Treefollowing: Wordless Wednesday (nearly)

Flash the maple is thick with dried samaras.
Spike the hawthorn still sports a bit of red and green.

~🍂~


Though the beech is golden
I cannot stand beside it
mute, but must say

"It is golden," while the leaves
stir and fall with a sound
that is not a name.

It is in the silence
that my hope is, and my aim.
...
The Silence by Wendell Berry

 

This is my brief contribution to November's gathering of Treefollowers. Consider joining us—as you can see, it doesn't have to be a lot of work. Photos would have been enough, but like Berry, I "must say".

Green and Red; Stipules and Suckers

In the foreground is skinny Spike, the hawthorn. Behind is Flash, the maple (red canopy).
Since my last report, there has been only a little change in the trees I'm following. Flash's canopy has become even more red, though we've had nothing close to a frost. Spike is still a skinny odd-looking "tree".

Flash has only a few green leaves. The foliage is pretty ragged all in all.
When backlit, the aging samaras (keys) are still beautiful.
For Spike, it is the young leaves that are reddish. The rest are still green.

Now, for botany nerds ...

This month, Spike brought up several botanical terms which I "know" but not really; terms I've heard and even used for decades, but when pressed to explain, can't. At least not confidently. So I asked Google, the expert on everything (we hope).

Stipule: "an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf ..."

If you like order, stipule classification is for you! There are types based on many different characteristics, such as duration, shape, size, position, modification, and more. I preferred the summary of function: "Stipules have various functions. Some stipules are not well understood or may be vestigial." This is the way I feel about many things these days.

This hawthorn has foliaceous stipules, i.e., similar to leaves. Being green, perhaps they contribute to photosynthesis—the business of making energy for the tree. I would guess Spike could use the help, having recently recovered from near death. And maybe this is why stipules are more prominent on the suckers (the next topic).

Enlarge to see stipules at base of leaves.
Suckers seem to be universally despised, according to Google. For example, "young stems sprouting from the base or from a spot on the trunk ... are called suckers, because they zap water and nutrients from the main tree. As suckers are unhealthy for trees and they are unsightly, it’s important to know how to eliminate them ..." More here.

The Wikipedia article about Plant Development is more open-minded (see Adventitious structures; Buds and shoots). "Adventitious buds [buds that develop in unusual locations on the plant] are often formed after the stem is wounded or pruned. The adventitious buds help to replace lost branches." I agree! Adventitious shoots are very helpful in this situation.

Tree-following: Red and Green


Both trees I'm following this year are red and green, but in different ways. Last month, Flash the maple was covered in green leaves and red samaras. The samaras are still red but looking duller. And the leaves are starting to turn red. It hasn't been cold, not even close. Could this be due to heat and smoke? Or maybe just normal life for Flash.

Spike the hawthorn still has rich green leaves, while the young emerging leaves are reddish. No flowers or fruit this year, but that's fine. Having nearly died (or so it looked!), Spike is to be commended for the healthy shoots and foliage.

Christmas in July and a Surprise!

Hotwings Maple indeed!
Flash, the maple, is looking very Christmasy, with a canopy of green leaves and red samaras (aka keys or whirlybirds).

The big surprise is Spark, the hawthorn, which I thought was dead last month. It's definitely alive! It has put out shoots along the trunk, from buds likely activated by damage to the upper part of the tree (which still looks quite dead).

Leafy shoots are clearly visible at the base of the dead crown. See the one below the lower tie?

There are quite a few shoots emerging, all the way to the base.
Always a fan of the underdog, I told the city arborist that I want to keep this tree ... or maybe now a bush.
Beginnings of a bush?

Tree-following: first the good news

When I returned from my trip, I found that in just two weeks, Flash, the maple, had gone from no leaves to all leafed out, and its flower buds were opening!

But Spike, the hawthorn, is nearly bare. It has just one sickly cluster of leaves. The City arborist is to check our trees in July, and I will get the official determination then. But I'm sure this tree is done for. Last year we were told there was no guarantee on the trees. So if I want a replacement, I will have to buy one.

This is my short just-in-time report for June. Check the latest tree following news. And consider joining us, it's interesting and fun (but sometimes there's bad news).

Tree-following: Let it Snow!!

 

Two days ago, I took a few photos of Flash and Spike, the trees I'm following this year. As you can see, there's nothing left of the little bit of snow that was on the ground a month ago. It's been dry, dry, much too dry!! My too-big-to-water yard is covered in native grasses adapted to xeric conditions: western wheatgrass, alkali sacaton, prairie saltgrass. Even they are struggling after several years of drought. But they're tough. One day, their normally vigorous selves will return.

I water the young trees whenever temps rise above 40º F, to encourage root growth. But there are no obvious changes above ground, it's too early. So I checked their twigs to identify them using buds and scars. Of course I already know what they are. This was a chance to examine features I usually ignore.

I pulled the Winter Tree Finder out of my stack of tree-finders. These are dichotomous keys at their best—simple and fun. One got me hooked on tree id 50 years ago. With the handy twig diagram and friendly descriptions, I was able to find the various buds and scars, and make my way through the key.


