The spring growth on a white pine (Pinus strobus) begins when the terminal bud at the end of a branch forms what is called a “candle.” The cluster of candles in the photo above are new shoots that will bear the tree’s leaves (needles.) White pine needles grow in bundles of 5 and last for 2 years before turning first yellow and then brown before finally falling off. White pine needles contain five times the amount of vitamin C of lemons and were used by Native Americans to make tea. The knowledge they shared saved many early settlers who were dying of scurvy.
Both the cinnamon (Osmundastrum cinnamomeum) and interrupted fern (Osmunda claytoniana) are up and growing quickly. Both have wooly fiddleheads that make them hard to tell apart when young, but there are clues.
If you look closely you might see each fiddlehead is covered by tiny spherical bumps.
These tiny spheres are the fern’s spore bearing sporangia, and of the two ferns only interrupted fern has sporangia on its fronds. Cinnamon ferns grow separate fertile fronds that bear its sporangia and they appear a little later on, so I’d say that these fiddleheads belong to the interrupted fern. In any case neither fern has edible fiddleheads. In fact some ferns have fiddleheads that are carcinogenic, so if you want to eat fiddleheads in spring it pays to learn all you can about them.
As the sun gets brighter and the days grow longer light sensitive tree buds can tell when there is enough daylight for the leaves to begin photosynthesizing, so the buds begin to break. Bud break is defined as “when the green tip of a leaf can be seen emerging from the bud” and this can be a very beautiful thing. American beech (Fagus grandifolia) bud break begins when the normally straight buds start to curl, as in the above photo. The curling is caused by the cells on the sunny side of the bud growing faster than those on the shaded side. This creates a tension that curls the bud and eventually causes the bud scales to pull apart so the leaves can emerge. At the bud’s location on the tree branch an entire year’s new leaves and stems will often grow from a single bud.
When I see beech buds begin to curl I watch them closely, because I know that any time now the new leaves will appear and I wouldn’t want a spring to pass without seeing them. They are silvery and downy and very beautiful at this stage and I’ve lost myself in their beauty many, many times.
The process of bud break in beech trees moves from start to finish very quickly so you have to watch closely but luckily each tree’s buds will break at different times, so you still have a chance to witness it if you live in the Keene area. Due to the cool rainy weather (I think) some buds are still just starting to curl.
The only example of plantain leaved sedge (Carex plantaginea) that I know of grows in an old stone wall and is blooming now. The prominent midrib, two lateral veins, maroon bases, and puckered look of the leaves are all used as identifying features for plantain leaved sedge. The leaves can be up to a foot long and an inch wide and I can’t think of another sedge that has leaves that look quite like these.
The flowers stalks (culms) of plantain leaved sedge are about 4 inches tall and have wispy, white female (pistillate) flowers below the terminal male (staminate) flowers. Sedge flowers are actually called spikelets and the stems that bear them are triangular, hence the old saying “sedges have edges.” I can’t speak for the rarity of this plant but this is the only one I’ve ever seen and it isn’t listed in the book Grasses: An Identification Guide, by Lauren Brown. I’ve read that it likes cool shady places where the humidity is relatively high. There is a stream just a few feet from where this one grows.
New spring leaves on many hardwood trees show some amount of red but sunlight and warmth quickly turn them green so they can photosynthesize. When we have a cool, cloudy spring like we’re having this year though, the red stage can last considerably longer. It also seems to depend on the tree; I’ve seen new spring leaves of both red and green on maples.
Oak trees are among our last to leaf out but with the cloudy cool weather holding some trees back it seems to be happening all at once this year. New spring oak leaves are often red but not these examples, even though they still wear their soft downy coatings.
Japanese knotweed (Fallopia japonica) can be very beautiful as it spreads its new leaves to catch the sun. Unfortunately it’s also very invasive and almost impossible to control. I’ve seen Japanese knotweed shoots killed to the ground by cold in the past, and within 3 weeks they had come right back and grew on as if it had never happened. The plants grow quickly into large, 4-5 foot tall shrub like masses that shade out natives. I’ve heard that the new shoots taste much like rhubarb, so maybe if we all developed a taste for them we could finally eradicate them, at least from our roadsides.
The shoots of the common or field horsetail (Equisetum arvense) seemed to appear overnight in a large colony that thankfully wasn’t near anyone’s garden. If you’ve ever tried to rid a garden of them, you know what I mean.
The fertile spore bearing stem of a common or field horsetail ends in a cone shaped structure called a strobilus. Since it doesn’t photosynthesize at this point in its development the plant has no need for chlorophyll, so most of it is a pale, whitish color. When it’s ready to release its spores the cone opens to reveal tiny, mushroom shaped sporangiophores. The whitish “ruffles” at the base of each brown sporangiophore are the spore producing sporangia. When the horsetail looks like the one in the photo it has released its spores and will soon die and be replaced by the gritty green infertile stems that most of us are probably familiar with. Horsetails were used as medicine by the ancient Romans and Greeks to treat a variety of ailments.
