ABOUT OREGONFLORA
OregonFlora at Oregon State University is the primary steward of Oregon's botanical information. Since 1994, OregonFlora has developed the Flora of Oregon (volumes 1 & 2 published 2015 and 2020). Visit oregonflora.org to explore all ~4,700 Oregon vascular plants with interactive tools, maps, and images.
The Oregon Wildflowers app has been both educational and a lot of fun. We use it on every hike here in Oregon. The results from filtering are almost always on target, sometimes even without flowers! We use the helpful photos and range map (where the species has been recorded) to confirm tentative IDs. Plus the app supports the fabulous Oregon Flora Project. (BTW, I'm a professional botanist, like another reviewer, but I think this app is a gem.)
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.
Great app by OSU

I use this app frequently both for identifying plants in the wild and for garden planning. My one suggestion is that they switch the iNaturalist integration to their updated app.
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.
