More Mid-July Flowers

Asters in mid-July? I couldn’t believe my eyes when saw this aster blooming along a roadside. Asters will sometimes bloom in mid-August but most usually wait until the end of August and even into September. They can be hard to identify and this one had me scratching my head until I looked at the leaves. There is only one aster that I know of with big, hand size leaves and that is the big-leaved aster (Eurybia macrophylla.) But that aster has always had white flowers in my experience, so I had to hit the books to find out what was going on. According to what I read the big-leaved aster can indeed have purple flowers, but this is the first one I’ve seen wearing that color. You really do learn something new every day in nature.

This is an example of the big leaf found on the big-leaved aster. They grow at the base of the stem at ground level, and get smaller higher up on the stem. Big leaf asters are one of the first to bloom in this area.

Our native purple coneflowers (Echinacea purpurea) have just started blooming. This plant is well known for its medicinal qualities as well as its beauty. According to the USDA the plant was used by many Native American tribes throughout North America to treat a variety of ailments. It was used as a pain reliever, anti-inflammatory, as a treatment for toothaches, coughs, colds, and sore throats. It was also used as an antidote for various forms of poisonings, including snake bite. Portions of it were also used to dress wounds and treat infections. Modern medicine has found it useful to combat bacterial and viral infections and as an immune system booster. I grow it because butterflies and bees like its nectar, birds like the seeds, and I like to admire its beauty.

This is only the second time Asiatic dayflower (Commelina communis) has appeared on this blog because it is rare here. I first found the 6 inch high plant last year and I was surprised by how small it was. The single plant had a single flower that I thought it would be as big as a tradescantia blossom but it was only half that size. It is an introduced plant from China and Japan but it could hardly be called invasive because I’ve seen exactly two of them in 60+ years. I’d like to see more of them; I love that shade of blue.

Brittle stem hemp nettle (Galeopsis tetrahit) is originally from Europe and Asia and is considered highly invasive in some areas, but it is hard to find here. It is an annual, growing new from seed each year. Its small purple flowers grow in whorls near the top of the plant, which is often branched.

Brittle stem hemp nettle flowers have a large 3 part lower lip where insects land. From there insects can follow dark purple stripes into the blossom. Once inside they’ll pick up some pollen from the 4 stamens that arc along the inside of the upper lip and hopefully pass it on to another flower. This example had lots of pollen to share. The 3/4 inch long flowers have long white hairs on their upper lip and the square stems are also covered in hairs. When you run your fingers over any part of the plant you can feel its stiff, bristly hairs but they don’t embed themselves in you, thankfully

When I was a boy all I ever saw were pure white bindweed flowers but then all of the sudden they became pink and white bicolor bindweed flowers. Now it has gotten difficult to find a white example but I saw this one and many more with it in a field recently. It reminded me of playing in milkweed scented fields with grass up to my shoulders watching big black and yellow garden spiders weaving their nests. I never see them anymore either.

Soapwort’s (Saponaria officinalis) leaves contain a natural soap called sapronin. When the leaves are crushed and scrubbed together in water a soapy lather forms. In the past this plant was used for washing clothes and making soap. It hails from Europe and though it is used medicinally it is considered toxic and some people have violent toxic reactions to it. I’ve heard that soapwort is also called bouncing bet because of the way the unusual recurved petals bounce the flowers in a breeze, but I’ve also heard that bouncing bet was a name once used for a laundry woman. It grows to about knee high on a good day but I’ve also seen it sprawl along the ground. It was originally introduced as a garden plant and promptly escaped.

Soapwort flowers can be pink or lavender in full sun and whiter in shade. They usually have 10 stamens and always seem to have quite narrow petals when compared to the more rounded petals of a plant like phlox. The more curved the petals it is said, the older the flower.

Tansy (Tanacetum vulgare) is a European native that has been cultivated for centuries. 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 was used as such in colonial times. Dried tansy added to the straw in mattresses was said to keep bedbugs away. Most tansy plants are seen in gardens but it had naturalized itself in New England by 1785 and 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.

I saw a beautiful flower on the side of the road and stopped to see something I had never seen. I loved the color of it.

A closer look told me it was a campanula and after some research I think it might be a clustered bellflower (Campanula glomerata,) which is a garden escapee. It is said to be a “vigorous rhizomatous perennial” originally from Europe and Japan. This is the first time I’ve seen it but I wonder how long it will take before it is a common sight along our roadsides, like the highly invasive purple loosestrife. There were several plants in this spot.

