From A Garden of Marvels by Ruth Kassinger:
“Deciduous trees… have evolved to deal with surviving cold months. In winter, the energy that a tree’s leaves are able to generate during short daylight hours is less than the energy required to maintain cell function in the leaves. In addition, the loss of water through transpiration exceeds the amount that the roots are able to absorb when groundwater is locked up in ice. So, in autumn, deciduous trees cut their losses. First, thanks to hormonal signals, they drain the sucrose from their leaves and send it to their roots and branches for storage. Then they seal off the leaves at their bases with a corky substance. Without water and nutrients, the leaves’ cells die. In the spring, the trees send stored sugar dissolved in water up the xylem to fuel the growth of new leaves and branches.”
One must have a mind of winter
To regard the frost and the boughs
Of the pine-trees crusted with snow;
And have been cold a long time
To behold the junipers shagged with ice,
The spruces rough in the distant glitter
Of the January sun; and not to think
Of any misery in the sound of the wind,
In the sound of a few leaves,
Which is the sound of the land
Full of the same wind
That is blowing in the same bare place….
January is a great month for hunting down those natural shapes of things that are most apparent only in the winter. For this post (and the next one) I scoured the trees for shreds of Japanese Maple leaves, those that still clung on and held an interesting form despite many days of rain, wind, and cold. Their tenaciousness is admirable — don’t you think?
Even though it was a cloudy day, there was enough sunlight breaking through so that some of the leaves — all but those in the last three images — got touched with a bit of backlighting, just enough so that they looked like the were glowing against the blue-gray skies.
Thanks for taking a look!
