Butte Primrose, Gumbo Primrose
Showy, sweet-scented white (fading to pink) blossoms, up to 8 cm across open above this low-growing leafy rosette, found on dry hillsides of gumbo or clay soil. Blossoms occur through summer from June to August. The flowers, which are pollinated by moths, open at night, and each blossom lasts only one day.
The Blackfoot called this plant Ap-aks-ibokn for “wide leaves” or Oks-pi-poku for “sticky root”, and used the crushed root, applied wet, to sores and swellings. (Johnston 48)