There are a few orchids blooming now and one is the broad leaved helleborine orchid (Epipactis helleborine.) These orchids are originally from Europe and Asia and were first spotted in this country in Syracuse, New York in 1879. The plant has now spread to all but 19 of the lower 48 states and is considered an invasive weed. It doesn’t act very invasive here; I usually see only a few plants each year and every time I see them they’re growing in deep shade. I’ve never been able to find out how the plant comes by its common name. It seems a bit odd because it doesn’t seem to resemble either hellebore or false hellebore, though the pleated leaves are close to those of false hellebore.

As I was taking photos of the tiny flowers an even tinier insect showed up. Scientists have discovered that the flowers of the broad leaved helleborine orchids have a secret; their nectar contains the strongest narcotic compounds found in nature; comparable to oxycodone they say, and when insects sip it they get quite a buzz and tend to stagger around for a while. This increases their chances of picking up the orchid’s pollinia, which are sticky little sacks of pollen that orchids produce instead of the dust-like pollen produced by many other flowers. I’m sorry this photo is so poor but these orchids grow in the shade and this is an extreme close up.

Once the insect flies off it will most likely be stoned enough to be oblivious to the pollen packets that it has stuck all over itself. By transporting its pollinia to another helleborine flower the insect will have repaid the orchid for its intoxicating nectar. But it doesn’t happen quickly; this insect crawled right into the cup and decided to stay for a while. Maybe it was too tipsy to fly.

Arrowleaf tearthumb (Polygonum sagittatum) is in the smartweed family, which gets its common name from the way your tongue will smart if you eat its peppery parts. Though the flower buds in this family of plants seem like they never open they do, sort of. They look like they only open about halfway though and I find the buds as pretty as the blossoms. This plant is a kind of rambler / sprawler that winds its way over nearby plants so it can get as much sunshine as possible. It often grows in deep shade but it will also grow in full sun, so it has covered all the bases.

Tearthumb got that name because it will indeed tear your thumb or any other body part that comes into contact with it. Many a gardener has regretted trying to pull it up without gloves on, because when the small but sharp barbs (prickles, botanically) along its stems slip through your hand they act like a saw and make you sorry that you ever touched it. The plant uses these prickles for support when it climbs over other plants, and they work well. Sometimes the stems and prickles are red but in this example they were green. Tearthumb is considered a wetland indicator because it likes to grow in very moist to wet soil. I almost always find it near water, often blooming quite late into summer.

I remembered a spot where last year I saw what I thought were the only examples of panicled tick trefoil (Desmodium paniculatum) I had ever seen. When I returned this year I was very happy to see that there were even more plants but I have done more research and discovered that I misidentified them. Though the long thin shape of its flower head is correct the flowers are not.

After quite a lot of searching I’m not finding this one in my guide books or online under trefoil or Desmodium so now I’m wondering if it even is a trefoil. It’s definitely in the pea / bean family but that’s as far as I can go. It’s quite pretty and grows along a roadside in full sun. Each plant is probably about 3 feet tall but they lean on surrounding plants and each other so they’re all in a jumble. If you happen to know its name I’d love for you to let me know.

The pale yellow flowers of tall lettuce (Lactuca canadensis) are often tinted by red or pink on their edges. This is a native lettuce that can reach 10 feet tall with clusters of small, 1/4 inch flowers at the top of the stalks. The leaves of this plant can be highly variable in their shape, with even leaves on the same plant looking different from each other.  Native Americans used this plant medicinally. The milky white sap contains lactucarium, a sedative and analgesic. It is still used in medicines today.

Away from the tumult of motor and mill
I want to be care-free; I want to be still!
I’m weary of doing things; weary of words
I want to be one with the blossoms and birds.

Mid August Flowers

Right now wildflowers, both native and non native, seem to bloom on every square foot of available space in some places. The view across this stream showed the yellows of several varieties of goldenrod and St’ John’s wort, purple loosestrife, the whites of asters and boneset, and the dusty rose of Joe Pye weed. Scenes like this are common at this time of year but that doesn’t diminish their beauty.

Native grass leaved arrowhead (Sagittaria graminea) grows in the calm water of streams and ponds. There are about 30 species of arrowheads out there and many of them are similar, so I hope you’ll take my identification with a grain of salt. Common to all arrowheads is how they grow in shallow, still waters at pond and stream edges, or in the wet ground of ditches and swamps. Grass leaved arrowhead has flower stalks shorter than the leaves. I took this photo early one morning and this example was very wet with dew.

