useless to humans because they’re so soggy but they’re exactly where fringed gentians love to grow.

Visit damp places in September and October to find these two gentians.

Tiny Autumn Orchid

Last Monday I attended a botanical outing that promised fall orchids including this one: Late Coralroot.

Late or Autumn Coralroot (Corallorhiza odontorhiza) is a tiny orchid that grows in eastern North America from Quebec to Texas.  Like Indian Pipe (Monotropa uniflora) it’s a parasitic plant that feeds on fungi so it has neither chlorophyll nor leaves. Most of the year it lives underground.  Then in late summer it sends up one stem to produce tiny flowers only 1/5″ long which bloom from August to October.

The stems we found in Butler County, Pennsylvania were dark purple-brown, about 8 inches tall.  From above they looked like small useless sticks but as soon as we found them we realized how easy it would be to step on one unawares. Yow.

The plant’s color and size made it difficult to photograph. Nonetheless, here are some (poor) photos to give you an idea of the plant.  Here it is as seen from ground level, though not the entire plant.

This closeup shows the flower’s white un-notched lip with purple spots.  It also shows a strange characteristic: Some flowers are rotated sideways.

When the flowers go to seed they droop along the stem.

Though abundant in the spot where we found it, this plant is listed as endangered in several states and “Exploitably Vulnerable” in New York … so I’m not revealing its location.

Confused About The Season

Last Sunday I found several ornamental trees blooming at Frick Park near the Blue Slide playground.

The branches held both flowers and green, unripe fruits.

I don’t know why they’re blooming.

Have you seen trees this month that are confused about the season?

Now Blooming: Biennial Gaura

Though the plant looks like a tall weed, this pretty flower is blooming now in fields and open areas.

As its name suggest, Biennial gaura (Gaura biennis) takes two years to bloom.  In the first year it’s a rosette of basal leaves that sends down deep roots to survive wet winters and dry summers.  In the second year it grows 4-6 feet tall and blooms in August.

The flowers are white when they bloom and turn pink as they fade.  I never notice the plant until the flowers are pink.
