A Few More Signs of Spring

Last weekend I went looking for signs of spring again and this thin ice sign was one of those I found. Thin ice at this time of year is a good sign if you happen to be a spring lover. The town puts them up in fall as the ice starts to form, then takes them down for the winter and puts them up again in spring when it starts to thaw. It’s good to pay attention to them; there have been photos in the local newspaper of plow trucks sitting in water up to their windows after going through this ice.

The ice was pulling back from shore so you wouldn’t catch me skating on it.

The willows are really coming along now. The soft gray catkins could be seen everywhere on this day.

I’m not seeing any yellow in them yet though, so it will be maybe a week or two before they flower.

I did see lots of pinecone galls on the willows. This gall appears at the branch tips and is caused by a midge (Rhabdophaga strobiloides) laying eggs on them. Once the eggs hatch the larva burrow into the branch tip and the plant reacts by forming a gall around them. They aren’t very big but are very noticeable at this time of year. Galls and the insects that cause them, and the reactions of the various plants they appear on is a fascinating subject but they always lead me to two questions: how and why?

Hazelnut catkins are continuing their spring color change over to gold from green. I usually see the tiny scarlet female flowers in April but I have a feeling they might come a little earlier this year.  

This might look like an old pile of leaves but it is actually a hellebore plant. Hellebores bloom quite early so I usually start watching them at about this time of year. Another name for them is Lenten rose, because they will often bloom during Lent.

Crocuses have appeared alongside what I think are reticulated iris, and they are growing fast. A week ago there was no sign of them. The warm weather and rain this week should give them and everything else a good boost.

Daffodils are on hold, just waiting for the silent signal. The bed they’re in needs some serious weeding.

Since these are not my gardens, I can’t be positive but I do know that hyacinths grow near the front of this bed. Unfortunately an animal had dug down and eaten many of them. I’ve seen chipmunks and squirrels but no skunks, racoons or possums yet, so I’m not sure what could have done it.

There was quite a mound of good-looking soil that had been dug up. There’s nothing like the smell of newly thawed soil in spring.

This bulb had been rejected so it might be a daffodil. Daffodils are poisonous and somehow, animals know it.

I was surprised to see tulips up. No buds yet though, just leaves.

I keep checking the trails, hoping the ice will have melted. It is melting but not very quickly. Hopefully after the warmth and rain this week they will finally be clear of ice. I’ll never forget this winter. It has been one of the iciest I can remember. Even trail reports on the radio are saying that you should bring spikes.

I went to see a Cornelian cherry to see if it had woken up yet and I was very happy to see some yellow inside the bud scales of that pea size bud on the left. It won’t be long before its small but pretty yellow flowers unfold. I’ve seen them as early as late March. Last Sunday it was 65 degrees, so we might see them in March again this year.

Magnolia buds are covered by a single hairy bud scale called a cap and when the bud inside the cap starts to swell in spring the bud scale will often split and fall off, but as can be seen here by the bare space under the bud scale, the bud seems to be pushing the cap up and off. I’ve never noticed this before, but maybe it happens regularly, I don’t know. In any event it signals that magnolia buds are beginning to stir.

I took a look at the big horse chestnut buds. They’re easy to see but not so easy to get a photo of because they’re up over my head. Beautiful flowers will appear out of these buds in mid to late May.

Since most people have probably never seen a red horse chestnut blossom (Aesculus × carnea,) here is a not very technically good photo of what they look like. The tree is a cross between the red buckeye (Aesculus pavia) and the horse chestnut (Aesculus hippocastanum.) I’ve read that bees and hummingbirds love the beautiful red and yellow blossoms.

After visiting the horse chestnut, I thought I’d wander over to the big old red maple. There still wasn’t a lot going on in its buds but they bloom in March so it won’t be long. Maybe it will be a sudden awakening. Speaking of sudden awakenings, I heard the first red wing blackbird today. If that isn’t a sign of spring then I don’t know what is. Soon the spring peepers will add their trills to the chorus.

