Poison oak/ivy?

Asked July 17, 2015, 12:16 PM EDT

We are wondering if the plant in these photos is poison oak (or ivy). Growing near driveway in Grand County, Colorado, elevation about 8800 feet.

The plants in your photos are not poison ivy or poison-oak.
Watch for any flowers - if white they may be a type of wild strawberry. If yellow they may be a strawberry relative called potentilla.

Thank you! That's a relief, because we have a lot of it. Do you know whether either poison plant, or any other plant that would cause an allergic skin reaction, is found at this elevation in Grand County?

A plant called Stinging Nettle (Urtica gracilis) is found in Grand County. It has hairs on the leaves that contain skin irritants like histamines. Stinging nettle would be more likely near or along streams or irrigation ditches.

You might visit with your local CSU Extension office to discuss what plants might be causing your dermatitis.
