Gemini thinks it's peony...

Note: Gemini is usually very good at identifying plants but some plants are notoriously difficult for anyone to pin down except horticulturalists (e.g. experts). For example, Pothos vs. Heartleaf Philodendron or more dangerous, Queen Anne's Lace vs Poison Hemlock. AI also has trouble identifying grasses (in general) because many can look the same from a picture. Even close up! Yet a human (in person) would be like, "these two grasses are nothing alike!"
It's all about pattern matching. If two leaves from two different plants have the same appearance and growth pattern, AI can easily get it wrong. In general, though, it usually does a really good job.