For Spike, I didn't get beyond p. 4: "Sometimes a conspicuous feature ... makes identification easier." There were just two candidates with conspicuous thorns, Honey Locust (nope) and Hawthorns (yes), p 21, where I stopped because: "Hawthorns are far too numerous to cover here."
Spike the Hawthorn, with conspicuous thorns and alternate lateral buds.

With Flash, I made good use of the key, moving smoothly through the dichotomous questions. Tree a conifer or not? NOT. Leaf scars alternate or opposite? OPPOSITE. This year's twig more or less than ¼ inch wide? LESS. Leaf scars narrow, inconspicuous, with 3 bundle scars? YES. Terminal bud egg- or cone-shaped? YES. "It is a MAPLE, go to p 48" where I landed amid many maples, none of which grow here (the book covers midwestern and eastern North America).

Unfortunately, the buds and scars of the slender twigs were hard to photograph even though the wind was just a gentle breeze. I didn't dare cut twigs to photograph inside ... these young trees look like they need every twig they have. Here is my best shot, in fact, my only decent one.

Flash the Maple.

I waited until this morning to post, as I was hoping the weather forecast was correct. It was close! Now the scene is very different. The snowfall is going to be "absolutely historic" according to the weather news. If that's the case, then I must be prehistoric! But it IS a lot of snow, and quite wet. The plants and I are happy 😊

Tree-following 2021: Flash and Spike

 
This year, I'm following two trees that moved into my yard last summer. After I paid a modest fee to Rooted in Laramie, two Tiger Tree employees showed up, unloaded, dug, planted, filled and secured them to face the Wyoming wind. I think they did a good job; the trees are still standing. I named them Flash and Spike for their looks.

Flash is a maple with bright red samaras (winged seeds), even in summer when it has dark green leaves. Hard to imagine right now.


Spike is a hawthorn, and will provide dried berries for birds through the winter.

Looking ahead: Flash and Spike at maturity (photos courtesy City of Laramie).

Tree-following: Thinking Ahead

I’m finishing this year’s tree-following by making plans for next year. Which tree should I follow? The Number One Candidate right now is a tree I spotted in October during my monthly visit to 2019's hawthorns. It grows near the west end of the Art Building.
It had such colorful leaves! Of course those leaves are gone now, so on my recent visit I took along the October photo. That way I would know which tree to introduce myself to.

It was cold, windy and getting dark at 4:30. I left my trusty field assistant behind after assuring her she would prefer the warmer cab of the truck.
En route to the west end of the building, I visited briefly with the pair of hawthorns I followed this year. They still had haws, but quite shriveled. I sampled one; it had the texture of fruit leather and just a hint of flavor.
 
With the photo I easily relocated the tree of interest. While I struggled to take a clever photo of print and tree in the wind, several people walked by and smiled. Of course they smiled—being artists, they wouldn't think that what I was doing was the least bit odd.
Assured I had the right tree, I approached it. “Hello, I’m Hollis. What’s your name?” It mimed a response, with branches, leaves and fruit. But I didn’t fully understand.

The branching was opposite (hard to see in wind, sorry):
Leaves had mostly serrated margins and pinnate veins—at least that's what I thought (mystery ahead). The second photo is a zoom from the October shot, click on it for a slightly better view:
There were many clusters of pedicels but only a few with fruit ... which happen to be keys or samaras, doubled like those of maples!
Are you surprised too? These are strange leaves for maples, especially the pinnate venation. Maybe I need to expand my concept of the Aceraceae. Learning awaits.

The other reason for choosing this tree is that it grows next to the Art Building which offers a bright warm whimsical refuge on cold, windy and/or snowy days, or when the mosquitos are bad. Currently there are several new exhibits, including one under construction. But I headed straight to the This and That Galleries because this month both have exhibits featuring plants!
In This I found “Plains Placement”—an exhibition of prints by Ben Nathan. They were made from copper plates etched with leaf designs. Colors were overlaid, and sometimes effects added with a piece of grass with black ink. These works are all in response to a "prompt"—experience in the West.

I was surprised when I walked into That. Flower photos, illustrations and even scientific literature (!) hung on the walls. On a small table lay an explanation by Rebecca Austin and Erin Bentley—artist and scientist. One “needs only look at the field notebooks … to see that when people seek to understand the natural world, they often turn to artistic endeavors … we would like to show that these fields are inherently, if not always obviously, connected.”
For this beautiful illustration of Actaea rubra, they chose Alice Bacon’s 1903 paper Experiment with the Fruit of Red Baneberry “because it was funny.” So of course I had to read more. Turns out Alice performed the experiment on herself! Fortunately she survived, and duly reported her findings.
“Then suddenly the mind became confused and there was a total disability to recollect anything distinctly or arrange ideas with any coherency. On an attempt to talk, wrong names were given to objects, and although at the same time the mind knew mistakes were made in speech, the words seemed to utter themselves independently.”
She experienced pain in many parts of the body. Perhaps scariest of all “the heart fluttered most unpleasantly.” After three hours she was fully recovered but “The experiment was carried no further, as the effects in heart and brain were danger signals not to be ignored.” (I didn't find the funny part.)
