Grand Teton National Park is a national park in northwestern Wyoming. At approximately 310,000 acres (480 sq mi), the park includes the major peaks of the 40-mile-long Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only 10 miles south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost 18,000,000-acre Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems.—Wikipedia
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.-NPS
