Posts Tagged ‘Ornamental Datura’

We’ve still got some roadside color but many plants are now done blossoming for the year. Though there is purple loosestrife in this photo even that has mostly gone to seed, so we’ll see more asters and goldenrods than anything else from now on. Our largest and most showy aster, the New England aster, should be starting to bloom any day now.

Blue stemmed goldenrod (Solidago caesia) appears early on in summer but waits until September to bloom. Its stems grow vertically until the flowers begin to open and then they fall over into a more horizontal position, as if to show off the yellow blooms that grow in tufts all along the stem. This plant tolerates shade and seems to prefer places where it will only get two or three hours of sunlight. It isn’t considered rare but I know of only one or two places where it grows. It is also called wreath goldenrod.

The stems of blue stemmed goldenrod get their blue color from the same natural wax coating that is found on grapes, plums, blueberries and other plants. The coating is called a “bloom” and plants use it as a form of protection against moisture loss. It’s made up of tiny powdery, whitish crystals which reflect and scatter light in ways that can make the surface that they cover appear very blue. The wax crystals can be washed off by rain or melted by the sun, so many stems will be green before the plant blooms. You can see in the above photo how the blue color has gone in some places on the stem.

A flower head of woodland agrimony (Agrimonia striata) looks a lot like goldenrod from a distance and since it blooms at about the same time these are the only things that I can think of to explain why I’ve lived so long without ever seeing it until recently. The plant is also called roadside agrimony and that’s exactly where I found this example.

The small, bright yellow flowers of woodland agrimony grow in long spikes (racemes) on a small, knee high plant. It is said to be rare in parts of New England and I wonder if it is here, because this is only the third time I’ve ever seen it. It was growing in quite a shady area. 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.

Though its flowers resemble those of boneset, which flowers at the same time, white snake root’s (Ageratina altissima) large heart shaped, toothed leaves look nothing like boneset leaves. This plant is very toxic and in the early 19th century it killed thousands of settlers in the Midwest. A compound called trematol is passed from the plant to cows that graze on it and when humans drank the milk or ate the meat before too long they started to show signs of what was called “milk sickness.” In a week or less most would die of heart or liver failure. Abraham Lincoln’s mother died from what is believed to have been 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 and most likely saving thousands of lives.

Individual white snake root flowers are small, bright white, and fuzzy. The plant seems to prefer moist, shaded locations and doesn’t mind disturbed ground. It can often be found quite deep in forests and blooms from August into September. If you should happen to have farm animals or want to use boneset medicinally you should know it well.

White snake root should not be confused with white rattlesnake root (Prenanthes alba,) which is an entirely different plant in the aster family. This plant is not toxic, at least not enough to kill; the Native American Choctaw tribe used the tops of it in a tea that they used to relieve pain.

Beech drops (Epifagus americana) usually grow in deep shade and can be hard to photograph. This isn’t a good shot but it does show the plant’s growth habit and lack of leaves, which is what I’d like you to see. Beech drops grow near beech trees and are a parasite that fasten onto the roots of the tree using root like structures. They take all of their nutrients from the tree so they don’t need leaves, chlorophyll or sunlight. Beech drops are annuals that die off in cold weather, but they can often be found growing in the same place each year. Science doesn’t know much about which insects pollinate this plant but I often find spider webs on them so there must be insect activity on or near them. If you look closely at the plant in the above photo you can see a web on its top part.

Tiny pinkish purple flowers with a darker purplish or reddish stripe are the only things found on a beech drop’s leafless stems. On the lower part of the stem are flowers that never have to open because they self-fertilize. They are known as cleistogamous flowers. On the upper part of the stem are tubular chasmogamous flowers, which open and are pollinated by insects.

Jewelweed or spotted touch me not (Impatiens capensis) is still blooming but the lack of rain over the last couple of weeks has made them wilt badly. This plant typically blossoms right up until a frost but 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 jewelweed 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. In this photo the flower on the left is in the female stage and the one on the right is in the male stage. The flowers are dichogamous, meaning that the male and female parts mature at different times. That guarantees that the flowers can’t be self-pollinated. According to an article in the International Journal of Plant Sciences, when nectar is taken from a flower pollen collecting hairs are stimulated and the duration of the male phase of the flower is shortened. From then on it enters its female phase and waits for a visitor to dust it with pollen from another male flower. It’s no wonder these plants can produce so many seeds!

Friends of mine grow this beautiful daylily in their garden. It’s a very late bloomer for a daylily and would be a good one for a daylily grower wanting to extend the season. I think its name might be Athlone, an older variety introduced in 1942. Athlone is also a town in Ireland on the River Shannon.

Both dandelions and false dandelions (Hypochaeris radicata) have a rosette of edible leaves and a central taproot, but the flower stems of false dandelion are solid, tall and wiry while those of true dandelions are hollow and much shorter. False dandelion leaves are also much smaller and narrower than the dandelion’s leaves. The plant is a native of Europe.

The flowers of false dandelion look almost the same as those of true dandelions in a photo, but in the field they are much smaller and stand on 6-8 inch long, wiry stems. The plant is also called cat’s ear, possibly because of the bracts along its stem that look like tiny cat’s ears. I see them almost everywhere I go at this time of year.

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.

I always find silverrod in dry, gravelly places at the edge of the woods at 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. The flowers are quite small but pretty.

Queen Anne’s lace (Daucus carota) sometimes has a second blooming period into October. Though the flowers are smaller and not as tall they can almost fool you into thinking that it’s summer again.  When freshly cut Queen Anne’s lace flowers will change color depending on the color of the water in which they are placed, so if you put a bouquet into purple water you’ll have purple Queen Anne’s lace. There is already purple on this one though. If you look closely you can see a tiny purple flower in the center of this flower head.

Legend says the tiny purplish / reddish flower at the center of the flower head is a drop of blood shed when Queen Anne pricked herself while making the lace. A more believable story says that it helps attract pollinators, but the truth is scientists don’t really know why it’s there. It’s very difficult to get a good photo of because it’s so small.

They grow an ornamental datura (Datura metel) at the local college.  I’ve seen Datura many times, but never as beautiful as this. I think this one is a black Datura hybrid called Datura metel Fastuosa “Double Purple Blackberry.” A native Datura found here is called Jimson weed, which is a corruption of the original Jamestown weed, signaling where it was first found. Each blossom opens in the evening and lasts until about noon the following day.

I was there at evening when this blossom opened but these datura blossoms are doubled with many ruffles and they never really seem to be open. Bees in the know crawl in from the side and then down into the trumpet but I didn’t see any on this day. Datura contains several powerful toxic compounds and even the honey made from its flowers can sometimes lead to poisoning. The seeds and flowers are the most toxic parts of the plant, but they were used in sacred rituals for many thousands of years by Native American shamans and the plant is still called “Sacred Datura” by many. Native Americans knew the plant well though, and knew what dosages would and wouldn’t kill. Many with less experience have died trying to test the hallucinogenic effects of the plant.

Summer is leaving silently. Much like a traveler approaching the end of an amazing journey. ~Darnell Lamont Walker
