Fit it to the site
Draining soil in sun or part shade; avoid wet winter ground.
The source flags aggressive root spread, poisonous parts and high flammability. This is an ornamental reference, not a food-use instruction.
Keep the care in the decision
Monitor root suckers and contain unwanted spread; seasonal dieback varies with climate.
Origin & safety checks
Central & E. U.S.A., Bermuda. Confirm local native range and restrictions.
The source flags poisonous parts. Do not ingest this ornamental plant. 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.
