late August Wildflowers

Wildflower posts are bound to get shorter soon, but for now there’s still plenty to see.

 

Our native black eyed Susan (Rudbeckia hirta) can be found in all fifty states and all across Canada. It is believed that they got their start in the great prairies and moved to other locations from there. They were noted in Maryland in colonial times and became that state’s state flower. I saw my first one this year at the end of June and here they are, still blooming.

Blur vervain (Verbena hastata ) is almost done blooming. You can tell that by the way the flowers are at the tip of the flower stalk. They start at the bottom, a few at a time, and work their way up the stalk. Once done flowering the stalks look almost reptilian.

 

This is something I wasn’t expecting-a bladderwort growing in soil. Apparently, from what I’ve read, this aquatic plant will grow in soil if the conditions are agreeable, but what I don’t understand is how it gets any nutrition when it does. Bladders on its underwater leaves have small trap doors that open quickly to trap insects, making it a carnivorous plant, but if those underwater bladders are buried in soil, then how do they work?

 

This is a close up of the strange terrestrial bladderwort (Utricularia.) It looks like any other bladderwort.

 

Another thing that I never thought I’d see is chicory (Cichorium intybus) blooming in August, but here it is.

 

Burdock is another import that has escaped and is commonly seen on roadsides and in waste places. Its flowers aren’t real big and showy but they are beautiful. Once the flowers are finished the round, barbed seed heads that we all know so well appear. I read recently that burdock seed heads were the inspiration for Velcro. Unfortunately they can also act as snares and catch small birds that often aren’t able to free themselves.

Common mullein (Verbascum thapsus ) is known as a pioneer plant, meaning that it is often first to colonize burned or disturbed areas. Each plant can produce 100,000 or more seeds each year. Another name for it is flannel leaf because of its large, soft, fuzzy leaves. At one time the plant was thought to be useful in fighting leprosy and Pliny the Elder of ancient Rome used the warmed leaves as poultices for arthritis. Its tall persistent seed stalks really stand out in winter. These seed stalks were dipped in tallow and used as torches by Roman legionnaires. This plant is from Europe and is considered invasive.

 

The strange, brownish flowers of groundnut (Apios americana) remind me of the helmets once worn by Spanish explorers. Swollen underground stems on this vining plant form small tubers that look like potatoes but have three times the protein that potatoes do. Groundnuts were a very important food source for Native Americans and the Pilgrims survived on them when their corn supply ran out in 1623. Henry David Thoreau wrote that they tasted better boiled than roasted. The only thing keeping the groundnut from becoming a commercially viable food crop is the two to three years it takes for its tubers to form.

 Native hog peanut (Amphicarpaea bracteata ) flowers are small but beautiful. Like the groundnut in the previous photo the plant is a legume in the bean family.  Like a true peanut, after pollination some of its flowers bury themselves in the soil and form a small, edible, bean like seeds that give the plant its common name. Mice collect these seeds and store them in large caches that Native Americans used to search for. They can be eaten raw or cooked. The plant also forms inch long, pea-like, above ground pods that contain three or four inedible seeds.

Hog peanut is a strong, wiry vine that can cover large areas of forest floor and choke out other plants. It is also good a tripping up hikers.

I found this morning glory (Ipomoea) growing at the town landfill. I love its deep blue color but I find the ones that have more white in their throat, like “heavenly blue” more visually pleasing.

 Tansy (Tanacetum vulgare) is a European native that has been cultivated for centuries. 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 was used as such in colonial times. Dried tansy added to the straw in mattresses was said to keep bedbugs away. Most tansy plants are seen in gardens but it had naturalized itself in New England by 1785 and can still be found growing along roadsides like the one pictured was doing. The ancient Greeks grew tansy for medicinal use but it should be considered toxic.

Rabbit’s foot clover (Trifolium arvense) has appeared here a few times, but not bejeweled with dew like this one.

Flowers have an expression of countenance as much as men and animals. Some seem to smile; some have a sad expression; some are pensive and diffident; others again are plain, honest and upright, like the broad-faced sunflower and the hollyhock. ~Henry Ward Beecher