Johnny jump ups were still blooming, even though they had been covered by snow for a week. I might apply for a part time job at the local college. That’s where some of the beds you see in these photos are located and they’re so full of weeds I’m almost embarrassed to show them. Maybe they would welcome a part time weeder. This bed is full of spring bulbs so it should be weeded before they come up.

I went to see the skunk cabbages, hoping that the spathes had opened so I could get a shot of the spadix with its strange little flowers, but they weren’t quite ready. You can just see a crack opening on the lower rights side of the bulbous part of this spathe but it’s nowhere near open enough to get my lens in. Maybe next week. I’d better bring something to kneel on though because the swampy ground had thawed and water filled every footstep.

The spring blooming witch hazels were in full bloom and I wanted you to see this one because of the translucence of the petals. Having to get so close to them to get a photo meant that I was awash in their wonderful fragrance. I find it impossible to describe but other have likened it to fresh laundry just taken down from the clothes line.

This witch hazel couldn’t have bloomed any more than it was. It had nice color too.

I chose this photo so you could see the different stages of a witch hazel bloom. On the upper right the petals are just emerging, and below that they are about half way unfurled. Finally in the center the flowers have fully opened. I’ve discovered this year that this can happen very fast. There are 4 or 5 different varieties in this group and as I wandered among them taking photos by the time I got back to where I had started many more flowers had opened on that first shrub I looked at. This was in the space of maybe 15-25 minutes.

In those vernal seasons of the year, when the air is calm and pleasant, it were an injury and sullenness against Nature not to go out and see her riches, and partake in her rejoicing with heaven and earth.  ~John Milton

A Few More Signs of Spring

It certainly appears that spring is upon us but those of us who have been around for a few decades are always wary of a false spring. A false spring, for those who don’t know, is a period of unusual warmth in late winter or early spring that can last long enough to bring plants and animals out of dormancy. When the normal cold temperatures return, sometimes weeks later, the plants and animals that have woken early are taken by surprise and can suffer. I haven’t seen any alarming signs of plants waking early but the bears and skunks are awake, and they’re hungry. The Fish and Game Department has been telling us to stay out of the way of the bears, which is surely good advice even if it is common sense. One of the signs of spring that I’ve always enjoyed is the way willows turn golden, as the one in the above photo has. There is a species of willow from Europe and Asia called golden willow (Salix alba vitellina) but I have no way of knowing if this tree is that one.

Another tree I always love seeing in spring is the red maple, with all of its globular red buds standing out against a blue sky. Each season seems to have its own shade of blue for the sky. A spring sky isn’t quite as crisp as a winter sky but it is still beautiful. The level of humidity in the air can make a difference in the blue of a sky because water vapor and water droplets reflect more of the blue light back into space. This means we see less blue than we do when water vapor is at a lower level. The scientific term for this phenomenon is “Mie scattering.” The sun’s angle can also make a difference in how much of the blue we see.

I found these red maple buds near the Ashuelot River in Keene and was surprised to see so much red on them. The purple bud scales slowly open to reveal more and more red and soon after this stage the actual flowers will begin to show. The flowers open at different times even on the same tree, so the likelihood of them all being wiped out by a sudden cold snap is slim. Early settlers used red maple bark to make ink, and also brown and black dyes. Native Americans used the bark medicinally to treat hives and muscle aches. Tea made from the inner bark was used to treat coughs. 

We have sugar maples where I work and someone broke a twig on one of them. The other day I noticed it was dripping sap, so syrup season is under way.

I didn’t see any dandelions blooming but that’s only because I was late getting there. There were three plants in one small area with seed heads all over them. I’ve seen them bloom in January and March but never in February, so I would have liked to have seen them.

The skunk cabbages (Symplocarpus foetidus) are happy in their swamp. Bears that come out of hibernation early will sometimes eat skunk cabbages but not much else bothers them. There is little  for bears to at this time of year but a helpful reader wrote in and said that they also dig up and eat the roots of cattails. When I was taking these photos a small flock of ducks burst from the cattails not five feet from me. You won’t need a defibrillator when that happens I’ll tell you, but what struck me most about it was the sound of snarling just before the flock hit the sky. I wonder if they were being stalked by a bobcat when I came along and ruined its hunt. If so I never saw it but it was an angry snarl that didn’t sound like any duck I’ve ever heard.  

