Autumn Morning: Prairie Remnant Exploration

DSCF5782

This past Sunday morning, I took a walk to a prairie remnant near my home.  Somehow, it escaped the plow and other development to still be with us today – very unusual in this part of Chicagoland.  At one time this ten acre parcel was part of a golf course, subdivided into tiny lots – but never “improved” with roads, etc.  At one point, the land went into tax default and subsequently up for auction.  The adjacent town of Crete purchased the property and wanted to annex the unincorporated land in to their town.  Crete’s neighbor, the town of Steger said that it was already part of their town, so bugger off Crete.  The Great Recession of 2008 caused a detente over rights to this taxable plot of land, which is one reason it still is open land, full of bird life and a rare example of prairie plant and fauna biodiversity. 

On one of my walks, I saw a rare green Grass Snake – not much bigger than a pencil.  Pretty cool, and so is the prairie remnant.  Maybe Crete and Steger will realize, one day, that its best use would be as preserved green space, not houses, not a strip mall, and not green space as in ball fields either – a park can be more than ball fields and play equipment – in this case it could be a place for adventure, learning, and relaxing.

So while we still can, let’s enjoy the rare beauty of the Midwestern landscape:

The Uncommon Unexpected Cycnia

Larva found in my backyard meadow

Unexpected Tiger Moth larva, with its gray tufts and orange skin, found in my backyard meadow

While taking a walk around my backyard meadow (in southern Cook County, Illinois) the other day, I came across a larva (caterpillar) that I haven’t seen before.  I was checking my Swamp Milkweeds (Asclepias incarnata) for Monarch larva, when I saw this frightful fella, the Unexpected Tiger Moth larva.  Their appearance warns predators that making them a meal would be an unpleasant experience.  The larva only feed on native milkweeds primarily A. tuberosa, Orange Milkweed, A. verticillata, Whorled Milkweed – the larva take in alkaloids from the milkweed plants, making them unpalatable.  The small white Unexpected Tiger Moth is considered uncommon and rare, so I am especially excited to have found it in my backyard meadow, which was mowed lawn previous to 2006. 

According to a conservation assessment conducted by the USDA Forest Service (found here), this moth prefers oak barrens and their associated grasslands.  They do not migrate as Monarchs do, rather, they overwinter locally in cocoons.  This makes them sensitive to fire management.  These moths are so uncommon, that a single fire can wipe out a local population, and some states only have one known population.

So I while I still have not found any Monarch larva on my milkweeds, I did discover something equally, if not more, interesting on my evening walk!

The Backyard Meadow – Mid-Summer Blooms and Bugs

455

The meadow in my backyard is getting better every year.  In 2006, just after I moved in, this area was mowed on a weekly basis.  I could see, though, that this area was never planted to turf, like the areas closer to the house.  There were Pussy Toes blooming in spring, asters, Poverty Oats Grass, Wild Strawberries, and other things just waiting it out – for about 50 years, until I came along.  I stopped mowing, herbicided the weeds, and seeded in and planted native tallgrass prairie species.


This past week, the Prairie Blazing Star (Liatris pycnostachya) started blooming.  In the photo above, it is blooming with the white flowered Wild Quinine (Parthenocissus quinquefolia) and on the right edge of the photo, Rattlesnake Master (Eryngium yuccifolium) with its strappy, yucca-like leaves.  In a few weeks, another blazing star in the meadow will be blooming, Rough Blazing Star (L. aspera).

363

Almost all of the white in this photo below, is Mountain Mint (Pycnanthemum tenuifolium) mixed into a matrix of Little Bluestem Grass (Schizachyrium scoparium).  The tall yellow flowers in the distance are Gray-Headed Coneflowers (Ritibida pinata).  Walking through the Mountain Mint is a sensory experience – on a warm summer day, the clean mint smell will rise around you.

Little Bluestem Grass really puts on a show in fall, when the blue-green foliage turns a coppery orange, and stays nice throughout the winter.  Even in summer, however, it is an attractive grass, growing to 18 inches high and wide, and a bit taller when it is in flower.

443

Walking through the meadow, some pretty interesting pollinators were seen, including this Buckeye Butterfly.

522

Another visitor to the meadow was this Dragonfly, busy sunning itself on a dry twig. 

510

Gray-Headed Coneflower, Wild Quinine, and Prairie Dropseed Grass make for an eye pleasing combination.

505

Purple Prairie Clover is just about to finish it’s bloom cycle, starting from the bottom up, just the opposite of the blazing star.

The Wild Sweet Potato (Ipomoea pandurata) was rambling over the Buttonbush (Cephalanthus occidentalis).  Wild Sweet Potato grows from a large, underground tuber, as you may have guessed from its name.  Its vines grow quite a long length in a short time, dying back to the ground each winter.  The plant does not spread by roots or seeds, making it a good garden plant, as well.

491

The large white 3 to 4 inch blooms last only a day each.

486

Marsh Milkweed (Asclepias incarnata)- shown below- can get 3 to 4 feet tall and wide, sometimes that’s a bit too big for the home garden.  Purple Milkweed (A. purpuranscens) is more upright with a less open habit, but similar purple-pink flowers – a better garden plant than Marsh Milkweed.

481

Gray-Headed Coneflower at the rear of the meadow enjoys its sunny location.  Its bright yellow flowers, on 4 foot tall (or more) stalks, can be seen from a long distance away.

479

On the much shorter side of things (at approximately a foot tall), Partridge Pea (Cassia fasciculata) and the purple flowered Heal-All (Prunella vulgaris) seem to be getting along together, just fine.  Partridge Pea generally can be found in colonies while Heal-All is often found singly, and seemingly randomly, throughout an area.

474

Ironweed (Vernonia fasciculata) has just begun to show some color – with all the yellow flowers in the meadow, this bright royal purple is a welcome addition to the color palette.   At 5 feet tall, or more, the flowers can not hardly be missed.

472

The delicate looking, but quite tough, Flowering Spurge (Euphorbia corollata) makes a great accent plant, and is wonderfully adaptable in the garden, as well as being quite nice here in the meadow.  It can take part sun and damp soil, to full sun and dry ground.  It has a coarse root system that helps in this durability.

470

It would look great in any garden – with similar flowering heights, it works well planted with Pale Purple Coneflower (Echinacea pallida).  As the coneflowers wane and only the dark seed heads remain, the euphorbia comes on strong, and complements the coarseness of the coneflower.

467

The Orange Milkweed (Asclepias tuberosa) likes full sun and good drainage. It can be slow to get established, but puts on a great show.  A terrific garden plant as well.   Its coarse root system can make it a little more difficult to dig and move in the garden, but it can be done, if necessary.  Of course butterflies are attracted to milkweeds and Monarchs rely on them to reproduce.

464

Cup Plant (Silphium perfoliatum) has a great coarse leaves – big and bold, among more modest foliage.  The 3 inch bright yellow blooms provide nectar to a host of pollinators.

494

Cup Plant is true to its name, by holding water at the base if its leaves.  Insects and birds will come to drink.  And later the birds will fight for the oil rich seeds.

496

All the flowers and grasses find and make space so that they can put on their best show.  The variety of colors and shapes boggles the mind in their diversity.  Who could possibly want a lawn of monotony?

459

The meadow is a colorful place at all times of the year, even in winter with shades of orange, rust, and gold, but summer is simply amazing, not only for the flowers, but all the forms of life that take advantage of the flowers and leaves, seeds and nectar, shelter and perch. Magic … seemingly anyhow.
