Airbrushed with Crimson

Davis Knotweed, Lassen Volcanic National Park (10/4/18) Shanda Ochs

Davis Knotweed, Lassen Peak Trail (10/4/18) Shanda Ochs

It almost appears as if the trailhead to Lassen Peak was airbrushed with crimson in this photograph by Shanda Ochs, taken yesterday afternoon.

The color, in fact, comes from Davis Knotweed (Aconogonon davisiae). There are 27 varieties of knotweed native to California. Douglas knotweed grows in Lassen Volcanic National Park at this elevation.

Shanda said, “It was spectacular with the fog which made the color pop!” The dusting of frost on the volcano adds to the photo’s drama.

Notice the golden-orange ground cover near the base of the trailhead. The source of that color remains unidentified. Though, Fall Color creds go to the first person to comment and identify it.
