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.

Last Sunday I decided that a walk along the Ashuelot River in Keene was in order because this stretch of river is one of only two places I know of where gentians grow, and I wanted to see how they were coming along. They should bloom in a little over a month.

People have been walking along this path since long before I came along and it’s still a favorite of bike riders, dog walkers, joggers and nature lovers. On a good day you might see ducks, geese, blue heron, beavers, muskrats, squirrels, chipmunks and more birds than you can count here, as well as a wide variety of wildflowers and fungi. There have also been quite a few recent reports of a black bear in the area, but I was hoping that it was taking this day off.

You might even see something you’ve never seen before; that was my experience with this Asiatic dayflower (Commelina communis.) This is the first time it has appeared on this blog because this is the first time I’ve ever seen it. I was surprised by how small it was. 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; it seems to be quite rare here. I love that shade of blue.

Another introduced plant that can be called very invasive is purple loosestrife (Lythrum salicaria) and I was sorry but not surprised to see it here. If left unchecked it might very well be the only plant on these river banks a few years from now. It eventually chokes out almost every native plant it contacts.

Native Joe Pye weed (Eupatorium purpureum) grew along the river bank as well, and I hope it doesn’t lose the battle to purple loosestrife. I like seeing its dusty rose flower heads at this time of year.

Buttonbush (Cephalanthus occidentalis) also grew on the river bank but I couldn’t get near them because they were growing in the water. I was surprised because every other time I’ve seen this native shrub it was growing up high on the river bank well away from the water. The waterfowl will appreciate it being so close because they love the seeds.

This was one of a few strange things I saw on this day. I don’t know what it was all about but what struck me as even stranger than its being here in the first place was that hundreds of people have walked by it and nobody has touched it. I must have seen at least ten children walking or bike riding with their parents and I don’t know why they left it alone. They must be very well behaved. When my own son and daughter were little this would have been like a magnet to them.

This was another strange thing I saw. It was nailed to a pine tree and I don’t have any idea why.  I do know for sure that Europeans weren’t nailing metal tags to trees in New Hampshire in 1697 though.

Yet another strange thing I saw was a turtle that appeared to be trying to fly. It kept putting its hind legs up in the air and wiggling its toes in the breeze. I don’t know what it was trying to do but it seemed very happy to be doing it. Maybe it was just celebrating such a beautiful day.

A young robin flew into a nearby bush and watched the turtle trying to fly. It didn’t seem real impressed, but what bird would be?

Boneset (Eupatorium perfoliatum) and gray goldenrod (Solidago nemoralis) grew near the turtle’s log. At a glance common boneset looks like white Joe Pye weed. That’s because the two plants are closely related. In fact they can often be found growing side by side, but boneset blossoms a little later than Joe Pye weed here. I find it on river, pond and stream banks; almost always near water. The “perfoliatum” part of boneset’s scientific name means “through the leaf,” and that’s what boneset leaves look like; as if they had been perforated by the stem. The leaves joining around the stem as they do looked like bones knitting together as they healed to ancient herbalists, and that’s how the plant got its common name.

I’ve never seen pink lady’s slipper orchids (Cypripedium acaule) blooming along this stretch of the Ashuelot but the plants are here. I must not have walked this trail at the right time but I’ll be here next spring when they bloom.

There are many side trails off the main trail and every time I come out here I tell myself that I’m going to explore them one day but, even though I’ve been coming here since I was a boy, so far that day hasn’t come.

A crust fungus had nearly engulfed this entire tree stump. I think it was the netted crust fungus (Byssomerulius corium,) but I’ve never seen it get so big. It looked as if it was oozing right out of the stump.

White rattlesnake root (Prenanthes alba) is sometimes called white lettuce but it isn’t a lettuce, though they are in the same aster family that the lettuces are in. It’s probably thought to be another lettuce because it blooms at the same time and in the same locations as the wild lettuces do, but instead of the daisy like petals of lettuce flowers these look more bell shaped and lily like. The Native American Choctaw tribe used the tops of the plant in tea that they used to relieve pain. It is said that the common name comes from the way that some Native American tribes used the plant to treat snakebite.

Native long leaved pondweed (Potamogeton nodosus) also grew in the calm shallows. It likes to root in the mud and grow in full sun in warm standing water up to 4 feet deep. Many types of waterfowl including ducks and swans eat the seeds and leaves of this plant and muskrats like the stems. Many species of turtle eat the leaves, so it seems to be a plant that feeds just about every critter on the river. A man and woman came along when I was taking this photo and the woman came over to see what I thought was so interesting “Yuck, that’s disgusting!” she said. Since I see nothing disgusting about it her reaction to this important pond weed baffled me. Maybe she just doesn’t get out much.

Poison ivy (Toxicodendron radicans) is doing well this year; this plant was loaded with berries. They’ll ripen to a chalky white from the green seen here. I get into it every year and this year was no exception. One of my fingers has had a blister on it for about a week and is itching as I type this. Luckily it stays put on me and doesn’t spread, but I’ve known people who were hospitalized by it.

Tall blue lettuce (Lactuca biennis) isn’t being very blue this year. I keep hoping to find a plant with deep blue flowers but so far all I’ve seen are ice blue examples. There are hundreds of plants along this stretch of river and I know of many more that grow along a stream and some near a pond, so the plant must like to be near water, possibly due to the increased humidity.

Though I usually look for narrow leaf gentians (Gentiana linearis) near mid-August the bottle gentians (Gentiana andrewsii) along the Ashuelot were nowhere near blooming. Last year I found them blooming in mid-September, so I’ll wait awhile and come back. The plants looked good and healthy with plenty of buds and hadn’t been eaten by bug or beast, so they should bloom well.

I was born not far from this river and I first put my toes into it just about 50 years ago. I’ve been near it pretty much ever since but even after all this time I still see many things along its banks that I’ve never seen, and I guess that’s why I keep coming back. I hope there is a river in your life as well.

If you have a river, then you should share it with everyone. ~Chen Guangbiao
