What is Prairie?

Prairie helps gardeners in any U.S. state identify plants from a photo and instantly see whether they are native, beneficial, invasive, keystone for local wildlife, or endangered — tailored to your state.

How to use

  1. Sign in with Google. Your scans save to your account.
  2. Open Settings and choose your home state (defaults to Illinois).
  3. Tap Identify. Either snap a photo with your camera, or upload up to 12 photos at once from your phone.
  4. Review the result: native status, sun preference, companion plant, keystone species, and conservation status — all specific to your state.
  5. If the plant is non-native or a weed, tap Find native alternatives for state-appropriate swaps.
  6. Your scans live in Plants Identified. Search, filter, and delete from there.

Tips for better identifications

  • Fill the frame with one leaf, flower, or fruit — not the whole bed.
  • Shoot in daylight with even light; avoid blurry close-ups.
  • Capture distinctive features (leaf shape, vein pattern, bloom).
  • If the AI returns "Unknown," try another angle or a clearer feature.

Identifications are powered by Google's Gemini 3 Flash multimodal model and cross-referenced against state natural-resources data. Plant info is informational only — please consult local extension offices before management decisions, and never eat a plant identified only by an app.
