More Early September Flowers

New England asters (Symphyotrichum novae-angliae) continue to bloom heavily in spite of the drought. This plant was growing in a dried up streambed and was doing well. Something I’ve learned about them over the years is that they’ll grow and bloom in shade, as this one was.

A New England aster flower is made up of many petal like ray flowers around the outer perimeter and disc flowers in the center. The disc flowers are sometimes called tube flowers because of their shape. At about an inch across they are the largest flower heads found on any of our asters but this year I’ve noticed they’re a bit smaller, probably due to stress from the drought. The Native American word for this plant is said to have meant “It brings the fall.” They used the plant medicinally to relieve many ailments, including pain and fever.

Brown knapweed (Centaurea jacea) has grown back and is blooming again after being mowed down.  This European plant, according to the U.S. Forest Service, is a “highly invasive weed that is capable of forming large infestations under favorable conditions.”  The large infestations crowd out native plants including those used for forage on pasture lands, so it is not well liked by ranchers. The brown bracts below the flower are what give the plant its common name.

I’ve always thought that knapweed flowers were very beautiful. Here the plant is planted intentionally along with other invasives like crown vetch to stabilize hillsides. I’m not sure how we can complain about a plant being invasive when we are planting it along our roadsides.

And here was crown vetch (Securigera varia) growing right along with the knapweed. Some flowers seem to have a little extra spark of life that makes me want to kneel before them and get to know them a little better, and one of those is crown vetch. It’s very beautiful.

Black eyed Susans (Rudbeckia) are still blossoming but not as they usually do. I didn’t think anything could bother such a tough plant but apparently they do not like dryness. Theses examples grew in the shade and didn’t look quite as ragged as many I’ve seen. The Native American Chippewa tribe used this plant to treat snakebite and colds. The roots were used to rid the body of worms.

I saw this plant in a local garden and I wasn’t sure what to say about it. Though the flowers reminded me somewhat of a black eyed Susan the petals seemed strangely tubular. Luckily it was easy to find online. It is indeed a black eyed Susan called “Henry Eilers.” I’ve read that it is a “standout among black eyed Susans,” and I would guess that would be true.

Datura (Datura stramonium) is in the nightshade family and all parts of the plant are toxic to humans and livestock. Taken in small enough doses the plant is hallucinogenic, as British soldiers found out when they included Jimsonweed leaves in salad in Jamestown, Virginia in 1676. They were high for 11 days and had to be penned up to prevent them from hurting themselves. When the symptoms wore off they remembered nothing. You can read about the incident by clicking here. I can’t say that it sounds like a good time.

Datura has many common names, one of which is thorn apple. The unripe seed pod in this photo shows how that name came about.

Bog asters (Oclemena nemoralis) grew in standing water at the shoreline of a local pond. The small, sword shaped leaves had no stems (petioles) and each unbranched stem grew to about a foot tall with a single, light purple flower at its tip.

Because bog asters usually grows in thickets in wet, swampy areas many people never see them. They grow all around the shore of this pond in great numbers but this is the only place I’ve ever seen them. Each flower is about half the size of a New England aster.

Dandelions always warn me that the weather is going to turn cooler because they don’t like hot weather. I didn’t realize it until I started watching them closely for this blog but they bloom heavily in spring and then disappear in the hottest months, and then re-appear when it cools off in the fall. This is one of the first I’ve seen since June.

As flowers go Canada horseweed (Conyza canadensis) isn’t much to look at. The flowers are tiny and seem to stay closed more than they do open. This club shaped plant can be easily seen from a distance because it starts branching at about a foot or so down from the tip of the tall, 3 foot stem and always looks top heavy. This plant is a North American native but is considered a noxious weed over much of the world. Legend has it that dried horseweed stem is one of the best materials for a drill when making fire with friction. Its stems are weak, so rubbing it between your hands rather than using a bow is recommended. It is said to produce a glowing coal with very little effort.

You’d never know it by looking at the tiny flowers but horseweed is in the aster family. Each flower is smaller in diameter than a pencil eraser and it’s hard to catch them in bloom.

