Moist, acidic, organic soil, sheltered from drying wind.
NC State reports naturalization and potential invasiveness in some states. Check local status before choosing it; minimum cold range is 6b.
Keep the care in the decision
Keep new roots moist and review slowly spreading rhizomes.
Origin & safety checks
China to Temp. Eastern Asia. Confirm local native range and restrictions.
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.
