Poison Oak

Poison Oak
“Poison Oak” — Poison oak leaves transition to fall colors in the deep shade of a redwood forest.

Aspens are not the only plants producing fall color here in California. The ubiquitous poison oak plants become even more red and start to pick up a bit of yellow/brown late in the season. The plant is widespread in wild areas of the state, ranging from coastal bluffs to oak forests to scrub brush, and California hikers soon learn how to identify it. The red leaves are a clue, but the oak shaped leaves in groups of three can mostly confirm it. (Though some wild berry plants have a similar appearance — but their stems have thorns, which are lacking on poison oak.)

The plant is flexible and grows in various ways. It can grow almost like a bush. Sometimes it is found in what amount to poison oak thickets. Low growing plants are sometimes found underneath other plants. It vines and can send runners up the trunks of trees, as is the case here. I photographed this example in a dark part of a forest at the Pfeiffer Big Sur State Park in the town of Big Sur.

Poison Oak Leaves, Last Day of Summer

Poison Oak Leaves, Last Day of Summer

Poison oak leaves on the last day of summer against a backgrouind of branches and early autumn colors – Calero Hills, California.

My last-day-of-summer morning hike at Calero Park began early and in cloudy weather – but the overcast saturated the colors on some of the early fall colors, including the leaves on this poison oak bush on a grassy hillside.

Yes, I was careful not to get too close! I shot this with a telephoto lens…
