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
