Hooker’s evening primrose (Oenothera elata hirsutissima) is tall leafy plant (up to six feet tall) that flashes color late in the summer. From late July and onward you can often find yellow flowers with heart shaped petals at the very top of this plant. Look for this plant in wetter areas within Calico Basin, Pine Creek, First Creek, and other spring drainages. The seeds of this evening primrose were collected and grounded into a meal and either eaten raw or toasted by Natives. The plant was named after William Jackson Hooker, a botanist in the 1800s that ran gardens and established the Journal of Botany in America.
