Pathfinder

 Pathfinder (Adenocaulon bicolor)

Pathfinder, trailplant or Adenocaulon bicolor is the plant that can be found in redwood forest and probably other forests as well. The plant is fairly easy to recognize: it has big triangular leaves that are green on the outside and whitish on the inside. If you walk on the leaves and intentionally turn them over while stepping on them, you'll see the marked trail of white underside, hence the name pathfinder.

Pathfinder blooms but the flowers are very small and inconspicuous but at least they have tall stems.
