These beauties are blooming along the creek in Sabino Canyon (and along the Mt Lemmon highway). Hooker Evening Primrose (Oenothera elata ssp. hirsutissima) is in the - you guessed it - Evening Primrose Family. Their flowers have 4 heart-shaped petals. You can see the reproductive parts - and a spent flower - in the close up.
