Aquatics

I’m starting this post on aquatics with blue vervain (Verbena hastata,) only because I like its color. It isn’t a true aquatic but every time you find it there will be water very nearby. Blue vervain provides a virtual nectar bar for many species of bees including the verbena bee (Calliopsis verbenae.) Butterflies also love it. It likes wet soil and full sun and can reach 5 feet when it has both. I find it in wet ditches, on river banks and just about anywhere where the soil stays constantly moist.

Wild calla (Calla palustris) is also called water dragon or water arum, and it is a true aquatic. It is an arum like skunk cabbage or Jack in the pulpit, both of which also like wet places. I don’t know if I could say this plant is rare but it is certainly scarce in this area. It’s the kind of plant you have to hunt for, and you have to know its habits well to catch it in bloom. Like other arums its flowers appear on a spadix surrounded by a spathe. The spathe is the white leaf like part seen in the above photo. This plant is toxic and I’ve never seen any animal touch it.

I missed the tiny greenish white flowers this year. They grow along the small spadix and are followed by green berries which will ripen to bright red and will most likely be snapped up by a passing deer. This plant was in the green, unripe berry stage. One odd fact about this plant is how its flowers are pollinated by water snails passing over the spadix. It is thought that small flies and midges also help with pollination, because the odor from the blossoms is said to be very rank.

Pickerel weed is having a bad year and gone are the beautiful ribbons of blue flowers along the river’s banks. I’m not sure what is causing such a sparse bloom but I hope it rights itself because large masses of this plant in bloom can be truly spectacular.

One of the things that always surprises me about pickerel weed is its hairiness. I don’t expect that from a water plant. Its small blue / purple, tubular flowers on spikey flower heads will produce a fruit with a single seed. Once the flowers are pollinated and seeds have formed the flower stalk will bend over and drop the them into the water, where they will have to go through at least two months of cold weather before being able to germinate. If you see pickerel weed you can almost always expect the water it grows in to be relatively shallow and placid, though I’ve heard that plants occasionally grow in water that’s 6 feet deep.

I haven’t seen any berries yet but elderberries (Sambucus nigra canadensis) have bloomed well this year so we should have plenty. This is another plant that doesn’t grow in water but it grows as close as it can to keep its roots good and moist. This native shrub can get quite large and its mounded shape and flattish, off white flower heads make it very easy to identify, even from a distance.

A floating plant that is attached by roots to the pond or lake bottom is an aquatic, and that description fits floating hearts (Nyphoides cordata) perfectly. Floating hearts 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 are about the size of a common aspirin and resemble the much larger fragrant white water lily blossom. They grow in bogs, ponds, slow streams, and rivers. This flower was having trouble staying above water because it had rained and the water level had risen.

Forget me nots are not an aquatic plant but I keep finding them in very wet places. This one grew right at the edge of a pond so its roots must have been at least partially in water. The ground they grew in was also so saturated my knees got wet taking this photo. Many plants that are thought of as terrestrial are able to tolerate submersion in water and can live where they’re exposed regularly to water and from what I’ve seen, this is one of them.

Water lobelia (Lobelia dortmanna) is probably the rarest of all the aquatics that grow in this area. I still know of only one pond it grows in and there are only a handful of them there. I’ve read that the plant has the unusual ability of removing carbon dioxide from the rooting zone rather than from the atmosphere. It is said to be an indicator of infertile and relatively pristine shoreline wetlands. This year I saw only 4 or 5 plants in a small group. The small, pale blue or sometimes white flowers are less than a half inch long and not very showy. They have 5 sepals and the base of the 5 petals is fused into a tube. The 2 shorter upper petals fold up. I’ve read that the flowers can bloom and set seed even under water. True aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater) and this one has adapted well.

I saw a strange looking bubble which had ripples coming from it, as if it were moving. It was in a pond, just off shore.

Of course if you go looking for aquatic plants, you’re going to see dragonflies like this widow skimmer.

