Imagine a hike in the woods, perhaps the Zaleski State forest, late March, still a few patches of snow but it’s sunny and a promise of warmth in the air. I call this Winter’s twilight. I’ve had enough of winter but it’s not fully Spring yet either, a sort of seasonal twilight before Spring dawns, every now and then, hiking, a flash of green catches my eye, nascent green leaves burst through last season’s brown leaf litter. Occasionally there is a flower as well, but it will not stay around long; it’s very ephemeral. Why?
These so-called Spring ephemerals are not a type of plant, nor a botanical family, but more a specialized botanical way of doing business, plant business, which, like all life, means making more of one’s self, reproducing. The Spring ephemerals have found a way of exploiting the fleeting period of time in the woods that other woodland plants have not discovered yet, Winter’s twilight. They have found a loophole so to speak, a few weeks between hard frozen winter and spring warmth. Soon every dormant tree, shrub and plant will leaf out. Sunlight is suddenly scarce on the forest floor. The Spring ephemerals grab the sunlight before it becomes blocked by bigger and taller things, they flower, attract the few available pollinators and make seed, in the most efficient way imaginable. They are not alone in this risky ecosystem, insect pollinators such as ants not only make fertile seed possible but the insects carry seed of the plant back to their nests where the seed germinates and grows into a new flowering plant. The ant uses the flower nectar and pollen for nutrition, a mutualism or symbiosis. The ephemeral plants have adapted to this twilight niche like cacti have adapted to the desert.
Notice features these Spring ephemerals all have in common: economy, frugality. They are compact, they grow just big enough to flower and produce seed. Then gone, dormant until next season.
The force that through the green fuse drives the flower
Drives my green age, that blasts the roots of trees
Is my destroyer.
And I am dumb to tell the crooked rose
My youth is bent by the same wintery fever.
Dylan Thomas Circa 1930
I wonder. Could Thomas have been thinking of this green fuse, the earliest emerging of all woodland flowering plants, biochemically blasting its way through ice and snow? Notice the net-veining in the spathe, very unusual in a monocot.
The net-veined leaves of blood root are seen very early in spring, the large many-petaled flowers only a week or two later.
Found in very early spring in small patches. The four petals distinguish bluets from spring beauty and other early spring plants.
The name says it all.
Many people will remember this early spring flower as Dentaria lancinata, but no longer. That’s taxonomy for you!
The distinctive, ruby-colored flower of wild ginger grows at the base of the plant and is often hidden from view by the large leaves. This photo shows the big heart-shaped leaves of wild ginger growing over the long, light and dark green striped leaves of waterleaf. It is the roots of wild ginger, not the leaves, that have been used as a substitute for the spice ginger.
Not a very early spring flower, but the small patches of intense red add drama to spring. They seem to favor steep slopes making photography difficult, and also difficult for deer to browse.
The six petals distinguish this wildflower from spring beauty. This is a common plant in woodland areas but is not native to North America. It has been imported from parts of Europe and Asia. It is considered an invasive plant.
Another flowering plant awaited by many as assuring certainty of spring’s arrival. Flowers of this white Trillium remain overlapping at the base, a feature differentiating it from drooping Trillium and Snow Trillium.
Perhaps the wildflower with the most enigmatic common name. The three sepals curve gracefully but do not hang down below the petals like the sepals of Purple Trillium, Trillium recurvatum.
The paddle-shaped leaves with lobed edges make Rue Anemone hard to mistake for other plants with six-petaled flowers.
Another imaginatively named wildflower. It doesn’t take very much imagination to understand the appeal of this plant.
Common later in spring along wooded roadsides.
