XENIA through CEDARVILLE to SOUTH CHARLESTON, OHIO
A Key to Common Wildflowers in September
John E. Silvius, Professor of Biology
Thankfully, the Ohio to Erie Trail stretching from Xenia through Cedarville to South Charleston, Ohio is graced with many beautiful wildflowers. Some are remnants of the pre-settlement days when Greene County was covered with both forest and prairie lands. Most of the photos accessable from the links below were taken along the bikeway between Xenia and South Charleston, OH. Between Cedarville and South Charleston, a long segment of the bikeway is located adjacent to U.S. Route 42. Between the highway and the bikeway, a narrow strip of unplowed land exists which has been a refuge for prairie species which have been largely driven from surrounding agricultural land. The Ohio Department of Transportation (ODOT) of Greene and Clark Counties have been kind enough to erect "Do Not Mow or Spray" signs and are cooperating in a mowing program that avoids the summer months when prairie grasses and forbs are actively growing and storing reserves for winter and the next growing season. To learn more, you have two choices as shown below:
1. Visit our remnant prairie plant page to view some of the more rare prairie plant species that are being protected through cooperation between the Greene Co. and Clark Co. Park Districts, the ODOT, the Dayton Power and Light Company, and adjacent landowners.
2. Use the Wildflower Key below
to Get Acquainted with Common Wildflowers -- Stop
along the way, being careful of passing cyclists, identify and enjoy their
beauty, and then leave them for others to enjoy. More serious "biking
botanists" may wish to obtain a wildflower guide at a library or bookstore.
To Use This Guide:
Observe the plant, then decide
which of the following categories your plant represents. Go to the appropriate
"Key" as directed:
I. Wildflower -- Includes
species with colorful flowers. They are not woody like
trees or shrubs.
Go to "Wildflower Key" below:
II. Grasses -- Includes species
with grass-like leaves, topped with many tiny
flowers arranged in delicate sprays.
Go to "Grass Key" below:

A. Flowers White or Whitish:
1. Flowers
Large -- ½ inch or more in length or diameter; petals can be
easily counted.
Bouncing Bet (Saponaria officinalis) 1
If flowers are not so, go to "2."
below.
2. Flowers Small - less than ½ inch;
hard to count petals
a. Flowers in flat lacy heads -- Queen Anne's
Lace; Wild Carrot (Daucus carota)
b. Flowers numerous, in a flattened cluster as if the plants are covered
with snow;
consider the following choices
Leaves egg shaped (oval) - White Snakeroot, (Ageratina altissima or Eupatorium rugosum) 1;
prefers shaded upland
sites
Leaves narrow, tapering at both ends - Tall
Boneset, (Eupatorium altissimum);
prefers sunny upland sites
Leaves wide, pierced by the stem - Boneset
(Eupatorium
perfoliatum); moist sites
(e.g. just E of Rt. 35)
B. Flowers Green, Arranged in Pointy, Finger-Like 'Spikes':
1. Plants tall (3 to 15 ft); leaves divided into 3 lobes - Giant Ragweed (Ambrosia trifida)
2. Plants short (< 3 ft), finely divided leaves - Common Ragweed, (Ambrosia
artimesiifolia) Note: Ragweeds are the
chief cause of pollen allergies in
late summer,
not goldenrods.
C. Flowers Orange or Yellow:
1. Flowers sunflower-like -- a central disk or knob composed of
many tiny flowers
surrounded by a circle of "rays" which appear to be petals
but are each flowers with an elongated "petal-like" corolla
a. Rays drooping downward away from disk (center):
Disk made of loosely arranged flowers; wings or ridges run down stem --
Wingstem(Actinomeris alternifolia)
Disk cone-shaped; rays yellowish; leaves large, divided into leaflets --Tall
Coneflower (Rudbeckia laciniata)
Disk an elongated, gray or brown knob, anise-scented --
Gray-headed
Coneflower (Ratibida pinnata)
b. Rays not drooping downward away from disk (center):
Both disk (center) and rays are yellow or orange; opposite leaves --
Sunflowers
(Helianthus) 3
Disk (center) is much darker (blackish-brown) than rays --
Black-eyed
Susan (Rudbeckia hirta)
Flowers on tall, leafless stalks; large basal leaves --
Compass
Plant (Silphium laciniatum)
2. Flowers dangling, slipper-like, tapering to a slender spur:
Flowers Orange -- Spotted Touch-me-not (Impatiens capensis) 3
Flowers Yellow -- Pale
Touch-Me-Not (Impatiens palida) 3
3. Flowers with four petals, opening at twilight; conspicuous pods
(fruits)
-- Evening Primrose (Oenothera sp.)
4. Numerous Tiny Flowers forming several branching clusters; prominent
in September
landscape -- Goldenrods (Solidago)
4
D.
Flowers Violet or Purple, numerous, forming a flattened cluster;
plants tall,
common in pastures - Ironweed (Vernonia
sp.)
E.
Flowers Blue:
1. Sunflower-like heads and toothed, blue rays; borne
on leafless stems; close up in the heat
of the day -Chicory (Cicorium intybus) 5
2. Flowers star-shaped, arranged on tall spikes; prefers shady areas:
Tall
Bellflower
(Campanula americana) -- Habitat
view and Close-up View
3. Flowers tubular, snapdragon-like, with stripes beneath, in moist
areas - Great Lobelia
(Lobelia siphilitica)
F. No
Flowers: Bamboo-like stems, <½ inch diameter,
damp, sandy areas
(e.g. between Bicket Rd. and U.S. 35.) - Scouring
Rush - Equisetum hyemale) 6

Grasses are a prominent and beautiful part of the Autumn bike trail landscape. Their flowers are born in tight, wheat-like spikes or racemes, or in delicate open-branched arrangements called panicles. Two beautiful grasses are Big Bluestem, a key member of the tallgrass prairie; and, Indian Grass. Both species can be found in Greene Co. as a remnant of the original prairie landscape which occupied parts of southwest Ohio. Because railroad right-of-ways were not plowed, but did experience occasional fires, these species found refuge from the plow which eliminated their kind in adjacent farm fields. Agricultural "weed grasses" are also present along the trail-- e.g Foxtail (Setaria). Use the following key to get acquainted:
A. Flowers in a Wheat-Like Head; many bristles - Foxtail (Setaria)
B. Flowers in open "panicles":
1. Reddish
gold colored panicles; "rabbit-ears" visible where leaf blade joins
the stem -
Indian Grass (Sorghastrum nutans)7
2. Dark purple panicles, oily to the touch - Redtop, Purpletop (Triodia flava)
C. Flowers
in 3-part racemes resembling a turkey foot; growing in bunches
-- Big Bluestem (Andropogon gerardii) 7
