Posts Tagged ‘Whorled White Wood Aster’

Joe Pye weed (Eutrochium fistulosum) has come into full bloom. Or full bud anyhow, most of the buds seen here haven’t opened yet. These plants towered over my head. Joe Pye is thought to have been a Native American healer who used this plant to treat early Massachusetts Bay Colony settlers suffering from typhoid fever, but the discussion over the origin of the name goes back and forth. For instance I’ve read that a Native word for the plant was “jopi,” which meant typhoid, and it is thought by some that jopi the plant name became Joe Pye the person’s name.

Monarch butterflies love Joe Pye weed flowers and I’ve already seen them on the open flowers this year.

Strangely, though boneset (Eupatorium) looks like a white joe Pye weed I’ve never seen a monarch butterfly on it. Joe Pye weed and boneset used to be in the same Eupatorium family but Joe Pye weed was has whorled leaves so it was moved to Eupatoriadelphus, from what I’ve read. Boneset has opposite leaves. 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.

Dewdrop (Dalibarda repens) is also called false violet because of its leaves, and I think that might be why it’s an easy flower to miss. Its small white flowers dot the forest floor like so many other small white flowers, and that also makes it easy to pass by with just a glance. A closer look reveals something different though; this plant produces other flowers that don’t open but still produce seeds. They are called cleistogamous flowers and are hidden beneath the leaves. The showy flowers like the one in the photo are mostly sterile. Dewdrop is one of the rarer flowers I see. It is endangered or threatened in many states and It likes swamps and moist woodlands.

Asiatic dayflower (Commelina communis) is rare here. I first found a single 6 inch high plant a couple of years ago and I was surprised by how small it was. The single plant had a single flower that I always thought  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 in this area because I’ve seen maybe two or three of them in 60+ years. I’d like to see more of them; I love that shade of blue.

There are enough different goldenrods (over a hundred it is said) which look enough alike to convince me that I don’t want to spend the rest of my life trying to identify them all, but some are quite easy to identify.  One of the easiest is gray goldenrod (Solidago nemoralis).  It’s one of the first to bloom and its flower heads always look like they have been in a gale force wind and were all blown over to one side of the stem.

After years of trial and error Thomas Edison found goldenrod to be the best domestic source of natural rubber and bred a plant that grew to twelve feet tall and contained about twelve percent rubber in its leaves. Henry Ford and George Washington Carver developed a process to make rubber from goldenrod on an industrial scale during World War II and the USDA took over the project until synthetic rubber was discovered a short time later.

Slender fragrant goldenrod (Solidago tenuifolia) is one of the easiest to identify because of its scent, which is said to resemble anise and sassafras. Since I’ve never smelled anise or sassafras I can’t confirm this, but its fragrance is pleasant so I always bend to give it a sniff when I see it. This plant closely resembles lance leaved goldenrod (Solidago graminifolia) but its leaves are narrower and have a single vein in each leaf. Lance leaved goldenrod leaves have 3-5 veins.

August is when our many asters begin to blossom here in New Hampshire and one of the first is the whorled wood aster (Oclemena acuminata). It’s one of the easiest asters to identify because of its early bloom time and because the narrow white ray florets look like they were glued on by chubby fingered toddlers. The plant can take quite a lot of shade and I usually find it growing alongside the edges of woodland paths. It gets its common name from the way its leaves appear to grow in whorls around the stem when viewed from above. In botany, a whorl is an arrangement of at least three sepals, petals, leaves, stipules or branches that radiate from a single point around the stem, and the leaves of this aster really don’t fit the definition. Looking at the from the side the tiers of whorled leaves of would appear flat like a plate, but these leaves appear randomly scattered up and down its length. The plant is also called sharp leaved aster and grows to about a foot tall.

Low baby’s breath (Gypsophila muralis) flowers are tiny; about the same size as those on red sandspurry, and blossom on the ends of wiry stems. Its leaves are also small and sword shaped and very hard to see in this photo. This entire plant covered maybe 3 inches.

 I find low baby’s breath growing in the sand on roadsides in full sun, much like a sandspurry would. It is an annual plant native to Europe and available commercially, sold as cushion baby’s breath.

