Origin & safety checks

Garden hybrid first cultivated in the Netherlands; not a wild native-species recommendation.

Toxicity and pet safety are not assessed here. An ornamental record is not an edible-use recommendation.

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.
