Origin & safety checks

Europe, western Asia, North America. Confirm local native range and restrictions.

Not a toxicity assessment. Verify the exact plant and any edible part with an appropriate local authority; keep uncertain plants away from ingestion.

Check current invasive restrictions with your local plant-health or extension authority. For pets, use the exact botanical name in a veterinary toxicity reference; for potential ingestion or exposure, get appropriate professional advice rather than relying on a design guide.