What I believe were smooth blue asters (Aster laevis) grew on a roadside. These small plants were most likely second growth because the roadside had been mowed, so it’s hard to tell what their maximum height would be but the blue green foliage, lack of hairs on the leaves and stems, smallish 1 inch flowers, and lack of leaf petioles all point to the smooth blue aster. Also, the plants grow as a single stalk for part of their height before branching, and that’s another identifying characteristic. What bothers me about saying definitely that is what they are however, is my color finding software. In this flower it sees blue and purple…

…and in this flower it sees purple. I know that flowers can be called blue when they’re really purple, like blue vervain for instance, but I’d like to see these plants again next year to be sure, preferably before they’ve been mowed.

I’m waiting for the darker purple asters to appear but so far all I’ve seen is this one in a garden. They’re my favorite colors for an aster but they aren’t as common as the lighter colors.

I like this cosmos with frosted edges I saw in a garden.

White rattlesnake root (Prenanthes alba) still blooms, and is having the best year that I can remember. It must like dryness. I can’t think of another plant that has small, drooping white, lily like blossoms at this time of year. The half inch flowers appear in clusters at the end of branched stems that can reach 5 or 6 feet in some cases, and have forked stamens that are longer than the petals, as these examples show. The plant gets its common name from the Native American belief that it could cure rattlesnake bites.

There is white rattlesnake root and then there is white snakeroot (Ageratina altissima,) and of the two snakeroot is the one to be careful with. This plant is very toxic because of a compound called tremetol, which is passed from the plant to cows that graze on it. These days dairymen mix the milk from many cows and make sure this and other toxic plants are removed from their pastures so there is little chance of the plant having any real impact, but in days past if humans drank the milk or ate the meat of cows that had eaten this plant they could come down with what was once called “milk sickness.” The sickness caused heart or liver failure and Abraham Lincoln’s mother is believed to have died from it.

Though its flowers resemble those of boneset, which flowers at the same time, white snakeroot’s  large heart shaped, toothed leaves look nothing like boneset leaves. All parts of the plant are toxic to cattle, horses, sheep, and humans.

A sunflower turned its back to the sun. According to an article on National Public Radio scientists have found that once sunflowers mature they stop following the sun and face east. When young they greet the sunrise in the east and then as the day progresses they follow it to the west until it sets. During the night time they slowly turn back to the east to again to wait for the next sunrise. They do this through a process called heliotropism, which scientists say can be explained by circadian rhythms, a 24 hour internal clock that humans also have. The plant actually turns itself by having different sides of its stem elongate at different times. Growth rates on the east side of the stem are high during the day and low at night. On the west side of the stem the growth rate is high at night and low during the day, and the differing growth rates turn the plant. Since this one was not facing into the sun I’d say it has matured.

Early September Flowers

We’re almost at that point of peak flower production now as this view across a stream shows. Goldenrod, tall asters, Joe Pye weed, boneset, and purple loosestrife can all be seen here. We’re still waiting on New England asters but it shouldn’t be long.

The funny little plants called false dandelion (Hypochaeris radicata) have appeared in force and I’m seeing them everywhere. This plant gets its name from its resemblance to the dandelion, but it would be hard to mistake one for the other. The flowers are about half the size of a true dandelion and they bob around on long, wiry stems. At a glance you might think you were seeing a hawkweed flower when you look at a false dandelion flower because they’re close to the same size. One look at the leaves however, will show you that you’re seeing something entirely different because they resemble those of the dandelion more than hawkweed foliage. Hawkweed and false dandelion also bloom at different times, which helps when trying to identify them.

False dandelion leaves look like miniature versions of dandelion leaves and are nowhere near as wide or as long.

White wood asters (Aster divaricatus) lined a woodland path and made a pretty walk even prettier.

I always find silverrod in dry, gravelly places at the edge of the woods near the end of August. It’s hard to get a photo of because it’s usually surrounded by other plants and rarely grows alone. It grows about knee high and isn’t seen anywhere near as often as the yellow goldenrods.

I think almost everyone knows what goldenrod looks like but not everyone has seen silverrod. Silverrod (Solidago bicolor) is in the goldenrod family and is also called white goldenrod. It is the only native white flowered goldenrod found in the northeast. The small flowers spiral up the stem and open from the top down.

Tansy (Tanacetum vulgare) is a European native that has been cultivated for centuries, even grown in the herb gardens of Charlemagne. It was brought from England by early colonists and by 1785 it had naturalized in New England. The flat flower heads are made up of many button like disc flowers; almost like a daisy without the white ray flowers that we call petals. Tansy is a natural insect repellent and has historically been used as such. Dried tansy added to the straw in mattresses was said to keep bedbugs away. I rarely see it in nature but it can still be occasionally found growing along roadsides. It’s a good plant to use in vegetable gardens for pest control. The ancient Greeks grew tansy for medicinal use but modern science has found it to be toxic.

