Perityle incana, endemic to Guadalupe island.  Get's a few feet all around, blooms spring summer.  Looks like a smaller version of Eriophyllum nevinii.  Photo by Brad Hollingsworth, Perityle growing on side of cliff on Guadalupe Island, Baja California.  Like the other plants in this Blog it likes sun, tolerates some shade.  It's not a shade plant per se, even though the sun angle at the moment this photo was taken has it in the shade.