I’m also seeing lots of what I think are spangled skimmers this year. On this day all of them were watching the water.

Pipewort plants (Eriocaulon aquaticum) are also called hatpins, and this photo shows why perfectly. Pipewort plants have basal leaves growing at the base of each stem and the leaves are usually underwater, but falling water levels had exposed them here. Interestingly, this photo also shows the size difference between a floating heart, which is there in the center, and a standard water lily leaf, which you can just see in the top left. Floating hearts are tiny in comparison.

Pipewort stems have a twist and 7 ridges, and for those reasons it is called seven angle pipewort. The quarter inch diameter flower head that sits atop the stem is made up of minuscule white, cottony flowers. I think it’s interesting how their leaves can photosynthesize under water.

Sometimes it doesn’t matter if there are any flowers in view. The light is enough.

I saw what I thought was a pretty clump of grass right at the very edge of the river bank but when I looked closer, I saw that it wasn’t any grass that I had ever seen before and I think it is reed sweet-grass (Glyceria maxima,) which is invasive. It is native to Europe and Western Siberia and is a semi-aquatic, perennial grass with unbranched stems that get up to 8’ tall. There is a reddish tint on the lower parts of the stems. This plant towered up over my head but I can’t swear it had red on the stems because I have trouble seeing red. Reed sweet-grass invades wetlands and crowds out natives, and is not suitable for nesting. It is also a poor food source for our native wildlife.

Meadowsweet (Spirea alba) grows in the form of a small shrub and is in the spirea family, which its flowers clearly show with their many fuzzy stamens. It’s a common plant that I almost always find near water.

Meadowsweet flowers are fragrant and have a sort of almond-like scent. A close look shows that clearly, they belong in the spirea family. Before long their pretty purple cousins the steeple bushes will come along.

In my opinion swamp milkweed (Asclepias incarnata) is the most beautiful milkweed of all. It grows onshore but a few yards away from the water’s edge on land that rarely floods. Many insects were visiting it on this day. I know of only a single plant now, so I hope it produces plenty of seeds. The flowerheads always remind me of millefiori glass paperweights.

Swamp candles (Lysimachia terrestris) are not true aquatics but they do grow close enough to water to have their roots occasionally flooded. They are common along the edges of ponds and wetlands at this time of year. Their name comes from the way their bright color lights up a swamp, just as they did here.

Swamp candles have a club shaped flower head (raceme) made up of 5 petaled yellow flowers. 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 also often streaked with red and this is common among the yellow loosestrifes. Reddish bulbets will sometimes grow in the leaf axils. I’ve read that our native yellow loosestrifes were thought to have soothing powers over animals so people would tie the flowers to the yoke of oxen to make them easier to handle.

Pretty little sheep laurel (Kalmia angustifolia) will sometime grow in standing water but only when it rains and the water level rises. By choice they live right at the water’s edge. On the day I saw these I saw thousands of flowers blooming on the banks of a pond.

Here is a closer look at the flowers. Sheep laurel is part of the Kalmia clan, which in turn is part of the very large heath family, which includes rhododendrons, blueberries and many other plants. I know of only three Kalmias here and they are Mountain, Sheep and Bog laurel. The flowers of all three, though different in size and color, have ten spring loaded anthers which release when a heavy enough insect lands on the flower. It then gets dusted with pollen and goes on its way.

You can always tell that you’ve found one of the three Kalmias by looking at the outside of the flower. If it has ten bumps like those seen here you have found one of the laurels. Each bump is a tiny pocket that the tip of an anther fits into. If the flowers are anything but white it is either a sheep or bog laurel. If the flowers are white it’s a mountain laurel, though I’ve seen mountain laurels with pink flowers in gardens for the first time this year.

Fragrant white water lilies (Nymphaea odorata) are having a good year, I’m happy to say. They’re one of our most beautiful native aquatics. If you could get your nose into one you might smell something similar to honeydew melon or cantaloupe, but getting your nose into one is the tricky part.

