Mother-in-law’s tongue is named after its long, lashing shape (not unlike the tongue of a mother-in-law!). This plant, the Sansevieria trifasciata, is to be differentiated from other type of “Mother-in-law” vs. “Mother-in-law plant.” This common house and office plant is also called the Good Luck plant or Golden Bird’s Nest. When ingested by pets, it can result in gastrointestinal signs (e.g., drooling, vomiting, diarrhea, etc.).
