Posts Tagged ‘Box Elder Buds’

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

Thanks for stopping in.

1. Sap Buckets

If you could only take one photo to tell the rest of the world that it was spring in New England, it would have to be of sap buckets hung on a maple tree. In spite of 25 of 31 days in March being colder than  average the sap is flowing, but one syrup producer says that he has collected only about a third of the sap that he had last year at this time.

2. Red Maple Buds

The purple bud scales of red maple (Acer rubrum) have pulled back to reveal the tomato red buds within. Once the buds break and the tree starts to flower the sap becomes bitter, and maple syrup season ends. That usually happens in mid to late April. If you don’t want to look at a tree’s buds another sign is when the nights become warm enough to get the spring peepers peeping.

3. Budded Daffodils

Some of the daffodils are budded, but they have been for a while. They seem to be waiting for the weather to make up its mind before they’ll open. Either that or I’m just getting impatient.

4. Witch Hazel Petals

Hesitantly, like a child sticking a toe in the water to feel its temperature before wading in, the spring witch hazels have started to unfurl their strap like petals.  Last year they unfurled quite early and the cold turned them brown, so I think we’re seeing a “once bitten, twice shy” scenario here this year.  Though we do have a native vernal witch hazel (Hamamelis vernalis), it doesn’t grow naturally this far north, and since this one is in a park I’m betting it’s one of the cultivated witch hazels. The other American witch hazel (Hamamelis virginiana) that is native to New England blooms in the fall and grows in the same park.

 5. Dwarf Raspberry Leaves

I did find some green leaves in the woods, but they were on the evergreen dwarf raspberry (Rubus pubescens.) This plant likes wet places and trails along the ground like a dewberry, but it has smooth stems and dewberries have prickly stems. Its fruit looks and tastes much like a raspberry, but good luck getting any of it. Birds and animals eat the berries as fast as they ripen.

6. Ledge Ice

There is still plenty of snow and ice to be seen as this photo shows. Still, this is a sign of spring because this ice is rotten and parts of it were falling as I was taking this photo. The opaque milky grayish-white color of this ice was a sure sign that it was rotten, so I didn’t get too close. When ice rots the bonds between the ice crystals weaken and water, air or dirt can get in between them and cause the ice to become honeycombed and lose its strength. It looks to be full of small bubbles and has a weak, dull sound when it is tapped on. It’s a good thing to stay away from when it gets to be taller than you are.

7. Box Elder Buds

A couple of posts ago I talked about pruinose lichens but they aren’t the only things that can be pruinose, as these box elder buds (Acer negundo) show. In case you’ve forgotten, pruinose means a surface that is covered in white, powdery, waxy granules that seem to be able to reflect light in ways that often make the surface they are on appear blue. Certain grapes, plums, and blueberries are pruinose fruits that we are all familiar with.

8. Common Split Gill Mushrooms

Split gill mushrooms (Schizophyllum commune) had their winter coats on, as usual. These are “winter” mushrooms that are usually about the size of a dime but can occasionally get bigger than that. They grow on every continent except Antarctica and because of that are said to be the most studied mushroom on earth. Their wooly coats make them very easy to identify.

9. Common Split Gill Mushroom

The “gills” on the split gill fungus are actually folds on its under surface that split lengthwise when it dries out. The splits close over the fertile surfaces as the mushroom shrivels in dry weather. When rehydrated by rain the splits reopen, the spore-producing surfaces are exposed to the air, and spores are released. These little mushrooms are very tough and leathery.

 10. Golden Foxtail Moss aka Brachythecium salebrosum

I think this golden foxtail moss (Brachythecium salebrosum) has to take the prize for the longest moss that I’ve seen; its branches must have been at least 2 inches long. It’s unusual because it likes dry places, and I found it growing on stone in a shaded spot under an overhang, where it must have seen very little direct rainfall. This moss has insect repellant qualities and was once used to stuff pillows and mattresses. Today it is a favorite in moss gardens and in India they use it to wrap fruit in.

11. Moss With Unknown Growth

White cushion moss (Leucobryum glaucum) gets its common name from the way it turns a whitish color when it dries out. When wet though, it can be dark green as this photo shows. What this photo also shows are some fuzzy white growths on the moss that I’ve never seen before.

12. Moss With Unknown Growth

I don’t know if the fuzzy white things are mold that has grown due to the moss being covered by ice, or what they are. I’ve seen two different photos online of cushion moss with the same growths, but neither site explained what they were. If you’ve ever seen them and know what they are I’d like to hear from you.

 13. Whiskered Shadow Lichen aka Phaeophyscia hispidula

This is my first photo of a whiskered shadow lichen (Phaeophyscia adiastola.) It’s one of those easily ignored lichens that you think you see all the time but in reality when you look closely, you realize that you’ve never seen anything quite like it. This lichen grows on bark, stone or soil and gets its common name from its abundant root-like rhizines, which show here as a kind of black outline. I found it growing on a piece of ledge that dripping water splashed on, so it was very wet.

14. Whiskered Shadow Lichen closeup

This isn’t a very good photo but at least you can see the “whiskers” that give the whiskered shadow lichen its common name.  These rhizines help foliose lichens anchor themselves onto whatever they’re growing on, much like the roots of a vascular plant would.

 15. Inner Tree Bark

This is nothing but an old piece of bark that I found lying on the snow, but it was quite large and the photo shows what I saw when I turned it over. This is the side that would have been next to the wood of the tree, unseen. I thought the colors and patterns were amazing. If fungi would have caused this is a question that I can’t answer.

April is a promise that May is bound to keep. ~Hal Borland
