Fit it to the site

Rich, draining soil in partial to deep shade; tolerates some dryness. Protect from harsh winter winds.

Reject direct, scorching sun or a winter climate outside the verified range. The source description says up to 2 ft, while structured dimensions reach 3 ft; this record uses the larger envelope.

Keep the care in the decision

Inspect water through active growth and remove damaged foliage when needed. Expanding rhizomes may fill a wider area over time; keep the edge under review.

Origin & safety checks

Japan. Check local suitability and restrictions.

Toxicity not assessed in this record. Do not infer edibility from its common name or traditional uses.

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.
