In which our heroine reveals her shocking ignorance about evergreen species of Maine, and vows to do better.
I painted it, but I have no idea what it was. |
I had a visitor to my studio this week, a collector who also
follows my blog. She read about my recent interest in Eastern White Pines, and
mentioned that they are Maine’s state tree. I was surprised, since I don’t see
them in my little corner of the state.
“What is Maine’s state flower?” I asked her, figuring it
would be either the lupine
or rosa
rugosa, both of which grow in wild profusion here. Turns out it’s the cone
of the Eastern White Pine. It was adopted as the state flower in 1895, after it
was used in the National Garland of Flowers at the 1893 World’s Fair.
This may be the Pine Tree State, but its natural trees
include many more broadleaf species (52) than evergreens (14). They’re the same
species as grow in my native New York, but here conifers provide a much greater
percentage of the forest cover.
Sentinel trees, by Carol L. Douglas. Red pines, maybe? |
I don’t know evergreens as well as I know deciduous trees. This week, I’ve decided to learn about them in earnest.
We have more evergreens here because we’re closer to the
taiga, the broad swaths of boreal forests that run in a ring around the North
Pole. (There is no southern-hemisphere equivalent because there isn’t enough
land in the proper latitudes.)
The boreal forests dip into the continental United States where it's mountainous. Here in the northeast, that means along the Appalachians from
northern New York to northern Maine. But mostly, they’re in Alaska and Canada.

Coniferous trees are adapted to the taiga. They shed snow
easily. Their needles are cold- and drought-resistant, with thick waxy coatings
and very little surface area. They can turn photosynthesis on when the
temperature goes above freezing on winter days. Broadleaf plants can’t exploit
brief moments of warmth; they remain dormant after they shed their leaves. That
limits their growing season.
The most obvious difference between spruce and pine is how the needles are
arranged. The needles of spruces attach directly to the branches. Pine trees
have needles in bundles called fascicles.
The needles of balsam firs also grow
individually. However, while spruce tree needles are sharp and flexible, fir needles
are flat and blunt. Balsams are notable for their fragrance.
Another evergreen I painted without first asking its name. How rude! |
Tamaracks,
or larches, are the only deciduous conifer that grows here. Their needles are
three-sided and blue-green. They turn bright yellow in autumn.
I only learned recently that jack pines were a species, not
a description of a weather-beaten tree. These small, drought-resistant trees
have stiff, short needles in bundles of two. Their branches are long and
spreading, forming an open ragged crown. The dark brown bark is
irregularly divided into small scales.
Pitch pines are coastal trees. They have long needles that
come three to a fascicle. Pitch pines sprout needles from their trunks.
White pine also has long needles, but they come five to a
fascicle. Mature, these are huge trees with large cones. Red pines have two
needles to a fascicle, but since both species are big, counting the needles may
not be practical. Red pine bark is, yes, redder than white pine.
Last are the cedars, which have flat, fanned foliage, and
the junipers, which have little blue berries. Just to be annoying, the most
common juniper in the northeast is called the Eastern Red Cedar.
