Principal seasonal role

Spring

Fit it to the site

Humus-rich, moist but draining soil; neutral to slightly acidic conditions.

Reject an exposed, dry border. Its spreading habit needs review beside very small neighbours.

Keep the care in the decision

Remove damaged foliage as growth resumes. Watch expanding runners and retain space around slower companions. Do not let the planting dry out persistently.

Origin & safety checks

Eastern North America. Local range and taxonomic treatment should be checked.

Toxicity not assessed here. “Children’s garden” tags in a source are not a comprehensive safety assessment.

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.
