Autumn Wildflowers of August and September.

September 3, 2016

Late summer brings about another change in the wildflowers to be seen here in Ohio.  Early autumn is the last hurrah of plants before the cold season sets in.

August ushers in a variety of colorful plants.

Various sunflowers (generally lumped under their genus name Helianthus) grace wood edges

Coneflowers, such as this Green-Headed Coneflower, are also notable

Wingstem is prominent along paths in woods and in shaded clearings

0916 (10)

Evening Primrose makes its seasonal appearance in waste spaces

0916 (14)

Great Lobelia can be seen in shaded areas

Thistles stand out with their colorful flower heads surrounded by spines

0916 (11)

Ironweed, tall and purple, is a stand-out plant

0916 (18)

Lady’s Thumb, also known as Knotweed, is a prominent ‘weed’

0916 (24)

Ragweed- the source of many allergies

As the year advances into early autumn, September brings with it other bursts of color to add to the mix.

Snakeroot can be found along paths in the woods and wood edges

Thoroughwort looks somewhat like a white version of Ironweed

Jerusalem Artichoke is a late sunflower, very tall and noticeable in prairie areas and brushy wood borders


Meanwhile, in the woods, some hidden wildflowers bloom- many understated, although not all are that way.

Wood Nettle has barely-noticeable green blooms along its stems

0916 (17)

Jumpseed has curious small white blooms along its stems- other types of plants like this are Lopseed and Enchanter’s Nightshade

0916 (9)

Jewelweed, with its orange and yellow exotic blooms, bring the most color to woodlands this season

0916 (19)

Leafcup has very understated pale yellow blossoms nearly hidden by large ragged leaves

0916 (16)

Joepyeweed can be found both in the woods and near its edges, attracting many birds

Finally, September sees the massive presence of two widespread types of wildflowers that almost define autumn.

Goldenrod is very abundant in fields- see more here

0916 (1)

Asters are also abundant- much more can be seen here

Early autumn’s wildflowers linger into October and then dwindle as winter’s shorter days and colder temperatures signal the end of another growing year.  We’ll be happy to see wildflowers return once more next spring.

    I grew up with the idea of “spring wildflowers” as if all other seasons were omitted, glad to find out that wasn’t the case!

      So true- there’s some very interesting wildflowers out there late in the season, Robert & Donna!

    Such great names – wing stem, jump seed, lady’s thumb! Would be the basis for a great poem.

      Very true, Jane- I like how the early settlers were very comparative in their thinking when naming such things!

    A visual feast. Thank you.

    I’ll have to go out and see how many of these I can spot here. Do you know if the Jerusalem Artichoke is the same as the food plant?

      I’m not 100% sure but I think so, Inger- some wild plants have cultivated garden versions 🙂