I went to a local pond and saw what I thought were two-foot-tall white flowers on an island offshore. The pickerel weeds growing near the island told me the water could be up to six feet deep, so I certainly couldn’t wade out to them. My only choice was the zoom on my beaten-up old camera so I put it on the monopod and gave it a shot. When I looked at the photo I was stunned to see that the flowers weren’t white, they were pink. That was because they were rose pogonia orchids (Pogonia ophioglossoides,) a most rare and beautiful flower that I had been searching for in the wild for probably twenty years. And here they were, at a pond I had visited a hundred times. Why had I not seen them before? Because I had never come to this exact spot on the shore at this exact time of year before. That’s how easy it is to miss seeing one of the most beautiful flowers found in nature in bloom.

I’m sorry these are such poor photos but if you just Google “Rose Pogonia” you will see them in all their glory. This is a fine example of why, once you’ve started exploring and studying nature you feel that you really should keep at it, because you quickly learn that right around that next bend in the trail could be the most beautiful thing you’ve ever seen. I hope you have found that this is true in your own walks through nature.

Away from the tumult of motor and mill
I want to be care-free; I want to be still!
I’m weary of doing things; weary of words
I want to be one with the blossoms and birds.

Cool Water on a Hot Day

On Sunday some friends and I decided to take our kayaks out for the first time this season. The water in Wilson Pond in Swanzey was warm enough for a dip, in case a mishap should happen and one of us got wet. We started our journey by paddling past the island in the pond.

It was a beautiful day and the sun felt hot as we paddled, but luckily there was a stiff breeze that cooled us. Though welcome, it also made the water quite choppy and would blow your kayak across the water as if it were a sailboat if you stopped paddling.

Secluded coves and channels meant we could find some shade and get away from the wind for a while. The water in some of these channels is very shallow; I’m not sure you’d even get your knees wet if you walked them. Last year there were a lot of ducks here but on this day we didn’t see a single one.

Beavers had cut down many of the white birch trees along the shore but they left them behind and didn’t even eat the new twigs on their crowns, which seems odd behavior for a beaver. Some trees were hard to paddle around.

I’ve never seen any white water lilies in this pond but yellow pond lilies (Nuphar lutea) like to grow in coves where the water is relatively shallow and calm.

The seeds of the yellow pond lily plant 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.

Native pickerel weed (Pontederia cordata) blossomed in small colonies just off shore. If you see pickerel weed you can expect the water it grows in to be relatively shallow and placid. These examples were only about two feet high but I recently saw others that were as tall as a great blue heron.  I didn’t know that they grew so tall.

Pickerelweed’s common name comes from the pickerel fish because they were once thought to breed only under its leaves. Each of the small, tubular flowers on the spikey flower heads will produce a fruit with a single seed. Once the flowers are pollinated and seeds have formed the flower stalk will bend over and drop the seeds into the water, where they will have to go through at least two months of cold weather before being able to germinate. Ducks and muskrats love the seeds and deer, geese and muskrats eat the leaves. Though humans can eat the seeds and new spring shoots of this plant there is no record that I can find of Native Americans using it for food.

Maleberrry (Lyonia ligustrina) shrubs look much like a blueberry, even down to their flowers, but these flowers are much smaller than those of blueberry. I’d guess barely half the size of a blueberry blossom. The two shrubs often grow side by side and look so much alike that sometimes the only way to tell them apart is by the maleberry’s woody brown, 5 part seed capsule. These seed capsules stay on the shrub in some form or another year round and are helpful for identification, especially in spring when the two shrubs look nearly identical.

I’ve included this photo of the maleberry’s seed capsules that I took earlier so you could see what they look like. They are very hard and woody and appear near the branch ends.

Mad dog skullcap (Scutellaria lateriflora) plants grow in great bunches along the shoreline. 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.

Swamp roses (Rosa palustris) bloomed in great numbers on the hummocks along the shoreline but I had trouble getting close to them. The 2 inch flowers are very fragrant and though the plant prefers wet to moist soil it will also grow in dry ground. It would be an excellent choice for a home pond or near a stream.

