Scientific names · Common names · Families · Contact

Eastern Colorado Wildflowers contains photographs and information for plants growing east of the Continental Divide in Colorado. Species listed in Weber and Wittmann's Colorado Flora: Eastern Slope, 3rd Edition are included.

Species are listed alphabetically by Scientific names, Common names, or Families. Names are those used by Weber and/or USDA Plants Database.

Vegetation zones follow those described by the Colorado Native Plant Society:

Plains: 3500 to 6500 feet
Foothills: 6500 to 8000 feet
Montane: 8000 to 10,000 feet
Subalpine: 10,000 to 11,500 feet
Alpine: above 11,500 feet (tree line)

Times of flowering are estimates based on references and my own observations. They can vary depending on elevation and climate.

Great effort has been made to correctly identify species. If you believe a species has been misidentified, please send an email and I will make corrections. This feedback will strengthen the site as a resource.

Eastern Colorado Wildflowers currently contains over 300 plant species. Over time, I hope to greatly expand the list of species and continually improve upon the quality of the photographs.

Thank you to Sara, Kate and Charlie for their patience during family hikes and for allowing me to dominate our computer for several months. Thank you also to my friends and colleagues who have assisted with plant identification. And to my parents, whose copy of Eliot Porter's Birds of North America was an inspiration.
