Early Splashes of Autumn Color

Fall creeps up on me in the same fashion each and every year.  I notice the change in blooming wildflowers and waning sunlight in the late afternoon almost subconsciously as the days of September slip slowly towards October and our inevitable slip into winter.  Cooler temperatures mean I can once again sleep with my windows cracked to allow that crisp, chilled night air to creep in and retire my air conditioning for the season.  It all seems to happen at slow enough intervals for me to never take full notice of the changes happening until that one day where it all just clicks and I realize my beloved fall is here.

This annual moment of recognition always seems to happen to me on the same stretch of country road close to my home.  The diversity of fall wildflowers and changing fall foliage never disappoints and paints a spectacular portrait of scarlet, oranges, and golds.  It's at this time I like to leave the car behind and walk down the road to see what fall scenery awaits the camera and I.

Bottle Gentian  ~  Gentiana andrewsii

The first stop and most anticipated stretch of the road is a wet ditch that contains the unbeatable blue hues of the bottle gentian (Gentiana andrewsii).  The plants on a good year number in the hundreds but the unfortunate drought we suffered through this past year allowed only a few dozen to appear and flower but some were in prime shape and willing to show off their floral beauty.

Poison Ivy  ~  Toxicodendron radicans

It's a shame poison ivy (Toxicodendron radicans) gets the bad rap it does from so many people and is so quick to be eradicated upon discovery in anything less than a natural setting.  Personally, I love the vine and am of the opinion it has arguably the most stunning multi-colored fall foliage.  Apart from the seasonal color, poison ivy's ripened fruit supplies migrating and over-wintering birds a vital and high quality food source.  I may have been on the losing end of the plant's irritating urushiol oil countless times but it's still not enough of a reason to like this plant any less.

Virginia Creeper  ~  Parthenocissus quinquefolia

Another attractive fall native vine is Virginia creeper (Parthenocissus quinquefolia).  This is often confused with the aforementioned poison ivy which has three leaflets compared to the creeper's five.  Virginia creeper is a very common species throughout the state and is considered an unwelcome weed to some, but once again I welcome it and its foliage/sustenance capabilities.

American Hazelnut  ~  Corylus americana

All along the forest margins to either side of the road were numerous thickets of American hazelnut (Corylus americana), full of matured fruit residing in their papery husks.

New England Aster (darker purple) and Purple-stem Aster (lighter purple)

Blending nicely together against the more warm colors of the leaves were the cool blues and purples of several aster species growing along the road and forest margins.

New England Aster  ~  Symphyotrichum novae-angliae

The dark purple ray flowers of the common New England aster (Symphyotrichum novae-angliae) are sure to brighten anyone's day with their contrasting golden inner disc flowers.  It can achieve somewhat of a weedy appearance and habit but it's hard not to like or want this frequent fall wildflower around.

Purple-stemmed Aster  ~  Symphyotrichum puniceum

In the more moist sections of the roadside and ditches grew large, bushy thickets of the appropriately-named purple-stemmed aster (Symphyotrichum puniceum).  They appear somewhat similar to the New England aster but have lighter lavender ray flowers and a purple, pubescent stem.  A couple photos above shows just how nicely the two species can mesh when growing side by side.

Yellow Buckeye  ~  Aesculus flava

One of the earliest woody plant species to lose its leaves each year is the yellow buckeye (Aesculus flava), which also happens to be one of the first plants to leaf out every early spring.  Their fall color leaves much to be desired but its branches can still draw some attention for the large, smooth, and leathery husks containing the well-known buckeye nut.

Large-leaved Aster  ~  Eurybia macrophylla

Scattered in the wood's lower slopes was one of my favorite species of Asteraceae, the large-leaved aster (Eurybia macrophylla).  The pale lavender flower heads arise from the large basal leaves come fall and add a soft touch of color to the forest.  Large colonies of plants can act as an attractive ground cover with their basal leaves that are quite obvious and noticeable when making an ID.

Chinese Chestnut  ~  Castanea mollissima

One of the most surprising discoveries along my country road is a mature, flowering/fruiting chestnut tree!  Alas, don't get too excited as my suspicions were quickly confirmed when I felt the wooly undersides of the leaves and new growth twigs.  This is a Chinese chestnut (Castanea mollissima), which is strikingly similar to our native American species (C. dentata) but differs in having its new growth covered in wooly hairs while our species is completely smooth (glabrous).  Regardless it was still neat to see a chestnut tree packed full of its tennis ball sized spiky fruits.

Musclewood  ~  Carpinus caroliniana

The musclewood (Carpinus carolinana) leaves were beginning to show signs of changing as photosynthesis shuts down and chlorophyll drains from the leaves.

