We’ve had some hot weather lately and that always makes me want to be near water, and of course when I’m near water I can’t help noticing the plants that grow there. Cattails (Typha latifolia) are the easiest to see, sometimes towering to 6 or 8 feet tall. They can grow faster than fertilized corn and can create monocultures by shading out other plants with their dense foliage and debris from old growth. They are very beneficial to many animals and birds and even the ponds and lakes they grow in by filtering runoff water and helping reduce the amount of silt and nutrients that flow into them. Scientists have recorded cattail marshes travel up to 17 feet in a year with prime conditions just by sending out new shoots. Of course, that doesn’t account for all the new plants that grow from seed.
Cattail flowers start life with the female green flowers appearing near the top of a tall stalk and the fluffy yellowish green male pollen bearing flowers above them. Once fertilized the female parts turn from green to dark brown and the male flowers will fall off, leaving a stiff pointed spike above the familiar cigar shaped seed head. Cattail flowers are very prolific; one stalk can produce an estimated 220,000 seeds. Cattails were an important food for Native Americans. Their roots contain more starch than potatoes and more protein than rice, and native peoples made flour from them. They also ate the new shoots in spring, which must have been especially welcome after a long winter of eating dried foods. They had uses for every part of this plant; even the pollen was harvested and used in bread.
Though Native Americans used blue flag irises medicinally its roots are considered dangerously toxic and people who dig cattail roots to eat have to be very careful that there are no irises growing among them, because the two plants often grow side by side. Natives showed early settlers how to use small amounts of the dried root safely as a cathartic and diuretic, but unless one is absolutely sure of what they’re doing it’s best to just admire this one. This photo is of the last one I saw blooming this year.
Bur reed grows just off shore but I’ve also found it growing in wet, swampy places at the edge of forests. Bur reeds can be a challenge to identify even for botanists, but I think the one pictured is American bur reed (Sparganium americanum.) There are two types of flowers on this plant. The smaller and fuzzier staminate male flowers grow at the top of the stem and the larger pistillate female flowers lower down.
The male staminate flowers of bur reed look fuzzy from a distance and kind of haphazard up close.
The female bur reed flowers are always lower down on the stem and look spiky rather than fuzzy. They’re less than a half inch across. After pollination the male flowers fall off and the female flowers become a bur-like cluster of beaked fruits that ducks and other waterfowl eat. The flowers of bur reed always remind me of those of buttonbush. This plant can colonize a pond very quickly. I know of one small pond that started with 2 or 3 plants a few years ago and now nearly half the pond is being choked out by them.
The seeds of the yellow pond lily plant (Nuphar lutea) were a very valuable food source to Native Americans, who ground them into flour. They also popped them much like popcorn, but unless the seeds are processed correctly they can be very bitter and foul tasting. The plant was also medicinally valuable to many native tribes. There were tiny flies crawling over most of the blossoms I saw on this day.
Mad dog skullcap (Scutellaria lateriflora) plants grow in great bunches along the shorelines of lakes and ponds. These small blue-violet flowers get their common name from the way that the calyx at the base of the flowers look a bit like a medieval helmet, called a skull cap, and how the plant was once thought to cure rabies because of its anti-spasmodic properties. Though it doesn’t cure rabies there is powerful medicine in this little plant so it should never be eaten. When Native Americans wanted to go on a spirit walk or vision quest this was one of the plants they chose.
Mad-Dog Skullcap has the smallest flowers among the various skullcaps and they always grow in pairs in the leaf axils. Another skullcap, marsh skullcap (Scutellaria galericulata,) looks very similar and the two are difficult to tell apart. Both grow in full sun on grassy hummocks at the water’s edge, but the blossoms of mad dog skullcap are slightly smaller than those of marsh skullcap.
Some of the aquatic plants that I like to see up close grow far enough out in the water to have to be photographed from a boat or by swimming out to them with a waterproof camera. If you really want to challenge your photographic skills, try photographing aspirin sized flowers from a kayak that you can’t keep still.
Swamp roses (Rosa palustris) are about as big as an Oreo cookie and grew where I kayaked in great numbers. This rose, like many other plants, grows on hummocks and small islands but it can grow in drier locations as well. I saw a lot of swamp milkweed too, but I couldn’t get close enough for a photo.
One day I saw a couple of Canada goose families eating cherries from cherry trees that had bent low over the water. I didn’t know that they did this.
The adults seemed to be trying to teach the goslings how to get at the cherries but the little birds didn’t have the neck stretch it took to reach the fruit.