White rattlesnake root (Prenanthes alba) can be tough to identify because even plants growing side by side can have differently shaped leaves, but once they bloom identification becomes much easier. I can’t think of another plant that has small, drooping white, lily like blossoms at this time of year. The half inch flowers appear in clusters at the end of branched stems that can reach 5 or 6 feet in some cases, and have forked stamens that are longer than the petals. The plant gets its common name from the Native American belief that it could cure rattlesnake bites.

I saw a hosta recently in a park that was just another plain green unremarkable plant, but the reason I’m showing it here is because of its huge white flowers.

This hosta had the biggest flowers I’ve ever seen; at least three times the size of a “normal” flower.

I decided to visit Meetinghouse Pond in Marlborough one day to see what was growing there this year. Last year I found some really interesting plants there.

One of the first things I noticed at the pond was a big bull thistle (Cirsium vulgare,) all in bloom. I don’t usually see them bloom like this. They usually have two or three flowers and many closed buds waiting in the wings. You can see a bee loving the flower over in the upper left quadrant.

Asters grew in standing water at the shoreline. For that reason and the fact that the small, sword shaped leaves had no stems (petioles) I think they were bog asters (Oclemena nemoralis.) Each unbranched stem grew to about a foot tall and  had a single, light purple flower at its tip.

No matter what their name the flowers were beautiful. Because the plant usually grows in thickets in wet, swampy areas many people never see them.

This pond is the only place I know of to find native sneezeweed (Helenium autumnale.) I’ve never seen it anywhere else in the wild and I don’t know how it got here, but it was worth the drive to see it.

Sneezeweed’s common name comes from its dried leaves being used as snuff. It was inhaled to cause sneezing  because sneezing was thought to rid the body of evil spirits and both men and women used it. The Helenium part of the scientific name comes from Helen of Troy. One  legend regarding the plant says that it grew wherever her tears fell.

Sneezeweed has curious winged stems and this is a good way to identify them. It is a poisonous plant and no part of it should be eaten. It also contains compounds that have been shown effective in the treatment of tumors. The Native American Cherokee tribe used the plant medicinally to induce sneezing and as an aid in childbirth.

Japanese knotweed (Fallopia japonica) still blooms here and there but it’s pretty well finished for this year. Its final act will be to drop millions of seeds before it dies back completely until spring. This plant was brought to Europe from Japan sometime around 1829. It was taken to Holland and grown in nurseries that sold it as an ornamental. From there it found its way across the Atlantic where we still do battle with it today. It is one of the most invasive plants known and the only plant I have ever seen overtake it is purple loosestrife, which is also an invasive weed. Japanese knotweed is also a tough plant that is very hard to eradicate once it has become established.

Pink turtleheads (Chelone lyonii) still bloomed in a local park and though the flowers seemed fine the plants themselves looked terrible; all black and crisp leaves. My plants haven’t even showed color on the buds yet, but I hope they do better than these. I don’t know the origin of this plant and have never known if it was a native or a cultivar but it does very well in my yard and asks for nothing. Pink turtleheads are native to the southeastern U.S. and don’t seem to mind dryness in spite of naturally growing near water.

I always like to see if I can get a shot looking down the throat of the turtle. It’s very hairy in there but it doesn’t bother bumblebees. They were swarming over these plants on this day but I didn’t see any honeybees on these or any other flowers in the park.  

This little plant was hard to identify. I think I’ve tried for about three weeks off and on but I finally settled on catchfly (Silene armeria,) which is originally from Europe and which is also called sweet William catchfly. It is said to be an old fashioned garden plant in Europe. I’ve never seen it here but it is supposed to be a “casual weed” in New Hampshire. The name catchfly comes from the sticky sap it produces along its stem. Small insects are said to get caught in it but I didn’t see any on this single plant. Its leaves and stems were a smooth blue grayish color and along with the small pinkish purple flowers they made for a very pretty little plant that I’m hoping to see more of.

Just imagine becoming the way you used to be as a very young child, before you understood the meaning of any word, before opinions took over your mind. The real you is loving, joyful, and free. The real you is just like a flower, just like the wind, just like the ocean, just like the sun. ~Miguel Angel Ruiz
