Jeffrey Barker visited Stacker Butte, and reports that although few flowers are blooming at the trailhead, there are more to be seen as you gain elevation. The balsamroot and lupine have not really started yet. Some of the varieties currently blooming include: Obscure Buttercup (Ranunculus triternatus), harsh paintbrush (Castilleja hispida), Spring beauty (Claytonia lanceolata),
redstem spring beauty (Claytonia rubra),
small-flowered blue-eyed mary (Collinsia parviflora), upland larkspur (Delphinium nuttallianum), desert shooting star (Dodecatheon conjugens), yellow bells (Fritillaria pudica),
bulbiferous prairie-star (Lithophragma glabrum),
nine-leaf desert parsley (Lomatium triternatum),
Watson`s desert-parsley (Lomatium watsonii),
Hood`s Phlox (Phlox hoodii), and grass widow (Olsynium douglasii var. inflatum) -- this variety is found only in the Gorge near the summit of the Columbia Hills at higher elevations.
