Late September Wildflowers

Except for very late bloomers like witch hazel, late September is really more about which flowers are still blooming rather than which are just starting. Spotted touch-me-not (Impatiens capensis) is a good example of flowers that will bloom right up until a good frost. As day length shortens the plants will produce smaller, closed flowers with no petals and no nectar. They self-pollinate and their sole purpose is to produce plenty of seeds.

When spotted touch-me-not flowers first open they are male, but then change to female. The way to tell is by looking for white pollen. If white pollen is present the flower is male. Female flowers will have a small green pistil in place of the pollen seen in this photo.

I used to think that black eyed Susan’s (Rudbeckia hirta) were the longest blooming of any wildflower but once I started paying attention I found that wasn’t true. But it is a marathoner rather than a sprinter and can bloom from June right up until a hard frost.

This plant was always believed to have been given its common name by English colonists, but that caused a real conundrum among botanists who all agreed that it was a prairie native. Though everyone still agrees that it is a prairie native, recent research has shown that it was growing in Maryland in the 1600s. In other words it was most likely growing in all parts of the country then, just as it does today. I can’t understand why botanists thought that a prairie native would simply stay there. Why wouldn’t it have spread far and wide, just like plants do today?

Knapweed is terribly invasive and hated by pasture owners but even though I know all of that its flowers win me over every time. This was one of just a few left in a large group of plants that had all withered and turned brown.

I was surprised to see this mullein (Verbascum thapsus) plant blooming so late in the year. I wonder if it will have time to set seeds. Mullein is a biennial and flowers and dies in its second year of growth. It is considered a weed but if all of its flowers opened at once along its tall flower stalk it would be a prized garden specimen.

By the time I got to the spot along the Ashuelot River in Gilsum where big leaf asters (Eurybia macrophylla) grow they had almost all gone by, but I did find one or two that were still hanging on. The big leaves on this plant are very different from other asters, so it’s a hard plant to misidentify.

This plant taught me a good lesson; the photo I took of it last year was chosen by the State of Georgia for inclusion in its new wildflower guide because it showed both the flowers and leaves, so if you think that you might like to sell your wildflower photos try to include some foliage whenever possible.

Even phlox, a plant known for its late bloom period, has almost gone by now. There are many varieties of phlox but I think the one pictured is Phlox paniculata, which is native to the eastern United States.

Arrow leaved tear thumb (Polygonum sagittatum) has small tufts of pinkish white flowers at the ends of long, weak stems. It is usually found sprawling on and around other stronger stemmed plants that help support it. It loves to grow near water.

The reddish, 4 sided stems of arrow leaved tearthumb have tiny, backward pointing prickles that the plant uses to hang onto other plants when it crawls over them in search of more sunlight. These prickles are plenty sharp enough to tear into the flesh of your thumb (or any other body part) if you try to pull at the plant without gloves on, and that’s where the common name comes from.

Common yarrow (Achillea millefolium) has a period of bloom in June through August and then rests for a while before giving it another go.  Mankind has had a relationship with this plant since before recorded history and dried sprigs of it have been found in Neanderthal graves. The ancient Greeks used it on wounds to staunch blood flow and so did Native Americans.

According to the book The History and Folklore of North American Wildflowers by Timothy Coffey, in England if a boy put a sprig of yarrow in his nostril and twisted it around three times and got a nosebleed, he was sure to win his sweetheart. It is said that the boys in Suffolk call the plant green ‘arrow and recite the following rhyme:

Green ‘arrow, green ‘arrow you bears a white blow;
If my love love me, my nose will bleed now;
If my love don’t love me, it won’t bleed a drop;
If my love do love me, ‘twill bleed every drop.

I know that this purple morning glory (Ipomoea purpurea) isn’t a wild flower but I had to sneak it in because of the amazing light that seemed to be shining from it.

Autumn asks that we prepare for the future —that we be wise in the ways of garnering and keeping. But it also asks that we learn to let go—to acknowledge the beauty of sparseness. ~Bonaro W. Overstreet
