The Oregon Flora Project at Oregon State University presents the Oregon Wildflowers plant identification app for smart phones and tablets. The app provides photographs, range maps, bloom period, and detailed descriptions for more than 1050 common wildflowers, shrubs, and vines that occur throughout Oregon and adjacent areas of California, Washington and Idaho. The selection and use of this curated data, developed by botanists, provides users with the most accurate information available that will in turn allow them to readily identify the plants they see statewide.

Designed for both budding wildflower enthusiasts and experienced botanists, Oregon Wildflowers will appeal to individuals who are interested in the names and natural history of the plants they encounter. It is an excellent educational tool for all ages to learn about botany, plant communities, and ecology using the plants found throughout Oregon. Each of the 1054 plants profiled has multiple photographs, distribution maps, and a detailed description. The majority of species included are native, and introduced species common to the region are also covered. Plant hunters can use the app to identify species in all ten of Oregon’s diverse ecoregions.

Users can browse through the stunning photographs of plants organized by common name, scientific name, or by family to select a plant and access the related information. However, most users will likely use the identification key that is the core of the app to identify an unknown plant of interest.

The key's interface allows users to select from twelve illustrated categories: geographic region, type of plant (e.g., wildflower, vine, shrub), flower features (flower color, number of petals, inflorescence shape, flowering month), leaf features (arrangement on plant, leaf type, leaf shape, leaf margin), plant size, and habitat. The key’s characters for each species are based on the descriptions prepared for the Flora of Oregon (published by the Oregon Flora Project at OSU).

Once downloaded, the app does not need an internet or network connection to run so you can use it no matter how remote your wanderings take you.

The Oregon Flora Project is midway through compiling the comprehensive Flora of Oregon, a three-volume manual of the vascular plants of Oregon, covering all native and naturalized taxa (species, subspecies, and varieties) that occur in the wild without cultivation. Volume 1 (floristic treatments of Pteridophytes, Gymnosperms, and Monocts) was published in 2015. Volume 2 will be out in late 2020 (treatments of plant families Adoxaceae through Fagaceae), and Volume 3 (treatments of plant families Garryaceae through Zygophyllaceae) will follow. The Oregon Wildflowers app presents a subset of this information—over 23% of the state’s unique plants—formatted for mobile devices and easily mastered by a wide audience. Users will find extensive information on the ecoregions and plant habitats of Oregon, a glossary of botanical terms, and descriptions of each plant family represented in the app. The Oregon Flora Project website ( contains additional information about all of Oregon’s 4,560 vascular plants.

A portion of the revenues received from the app goes to develop the floristic knowledge base that lets us create quality tools to inform the public about Oregon's plants.

Another super High Country

Have been using High Country flower apps for some time and when Oregon came out, I had to grab it. I used to live in the Portland area, but now I’m a hop skip and a jump from Eastern Oregon which has very, very different flora. Easy to have with me if I’m just out and about and spot something interesting. Don’t have to try to remember what it looked like until I get home and grab a guide book.

Advanced ID capability

My favorite thing about apps like this is the use of multi trait databases instead of the old binary keys. Much more success at identifying flowers. Also excellent photos.

Best flower identification app ever!

Every Oregonian who enjoys wildflowers should get this app. You can Id flowers by characteristics, create a lifetime list, and more. It's resident on your phone so you don't need wireless signal to use it. And this is science, folks, not some funky free thing that is worth what you paid for it (0).
