The Sansevieria Whale Fin (Sansevieria masoniana) is a bold and architectural plant recognized for its single, enormous paddle-shaped leaf that resembles a whale’s fin. Its deep green surface is often mottled with lighter patterns, giving it a sculptural, modern appeal perfect for minimalist or contemporary spaces.

This rare and resilient plant thrives on neglect—making it ideal for beginners and collectors alike. It’s drought-tolerant, air-purifying, and adaptable to a wide range of light conditions.

☀️ Light: Tolerates low to bright indirect light. Best color and growth occur in bright, indirect light.

💧 Water: Water sparingly. Allow the soil to dry completely between waterings. Overwatering is the most common cause of damage.

🌫️ Humidity: Average indoor humidity is perfect. Avoid misting.

📏 Size: Each fin-like leaf can grow 2–4 feet tall and up to 6 inches wide.

🐾 Pet-friendly?: ❌ Not pet friendly (toxic if ingested).

🪴 Where It Looks Best: Excellent as a floor or tabletop plant. Its dramatic, upright form adds structure to any room, office, or modern plant display.

💡 Pro Tip: Use a cactus or succulent soil mix for excellent drainage. Turn the pot occasionally for even growth and leaf balance.
