We still have plenty of flowers blooming as this view of a local pond side shows, but from this point on we’ll have very few new ones coming along. There will be a few more asters and a goldenrod or gentian or two but for the most part what you see here is the season finale for wildflowers.
Garden flowers on the other hand, will steal the show until the foliage begins to show color. Many will bloom right up until a hard frost but chances are this sunflower that I saw in the garden of some friends won’t make it quite that long. Sunflowers are a very pretty flower and I wish I’d see more of them but not many people seem to grow them.
If I said “St. John’s wort” chances are good that most people would think of a yellow flower with a lot of stamens, but marsh St. John’s wort (Hypericum virginicum) is very pink. As its name implies this plant likes saturated soil and will even grow in standing water at the shoreline of ponds. The flowers are quite small; about 3/4 of an inch across on a good day, but usually more like 1/2 an inch. This little shin high plant grows south to Florida and crosses the Mississippi River only in Texas and Oklahoma.
The bright red flower buds of marsh St. John’s wort are as pretty as the flowers.
This crooked stem aster (Symphyotrichum prenanthoides) is the first blue aster I’ve seen this year. I found this plant growing in a very wet, sunny meadow. I don’t usually try to identify asters but the one inch diameter light blue flowers and zigzagging stems make this one easier than most.
In my last flower post I showed the purple stemmed aster (Symphyotrichum puniceum) which, if I was going by color and flower size alone would look identical to me, but my color finding software says that the flower on that one is purple and this one is blue. That and the zig zag stems lead me to the crooked stemmed aster. The Native American Iroquois tribe used this plant medicinally to treat fevers and other ailments.
It’s already time to say goodbye to my beautiful little friends the eastern forked blue curls, which surprised me by following me home and growing in my own yard. I spend a lot of my free time searching for flowers and trying to remember where each one of them grows, so any that choose to grow here are very welcome indeed, especially when they’re as beautiful as this one.
It’s also time to say goodbye to brown knapweed (Centaurea jacea.) Since the plant is so invasive in certain places I suppose I should be glad that it hasn’t followed me home, but I do like its flowers. They’re colorful and unusual and I enjoy seeing large colonies of them all blooming at once. They really don’t seem very invasive here.
Nodding smartweed (Polygonum lapathifolium) gets its common name from its drooping flower heads and the very sharp, peppery taste of the stems, which makes the tongue smart. It doesn’t seem to bother ducks, geese, and all of the other animals that eat it, though. The plant is also called curly top smartweed; obviously because of the way the long flower spikes droop. It is originally from Europe.
Each nodding smartweed flower spike is made up of many pink to white, very small flowers. The flowers never seem to fully open, which can make it hard to count any of their reproductive parts, but each one has 5 sepals and no petals. There are also six stamens, two partially fused carpels and two styles.
Another name for nodding smartweed and some other Polygonum species is lady’s thumb, and they get that name from the dark spot that appears on each leaf. Legend has it that a lady with a dirty thumb (apparently) left the smudge like mark on a leaf and it has been there ever since. There are over 200 species of Polygonum.
Pilewort (Erechtites hieracifolia) is a strange plant with inch long flower buds that never seem to open beyond what you see in the above photo. This plant gets its common name from the belief that it was useful in the treatment of piles (hemorrhoids,) because the buds are the size and shape of suppositories. The Native American Algonquin people used the plant to treat poison ivy (Toxicodendron radicans) and poison sumac (Toxicodendron vernix) rashes. It has also been used as a source of a blue dye for cotton and wool.
Even after they open pilewort flowers still look like they are in the bud stage, so you have to look at them closely. This photo shows about all we can see of them. The flower is made up of many tiny florets which are pollinated primarily by wasps and hornets. In some areas it is called burn weed because of the way it moves quickly into burned areas. I usually find it along river and stream banks.
Once they go to seed potential pileworts will float away on the wind much like dandelion seeds.
I find spearmint (Mentha spicata) growing in the sunshine at the edge of the woods. Like wild mint (Mentha arvensis) spearmint has been used since before recorded time both medicinally and as a flavoring. Pliny wrote of it and the ancient Romans cultivated it to scent their bath water. Spearmint is originally from Europe but the Pilgrims brought it on their first trip to America, so valuable was the plant to them.
Instead of growing in the leaf axils as they do on wild mint, spearmint flowers appear at the top of the stem. They are said to be pink or white but these were white, blue, pink and lavender. Their scent is very refreshing on a hot summer day and always reminds me of spearmint gum. Imagine; you are seeing flowers that people admired 2000 years ago.
Native common yellow wood sorrel (Oxalis stricta) is unusual because it grows in woods or meadows and I see it in both. It’s considered a weed by many and is largely ignored by most, but it’s a very interesting plant. Its raw leaves can be chewed as a thirst quencher if you forgot to bring water on your hike. The Native American Kiowa tribe called it “salt weed” and used it that way for long walks. Its seed capsules can also be chewed but they can also explode when mature and can fling seeds up to 13 feet away. They are said to be tart with a flavor similar to rhubarb. The plant is high in vitamin C and it can be pressed to make a passable vinegar substitute.
August is when many of our asters begin to blossom here in New Hampshire and one of the first is the whorled wood aster (Oclemena acuminata.) It 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 leaf arrangement of this aster really doesn’t fit the definition.
Looking at them from the side the tiers of whorled leaves would appear flat like the edge of a dinner plate but these leaves appear randomly scattered up and down the stem’s length, and that means they aren’t in a whorl. Indian cucumbers have tiers of whorled leaves as do some loosestrifes. This plant is also called sharp leaved aster and grows to about a foot and a half tall. Something I didn’t know about the plant is how its leaves have a faint smell of spearmint when they’re crushed. Many thanks to blogging friend Kenneth Posner for that interesting bit of information.
Whorled wood aster is 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. I love the beauty of asters but I don’t like their message of summer’s passing, so when I stop and admire them I always feel a bit of wistfulness and wonderment that a season could pass so quickly.
Many flowers have a visible inner light but few shine it out as brightly as 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. Maybe the postal workers stand in awe of its amazing ethereal light, just as I do.
Flowers have spoken to me more than I can tell in written words. They are the hieroglyphics of angels, loved by all men for the beauty of their character, though few can decipher even fragments of their meaning. ~Lydia M. Child
