Posts Tagged ‘Common Bladderwort’

Our beautiful fragrant white water lilies (Nymphaea odorata) have just started to bloom and that always makes me want to show you our aquatics, so off I went to search our rivers, ponds, and ditches for all the plants that like wet feet.

Growing in the wet mud at the edge of a pond was a plant I’d never seen before; the lance leaved violet (Viola lanceolata.) It is also called the bog white violet or strap leaved violet, for obvious reasons. The plant needs a wet, sunny habitat, preferably one that floods and then dries out. It is listed as present in 8 out of the 10 counties in New Hampshire but though I’ve been on a lot of pond shores, I’ve never seen it. It is said to be rare in Vermont.

At first the flowers look like any other white violet but then you notice that it has no hairs on the side petals like other violets. The flowers nod on stems that can be as much as 6 inches long and both the bottom and side petals can have purple veining. This little plant only blooms for three weeks.

What makes the lanced leaved violet easy to identify is its leaves, which can be very long indeed. They are said to be 3-5 times longer than they are wide but I think this one exceeded that.

Wild calla (Calla palustris) isn’t at all common here but you can find them. I’ve been roaming around swamps and backwaters for 50 years and I’ve found them just twice. Though it isn’t thought to be rare in New Hampshire it is said to be a more northern species, so that could explain why I never see it. It’s also called water arum and is in the same family as Jack in the pulpit and other arums. Like jack in the pulpit the flowers appear on a spadix surrounded by a spathe. The spathe is the white leaf like part seen in the above photo. The plant is toxic so it should never be eaten. From what I’ve seen even animals won’t eat it. There are deer all over the swamp it grows in but not a leaf had been munched.

The flowers are tiny and greenish white, and grow along the spadix. They will be followed by green berries which will ripen to bright red and will most likely be snapped up by a passing deer. 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. The spot where I found these plant is wet most of the time but it does dry out occasionally.

I think this one is ribbon leaved pondweed (Potamogeton epihydrus.) If so it has two types of leaves; submerged leaves which are ribbon like, thin and transparent, and surface leaves which are said to be broad and elliptical. Since I’d call these leaves more long and narrow than broad and elliptical the jury is still out, even though they do look like the photos I’ve seen. In any case it is a common plant that I find in the river more than in ponds.

You might make a friend or two when you walk along the shoreline.

Or you might get lost in the ever changing patterns made by tree pollen floating on the surface. It’s a good year for pollen. Just ask any allergy sufferer.

Unless you have a boat you don’t get this kind of photo of the yellow pond lily plant (Nuphar lutea) because they usually grow a few yards from shore, but since we’re so dry right now though I found this one right at the water’s edge. The seeds of this 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.

Here’s a rare top view of the yellow pond lily blossom. These plants like to grow in protected coves where the water is relatively shallow and calm but you’ll get your feet wet getting to it.

Common bladderwort (Utricularia macrorhiza) normally floats but when it’s ready for dormancy its bladders fill with water and it sinks, and I find it in the mud at the edge of a pond. Its flowers are much larger than those of floating bladderwort, maybe a half to an inch long, and though this shot isn’t very good they’re easier to get a photo of when they aren’t floating.

Common bladderwort can be distinguished from other bladderworts by the spur on the flower. The name bladderwort comes from the small inflated sacs on the plant’s roots that open to trap aquatic organisms. There are tiny hairs on the bladder’s trap door which are very sensitive. When an aquatic organism touches these hairs the door opens, the organism is sucked inside and the door closes, trapping it. This all happens in about 5 milliseconds and is one of the fastest plant movements ever recorded.

I’ve been very lucky finding plants I’ve never seen before this year and here is another. There is a swamp where I work and in early spring I saw hundreds of small round, scalloped edged leaves growing on a few of the hummocks there. I wasn’t sure what they were so I watched them for weeks and finally, tall stalks with purple buds shot up from the leaves. Of course I started looking in guide books for purple flowers but that wasn’t it; when they opened they were yellow with orange centers and that led me to roundleaf ragwort (Packera obovata.)

The leaves aren’t round but they do start out that way in spring.

Stem leaves are very different.

Nurseries are selling round leaved ragwort but you’ll need to keep its feet wet and its head in the sun, which is a tall order for most gardens. It is said to spread rapidly and I can attest to that because I walked by the spot where it grows many times and for years didn’t see it. It is also called roundleaf groundsel, running groundsel, and squaw weed. Though its leaves are said to be toxic they were used in a tea by Native Americans and early settlers to ease childbirth. It was also used to treat lung ailments.

Blue flag irises are native, but yellow flag irises are not. I saw a few clumps of yellow flag iris (Iris pseudacorus) growing on the river bank a few years ago and what was a few clumps has now become a small colony.  I’ve searched for this plant for many years and found it only in one other spot in the woods by a pond that was very difficult to get to, but now here it is, right along the shoreline in full view.