What I believe is creeping spike rush (Eleocharis macrostachya) isn’t a rush at all; it’s a sedge, so I’m not sure why it’s called a rush. As sedges go this one is very small; just a spiked stem with a brushy little flower head on top and a couple of basal leaves. It likes to grow in standing water at pond and lake edges, just off shore but I’ve read that it will also grow in ditches, vernal pools, and wet meadows.
The flower head of this sedge is called a spikelet and it is about a half inch long. The cream colored oval parts are the male flowers and the wispy white feathery bits are the female flowers. There are several sedges in this family that look nearly identical so I could be wrong about its name. According to the book Grasses: An Identification Guide by Lauren Brown, the only way to tell them apart is by their tiny fruits, and I doubt that I could even see them.
Dwarf St. John’s wort (Hypericum mutilum) is a small, bushy plant that gets about ankle high and has flowers that resemble those found on its larger cousin, St. John’s wort. A noticeable difference, apart from their small size, is how the flowers lack the brown spots often found on the petals of the larger version. Since the plants often grow right at the water’s edge, you usually have to get wet knees to get a good photo of them.
One of the bonuses of looking for aquatics is that you see a lot of dragonflies, like this male common whitetail dragonfly. This dragonfly rests on twigs and grasses near the water, and sometimes on the ground. I haven’t seen one on the ground but I have seen them on stones. This isn’t a very good shot but he only perched long enough for one click of the shutter.
If only narrow leaved speedwell (Veronica scutellata) would grow at the water’s edge. Instead it grows in standing water in a very wet but sunny meadow and by the time I was finished taking its photo my feet were soaked. How odd it seems that a meadow could be in full sun all day every day and still be so wet, but we have had a lot of rain. The plant is also called marsh speedwell and that makes perfect sense.
Here’s a closer look at the flower of the narrow leaved speedwell. Small blue flowers with darker blue stripes are typical of speedwells, but these can also be white or purple. They are very small and only have room for two stamens and a needle-like pistil. The plants obviously love water because there were many plants growing in this very wet area. If you were looking for a native plant for the shallow edges of a water garden it might be a good choice. Though most speedwells we see here are non-native, this one belongs here. Like lobelias, Native Americans used plants in the veronica family to treat asthma.
Native swamp candles (Lysimachia terrestris) are one of our yellow loosestrifes that bloom at about the same time as the yellow whorled loosestrife that I spoke of in my last post. But whorled loosestrife likes dry ground and swamp candles like to have their feet wet most of the time. They are common along the edges of ponds and wetlands at this time of year. I’ve even seen them growing in standing water.
Swamp candles stand about 1-2 feet tall and have a club shaped flower head (raceme) made up of 5 petaled yellow flowers. With darker vegetation behind them swamp candles really live up to their name.
Though they are very hard to see in this example because of the bright light each yellow petal of a swamp candle flower has two red dots at its base that help form a ring of ten red dots around the five long stamens in the center of the flower. The petals are often streaked with red and the flowers are about half the size as those of whorled loosestrife.
Queen of all the aquatics in my opinion is the very beautiful fragrant white water lily (Nymphaea odorata.) A bright yellow fire burns in the center of its snow white petals, and its fragrance is much like that of honeydew melon. There are some flowers that are so beautiful I want to just sit and gaze at them all day, and this is one of them. To see a pond full of them is breathtaking.
It is life, I think, to watch the water. A man can learn so many things. ~Nicholas Sparks

Late August Flowers

This crooked stem aster (Symphyotrichum prenanthoides) is one of the first blue asters I’ve seen this year. I found a small colony growing in a sunny spot in the woods, surrounded by many other white asters. I don’t usually try to identify asters but the one inch diameter light blue flowers and zigzagging stems made this one easier than most. The Native American Iroquois tribe used this plant medicinally to treat fevers and other ailments.
Native large leaved aster (Eurybia macrophylla) is another aster that is relatively easy to identify because of its big heart shaped leaves. The plant spreads by rhizomatous roots and can form very large colonies, especially on hillsides as these examples were. Its leaves are often as big as my hand and they can take a lot of shade. The plant seems to be blooming well this year in spite of drought so I’m assuming that they don’t mind dry soil. They don’t like being disturbed by human activity so I don’t see them close to roadsides often. These were separated from the road by a wide drainage ditch.
Most of the flowers that I find on large leaved asters are white but they can also be light blue or lavender. As in many asters the ray florets are irregularly spaced around the central disc florets. The tubular disc florets turn from yellow to orange-red as they age and then change to dark red before finally turning brown.
If the square stems and tufts of tiny pink / purple flowers in the leaf axils don’t ring a bell, then one sniff of a crushed leaf will tell you immediately that this plant is wild mint (Mentha arvensis.) Mint has been used by man since the dawn of time and Pliny, Hippocrates, Aristotle and Charlemagne each wrote of its virtues. Each time we see it we are seeing one of mankind’s earliest memories. I find it growing in the tall grass at the edge of the forest and I always have to smell it.
