Principal seasonal role

Spring

Fit it to the site

Draining soil in partial or full shade; also tolerates sun.

Not a walkable paving joint or a deep-water plant; a spreading mat does not stay inside a single small circle.

Keep the care in the decision

Allow rooting stems to connect, then edit the boundary where they meet slower neighbours.

Origin & safety checks

South East Canada and Eastern United States. 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.