Bur reed is another plant found growing 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 female flowers of bur reed are 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.

Pipewort (Eriocaulon aquaticum) isn’t common in this area and doesn’t grow in this pond, but I’ve included it because it’s an unusual aquatic that isn’t often seen. In fact, I know of only two ponds that it grows in. The plants 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 minuscule 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, aquaticus, is Latin for a plant that grows in water, so what you are left with is a wool-topped stem growing in water, and that’s exactly what pipewort is. I’ve found that its flowers are close to impossible to get a good photo of.

When I found a new spot for pipewort plants this year I also found a new plant that I’d never seen; water lobelia (Lobelia dortmanna.)  I can’t speak for its rarity, but I’ve never seen it in any pond I’ve visited. It’s said to be a more northern species, so that could be why. I’ve read that the plant has the unusual ability of removing carbon dioxide from the rooting zone rather than from the atmosphere. It is said to be an indicator of infertile and relatively pristine shoreline wetlands.

The small, pale blue or sometimes white flowers are less than a half inch long and not very showy. They have 5 sepals and the base of the 5 petals is fused into a tube. The 2 shorter upper petals fold up. I’ve read that the flowers can bloom and set seed even under water. The seed pods are said to contain numerous seeds which are most likely eaten by waterfowl.

Cattails (Typha latifolia) formed an impenetrable wall and soared overhead in some places along the shoreline. They must have been 8 feet tall or more.

As the old saying goes all good things must come to an end and before we knew it, it was time to turn for home. I’ve found that an hour or so in a kayak is about all my back can take, but what a fun filled hour it can be. It’s an excellent way to get close to aquatic plants.

We are but a speck in the universe
Oh, but what a lucky speck to be.

More Early July Flowers

Our aquatic plants have started blooming here in the southwestern part of New Hampshire and queen among them, at least in my opinion, is the fragrant white waterlily (Nymphaea odorata.) I happened to be with someone recently who crawled out on a fallen tree to smell one of these beauties. When I told him that people said they smelled like honeydew melons he agreed. Sort of-it was a hard fragrance to describe, he said, but a pleasant one.  I’m happy just seeing them; I like the golden fire that burns in their center.

Pickerel weed (Pontederia cordata) is another aquatic that has small purple, tubular flowers on spikey flower heads that produce a fruit with a single seed. Ducks and muskrats love the seeds and deer, geese and muskrats eat the leaves. If you see pickerel weed you can almost always expect the water it grows in to be relatively shallow and placid, though I’ve heard that plants occasionally grow in water that’s 6 feet deep. It’s a plant that often forms large colonies.

A small sampling of what was a very large colony of pickerel weed. Native Americans washed and boiled the young leaves and shoots and used them as pot herbs. They also ground the seeds into grain. The plant gets its name from the pickerel fish, which is thought to hide among its underwater stems.

One of my favorite aquatics is American burr reed (Sparganium americanum,) more for its quirky appearance than for any other reason. Its round, spiky female flowers grow at the bottom of the stem and the male flowers with yellow stamens above them. Burr reed usually grows right at the edge of ponds and rivers in waterlogged soil but it will sometimes grow in still water. Ducks and other waterfowl love the seeds.

Purple loosestrife is an invasive that came over from Europe in the ballast of a cargo ship in the 1800s. The beach sand ballast, loaded with purple loosestrife seeds, was originally dumped on Long Island, New York. The seeds grew, the plant spread and now it covers most of Canada and all but 5 of the lower Untied States. It likes wet, sunny meadows.

Purple loosestrife chokes out native plants and forms monocultures. These colonies can be so large that finding a single plant like the one pictured above is becoming very difficult. I read of an experiment going on in Dublin, a town east of here, in which the New Hampshire Department of Agriculture is releasing European beetles to feed on purple loosestrife. The thought is that the beetles will control the plant but my question is, suppose they do control the plant and suppose one day there isn’t any more purple loosestrife. What will the beetles feed on then, native plants? Will we be any better off?  I think we need to be very careful what we wish for.

