The air was cool on Saturday morning, and this tiger swallowtail let us approach quite close as it basked in the strong sunlight. With the pale forest litter as a backdrop, it was difficult to spot, even from three feet away. Only with all intermediate shades between dark and light removed (with the “threshold” effect in Photoshop) does the pattern of its wings emerge clearly, just like the children’s game where someone says “hot” or “cold” to lead someone else to a hidden prize. Having only two options can really clarify.
The purple trillium comes in two colors, purple and light yellow. The latter seems to be controlled by a recessive gene, like blue versus brown eyes in humans. Given the trillium’s three leaves, three sepals, three petals, and three stigmas, though, it seems a little surprising that there isn’t a third color option. Then again, most trillium species only have one.
Cut down a trillium for any reason — even if only for the cut flower — and it can take years to recover, if ever. Like many perennial native wildflowers of the Appalachians, trilliums spread with glacial speed, depending almost exclusively on ants to carry their seeds back to their colonies and toss them out in their middens after eating the protein-rich bribe (the eliasome). And ants don’t tend to walk great distances, at least not in human terms. “This type of seed dispersal is termed myrmecochory from the Greek ‘ant’ (myrmex) and ‘dispersal’ (kore),” says the Wikipedia.
A freshly opened flower of yellow mandarin is the same monochome green as its leaves. Young as it is, though, it’s already bound by a few strands of spider web. The flowers must move quickly before the forest canopy fills out and robs them of sunlight; those whose lives are linked to theirs, like the ants and the spiders, must move even more quickly. But I suppose it is because they have so little time each year in which to flourish that these wildflowers’ long-term progress is so slow.
So musing, we sauntered slowly up the hollow.
