Tips for Identifying Flowers in Washington
- Time it right. Most wildflowers in Washington peak in May–June. Visit the same spot every two weeks during peak season to catch different species.
- Photograph the bloom face-on. A close, well-lit shot of the open flower gives the AI the strongest identification signal.
- Add a leaf shot. If the first identification is uncertain, a second photo of a leaf usually resolves it.
- Note the habitat. Forest, meadow, roadside, wetland — habitat alone narrows the candidates significantly.
- Stay on trail in public lands. Take only photos. Many state and federal lands prohibit picking flowers.