Though it is much hated you can’t deny the beauty of purple loosestrife. I’ve worked for nurseries and have had people come in wanting to buy “that beautiful purple flower that grows in wet areas.”

Mad dog skullcap (Scutellaria lateriflora) gets its 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. 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.

There is powerful medicine in both mad dog or 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.

Meadowsweet (Spiraea Ulmaria) is another plant that I look for at the water’s edge, though it doesn’t usually grow close enough to get its feet wet. It grows in the form of a small shrub and is in the spirea family, which its flowers clearly show with their many fuzzy stamens. The flowers are fragrant and have a sort of almond-like scent. This plant was one of three considered most sacred by the Druids and has been used medicinally for many thousands of years. Here in America it is an introduced invasive, but little is heard about it and nobody seems to mind.

NOTE: The scientific name I meant to use for this plants is Spirea alba.

I find soapwort (Saponaria officinalis) growing along river banks. The plant gets its common name from the way the chopped and boiled leaves produce a soapy lather that is particularly good at removing grease. This plant is a native of Europe and is thought to have been brought over by colonists to be used as a soap substitute. It is said to be especially useful for waterproofing wool, and museum conservators use it for cleaning delicate fabrics that can be harmed by modern soaps.

Joe Pye weed (Eutrochium purpureum) is just coming into bloom and I like its dusty rose pink color with the beautiful blue of vervain. I found them on the rocky banks of the Ashuelot River.

Canada thistle (Cirsium arvense) isn’t covered with sharp spines like the larger bull thistle (Cirsium vulgare) that most of us have tangled with. Though it does have spines along the leaf margins and stem, they are quite small. Despite its common name the plant is actually a native of Europe but has spread to virtually every country in the northern hemisphere. It has a deep and extensive creeping root system and is nearly impossible to eradicate once it gains a foothold. For that reason it is considered a noxious weed in many states.

Along with lilacs and peonies, the common orange daylily (Hemerocallis fulva) is a plant you’ll find growing near old stone cellar holes out in the middle of nowhere and along old New England roads. It is also found in cemeteries often planted beside the oldest graves. It is one of those plants that were passed from neighbor to neighbor and spread quickly because of it. It is also very tough; my brother used to mow his when they finished blooming and they still came back and bloomed year after year. It is both loved for being so easy to grow and hated for being so common.

This plant was introduced into the United States from Asia in the late 1800s as an ornamental and plant breeders have now registered over 40,000 cultivars, all of which have “ditch lily” genes and all of which have the potential to spread just like the original has. If you find yourself doing battle with a particularly weedy daylily, no matter the color, there’s a very good chance that the common orange is one of its parents.

Phlox whispered that fall is on the way but I didn’t want to hear it. It seems like just yesterday that I was taking photos of spring beauties.

Herb Robert is a geranium that has never appeared on this blog because I’ve never found it in the wild until just recently on the banks of the Ashuelot River in Surry, which is north of Keene. My question, once I had identified it, was: Robert who? As it turns out Robert was a French monk who lived in 1000 AD and cured many people’s diseases using this plant, and that leads to another common name: Saint Robert’s Herb. If you crush its leaves they are said to smell like burning tires, so yet another common name is stinky Bob.

A very curious fact about this plant is how many people, scientists included, have discovered that it grows most abundantly in areas that have high levels of radiation. It is thought to absorb the radiation from the soil, break it down and disperse it. If I had a Geiger counter I’d go back and check the bedrock outcrop that I found it growing on.

Friends let their radishes go to seed this year and among the rows of plain white flowers was a beautiful pink one. Since Henry David Thoreau instilled a spirit of nonconformity in me when I read his words as a boy, I was happy to see this plant breaking ranks and doing its own thing. Many of the plants found in nurseries are those that have done the same.

It’s not what you look at that matters, it’s what you see. ~Henry David Thoreau
