Fit it to the site

Average, well-drained soil; flowering is strongest in sun.

Do not fit a mature clump into a narrow front edge or expect instant establishment.

Keep the care in the decision

Choose its position carefully: the deep root makes established plants difficult to move. Keep or remove pods according to the intended display.

Origin & safety checks

Central & Eastern U.S.A. Confirm local native range and restrictions.

The source flags poisonous parts or harmful exposure. Check the exact plant and household exposure before purchase; no edible or pet-safe use is inferred.

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.