More people are probably familiar with the infertile stems of horsetail, shown here. They grow from the same roots as the fertile spore bearing shoots in the previous two photos and they do all the photosynthesizing. Horsetails spread quickly and can be very aggressive. If they ever appear in your garden you should remove them as soon as possible, because large colonies are nearly impossible to eradicate.
I was admiring these beautiful spruce tree cones (flowers) when it hit me: Wait a minute, I thought; spruce cones always hang down and fir cones always stand up! Well, yes and no. After quite a lot of research I found that young cones of some spruce and pine trees stand up until they are pollinated. This is because they are pollinated by wind borne pollen, and it’s easier for the pollen to settle onto the open cones while they’re in an upright position like those in the photo. Once pollinated they close up, turn green and grow bigger and heavier until they tip over, where they hang until the seeds mature. Once the seeds mature the cones open and the seeds (or the cones) fall to the ground. So is it true that fir cones always stand up and spruce cones always hang down? As is often the case in nature, if you remove the word always the answer is yes.
I thought that this unfurling shoot of Solomon’s seal (Polygonatum biflorum) was very beautiful. This is a fast growing plant once it gets started and I’ve seen others with flower buds already. Native Americans sprinkled the dried powdered roots of this plant on hot stones and inhaled the smoke to alleviate headaches. All parts of the plant except the roots and young shoots are poisonous, but that’s assuming you know how to prepare the roots and young shoots correctly. Sometimes the preparation method is what makes a plant usable.
I love the movement in the young spring shoots of whitebane berry (Actaea pachypoda) and I look for them every spring. They’re such a beautiful and interesting little things, with new leaves that always remind me of prehistoric hands or wings. If I was still drawing they would be one of my first subjects.
Native Americans used a root tea for various problems including pain, colds and coughs but the entire white baneberry plant is extremely poisonous and its berries especially so, so no part of it should ever be eaten. The bitter berries are white with a single black dot that gives them the common name doll’s eyes. In summer the berries follow a raceme of white flowers that is taller than it is wide, and which will grow from the tiny buds seen in this photo.
Each summer for the past two years we saw nothing but wall to wall sunshine, day after day for month after month. Clouds were rare and I complained about how boring it was to see a never ending flat blue sky. This year nature seems to have decided that it was time I learned another lesson; for the first half of May sunny days have been rare. I took this reflection photo on one of those rare days when the sun was shining. It was also very still that day. Days without wind have also been few but things seem to be turning around now. We’ve had four sunny days in a row this week.
It is very important to go out alone, to sit under a tree—not with a book, not with a companion, but by yourself—and observe the falling of a leaf, hear the lapping of the water, the fishermen’s song, watch the flight of a bird, and of your own thoughts as they chase each other across the space of your mind. If you are able to be alone and watch these things, then you will discover extraordinary riches which no government can tax, no human agency can corrupt, and which can never be destroyed. ~ Jiddu Krishnamurti

A Little History and a Little Botany = A Perfect Day

Last Sunday I decided to follow a rail trail in Swanzey that I knew had a trestle on it. History and botany are two of my favorite things and I knew I’d find a lot of both here. It was a beautiful warm, sunny day and hiking just about anywhere would have been pleasant.
Sometimes the sap of white pines will turn blue in very cold weather but it was warm on this day and the sap was still blue. I wonder if it stays blue once it changes.
I’ve never heard of bunchberry (Cornus canadensis) being evergreen but there were several plants along the trail, all wearing their winter purple / bronze color. If this plant looks familiar it’s probably because it is the smallest of our native dogwoods and the 4 leaves look like miniature versions of dogwood tree leaves. Bunchberry gets its common name from its bunches of bright red berries. It is also called creeping dogwood and bunchberry dogwood. Native Americans used the berries as food and made a tea from the ground root to treat colic in infants. The Cree tribe called the berry “kawiskowimin,” meaning “itchy chin berry” because rubbing the berries against your skin can cause a reaction that will make you itch.
Something unusual I saw this day was a Canada yew (Taxus canadensis.) It is native from Newfoundland west to Manitoba, south to Virginia, Tennessee, Illinois, and Iowa, but in this region I rarely see it. Though all parts of the yew plant are poisonous several Native American tribes made tea from the needles to ease everything from numbness to scurvy. A man in England died not too long ago from eating yew, so I wouldn’t advise trying to make tea from it. Natives knew how to treat poisonous plants in ways that made them beneficial to humans, but much of that knowledge has been lost.
