Wildflowers grow at unusually low elevations at Silver Star Mountain, as a result of fires, wind, and rocky subsoil. There are more than 100 types of wildflowers and flowering shrubs on the volcano, such as heather, star tulip, tiger lily, Grey's loveage, hairbell, bear grass, western bistort, columbine, Avalanche lily, broadleaf lupine, wooly sunflower, Cardwell's penstemon, Indian paintbrush, phlox, balsamroot, and glacier lilies. Trails around the volcano, in addition to offering views of wildflower-cover slopes, pass through thickets of huckleberry, as well as forests with noble fir.
