Safety

People: The plant is toxic if eaten, especially the rhizome, which contains phloroglucinol compounds such as filicin. Swallowing it can cause nausea, vomiting and diarrhea, and larger amounts can cause more serious effects. Do not eat any part of the plant.
Children: The plant, especially its underground rhizome, contains compounds that can be harmful if chewed or eaten, so keep an eye on small children playing nearby.
Contact allergens: The spores can cause mild irritation to sensitive skin during handling.

Growing it

Propagation: division, spores
When to plant: spring, autumn
Overwintering: Leave the old fronds on until early spring to protect the crown from frost. Cut back the dead foliage just as new growth begins to emerge.
In containers: It grows well in large pots with rich, moisture-retentive soil, provided it is kept out of direct sun.

Division

1. Dig up the clump in early spring.
2. Gently pull the rhizomes apart into smaller sections.
3. Replant immediately in moist, shady soil.

Group these ferns with other moisture-loving shade plants to create a microclimate that retains humidity.
