This page provides information about various plants referred to as "spleenworts," focusing on characteristics, distribution, and other relevant details as described in the provided text. The text covers multiple species with similar common names, so pay close attention to the scientific names where available.
Considerations for Pets
- Some spleenworts are described as having "hairs" on the petioles and stems. While not inherently dangerous, the presence of hairs could potentially cause mild irritation if ingested or contacted by sensitive animals.
Considerations for Children
- The text mentions "small parts" in the description of some spleenworts. These small parts, like leaflets, could be a choking hazard for young children.