I never thought of speedwell as an aquatic plant until I met the narrow leaved speedwell (Veronica scutellata.) It is also called marsh speedwell and that makes perfect sense, because it grew in standing water in full sun at the edge of a field last year. This year there was no standing water but the soil was still saturated. Though most speedwells we see here are non-native, this one belongs here. Like lobelias, Native Americans used plants in the veronica family to treat asthma.
Small blue flowers with darker blue stripes are typical of speedwells, but these can also be white or purple. They are very small and only have room for two stamens and a needle-like pistil. The plants obviously love water because there are many plants growing in this very wet area. If you were looking for a native plant for the shallow edges of a water garden it might be a good choice.
Tiny eastern forked blue curls (Trichostema dichotomum) has flowers that might make a half inch across on a good day, so it’s a challenging plant to photograph. One unusual thing about the flower, other than its unique beauty, is its four long, arching stamens that dust bees with pollen when they land on its lower lip. This plant is an annual that grows new from seed each year. It seems to like sandy soil and I find it growing along river banks and sometimes roadsides. It’s a beautiful little thing that’s worth looking for, but getting a good photo of it is tricky. It took 8 tries to get this one.
Forked blue curl plants barely reach your ankle. The entire plant pictured could have easily fit inside a coffee mug.
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. Even after they open they still look like they are in the bud stage, so you have to look at them closely. 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.
This is all we see of a pilewort flower when it opens. It is made up of many disc florets which are pollinated primarily by wasps and hornets. Once they go to seed they will float away on the wind much like dandelion seeds. 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.
The drought we find ourselves in is presenting many problems but also a few opportunities. Pipewort (Eriocaulon aquaticum) usually grows in ankle deep standing water but the water of this pond had receded enough so that I could walk right up to the plants shown without taking my shoes off. Since they grow with their lower stems submerged I’ve never been able to see the entire plant, but now I could.
I’m not sure what I expected to see but the leaves surprised me. With leaves the pipewort looked just like many other plants but its basal leaves normally grow underwater, which seems a little strange. I’m guessing that they must still get enough sunlight through the water to photosynthesize. The stem has a twist to it with 7 ridges and because of that some call it seven angle pipewort.
Most pipeworts grow just offshore in the mud and send up a slender stalk that is topped by a quarter inch diameter flower head made up of very tiny white, cottony flowers. Eriocaulon, the first part of pipewort’s scientific name, comes from the Greek erion, meaning wool, and kaulos, meaning plant stem. The second part of the scientific name, aquaticum, is Latin for a plant that grows in water, so what you have is a wool-topped stem growing in water, which of course is exactly what pipewort looks like. Pipewort is wind pollinated. It is also called hat pins, for obvious reasons.
Native wild cucumber (Echinocystis lobata) is a late summer blooming vine that climbs on shrubs and trees and hangs on using tendrils like a grape. It likes to grow in sandy soil and prefers partial shade over full sun. The flower spikes (Racemes) grow to 6 inches or more all along the main stem. These plants are annuals and grow from seed each year.
The greenish white, star shaped male flowers of wild cucumber have 6 petals that are twisted slightly. The female flowers are yellowish green and not at all showy. They grow at the base of the male flower stems. There is usually only one female flower for every 5 or 6 male flowers, which is why there are so few fruits seen on each vine.
The spiny, 2 inch long fruits of the wild cucumber have a watermelon shape. Though the spines look menacing they are quite soft and children have been throwing them at each other for as long as I’ve been around. The fruit is not edible. The example shown here hadn’t grown to full size yet.
Little native blue toadflax (Nuttallanthus canadensis) has been blooming since May and is one of our longest blooming wildflowers. This plant seems to like sunny, dry, sandy waste areas or roadsides because that’s where I always find it growing. It’s always worth getting down on my hands and knees to admire its tiny but beautiful blue / purple flowers. They sparkle like sugar candy in the sunlight.
Last year the Town of Swanzey cut down all the plants and shrubs along a short stretch of the Ashuelot River and one of those plants was the chicory (Cichorium intybus) in the above photo. It gets mowed regularly now, so I was surprised to see a normal size flower on a plant no more than three inches tall. It looks a little stressed, whether from drought or being mowed I don’t know but it’s a beautiful flower, and stronger than I ever knew.
Beauty does not linger; it only visits. Yet beauty’s visitation affects us and invites us into its rhythm; it calls us to feel, think and act beautifully in the world: to create and live a life that awakens the beautiful. ~ John O’Donohue
