Flowers in bloom include arrowleaf balsamroot (Balsamorhiza sagittata), fiddleneck (Amsinckia sp.), cushion phlox (Phlox hoodii), bitterbrush (Purshia tridentata), and threadstalk locoweed (Astragulus filipes).

Buds are present on orange globe mallow (Sphaeralcea munroana) and red desert paintbrushes (Castelleja sp.), with blossoms expected in the next 2-3 weeks.

Painted Hills Unit

Bitterroot (Lewisia rediviva) is starting to appear in large numbers, with more blossoms expected over the next week. Bitterbrush (Purshia tridentata) is in full bloom. A few scattered golden bee plants (Cleome platycarpa) are blooming in the flat areas, but no flowers are present on the hills. A small number of prairie stars (Lithophragma bulbifera), Fiddleneck (Amsinckia sp.), and false dandelion (Microseris troximoides) are also in bloom. Common larkspur (Delphinium nuttallianum) are in bloom in isolated stands.

Hedgehog cactus (Pediocactus simpsonii) are starting to bloom in one of the fenced off areas of the unit. More blossoms are expected over the next 2-3 weeks. Visitors interested in seeing them in bloom should visit our Ranger Guided Activities page for more information on scheduled hikes that enter this area.


Sheep Rock Unit

Arrowleaf balsamroot (Balsamorhiza sagittata) is blooming in multiple locations in the unit.

False dandelion (Microseris troximoides), pepper grass (Lepidium perfoliatum), and nine-leaf desert parsley (Lomatium triternatum) are blooming at the Cant Ranch. (Although not a wildflower, it is worth noting that the lilacs at the Ranch House are in full bloom.)

Red osier dogwood (Cornus stolonifera), Columbia hawthorn (Crategus columbiane), western serviceberry (Amelanchier alnifolia), chokecherry (Prunus virginiana), bitterbrush (Purshia tridentata), and golden current (Riber aureum) are all blooming along the river's edge.
