Posts Tagged ‘Bog Asters’

We’re almost at that point of peak flower production now as this view across a stream shows. Goldenrod, tall asters, Joe Pye weed, boneset, and purple loosestrife can all be seen here. We’re still waiting on New England asters but it shouldn’t be long.

The funny little plants called false dandelion (Hypochaeris radicata) have appeared in force and I’m seeing them everywhere. This plant gets its name from its resemblance to the dandelion, but it would be hard to mistake one for the other. The flowers are about half the size of a true dandelion and they bob around on long, wiry stems. At a glance you might think you were seeing a hawkweed flower when you look at a false dandelion flower because they’re close to the same size. One look at the leaves however, will show you that you’re seeing something entirely different because they resemble those of the dandelion more than hawkweed foliage. Hawkweed and false dandelion also bloom at different times, which helps when trying to identify them.

False dandelion leaves look like miniature versions of dandelion leaves and are nowhere near as wide or as long.

White wood asters (Aster divaricatus) lined a woodland path and made a pretty walk even prettier.

I always find silverrod in dry, gravelly places at the edge of the woods near 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.

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. The small flowers spiral up the stem and open from the top down.

Tansy (Tanacetum vulgare) is a European native that has been cultivated for centuries, even grown in the herb gardens of Charlemagne. It was brought from England by early colonists and by 1785 it had naturalized in New England. 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 has historically been used as such. Dried tansy added to the straw in mattresses was said to keep bedbugs away. I rarely see it in nature but it 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.

White rattlesnake root (Prenanthes alba) can be tough to identify because even plants growing side by side can have differently shaped leaves, but once they bloom identification becomes much easier. I can’t think of another plant that has small, drooping white, lily like blossoms at this time of year. The half inch flowers appear in clusters at the end of branched stems that can reach 5 or 6 feet in some cases, and have forked stamens that are longer than the petals. The plant gets its common name from the Native American belief that it could cure rattlesnake bites.

I saw a hosta recently in a park that was just another plain green unremarkable plant, but the reason I’m showing it here is because of its huge white flowers.

This hosta had the biggest flowers I’ve ever seen; at least three times the size of a “normal” flower.

I decided to visit Meetinghouse Pond in Marlborough one day to see what was growing there this year. Last year I found some really interesting plants there.

One of the first things I noticed at the pond was a big bull thistle (Cirsium vulgare,) all in bloom. I don’t usually see them bloom like this. They usually have two or three flowers and many closed buds waiting in the wings. You can see a bee loving the flower over in the upper left quadrant.

Asters grew in standing water at the shoreline. For that reason and the fact that the small, sword shaped leaves had no stems (petioles) I think they were bog asters (Oclemena nemoralis.) Each unbranched stem grew to about a foot tall and  had a single, light purple flower at its tip.

No matter what their name the flowers were beautiful. Because the plant usually grows in thickets in wet, swampy areas many people never see them.

This pond is the only place I know of to find native sneezeweed (Helenium autumnale.) I’ve never seen it anywhere else in the wild and I don’t know how it got here, but it was worth the drive to see it.

Sneezeweed’s common name comes from its dried leaves being used as snuff. It was inhaled to cause sneezing  because sneezing was thought to rid the body of evil spirits and both men and women used it. The Helenium part of the scientific name comes from Helen of Troy. One  legend regarding the plant says that it grew wherever her tears fell.

Sneezeweed has curious winged stems and this is a good way to identify them. It is a poisonous plant and no part of it should be eaten. It also contains compounds that have been shown effective in the treatment of tumors. The Native American Cherokee tribe used the plant medicinally to induce sneezing and as an aid in childbirth.

Japanese knotweed (Fallopia japonica) still blooms here and there but it’s pretty well finished for this year. Its final act will be to drop millions of seeds before it dies back completely until spring. This plant was brought to Europe from Japan sometime around 1829. It was taken to Holland and grown in nurseries that sold it as an ornamental. From there it found its way across the Atlantic where we still do battle with it today. It is one of the most invasive plants known and the only plant I have ever seen overtake it is purple loosestrife, which is also an invasive weed. Japanese knotweed is also a tough plant that is very hard to eradicate once it has become established.

Pink turtleheads (Chelone lyonii) still bloomed in a local park and though the flowers seemed fine the plants themselves looked terrible; all black and crisp leaves. My plants haven’t even showed color on the buds yet, but I hope they do better than these. I don’t know the origin of this plant and have never known if it was a native or a cultivar but it does very well in my yard and asks for nothing. Pink turtleheads are native to the southeastern U.S. and don’t seem to mind dryness in spite of naturally growing near water.

I always like to see if I can get a shot looking down the throat of the turtle. It’s very hairy in there but it doesn’t bother bumblebees. They were swarming over these plants on this day but I didn’t see any honeybees on these or any other flowers in the park.  

This little plant was hard to identify. I think I’ve tried for about three weeks off and on but I finally settled on catchfly (Silene armeria,) which is originally from Europe and which is also called sweet William catchfly. It is said to be an old fashioned garden plant in Europe. I’ve never seen it here but it is supposed to be a “casual weed” in New Hampshire. The name catchfly comes from the sticky sap it produces along its stem. Small insects are said to get caught in it but I didn’t see any on this single plant. Its leaves and stems were a smooth blue grayish color and along with the small pinkish purple flowers they made for a very pretty little plant that I’m hoping to see more of.

Just imagine becoming the way you used to be as a very young child, before you understood the meaning of any word, before opinions took over your mind. The real you is loving, joyful, and free. The real you is just like a flower, just like the wind, just like the ocean, just like the sun. ~Miguel Angel Ruiz
