Signs of Spring and Other Things

Last Saturday the weather wasn’t cooperating at all. As the above radar image shows there was a thin ribbon of rain from the Midwest to the northeast. In my corner of New Hampshire it was in the mid-30s and we had snow mixed with rain, which translates into a sloppy mess. With the hill climbing trails still covered in snow and ice March continues to be a challenge.

This is what the view out my back door looked like while it snowed.

In spite of a near blinding snow squall this willow’s golden branches lit up this space. Golden willows are one of the earliest signs of spring in this area.

I’m guessing that I won’t be seeing any yellow flowers on the pussy willows (Salix) real soon. Once the snow stopped they had ice on them on this day.

A sedum decided to throw caution to the wind and come up anyway, even if it was snowing. The shoots looked like tiny cabbages.

Buds of American elm (Ulmus americana) are just starting to open. Their flowers are unusual and beautiful and I hope I don’t miss them this year. I know of only two trees with branches low enough to reach.

Last year this magnolia blossomed too early and lost nearly every flower to frost because of it, but this year there is still a single furry bud scale on every bud. They looked a little wet and bedraggled but they’re still protecting the flower buds inside. Soon they’ll fall off and the tree will start to blossom, cold weather or not.

It looked like the bud scales on these box elder buds (Acer negundo) were just starting to open. The buds and young twigs of box elders are often a beautiful blue or purple color due to their being pruinose. Pruinose means a surface is covered in white, powdery, waxy granules that reflect light in ways that often make the surface they are on appear blue. Certain grapes, plums, and blueberries are pruinose fruits. Certain lichens like the beautiful smoky eye boulder lichen have fruiting bodies (Apothecia) that are often pruinose. Box elder is in the maple family and several Native American tribes made sugar from this tree’s sap.

Lichens are at their best in wet weather so I decided to look at a few I hadn’t seen in a while. I can’t speak for the rarity of hammered shield lichen (Parmelia sulcata) but I do know that I rarely see it. This lichen gets its common name from the way it looks like its lobes were hammered out of a sheet of steel. This one grows on a tree in a local shopping mall. It’s the only example that I could confidently lead  someone to if they asked to see one.

On the same tree, just a few inches away, grows a star rosette lichen (Physcia stellaris) that produces spores quite regularly. The dark brown apothecia with white rims are fairly easy to see without magnification but there was something else here that I had never seen.

I’ve seen many lichens with apothecia that are cup shaped as this one has but some of these cups were full of water, and that’s something I’ve never seen. I don’t know how or even if this benefits the lichen but I do know that most of them like a lot of water. Star rosette lichen gets its common name from the way its lobes radiate outward like a star.

If you don’t mind getting down on your stomach in the kind of swampy ground that they like to grow in you can sometimes get a peek inside the spathe of a skunk cabbage (Symplocarpus foetidus) to see its flowers. A spathe is just a modified leaf or bract which kind of wraps around itself and protects the flower bud. As the plant matures a gap opens in the spathe to let in the insects which will pollinate the flowers. This one was open far more than they usually are and I wondered if someone had been there before me, taking a peek inside.

Inside the skunk cabbage’s spathe is the spadix, which is a one inch round, often pink or yellow stalked flower head from which the small flowers emerge. The flowers don’t have petals but do have four yellowish sepals. The male stamens grow up through the sepals and release their pollen before the female style and pistil grow out of the flower’s center to catch any pollen that visiting insects might carry from other plants. The spadix carries most of the skunk like odor at this stage of the plant’s life, and it is thought that it uses the odor to attract flies and other early spring insects. This example had released a large amount of pollen and it was stuck to the insides of the spathe. In 1749 in what was once the township of Raccoon, New Jersey they called the plant bear’s leaf because bears ate it when they came out of hibernation. Since skunk cabbage was and is the only thing green so early in the spring so if the bears woke up too early they had to eat it or go hungry.

Some of the skunk cabbages came up too early and paid for their mistake by being frozen. Now their spathes are shriveled and black. This one had a new green leaf shooting up beside it but its spathe didn’t look good. The leaf will keep the plant alive but it will have to wait until next year to blossom again. There is a time when they’re young that the leaves do look somewhat cabbage like but they grow quickly and lose any resemblance once they age.

I doubt it would help pollinate a skunk cabbage but I did see what I think is a wasp recently. It seemed sluggish; most likely because of the cold. It did finally rear up on its hind legs when I got the camera too close, but I don’t think it was in any position to sting just yet. It seemed like it could barely stand. After a couple of quick shots I left it alone to contemplate the weather.

Reticulated irises (Iris reticulata) are our earliest iris I think, and usually bloom at about the same time as the crocus does, though this year I saw a crocus blossom two weeks ago. This beautiful and tough little plant comes from Turkey, the Caucasus, Northern Iraq and Iran.

This one looked more like an iris, even with the ice on it making its petals curl. Reticulated iris are a much tougher plant than I ever realized and I appreciate them and the other early bloomers showing me that spring is indeed here, even though it still feels like winter.

The first day of spring is one thing, and the first spring day is another. The difference between them is sometimes as great as a month. ~Henry Van Dyke
