September is the season where wildflowers get more colorful right before the trees get brighter colors of their own- the year is moving rapidly (too rapidly, some say) towards its conclusion.  I’ll start off with this month’s prominent blooms, as usual:


This is the clear winner in the sheer numbers category!


Asters got off to a slower start than Goldenrod, but they’re blooming in large numbers now.


This plant is numerous along wood borders and treelines, it seems to like some shade.  It showed up in smaller numbers in August, but there’s a lot of it blooming now, and some are already turning brown.


Very common in weedy places.  It’s one of those plants that I never catch blooming and seems to go right to fuzzy seeds!

Queen Anne’s Lace

Along with Chicory, this abundant summer plant is still around, though browning and forming ‘birds nests’ more and more.


Greater Ragweed

Lesser Ragweed

The Ragweeds are quite common, as hay fever sufferers know.  Goldenrod gets the rap for pollen allergies, but Ragweeds are the usual culprits.

Lady’s Thumb

Colonies of this interesting plant like the shade of wood edges.


Generic Sunflowers are still around too.  It’s often a headache to tell the specific species apart because they hybridize as well as look very similar to begin with.

Hairy Sunflower

Its cheerfully bright yellow bloom can still be found in prairies and fields.

Three-Lobed Coneflower

The latest reliably blooming Coneflower species in the area.  Gray-Headed, Green-Headed and Purple Coneflowers are mostly browning by this month.

Tickseed Sunflower

The latest blooming sunflower that I typically see.

Evening Primrose

High on the list of my favorite autumn wildflowers.


Often browning by now, there’s still a good amount of richly-colored blooms left.

Curly Dock

Birds like this plant’s seeds.

Common Teasel

A lot of this is brown by now, but I still see the occasional bloom.

Great Lobelia

A handsome plant occasionally seen along greenways or wood edges.


Thoroughwort is an interesting autumn plant.  I usually see it in dry fields.  It may be confused with Boneset, but its leaves are narrow and not joined at the stem like Boneset, which likes moist soil anyways.


Still seen in wet areas.


Common last month, it’s mostly lost its blooms by the end of this month.

Birds-Foot Trefoil

Less common than it was last summer, but still handsome.

Obedient Plant

This striking plant doesn’t mind early autumn.

Biennial Guara

This different wildflower is almost done blooming now.

Water Horehound

This uncommon plant is fading, too.  I’ve seen more of it seeding than blooming.

Cat tail

The last of the blooming wetlands plants, it is starting to seed and grow fuzzy.

Wood Nettle

This woodland plant is starting to fade.  It had a rough year in drought conditions.


Another fading woodland plant.  Note its hook-like blooms.

And there are still some of those familiar lawn-friendly plants around, in lesser numbers:

Red Clover

White Clover


Common Plantain

English Plantain

Wood Sorrel

And to wrap things up, here’s a browning plant.  Brown blooms are increasingly becoming more common in early autumn.

This Self-Heal is done blooming and is seeding now.  My favorite late summer plant- Ironweed- shares the same fate.  Fields and roadsides will show increasing amounts of this drab color in the coming months, as the warm weather becomes a sunny memory.