If you know arrowheads at all then this photo probably surprises you, because this leaf looks nothing like the usually seen common arrowhead leaf. The plant is also called slender arrowhead, and I’m assuming it’s due to the leaf shape.

Common arrowhead (Sagittaria latifolia) is also called broadleaf arrowhead and duck potato, because ducks eat its small, potato like roots and seeds. All arrowheads that I’ve seen always have three pure white petals, but I’ve heard that some can be tinged with pink. Flowers are about an inch across. In late fall or early spring, disturbing the mud in which they grow will cause arrowhead’s small tuberous roots to float to the surface. They are said to have the texture of potatoes but taste more like chestnuts. They were an important food for Native Americans, who sliced the roots thinly and dried them and then ground them into a powder that was used much like flour. Ducks, beavers, muskrats and other birds and animals eat the seeds, roots, and leaves.

Virgin’s bower (Clematis virginiana) is a late summer blooming native clematis vine that drapes itself over shrubs so it can get all of the sunshine that it wants. I’ve also seen it climbing into trees, but in this photo it has set its sights considerably lower and grew over a stand of yarrow. As long as it finds the sunshine it needs, it doesn’t matter what it grows on.  An extract made from the plant is hallucinogenic (and dangerous) and was used by Native Americans to induce dreams. Mixed with other plants like milkweed, it was also used medicinally. It is a very toxic plant that can cause painful sores in the mouth if eaten.

Another name for this vine is traveler’s joy, which it is, but its small white flowers are another reminder that fall is near.

Slender gerardia (Agalinis tenuifoliais) is a shy little plant that grows in the tall grass at the edge of meadows and I usually find it growing in full sun. It has the unusual habit of dropping all of its opened flowers each afternoon. It opens fresh buds at the start of each day, which means that its flowers don’t even last for a full day, so insects (and photographers) have to be quick. The plants that I find are always 6-8 inches tall but I’ve read that they can reach 2 feet.

Slender Gerardia is also called false foxglove. There might be a faint resemblance but I think it would be hard to confuse the two, especially after a good look at the slender, sword shaped leaves. The blossoms are very hairy and have a long curved protruding pistil and especially from the side look nothing like foxglove to me.

Another reason I doubt that slender gerardia could ever be confused with foxglove is its size. You could fit a few gerardia blossoms in a single foxglove blossom.

I’m seeing a lot of flowers this summer that I’ve never seen before and I thought this was one of them, but my blog tells me that I have seen it once before. There are about 15 different species of agrimony but I think this one is woodland agrimony (Agrimonia striata.) The small, bright yellow flowers grow in long spikes (racemes) on a small, knee high plant. Research shows that the plant is threatened in New York and Maryland and I wonder if it is rare here. I’m surprised that I’ve only seen it twice.  It is also called roadside agrimony, though I’ve never seen it there. Agrimony has been used medicinally for many thousands of years, dating back to at least ancient Egypt but though woodland agrimony is native to the U.S. and Canada I can find no information on how it was used by Native Americans.

I usually stay away from goldenrod identification because there are so many of them that even botanists get confused, but slender fragrant goldenrod (Solidago tenuifolia) is easy because of its long, slender leaves and its fragrance. The only other similar goldenrod is the lance leaved goldenrod (Solidago graminifolia) but its leaves are wider and have 3 to 5 veins as opposed to the single vein in a slender fragrant goldenrod leaf.  Still, I always smell them just to be sure.

I wrote about boneset (Eupatorium perfoliatum) in the last post but since it’s so common at this time of year I thought I’d show it again. At a glance it looks like white Joe Pye weed, but a close look at the foliage shows that it’s a very different plant. This example had a visitor, up there on the right.

The perfoliatum part of boneset’s scientific name means “through the foliage” and that’s how its stem appears to grow; as if the leaves have been perorated by it. The common name comes from the way that the joined leaves looked like broken bones knitting themselves back together. Joe Pye weed leaves have leaf stems (petioles) and look very different. Boneset was a very valuable medicine to Native Americans and they showed early settlers how to use the plant to reduce fever and relieve coughs and congestion. It was also used to ease aches and pains of all kinds.

Here was a nice stand of Joe Pye weed (Eupatorium purpureum) growing at the edge of the forest. Even from a distance it is easy to see how different the foliage is from boneset. If you’re trying to identify the two plants when they aren’t blooming it helps to know how their foliage is arranged.

