Rocky Mountain Region

The Rocky Mountain Region of the U.S. Forest Service includes eleven national forests and grasslands in Colorado, Wyoming, South Dakota, Nebraska, and Kansas. The ecological and biological diversity on these lands is amazing: ranging from the many peaks above 14,000 feet in elevation down from alpine tundra, through coniferous and aspen forests, to pinyon-juniper and sagebrush, or expansive grasslands as low as 2,500 feet. Wildflower viewing opportunities abound. Peak blooming season generally progresses from lower to higher elevations.

What's Bloomin' on the Black Hills National Forest?

By Chelsea Monks Forest Botanist, Black Hills National Forest

I wanted to make sure that you were aware of the webpage the Black Hills National Forest maintains every summer. It is called "What's Bloomin' in the Black Hills?" and features lists of the current blooming species along with links to photos. The lists and photos come from botanists and others across the Forest. I try to update the site every other week.

Tall Forb Community of the Intermountain West

Few landscapes can match the beauty and profusion of wildflowers found in the lush, subalpine mountain parklands of the interior western States. Among the most unexpected and rarest of the high elevation plant communities is one dominated solely by large, luxuriant wildflowers, commonly referred to as the Tall Forb Community type.
