Yes. Myers asparagus ferns are toxic to humans and common household pets if ingested. The fern’s red berries contain sapogenin, a steroid found in many plants. Ingesting these berries can cause vomiting, diarrhea, and abdominal pain. Additionally, the fern’s leaves contain sap that may cause skin and eye irritation. We recommend wearing gloves when handling a Myers asparagus fern and keeping the plant out of reach of children and pets.