Cup plants (Silphium perfoliatum) are native perennials with pretty flowers that can reach 8 feet. It’s called cup plant because its leaf pairs-one on each side of the square stem-are fused together and form a cup around the stem. This cup usually has water in it. 

Bees love cup plant blossoms.

I’m seeing more butterflies and moths this year than I ever have. Many small ones, about as big as my thumbnail, were loving this coneflower one day. Skippers maybe?

Steeplebush (Spiraea tomentosa) is easy to recognize because of the way its erect stems are unbranched, with steeple shaped flower clusters at their ends. They are usually found near water. This native plant is available commercially and is an excellent choice for butterfly gardens. Native Americans used a tea made from steeplebush leaves for easing childbirth.

I’ve watched invasive purple loosestrife (Lythrum salicaria) slowly take over the banks of this stream over the years. Slowly, it chokes out the natives asters, goldenrods, and Joe Pye weeds.

Showy tick trefoil (Desmodium canadense) is a legume in the bean family. This plant gets part of its common name from the little barbed hairs that cover the seed pods and make them stick to clothing like ticks. The “showy” part of its common name comes from the way that so many of its small pink flowers bloom at once. As the plant sets seeds its erect stems bend lower to the ground so the barbed seed pods can catch in the fur of passing animals. Deer, rabbits, woodchucks and even cows love to eat this plant. It has just come into bloom.

 I like showy tick trefoil because it blooms in late summer along with goldenrod and the colors go well together.

Native 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 I’ve discovered that 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.

But that isn’t all there is to the story of tearthumb. It comes by that name because it can 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. It actually uses these prickles for support when it climbs over other plants, and they work well. Tearthumb is considered a wetland indicator because it likes to grow in very moist to wet soil. I find it near ponds, blooming quite late in summer.

Jewelweed or spotted touch me not (Impatiens capensis) has started blooming but the lack of rain over the last couple of weeks has weakened their numbers. 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 like this example shows the flower is male. Female flowers will have a small green pistil in place of the pollen. 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 just so amazing.

A local business has a small flower garden packed with flowers of all kinds, and this beautiful sunflower was in it. It’s an amazing thing.

Burdock (Arctium lappa) is blooming and it hopes you’ll come by later and give it a ride. The plant a good example of a biennial plant. In the first year of life it grows leaves and in the second year it flowers, sets seeds, and dies. This is what biennials do, so we know that its tubular flowers with purple stamens and white styles signal that it is close to finishing its journey. There is no reason to grieve though, because the germination rate of its seeds is high and there will surely be burdocks for many years to come, especially if you (or your dog) help spread them around.

Burdock is said to have been introduced from Europe because it was noted in 1672 by self-styled naturalist John Josselyn, who wrote that it had “sprung up since the English Planted and kept Cattle in New-England.” He said the same thing about the dandelion, but fossil evidence proved him wrong. Native American tribes across the country had many uses for burdock, both as a medicine and food, so some form of the plant had to have been here long before European settlers arrived. Its spread across the country from New England to the Pacific took about 270 years, because the Native Americans of western Washington State said it had been recently introduced there in the 1930s.  Burdock’s tubular purple flowers are densely packed into round prickly flower heads, but though many are familiar with the flower heads few seem to ever notice the flowers. As the above photo shows, when fully open long white styles grow from the dark purple flowers.

No matter how many times I see the Allegheny monkey flower (Mimulus ringens) I don’t see a monkey, but whoever named it obviously did. This plant gets about knee high and likes to grow in wet, sunny places, and it isn’t all that common. I usually have a hard time finding it. This year though, for the first time, I found several plants growing beside the river in Keene.

Allegheny monkey flowers have square stems and are also called square stemmed monkey flowers. The throat is partially closed and bumblebees are one of the few insects strong enough to pry it open to get at the nectar. Native Americans and early settlers sometimes used the leaves as an edible green.

I’ve searched for years for floating heart plants (Nyphoides cordata) growing close enough to shore to get photos of and this year I finally found them. In fact I found hundreds of examples of this tiny native waterlily very close to shore. They have small, heart-shaped, greenish or reddish to purple leaves that are about an inch and a half wide, and that’s where their common name comes from.  

The tiny but very pretty flowers of floating heart are about the size of a common aspirin, but are still every bit as beautiful as the much larger fragrant white water lily blooms they resemble. They grow in bogs, ponds, slow streams, and rivers. I was very happy to finally see them up close.

