The wildflowers of Grand Teton National Park usually bloom May through September. There are only about 60 continuous frost-free days a year in Jackson Hole, so the growing season is very short and the dominant blooming flowers change quickly from week to week.
Grand Teton National Park can be separated into three distinct zones: the sagebrush valley, the forest floor, and the alpine zone. Skyrocket gilia, larkspur, and indian paintbrush bloom in the valley as temperatures rise. Flowers like fireweed, columbine, monkshood, and the rare calypso orchid enjoy the moist environments found in forests. The flowers of the alpine zone grow close to the ground and the flowers are very small; examples include moss campion, alpine forget-me-not, and sky pilot.