Yellow toadflax (Linaria vulgaris) is considered an invasive species in some areas but I don’t see it that often and when I do it’s in fairly small colonies of up to maybe a hundred plants. These few examples grew next to a cornfield. The plant is from Europe and Asia and has been in this country since it was introduced from Wales as a garden flower by Ranstead, a Welsh Quaker who came to Delaware with William Penn in the late 1600s. It has been used medicinally for centuries, since at least the 1400s, and modern science has shown it to have diuretic and fever-reducing qualities.

Because the flower is nearly closed by its lower lip it takes a strong insect like a bumblebee to pry open and pollinate yellow toadflax. When it is grown under cultivation its flowers are often used as cut flowers and are said to be long lasting in a vase. It always reminds me of snapdragons and goes by many common names. “Butter and eggs” is probably one of the best known and “Dead men’s bones” is probably one of the least known.

Big leaf asters (Eurybia macrophylla) need big, light gathering leaves because they grow in the forest under trees. The leaves on this plant are very different from other asters, so it’s a hard plant to misidentify. As is common on many asters the flowers look like they were glued together by a chubby fisted toddler.

The leaves on big leaf aster are heart shaped and about as big as your hand. They are especially impressive when they grow in large colonies. I’ve seen whole hillsides with nothing but these big leaves growing on them, so they must shade out other plants or have something toxic in their makeup that doesn’t allow other plants to grow.

After seeing broad leaved helleborine orchids blooming I knew that it was nearly time for downy rattlesnake plantain orchids (Goodyera pubescens) to bloom, so I visited a small colony I know of. This native orchid has tiny white flowers but I like its mottled silvery foliage as much as its blossoms.  The flowers grow on a relatively long stalk and though I’ve tried hundreds of times I’ve been able to show the flower stalk and basal leaves together clearly in a photo only once. This orchid grows in the woods usually in deep shade, but I find that most plants get at least an hour or two of sunshine no matter where they grow, and I just happened to be there when this one had its moment in the sun.

I’ve learned from many frustrating attempts at photographing this plant to carry a small 8 X 10 inch piece of black foam core board with me because its narrow racemes and tiny flowers are easily lost in the background vegetation.

I’ve taken hundreds of photos of downy rattlesnake plantain orchid flowers but this is the only time I’ve seen any color except white in one. I suppose the yellow color must be nectar, but I don’t know for sure. The tiny flowers look like miniature versions of our native pink lady’s slipper orchid flowers. Each one is so small it could easily hide behind a pea with room to spare. This photo also shows where the “downy” part of the common name comes from. Everything about the flower stalk is hairy.

I was driving along the highway north of Keene when I saw a flash of beautiful blue, so of course I had to go back and see what it was. I was happy to see a large stand of chicory (Cichorium intybus) still blooming while all the other chicory plants I know of finished blooming weeks ago. I love the beautiful blue color of these flowers and if I could have a yard full of them I would.

Narrow leaved gentian (Gentiana linearis) blossoms are also a beautiful shade of blue. These flowers appear identical to those of bottle gentians (Gentiana andrewsii) but the foliage is quite different. Narrow leaf gentians like moist, calcium rich soil and that’s one reason you don’t see them in this area very often. Another reason is that the flowers never open so insects have to force their way in, and it takes a strong insect like a bumblebee to do so. Third is how its seeds are too small to interest birds and its foliage too bitter to interest herbivores. Put all of that together and it’s a wonder that this plant is seen at all. It’s listed as rare, endangered or vulnerable in many areas. These examples grow in a roadside ditch in Nelson, which is north of Keene.

That pleasure which is at once the most pure, the most elevating and the most intense, is derived, I maintain, from the contemplation of the beautiful. ~Edgar Allan Poe

Mid September Wildflowers

We had a light frost here yesterday morning, so there probably won’t be too many more wildflower posts for this year. I’m going to miss them!

I found a few of these native field milkwort (Polygala sanguinea) flowers in an old pasture, growing in very sandy soil. One way to identify this plant is by its taproot, which smells like wintergreen. Another way is by its leaves, which should be alternate as the photo shows, and not whorled. The sepals on this flower shade from purple at the top to white at the base in this case, but its flowers can also be white or green. The “poly” part of the scientific name means much in Greek and “gala” means milk. It was once thought that cows eating this plant would produce more milk, and that’s how the plant got its common name.