Through a process called thermogenesis skunk cabbages are able to generate temperatures far higher than the surrounding air. You can often see evidence of skunk cabbage having melted their way through several inches of solid ice. I saw plenty of the splotchy spathes but I didn’t see any that had opened to reveal the flower studded spadix within.

I went to one of my favorite places to find pussy willows and found that they had all been cut down. Luckily I know of more than one place to see them but I had to wonder why anyone would have cut them. Unless you get the roots they’ll grow right back, bushier than ever. I’ve seen willow shoots even grow from cut willow logs, so strong is their life force.

Another fuzzy bud is the magnolia, but I’m scratching my head over what is going on here. The bud scales of the magnolia are fuzzy and gray and they open and fall off when the flowers open, but here it looks like the bud scales have opened to reveal more bud scales. Could the open scales still be there from last spring? Hard to believe but possible, I suppose.

I saw some alder catkins that were still covered with the natural glue that protects the flower buds. Each brown convex bit seen here is a bud scale which will open to let the male flowers bloom. Between the bud scales is a grayish, waterproof “glue” that keeps water out. If water got in and froze, all the tiny flower buds inside would be killed. Many plants use this method to protect their buds.

You can see the same “glue” on the buds of American Elms. Also sugar maples, poplars, lilacs, and some oaks protect the buds in this way. I assume that the warming temperatures melt this waxy glue in spring so the bud scales can open.

In places with a southern exposure the snow pulls back away from the forest, and this happens because the overhanging branches have reduced the amount of snow that made it to the ground along the edges of the woods.

Though the grass in the previous shot was brown I did see some green.

I also saw some mud. They might not seem like much but green grass and mud really get the blood pumping in people who go through the kind of winters we can have here. When I was growing up it wasn’t uncommon to have shoulder deep paths through the snow drifts and 30 degree below zero F. (-34.4 C)  temperatures. In those days seeing mud in spring could make you dance for joy. But then mud season came so we put on our boots. Mud season turns our dirt roads into car swallowing quagmires each spring for a month or so.

One of the theories of why evergreen plant leaves turn purple in winter is because they don’t photosynthesize, they don’t need to produce chlorophyll. Another says the leaves dry slightly because the plant doesn’t take up as much water through its roots in winter. It is called “winter bronzing” and whatever the cause it can be beautiful, as these swamp dewberry (Rubus hispidus) leaves show. Before long they’ll go back to green and grow on without having been harmed at all.

The hairy, two part valvate bud scales of the Cornellian cherry are always open just enough to allow a peek inside. The gap between the bud scales will become more yellow as the season progresses and finally clusters of tiny star like yellow flowers will burst from the bud. These buds are small, no bigger than a pea. I’m not sue what the hairs or fibers on the right side are all about. I’ve never seen them on these buds before. Cornelian cherry (Cornus mas) is an introduced ornamental flowering shrub related to dogwoods. It blooms in early spring  and has a long history with mankind; its sour red fruit has been eaten for over 7000 years, and the Persians and ancient Romans knew it well.

Daffodil leaves that have been weakened by the cold will often be yellowed and translucent but these looked good and heathy and green. Even if the plant loses its leaves to cold it can still bloom but since it has to photosynthesize to produce enough energy to bloom it probably won’t do so the following year. It might take it a year or two to recover.

I didn’t expect to see tulip leaves but there were several up in this sunny bed.

I know I just showed some lilac buds in my last post but these looked like they had been sculpted by an artist. I thought they were very beautiful and much more interesting than the plain green buds I usually see. You can see all of life, all of creation right here in these buds. Maybe that’s why I’ve spent all of my life watching lilac buds in spring.

I’ll close this post with a look at another venal witch hazel blossom, because it is a very rare thing to see flowers of any kind blooming here in February. They’re tiny little blossoms but their beauty is huge.
