When the weather is cool, spring is what you make of it.
The red oregon grape leaves among the poison ivy berries I found growing along Kalamalka Lake, are attracting warm light, invisible to my eye, while the yellow berries of the poison ivy (a form of cashew) keep humans and other predators out, even while signalling their presence to birds, who survive the spring partly because of this selection. As a result, both species are able to spread and take in more of the spring, effectively intensifying it — for all.