Beech drops (Epifagus virginiana) are parasitic plants that insert a root-like structure called a haustorium into a beech tree’s root, taking what they need from the tree to stay alive. Since they are parasitic they don’t need chlorophyll and aren’t green. Instead the leafless stems are pale, yellowish green and the flowers can be wine red to pink to yellowish in color, sometimes with brownish purple stripes. This plant is also called cancer root because of the false belief that it cured cancer. It is related to Indian pipes and pinesap plants. Native Americans made a bitter tea from it.

A closer look at the small flowers of beech drops. The plant is self-fertilizing but is also visited by insects.

Dodder (Cuscuta) is another parasitic plant, but it isn’t limited to one kind of host like the beech drops. It can live off many different kinds of plants. Dodder is an annual and grows from seed in the spring. It wraps itself around the stem of another plant and pushes growths called haustoria into the stem of the host plant. If you look just to the upper left of the white flower in the photo you can see how the orange dodder stem has burrowed into the goldenrod stem. Once it is feeding on its host it loses all connection to the soil. This plant has no chlorophyll and its stems are bright orange. The round growths are seed pods.

 

I was surprised to see this purple flowering raspberry (Rubus odoratus) in September-it usually starts blooming in June and might bloom into July in a good year. This shrub is in the rose family and might be mistaken for a rose if it wasn’t for its large, maple-like leaves. Its stems are hairy but not prickly like a rose. The native shrub will reach 3-6 feet tall and twice as wide under the right conditions.

Silverrod (Solidago bicolor) is in the goldenrod family and is also called white goldenrod. It is the only white flowered goldenrod found in the northeast and is a native. Seeing these flowers always reminds me that the growing season is nearly over. I usually find it in dry, gravelly places at the edge of the woods. As the flowers age they fade and change color slightly, and that’s where the bicolor part of the scientific name comes from.

 

Obedient plant (Physostegia virginiana) is native to central and southern U.S. but in my experience, will grow just about anywhere.  I planted some in my yard several years ago to try to attract hummingbirds and it has been trying to take over ever since. Each year I weed it out, thinking that I’ve finally gotten rid of it only to find it growing in a different spot the following year. Its small snapdragon like flowers can be white or pink and are quite beautiful.

The small, hairy flowers of slender gerardia (Agalinis tenuifolia ) are small and grow close to the ground, so they are easily missed. This plant is also called slender foxglove because its tube shaped flowers are similar in appearance to those of foxglove. The narrow leaves and wiry stems remind me of toadflax. An odd fact about this plant is that it turns black when it is dried, so it is not a good plant to press for herbarium specimens. It grows in fields and gravelly waste areas-often next to forked blue curls (Trichostema dichotomum).

Slender gerardia flowers last only for a single day, opening in the morning and closing at night. By midafternoon they begin to take on a wilted look, so photographing them is best done at mid-day. Bees pollinate these flowers, and I see plenty of them when I visit these plants.

I find sand jointweed (Polygonella articulata) growing in sand, just as its common name suggests. These plants grow to about a foot tall with thin, wiry stems and small white or pink flowers. The leaves are very small and lie against the stem so the plant appears leafless. The plant gets its name from the curious way the stems are jointed. I’m not sure why, but this is one of the hardest plants to photograph that I’ve ever met.

 

Big leaved asters (Eurybia macrophylla) grow quite deep in the woods, so they have large leaves with enough surface area to collect what dim light is available. There is no hard and fast rule, but plants with larger leaves can often take more shade. It seems odd to see aster flowers topping a plant with such large, 8 inch long by 6 inch wide leaves. These plants grow in large colonies and I’ve seen entire hillsides covered with them. The flowers can be white, pale violet, or purple. Some Native American tribes used the plant’s roots in soup and its young spring leaves as food or medicine.

White snakeroot (Eupatorium rugosum ) is very toxic and in the early 19th century killed thousands of people-especially settlers in places like Indiana and Kentucky. In just one Indiana County half the deaths were said to be caused by this plant. A compound called trematol is passed from the plant to cows that graze on it, and their milk becomes toxic. When humans drank the milk before too long they started to show signs of what was called “milk sickness” and in a week or less would be dead from heart or liver failure. Abraham Lincoln’s mother died from milk sickness when he was just 9 years old. All parts of the plant are toxic to cattle, horses, sheep, and humans. Today’s farmers eradicate the plant from their pastures and mix the milk from many cows together, so milk sickness is almost unheard of. A Native American woman from the Shawnee tribe is credited with finally warning settlers about this plant.
