On 23 September 2018, I went into Roy's Redwoods to look for examples of poison oak mimicry. I'd learned in California Naturalist training last weekend that poison oak often grows to resemble the plants around it, and I wanted to see this for myself.
Following are examples of how poison oak can change the shape, color, and texture of their foliage to resemble other plants growing nearby. Each pair of photos was taken from plants growing in close proximity to each other.