A yew branch looks very flat and once you get to know what they look like you’ll never mistake it for any other evergreen.
Snowmobile clubs have built wooden guardrails along the sides of all of the train trestles in the area to make sure that nobody goes over the side and into the river. That wouldn’t be good, especially if there was ice on the river. Snowmobile clubs work very hard to maintain these trails and all of us who use them owe them a great debt of gratitude, because without their hard work the trails would most likely be overgrown and impassable. I hope you’ll consider making a small donation to your local club as a thank you.
Years ago before air brakes came along, brakemen had to climb to the top of moving boxcars to manually set each car’s brakes. The job of brakeman was considered one of the most dangerous in the railroad industry because many died from being knocked from the train when it entered a trestle or tunnel. This led to the invention seen in the above photo, called a “tell-tale.” Soft wires about the diameter of a pencil hung from a cross brace, so when the brakeman on top of the train was hit by the wires he knew that he had only seconds to duck down to avoid running into the top of a tunnel, trestle, or other obstruction. Getting hit by the wires at even 10 miles per hour must have hurt some, but I’m sure it was better than the alternative. Tell tales are rarely seen these days; the above photo shows the only example I know of.
The Ashuelot River was full in places.
And over full in others. This happens regularly throughout this area and the trees survive it just fine. Many are silver (Acer saccharinum) and red maples (Acer rubrum.) Another name for them is swamp maple because they often grow in the lowlands along rivers that flood regularly.
The large crimson bud clusters make the maples easy to spot at this time of year but I couldn’t tell if these examples were flowering or not. Many are, now that we’ve had some warmth.
There isn’t a lot of ledge in this section of trail but there is some and it shows the marks of a steam drill. The railroad workers cut through the solid rock by drilling deep holes into the stone using steam powered drills and then poring black powder into them. Packing these holes with black powder and lighting a fuse was a very dangerous business and many were killed doing it, but dynamite wasn’t invented until 1866 so it was either black powder or brute force. Trains first rolled through here in the mid-1850s.
Maple dust lichens (Lecanora thysanophora) are beautiful and are definitely worth looking for. I’ve found them growing on maple, oak, beech, and poplars. They are usually quite a different green but the camera didn’t seem to be seeing green very well this day.
You can tell that it’s a maple dust lichen by the tiny fringe around its outer edge.
The trail goes on for many miles and it is wide, flat, and sometimes busy as it was on this day. I saw several people while I was here and I was happy to see them out enjoying nature. I hope they saw as many interesting things as I did.
There was snow for anyone who might want it. I didn’t.
American beech (Fagus grandifolia) bud break begins when the normally straight buds start to curl, as in the above photo. The curling is caused by the cells on the sunny side of the bud growing faster than those on the shaded side. This creates a tension that curls the bud and eventually causes the bud scales to pull apart so the leaves can emerge. At the bud’s location on the tree branch an entire year’s new leaves and stems will often grow from a single bud. Beech bud break doesn’t usually start until mid-May, so I think the example in this photo is a fluke caused by early warmth. Others I saw had not curled yet.
Partridgeberry (Mitchella repens) is one of the lowest growing evergreen plants on the forest floor, hardly growing more than 3 or 4 inches high. Plants have a vining habit but do not climb. Instead they form dense mats by spreading their trailing stems out to about a foot from the crown. Roots will often form at leaf nodes along the stems and start new plants. The 4 petaled, pinkish, fringed, fragrant, half inch long flowers appear in June and July. The berries remain on the plant for long periods unless eaten, and can often still be found the following spring.
Partridgeberry flowers are fused at the base. Once pollinated, the ovaries of these flowers will join and form one berry with 8 seeds. Partridgeberry plants can always be easily identified by the two indentations on the berries that show where the flowers were. Other names for this plant include twinberry and two-eyed berry. Native Americans ate the berries and made them into a jelly, which was eaten in case of fevers. Partridgeberry is still used in folk medicine today to treat muscle spasms and as a nerve tonic.
Apple moss (Bartramia pomiformis) grows along the sides of the trail and its thousands of tiny spore capsules were shining in the sun. Reproduction begins in the late fall for this moss and immature spore capsules (sporophytes) appear by late winter. In the spring the straight, toothpick like sporophytes swell at their tips and form tiny globes that always look like pearls to me, but someone thought they looked like apples and the name stuck. Sometimes the capsules do turn red as they age, so I suppose the name makes sense.
Most of these spore capsules were not quite spherical and that means that they were still immature. When they become spherical the spores will begin to ripen and prepare for the wind to disperse them.
Human history and natural history are visible from rail trails. The old railroad routes through a town can show a lot about how the town developed, what it was like long ago. When you go through a town by bicycle on an old railroad route, the place looks very different than from the customary perspective of the car and the highway. ~Peter Harnick