Shagbark Hickory  ~  Carya ovata

It wouldn't truly be fall without the sound of walnuts, acorns, and hickory nuts falling from their limbs and branches to the ground below.  Fruit production among the oaks and hickories seems to have had a good year as I've seen many trees loaded with nuts; excellent news for the numerous woodland critters that will need some over-wintering sustenance.

Spicebush  ~  Lindera benzoin

The brilliant mature red drupes of the spicebush (Lindera benzoin) rarely linger on the shrubs come fall as the migrating birds are desperate to build up their fat reserves for the long flight south.  Spicebush berries are considered one of the best high-quality fruits for their high lipid (fat) content and can go a long way in powering a one-to-two ounce bird to central and South America.

I hope to bring more of southeastern Ohio's gorgeous fall scenery and wildflowers to the computer screen as the season wanes.  Let's hope this recent rain and some renewed sunny days combined with clear, cool nights will allow this fall's peak foliage show to not be a bust as the spring and summer's drought would suggest is likely.

The Yellowish and Bottle Gentians


I decided for my first post to take a look at two of my favorite fall blooming plants that come from a family well known for their unique beauty, the Gentians, Gentianaceae.   Click the photo's to see them in their original size for better quality and detail!

Gentiana alba
Gentiana alba




















One of the first Gentians to bloom in Ohio is the Yellowish Gentian, Gentiana alba.  Also known as Cream or Plain Gentian, it is listed as a threatened species in the state of Ohio only being currently found in Adams and Athens counties according to the Ohio Department of Natural Resources (ODNR).  I came across this species on the diverse and botanical wonderland that is the Edge of Appalachia preserve in Adams County, OH.  The flowers look like small, white, football shaped tubes but are actually 5 petals that hardly open when they are in full bloom.  The photograph above shows how tightly these 5 petal tips are wound.  As the flowers mature the tips loosen just enough to allow this plants chief pollinator, the bumblebee, to pry apart the petals to access its nectar reward and in the process pick up and deposit pollen, thus pollinating the flower.  The photographs below are an example of nearly mature blooms just starting to open.

The Yellowish Gentian resides in mesic prairies, savannas, grassy meadows and damp woods; which is where I found this particular population.  A small seep from the side of the hill has allowed these plants to continuously receive the amount of moisture they need to survive.  However with the natural progression and succession of nature in the forest opening these plants are at risk.  Without management of this spot; such as clearing the understory and opening the canopy so these plants can receive their high quota of sunlight, these very rare and beautiful plants will disappear.  Even more reason to manage this spot is the presence of two potentially threatened species: Tall Larkspur, Delphinium exaltatum and Lesser Ladies-tresses, Spiranthes ovalis, which I plan to discuss on a post in the future.   That's three rare, state listed species all within a few feet of each other, a very good reason to give this area some attention!


Gentiana andrewsii
The next species of Gentian is essentially a purplish blue version of the aforementioned Yellowish Gentian and shares some of its habits.  Bottle Gentian, Gentiana andrewsii, is a gorgeous fall bloomer that is found in high quality wetland areas such as moist prairies and forest openings, fens, moist thickets and swampy areas near bodies of water.  Funnily enough I stumbled across a large colony off it in full bloom in a wet ditch along my road in Athens county, a welcome surprise!

These plants stand 1-2 feet tall at maturity and produce flower buds at the top of the stem as well as in the leaf axils on the upper sets of leaves.  The flowers in the pictures are fully matured and are never seen open, hence their common name.  Similar to the Yellowish Gentian, the Bottle Gentian has 5 petals whose tips are closed at the end.  The inside of the flower structure exhibits the tiny fringing on the tips of the 5 petals as well as the stamens and pistil.  Normally the stamens are up tight against the pistil but upon opening of the flower I caused them to spread out.  The dark blue vertical lines on the inside of the petals serve as nectar guides for the pollinating bumblebees.  The bees see them through the outside of the flower and know that inside lies a nutritious meal.  The following photographs show the process of the bumblebee forcing his way inside the flower which was fascinating to watch in person.  I found a comfortable spot to sit and waited patiently for a bumblebee to buzz close enough to my lens to capture his fascinating task.  As the bumblebee breaks into the flower he disappears inside to collect his prize and upon satisfaction backs up and slides out of the flower and continues on to the next.







Many people complain about all the annoying, biting and stinging flying insects in nature and wish the world was rid of them.  How regretful and sorry those people would be if their desire came to fruition.  Without the bumblebees evolved relationship with the Bottle Gentian this plant would cease to exist and the bumblebee would be without a major food source.  Such inter-relationships are vitally important to just about all flowering plants and the countless numbers of insects.  Without those bothersome six legged fliers our world would be a much more bleak, barren and hungry place.

I hope you have enjoyed my first post and look forward to the many, many more to come covering all kinds of different flora and fauna!  If along my journey I can get just one person to care and become interested in our natural world and the conservation, preservation and protection of it then I will have done my job.  After all we are all just one person and look at the differences we, you can make!