This iris is a native of Europe and was introduced in the mid-1800s as a garden plant. Of course it escaped and began to naturalize and was reported near Poughkeepsie, New York in 1868 and in Concord, Massachusetts in 1884. Today it considered highly invasive and its sale and distribution is banned in New Hampshire, though in my experience it is still a rarity in this part of the state. It’s a beautiful flower but now I do wonder what the banks of the river might look like in 50 years. The plant is useful in certain ways; it is used in sewage treatment and is known to be able to remove metals from wastewaters, so maybe we could use them for that. 

I like the fern like leaves of wild chervil (Anthriscus sylvestris) which grows along streams. Wild chervil is thought to have come over from Europe in wildflower seed mixes. It has been growing in this area since the early 1900s and is considered a noxious weed in places. Wild chervil contains chemical compounds which have been shown to have anti-tumor and anti-viral properties. It isn’t the same plant as cultivated chervil used to flavor soups though, so it shouldn’t be eaten. In many places it is called cow parsley. On this day it was almost ready to bloom but it hadn’t yet.

Narrow leaved speedwell (Veronica scutellata) grows in standing water in a very wet but sunny meadow but luckily this day the water had dried up due to lack of rain. It might seem odd that a meadow could be in full sun all day every day and still be so wet, but there is usually standing water here. The plant is also called marsh speedwell and that makes perfect sense.

Here’s a not very good 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 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.

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 and fortunately I know a pond or two that fits that description. There are many other aquatics that haven’t bloomed yet, so we’ll be visiting the water again.

Thanks for stopping in. Happy first day of summer!

We’ve reached that point where you can’t walk through a field, drive down a road, or visit a forest without seeing flowers, because at this time of year they are everywhere. It is high summer and though I love spring I don’t see how any other season could be called more beautiful than this one.

Canada thistle (Cirsium arvense) blooms in the tall grass of unmown meadows. It isn’t covered with sharp spines like the larger bull thistle (Cirsium vulgare) that most of us have tangled with, but it does have small spines along the leaf margins and stem. 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.

Noxious weed or not I like the flowers of Canada thistle. In a way they remind me of knapweed, which is another noxious weed. The plant isn’t considered invasive here in New Hampshire but it is on the watch list. Where I find them growing they haven’t spread at all, and in fact this year there were fewer plants than last year.

Pretty little fringed loosestrife (Lysimachia ciliata) is the last of the native yellow loosestrifes to bloom in this area. Great colonies of the knee high plant can be found along roadsides and wood edges, and along waterways. It might be confused with whorled loosestrife (Lysimachia quadrifolia) if the two plants bloomed at the same time, but in this area fringed loosestrife blooms later. The flowers on fringed loosestrife are about the size of a quarter and nod to face the ground. On whorled loosestrife they face outward. The leaf arrangements on the two plants are also very different.

Fringed loosestrife gets its common name from the fringe of hairs on its leafstalks, but sometimes the flower petals are also fringed like they are on this example. It’s a cheery, pretty plant that often gets overlooked because there is just so much in bloom at this time of year. The flowers of fringed loosestrife are unusual because of the way they offer oils instead of nectar to insects. The oils are called elaiosomes and are fleshy structures that are attached to the seeds of many plant species. They are rich in lipids and proteins. Many plants have elaiosomes that attract ants, which take the seed to their nest and feed them to their larvae. Trout lily is another plant with elaiosomes.

Though many people think the flowers are where the name fringed loosestrife comes from it is actually from the fine hairs that line the leaf stalks (petioles.) The ciliata part of the scientific name means “fringed with hairs,” and so they are. Native Americans used all of our yellow loosestrifes medicinally for various ailments, usually in the form of tea.

No matter how many times I see the Allegheny monkey flower (Mimulus ringens) I don’t see a monkey, but whoever named it obviously did. This plant gets about knee high and likes to grow in wet, sunny places, and isn’t all that common. I usually have a hard time finding it.

Allegheny monkey flowers have square stems and are also called square stemmed monkey flowers. I didn’t know at the time I saw this flower that it had so much moisture on it. That’s odd because it was a warm sunny day and I wonder if it was sweating. The throat of this flower is partially closed and bumblebees are one of the few insects strong enough to pry it open to get at the nectar. Native Americans and early settlers sometimes used the leaves as an edible green.

Vervain (Verbena hastata) is described as having reddish blue or violet flowers but I see a beautiful blue color. Somebody else must have seen the same thing, because they named the plant blue vervain. Vervain can get quite tall and has erect, terminal flower clusters. The plant likes wet places but even though we’ve had many inches of rainfall this year, I had a hard time finding it.

Vervain flowers are quite small but there are usually so many blooming that they’re easy to spot. The bitter roots of this plant were used medicinally by Native Americans to relieve gastric irritation, as an expectorant, and to induce sweating. The seeds were roasted and ground into a flour or meal by some tribes, and the flowers were dried and used as snuff to treat nose bleeds. Natives introduced the plant to the European settlers and they used it in much the same ways.