Showy tick trefoil (Desmodium canadense) is a legume in the bean family. This plant gets part of its common name from the little barbed hairs that cover the seed pods and make them stick to clothing like ticks, much like enchanter’s nightshade. The “showy” part of its common name comes from the way that so many of its small pink flowers bloom at once. As the plant sets seeds its erect stems bend lower to the ground so the barbed seed pods can catch in the fur of passing animals. I saw these examples in an unmown meadow.

Showy tick trefoil has pretty flowers that are obviously in the pea / bean family. It is also called Canada trefoil. One odd fact about this plant is that there are no known uses of it by Native Americans or colonials. From my experience that’s rare among native plants in this area. Maybe they just picked the beautiful flowers and used them to decorate their homes.

I saw these striking daylilies in a local children’s park. The plant breeders are obviously still trying to breed a black daylily but they haven’t quite got it yet.

They grow an ornamental datura (Datura metel) at the local college.  I’ve seen Datura many times, but never as beautiful as these. 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’ve gone to see them several times this year but I can’t find a blossom fully opened, so this will have to do. these datura blossoms are doubled with many ruffles and they never really seem to be fully 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 datura 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. This is the strange, spiky seed pod of this datura.

Zinnias grow in the same garden as the datura and this one caught my attention. These flowers are usually swarming with painted lady butterflies but I haven’t seen a one yet this year.

But I have seen plenty of garden phlox! It’s another of those flowers that whisper of autumn’s approach. I pretend I’m deaf for as long as I can though, and just admire their beauty.

Slender fragrant goldenrod (Solidago tenuifolia) is a goldenrod that’s easy to identify because of its long slender, willow like leaves and its pleasant, vanilla like fragrance that is impossible to describe. 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. It is also called flat topped goldenrod. Insects of all kinds swarm over slender fragrant goldenrod and you have to be careful that you aren’t going to inhale one when you smell it.

Whorled white wood aster (Oclemena acuminata) gets its common name from the way its leaves appear to grow in whorls around the stem from above. In botany, a whorl is an arrangement of at least three sepals, petals, leaves, stipules or branches that radiate from a single point around the stem, and the leaves of this aster really don’t fit the definition. Looking at them from the side the tiers of whorled leaves would appear flat like a plate, but these leaves appear randomly scattered up and down the stem’s length. The plant is also called sharp leaved aster and grows to about a foot and a half tall. It’s one of the easiest asters to identify because of its early bloom time. The plant can take quite a lot of shade and I usually find it growing alongside the edges of woodland paths.

Tall blue lettuce (Lactuca biennis) can get very tall indeed and often towers over my head. A cluster of small, pencil eraser size, blue flowers sits at the tip of the long stem. This plant is very similar to the wild lettuce (Lactuca canadensis) which bears yellow flowers. Both plants were used medicinally by Native Americans but they should only be used by those who know them well, because it is said that they can cause death by cardiac paralysis. The flowers of tall blue lettuce can be white, deep blue, or ice blue. The deep blue ones are always the hardest to find but also the most beautiful and worth the effort. I haven’t seen a single one this year though.

Mad dog skullcap (Scutellaria laterifolia) almost always blooms in pairs on grassy hummocks near rivers and ponds and that’s where I always find them. The skullcap part of the common name comes from the calyx at the base of the flower, which is said to look like a medieval skull cap. The plant was once thought to cure rabies, and that is where the “mad dog” part of the common name comes from.

There is powerful medicine in both mad dog and marsh skullcap and when Native Americans wanted to go on a spirit walk or vision quest this was one of the plants they chose. The small blue and white flowers always grow in pairs in the leaf axils. Those of mad dog skullcap are slightly smaller.

You don’t need to be on a vision quest to see the beautiful light that shines from this purple morning glory (Ipomoea purpurea) that grows on the fence at the local post office. Unlike the wild bindweeds morning glory is an annual, so it grows new from seed each year. Postal workers must love it because I’ve seen the bed it grows in weeded down to bare ground, but the morning glories are always left to grow. I’m not surprised; how could anyone pull up something so beautiful?

Little things seem nothing, but they give peace, like those meadow flowers which individually seem odorless but all together perfume the air. ~George Bernanos
