Frequently Asked Questions

How accurate are free plant identification apps?

For common garden plants, flowers, and trees, PlantNet and Google Lens achieve 80-90%+ accuracy with good photos. Accuracy decreases for regional species, unusual varietals, and poor-quality photos. iNaturalist with community verification achieves the highest accuracy for confirmed identifications.

Can plant ID apps identify toxic plants?