I used to see quite a lot of floating bladderwort (Utricularia gibba,) but I haven’t seen any in the last two years. Instead I’m now finding common bladderwort (Utricularia macrorhiza.) This plant also floats but when it’s ready for dormancy its bladders fill with water and it sinks, and I find it in the mud at the edge of a pond. Its flowers are much larger than those of floating bladderwort and though this shot isn’t very good they’re easier to get a photo of when they aren’t floating.

Common bladderwort can be distinguished from other bladderworts by the spur on the flower. The name bladderwort comes from the small inflated sacs on the plant’s roots that open to trap aquatic organisms. There are tiny hairs on the bladder’s trap door which are very sensitive. When an aquatic organism touches these hairs the door opens, the organism is sucked inside and the door closes, trapping it. This all happens in about 5 milliseconds and is one of the fastest plant movements ever recorded.

Pipsissewa (Chimaphila umbellata) grows in large colonies and is easy to find because of its shiny green leaves that shine winter and summer and last up to 4 years. Like other wintergreens it likes dry, sandy, undisturbed soil in pine forests. Pipsissewa was once used as a flavoring in candy and soft drinks, including root beer. Its name is fun to say. It’s a Native American Cree word meaning “It-breaks-into-small-pieces.” This is because it was used as a treatment for kidney stones and was thought to break them into pieces.

Pipsissewa flowers often show a blush of pink. Five petals and ten chubby anthers surrounding a plump center pistil make it prettier than most of our other native wintergreens. Pipsissewa and some other native wintergreens form a symbiotic relationship with the mycelium of certain fungi in the soil and are partially parasitic on them through a process called myco-heterotrophy. This means that, even though they photosynthesize, they supplement their diet with nutrients taken from fungi. That explains why they will only grow in certain places, much like native orchids.

Shasta daisies are blooming in gardens everywhere now. The Shasta daisy was developed by plant breeder Luther Burbank over 100 years ago and was named for the white snow of Mount Shasta. These plants are a hybrid cross of the common roadside ox-eye daisy and an English field daisy called Leucanthemum maximum. They are one of the easiest perennials to grow and, other than an occasional weeding, need virtually no care. Dwarf varieties are less apt to have their stems bent over by heavy rains.

My favorite part of the Shasta daisy flower is the spiral at its center, because it makes me wonder. Nature uses the spiral over and over; it’s in a snail’s shell, our galaxy is a spiral and spirals are even in our DNA. Horns, teeth, claws, and plants form spirals. Pine cones and pineapples have spiral scales and if you make a fist and look at it from above, it forms a spiral. Mathematically, the spiral in a nautilus shell is the same as that found in a spiral galaxy. The spiral also represents infinity, starting at a single point and revolving outwardly until the end of the universe. Because of this, the spiral is said by some to be a pathway to the afterlife. All of that is right here in a daisy, and that’s probably why Deepak Chopra said “If you really see a daisy, you see from here to infinity.”

Non-native rabbit’s foot clover (Trifolium arvense) is short enough to be forced to grow right at the edge of the road if it wants to get any sunshine, so the roads look like they have been festooned with fuzzy pink ribbons for a while each summer. It’s an annual plant that grows new from seed each year and the seedlings must be tough, because they don’t seem to mind being occasionally run over, or the poor dry soil found along the road side. In fact they seem to thrive in it; I see more plants each year. The plant is originally from Europe and Asia.

One of the things I like most about native pineapple weed (Matricaria discoidea) is the way a child’s face will light up and break into a smile when they crush it and smell it. Usually when I tell them that it smells like pineapple they don’t believe it, so it’s a surprise. The conical flower heads are easiest to describe by saying they’re like daisies without petals, or ray florets. The flowers are edible and can be used in salads, and the leaves are also scented and have been used to make tea. The plant was used by Native Americans in a tonic to relieve gastrointestinal upset and fevers. The Flathead tribe used the dried, powdered plants to preserve meats and berries. It is said to make a nice pineapple flavored tea.

Last year I showed the flower of a plant I had never seen before and couldn’t identify in the hope that someone would recognize it. Apparently nobody could recognize it by the flower so this year I’m showing the entire plant. The flowers are tiny; about the same size as those on red sandspurry, and blossom on the ends of wiry stems. Its leaves are also small and sword shaped and very hard to see in this photo. This entire plant shown would fit in a tea cup with room to spare.

Here is the pretty little flower of the unknown plant. I find them growing in the sand on roadsides in full sun, much like a sandspurry would. They don’t seem to mind dry soil but they must also like water because I’m seeing more of them in this rainy summer than I ever have. I’ve searched all my wildflower books and online off and on for over a year with no luck, so if you know its name I’d love to hear from you.

NOTE: With a little help from some friends Al Stoops has identified this plant as low baby’s breath (Gypsophila muralis.) It is an annual plant native to Europe and available commercially, sold as cushion baby’s breath. Thanks Al!
