Fit it to the site

Keep the care in the decision
Keep roots mulched and avoid repeated drying during establishment.
Origin & safety checks
Central & Eastern U.S.A. Confirm local native range and restrictions.
Pet safety and edible uses are not assessed; verify the exact botanical name with a suitable local authority.
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.
