The UK has one of the most varied gardening cultures in the world — allotments, cottage gardens, balcony jungles, RHS show gardens. A plant identifier that works for a Tudor herb border has to also handle a fiddle leaf fig in a Manchester flat. Here is the short list for 2026.

- Handles UK natives + tropicals equally. GPT-4 Vision identifies a foxglove as confidently as a monstera, which matters because most UK homes mix garden cuttings with houseplant collections.
- Disease diagnosis for British conditions.Black spot on roses, powdery mildew on courgettes, and rust on hollyhocks are the most common UK plant problems — all three are in the app's top-confidence detection set.
