Flowers of Florissant Fossil Beds National Monument

The color that wildflowers add to Rocky Mountain scenery is a favorite among summer sights in Colorado. Learning names for the wide variety of brilliant flowers is challenging and fun. Some of the most common flowering plants found at the Monument are described in this guide.

Colorado can be divided into several life zones defined by plants, animals and elevation. The plains life zone occupies half of the state. At the edge of the Rockies the foothills zone begins. Florissant Fossil Beds National Monument lies within the montane zone. Between the 7500 feet and 9500 feet the montane stretches to the subalpine life zone. Timberline marks the point where subalpine meets alpine. The montane zone supports wildlife such as Abert squirrels and elk. Many plants and animals found in the montane also occur in the plains, foothills and subalpine zones. You will be able to use the Fossil Beds wildflower guide in other areas of the Rocky Mountains.

The wildflowers in this guide are separated into four color categories. Identifying characteristics are give in the following order: approximate blooming season, height range, life zones (foothills, montane, etc.) habitat (meadows, dry hillsides, etc.), distinctive characteristics, interesting facts, scientific name, plant family.

Enjoy the wildflowers of Florissant Fossil Beds National Monument and please leave them for others to enjoy. The National Park Service is charged with preserving natural and cultural areas for the education and enjoyment of the public. Petrified wood, carbon fossils, animals and plants are protected here and may not be harmed or removed.

Wildflower programs are held daily at the monument and special wildflower seminars are scheduled throughout the summer. Ask at the visitor center about our programs.
